Aims. Open reduction and plate fixation (ORPF) for displaced proximal humerus fractures can achieve reliably good long-term outcomes. However, a minority of patients have persistent pain and stiffness after surgery and may benefit from open arthrolysis, subacromial decompression, and removal of metalwork (ADROM). The long-term results of ADROM remain unknown; we aimed to assess outcomes of patients undergoing this procedure for stiffness following ORPF, and assess predictors of poor outcome. Methods. Between 1998 and 2018, 424 consecutive patients were treated with primary ORPF for proximal humerus fracture. ADROM was offered to symptomatic patients with a healed fracture at six months postoperatively. Patients were followed up retrospectively with demographic data, fracture characteristics, and complications recorded. Active range of motion (aROM), Oxford Shoulder Score (OSS), and EuroQol five-dimension three-level questionnaire (EQ-5D-3L) were recorded preoperatively and postoperatively. Results. A total of 138 patients underwent ADROM; 111 patients were available for long-term follow-up at a mean of 10.9 years (range 1 to 20). Mean age was 50.8 years (18 to 75);79 (57.2%) were female. Mean time from primary ORPF to ADROM was 11.9 months (6 to 19). Five patients developed
Prospective data on hip fracture from 3686 patients at a United Kingdom teaching hospital were analysed to investigate the risk factors, financial costs and outcomes associated with deep or
In order to define the predisposing factors and outcome of infected arthroplasty of the knee, a retrospective analysis of a consecutive series of 471 knee arthroplasties was performed. There were 23 cases of
Aims. Open tibial fractures are limb-threatening injuries. While limb loss is rare in children, deep infection and nonunion rates of up to 15% and 8% are reported, respectively. We manage these injuries in a similar manner to those in adults, with a combined orthoplastic approach, often involving the use of vascularised free flaps. We report the orthopaedic and plastic surgical outcomes of a consecutive series of patients over a five-year period, which includes the largest cohort of free flaps for trauma in children to date. Methods. Data were extracted from medical records and databases for patients with an open tibial fracture aged < 16 years who presented between 1 May 2014 and 30 April 2019. Patients who were transferred from elsewhere were excluded, yielding 44 open fractures in 43 patients, with a minimum follow-up of one year. Management was reviewed from the time of injury to discharge. Primary outcome measures were the rate of deep infection, time to union, and the Modified Enneking score. Results. The mean age of the patients was 9.9 years (2.8 to 15.8), and 28 were male (64%). A total of 30 fractures (68%) involved a motor vehicle collision, and 34 (77%) were classified as Gustilo Anderson (GA) grade 3B. There were 17 (50%) GA grade 3B fractures, which were treated with a definitive hexapod fixator, and 33 fractures (75%) were treated with a free flap, of which 30 (91%) were scapular/parascapular or anterolateral thigh (ALT) flaps. All fractures united at a median of 12.3 weeks (interquartile range (IQR) 9.6 to 18.1), with increasing age being significantly associated with a longer time to union (p = 0.005). There were no deep
Aims. The aim of this study was to report a retrospective, consecutive
series of patients with adolescent idiopathic scoliosis (AIS) who
were treated with posterior minimally invasive surgery (MIS) with
a mean follow-up of two years (. sd. 1.4; 0.9 to 0 3.7). Our
objectives were to measure the correction of the deformity and record
the peri-operative morbidity. Special attention was paid to the
operating time (ORT), estimated blood loss (EBL), length of stay
(LOS) and further complications. Patients and Methods. We prospectively collected the data of 70 consecutive patients
with AIS treated with MIS using three incisions and a muscle-splitting
approach by a single surgeon between June 2013 and February 2016
and these were retrospectively reviewed. There were eight male and
62 female patients with a mean age of 15 years (. sd. 4.5
) with a mean body mass index of 19.8 kg/m. 2. (. sd. 5.4).
The curves were classified according to Lenke; 40 curves were type
1, 15 were type 2, three were type 3, two were type 4, eight were
type 5 and two were type 6. Results. The mean primary Cobb angle was corrected from 58.9° (. sd. 12.6°)
pre-operatively to 17.7° (. sd. 10.2°) post-operatively with
a mean correction of 69% (. sd. 20%, p < 0.001). The mean
kyphosis at T5 to T12 increased from 24.2° (. sd. 12.2°) pre-operatively
to 30.1° (. sd. 9.6°,
p < 0.001) post-operatively. Peri-operative (30 days) complications
occurred in three patients(4.2%): one subcutaneous haematoma, one
deep venous thrombosis and one pulmonary complication. Five additional complications
occurred in five patients (7.1%): one
Between 1993 and 2008, 41 patients underwent total coccygectomy for coccydynia which had failed to respond to six months of conservative management. Of these, 40 patients were available for clinical review and 39 completed a questionnaire giving their evaluation of the effect of the operation. Excellent or good results were obtained in 33 of the 41 patients, comprising 18 of the 21 patients with coccydynia due to trauma, five of the eight patients with symptoms following childbirth and ten of 12 idiopathic onset. In eight patients the results were moderate or poor, although none described worse pain after the operation. The only post-operative complication was
We report our experience of treating 17 patients with benign lesions of the proximal femur with non-vascularised, autologous fibular strut grafts, without osteosynthesis. The mean age of the patients at presentation was 16.5 years (5 to 33) and they were followed up for a mean of 2.9 years (0.4 to 19.5). Histological diagnoses included simple bone cyst, fibrous dysplasia, aneurysmal bone cysts and giant cell tumour. Local recurrence occurred in two patients (11.7%) and
We report our early experience with a new peri-acetabular reconstruction endoprosthesis used for pelvic reconstruction after tumour resection. The outcome of 21 patients who underwent limb salvage following type II pelvic resection and reconstruction using the peri-acetabular reconstruction prosthesis between 2000 and 2006 was retrospectively reviewed. This prosthesis was designed to use the remaining part of the ilium to support a horizontally placed acetabular component secured with internal fixation and bone cement. Into this device a constrained acetabular liner is positioned which is articulates with a conventional femoral component to which a modular extension and modular head are attached. The mean follow-up was 20.5 months (1 to 77). The most common complications were deep
There are few reports of the treatment of lumbar tuberculous spondylitis using the posterior approach. Between January 1999 and February 2004, 16 patients underwent posterior lumbar interbody fusion with autogenous iliac-bone grafting and pedicle screw instrumentation. Their mean age at surgery was 51 years (28 to 66). The mean follow-up period was 33 months (24 to 48). The clinical outcome was assessed using the Frankel neurological classification and the Kirkaldy-Willis criteria. On the Frankel classification, one patient improved by two grades (C to E), seven by one grade, and eight showed no change. The Kirkaldy-Willis functional outcome was classified as excellent in eight patients, good in five, fair in two and poor in one. Bony union was achieved within one year in 15 patients. The mean pre-operative lordotic angle was 27.8° (9° to 45°) which improved by the final follow-up to 35.8° (28° to 48°). Post-operative complications occurred in four patients, transient root injury in two, a
We carried out a retrospective review of 47 intra-articular fractures of the calcaneum treated by open reduction and internal fixation in 45 patients by a single surgeon between 1993 and 2001. The fractures were evaluated before operation by plain radiographs and a CT scan using Sanders’ classification. Osteosynthesis involved a lateral approach and the use of the AO calcaneal plate. The mean follow-up was for ten years (7 to 15). Clinical assessment included the American Orthopaedic Foot and Ankle Society Score (AOFAS), the Creighton-Nebraska Score, the Kerr, Prothero, Atkins Score and the SF-36 Health Questionnaire. The radiological evaluation consisted of lateral and axial views of the os calcis. Arthritic changes in the subtalar joint were assessed with an internal oblique view and were graded using the Morrey and Wiedeman scale. There were 18 excellent (38.3%), 17 good (36.2%), three fair (6.3%) and nine poor (19.2%) results. Five patients had a
There are few reports on the treatment of pyogenic lumbar spondylodiscitis through the posterior approach using a single incision. Between October 1999 and March 2003 we operated on 18 patients with pyogenic lumbar spondylodiscitis. All underwent posterior lumbar interbody fusion using an autogenous bone graft from the iliac crest and pedicle screws via a posterior approach. The clinical outcome was assessed using the Frankel neurological classification and the criteria of Kirkaldy-Willis. Under the Frankel classification, two patients improved by two grades (C to E), 11 by one grade, and five showed no change. The Kirkaldy-Willis functional outcome was excellent in five patients, good in ten and fair in three. Bony union was confirmed six months after surgery in 17 patients, but in one patient this was not achieved until two years after operation. The mean lordotic angle before operation was 20° (−2° to 42°) and the mean lordotic angle at the final follow-up was 32.5° (17° to 44°). Two patients had a
Hip and groin injuries are common in athletes
who take part in high level sports. Adductor muscle tendon injuries represent
a small but important number of these injuries. Avulsion of the
tendons attached to the symphysis pubis has previously been described:
these can be managed both operatively and non-operatively. We describe
an uncommon variant of this injury, namely complete avulsion of
the adductor sleeve complex: this includes adductor longus, pectineus
and rectus abdominis. We go on to describe a surgical technique
which promotes a full return to the pre-injury level of sporting
activity. Over a period of ten years, 15 high-level athletes with an MRI-confirmed
acute adductor complex avulsion injury (six to 34 days old) underwent
surgical repair. The operative procedure consisted of anatomical
re-attachment of the avulsed tissues in each case and mesh reinforcement
of the posterior inguinal wall in seven patients. All underwent a
standardised rehabilitation programme, which was then individualised
to be sport-specific. One patient developed a
We have carried out a retrospective review of 11 Souter-Strathclyde primary total elbow arthroplasties in ten patients with osteoarthritis, over a period of nine years. The diagnosis was primary osteoarthritis in nine elbows and post-traumatic arthritis in two. The mean follow-up was 68 months (15 to 117). Although no patient was symptomatic, radiological review revealed evidence of loosening affecting three humeral and two ulnar components, one of which subsequently failed and was revised at 97 months. There were no dislocations, deep infections or mechanical failures. Complications included two
Conventional growing rods are the most commonly
used distraction-based devices in the treatment of progressive early-onset
scoliosis. This technique requires repeated lengthenings with the
patient anaesthetised in the operating theatre. We describe the
outcomes and complications of using a non-invasive magnetically
controlled growing rod (MCGR) in children with early-onset scoliosis.
Lengthening is performed on an outpatient basis using an external remote
control with the patient awake. Between November 2009 and March 2011, 34 children with a mean
age of eight years (5 to 12) underwent treatment. The mean length
of follow-up was 15 months (12 to 18). In total, 22 children were
treated with dual rod constructs and 12 with a single rod. The mean
number of distractions per patient was 4.8 (3 to 6). The mean pre-operative
Cobb angle was 69° (46° to 108°); this was corrected to a mean 47°
(28° to 91°) post-operatively. The mean Cobb angle at final review
was 41° (27° to 86°). The mean pre-operative distance from T1 to
S1 was 304 mm (243 to 380) and increased to 335 mm (253 to 400)
in the immediate post-operative period. At final review the mean distance
from T1 to S1 had increased to 348 mm (260 to 420). Two patients developed a
The effects of using a tourniquet during total knee arthroplasty were studied in 80 patients randomly allocated to two groups, either with or without a tourniquet. The groups were similar in mean age, gender, preoperative knee score and radiographic grading and the patients were all operated on by the same surgeon using one type of prosthesis. There was no significant difference between the two groups in operating time or total blood loss but postoperative pain was less in the patients in whom a tourniquet had not been used. They achieved straight-leg raising and knee flexion earlier and had fewer
Techniques for fixation of fractures of the lateral
malleolus have remained essentially unchanged since the 1960s, but
are associated with complication rates of up to 30%. The fibular
nail is an alternative method of fixation requiring a minimal incision
and tissue dissection, and has the potential to reduce the incidence
of complications. We reviewed the results of 105 patients with unstable fractures
of the ankle that were fixed between 2002 and 2010 using the Acumed
fibular nail. The mean age of the patients was 64.8 years (22 to
95), and 80 (76%) had significant systemic medical comorbidities.
Various different configurations of locking screw were assessed
over the study period as experience was gained with the device.
Nailing without the use of locking screws gave satisfactory stability
in only 66% of cases (4 of 6). Initial locking screw constructs
rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable.
Overall, seven patients had loss of fixation of the fracture and
there were five post-operative wound infections related to the distal
fibula. This lead to the development of the current technique with
a screw across the syndesmosis in addition to a distal locking screw.
In 21 patients treated with this technique there have been no significant
complications and only one
Between December 2004 and June 2006, 136 patients (156 total hip replacements), were sent from the waiting list of the Cardiff Vale NHS Trust to the NHS Treatment Centre, Weston-super-Mare, in an attempt to reduce the waiting time for total hip replacement. Because of concerns about their outcome, each patient was contacted and invited to attend a review appointment with a consultant specialising in hip and revision hip replacement. A total of 98 patients (113 hips) were reviewed after a mean of 23 months (11 to 30). There were 104 cemented hips, seven hybrid and two cementless. An acetabular inclination of >
55° was seen in 18 (16%). Radiolucent lines around the acetabular component were seen in 76 (67%). The femoral component was in more than 4° of varus in 47 (42%). The medial floor had been breached in 13 (12%) and there was a leg-length discrepancy of more than 1 cm in ten (9%). There were three dislocations, one femoral fracture, one pulmonary embolus, one deep infection and two
We review the results of a modified quadricepsplasty in five children who developed stiffness of the knee after femoral lengthening for congenital short femur using an Ilizarov external fixator which spanned the knee. All had a full range of movement of the knee before lengthening was undertaken. Unifocal lengthening was carried out in the distal metaphysiodiaphyseal region of the distal femur with a mean gain of 6.5 cm. The mean percentage lengthening was 24%. At the end of one year after removal of the Ilizarov frame and despite intensive physiotherapy all patients had stiffness. Physiotherapy was continued after the quadricepsplasty and, at the latest follow-up (mean 27 months), the mean active flexion was 102° (80 to 130). The gain in movement ranged from 50° to 100°. One patient had a
Between 1988 and 1995, we studied 91 club feet from a series of 120 recalcitrant feet in 86 patients requiring surgical treatment. There were 48 boys and 20 girls. The mean age at operation was 8.9 months. Surgery consisted of an initial plantar medial release followed two weeks later by a posterolateral release. This strategy was adopted specifically to address the problems of wound healing associated with single-stage surgery and to ascertain the rate of relapse after a two-stage procedure. Immobilisation in plaster was used for three months followed by night splintage. The feet were classified preoperatively and prospectively into four grades according to the system suggested by Dimeglio et al. Grade-1 feet were postural and did not require surgery. All wounds were closed primarily. One
The aim of this study was to evaluate whether, after correction of an adolescent idiopathic scoliosis (AIS), leaving out the subfascial drain gives results that are no worse than using a drain in terms of total blood loss, drop in haemoglobin level, and opioid consumption. Adolescents (aged between 10 and 21 years) with an idiopathic scoliosis (major curve ≥ 45°) were eligible for inclusion in this randomized controlled noninferiority trial (n = 125). A total of 90 adolescents who had undergone segmental pedicle screw instrumentation were randomized into no-drain or drain groups at the time of wound closure using the sealed envelope technique (1:1). The primary outcome was a drop in the haemoglobin level during first three postoperative days. Secondary outcomes were 48-hour postoperative oxycodone consumption and surgical complications.Aims

The aim was to assess whether robotic-assisted total knee arthroplasty (rTKA) had greater knee-specific outcomes, improved fulfilment of expectations, health-related quality of life (HRQoL), and patient satisfaction when compared with manual TKA (mTKA). A randomized controlled trial was undertaken (May 2019 to December 2021), and patients were allocated to either mTKA or rTKA. A total of 100 patients were randomized, 50 to each group, of whom 43 rTKA and 38 mTKA patients were available for review at 12 months following surgery. There were no statistically significant preoperative differences between the groups. The minimal clinically important difference in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score was defined as 7.5 points.Aims
Methods
The primary aim was to assess whether robotic total knee arthroplasty (rTKA) had a greater early knee-specific outcome when compared to manual TKA (mTKA). Secondary aims were to assess whether rTKA was associated with improved expectation fulfilment, health-related quality of life (HRQoL), and patient satisfaction when compared to mTKA. A randomized controlled trial was undertaken, and patients were randomized to either mTKA or rTKA. The primary objective was functional improvement at six months. Overall, 100 patients were randomized, 50 to each group, of whom 46 rTKA and 41 mTKA patients were available for review at six months following surgery. There were no differences between the two groups.Aims

Septic arthritis of the hip often leads to irreversible osteoarthritis (OA) and the requirement for total hip arthroplasty (THA). The aim of this study was to report the mid-term risk of any infection, periprosthetic joint infection (PJI), aseptic revision, and reoperation in patients with a past history of septic arthritis who underwent THA, compared with a control group of patients who underwent THA for OA. We retrospectively identified 256 THAs in 244 patients following septic arthritis of the native hip, which were undertaken between 1969 and 2016 at a single institution. Each case was matched 1:1, based on age, sex, BMI, and year of surgery, to a primary THA performed for OA. The mean age and BMI were 58 years (35 to 84) and 31 kg/m2 (18 to 48), respectively, and 100 (39%) were female. The mean follow-up was 11 years (2 to 39).Aims
Methods
Contemporary outcomes of primary total hip arthroplasties (THAs) with highly cross-linked polyethylene (HXLPE) liners in patients with inflammatory arthritis have not been well studied. This study examined the implant survivorship, complications, radiological results, and clinical outcomes of THA in patients with inflammatory arthritis. We identified 418 hips (350 patients) with a primary diagnosis of inflammatory arthritis who underwent primary THA with HXLPE liners from January 2000 to December 2017. Of these hips, 68% had rheumatoid arthritis (n = 286), 13% ankylosing spondylitis (n = 53), 7% juvenile rheumatoid arthritis (n = 29), 6% psoriatic arthritis (n = 24), 5% systemic lupus erythematosus (n = 23), and 1% scleroderma (n = 3). Mean age was 58 years (SD 14.8), 66.3% were female (n = 277), and mean BMI was 29 kg/m2 (SD 7). Uncemented femoral components were used in 77% of cases (n = 320). Uncemented acetabular components were used in all patients. Competing risk analysis was used accounting for death. Mean follow-up was 4.5 years (2 to 18).Aims
Methods
The number of revision arthroplasties being performed in the elderly is expected to rise, including revision for infection. The primary aim of this study was to measure the treatment success rate for octogenarians undergoing revision total hip arthroplasty (THA) for periprosthetic joint infection (PJI) compared to a younger cohort. Secondary outcomes were complications and mortality. Patients undergoing one- or two-stage revision of a primary THA for PJI between January 2008 and January 2021 were identified. Age, sex, BMI, American Society of Anesthesiologists grade, Charlson Comorbidity Index (CCI), McPherson systemic host grade, and causative organism were collated for all patients. PJI was classified as ‘confirmed’, ‘likely’, or ‘unlikely’ according to the 2021 European Bone and Joint Infection Society criteria. Primary outcomes were complications, reoperation, re-revision, and successful treatment of PJI. A total of 37 patients aged 80 years or older and 120 patients aged under 80 years were identified. The octogenarian group had a significantly lower BMI and significantly higher CCI and McPherson systemic host grades compared to the younger cohort.Aims

Nonagenarians (aged 90 to 99 years) have experienced the fastest percent decile population growth in the USA recently, with a consequent increase in the prevalence of nonagenarians living with joint arthroplasties. As such, the number of revision total hip arthroplasties (THAs) and total knee arthroplasties (TKAs) in nonagenarians is expected to increase. We aimed to determine the mortality rate, implant survivorship, and complications of nonagenarians undergoing aseptic revision THAs and revision TKAs. Our institutional total joint registry was used to identify 96 nonagenarians who underwent 97 aseptic revisions (78 hips and 19 knees) between 1997 and 2018. The most common indications were aseptic loosening and periprosthetic fracture for both revision THAs and revision TKAs. Mean age at revision was 92 years (90 to 98), mean BMI was 27 kg/m2 (16 to 47), and 67% (n = 65) were female. Mean time between primary and revision was 18 years (SD 9). Kaplan-Meier survival was used for patient mortality, and compared to age- and sex-matched control populations. Reoperation risk was assessed using cumulative incidence with death as a competing risk. Mean follow-up was five years.Aims
Methods
Periacetabular osteotomy (PAO) is the preferred treatment for symptomatic acetabular dysplasia in adolescents and young adults. There remains a lack of consensus regarding whether intra-articular procedures such as labral repair or improvement of femoral offset should be performed at the time of PAO or addressed subsequent to PAO if symptoms warrant. The purpose was to determine the rate of subsequent hip arthroscopy (HA) in a contemporary cohort of patients, who underwent PAO in isolation without any intra-articular procedures. From June 2012 to March 2022, 349 rectus-sparing PAOs were performed and followed for a minimum of one year (mean 6.2 years (1 to 11)). The mean age was 24 years (14 to 46) and 88.8% were female (n = 310). Patients were evaluated at final follow-up for patient-reported outcome measures (PROMs). Clinical records were reviewed for complications or subsequent surgery. Radiographs were reviewed for the following acetabular parameters: lateral centre-edge angle, anterior centre-edge angle, acetabular index, and the alpha-angle (AA). Patients were cross-referenced from the two largest hospital systems in our area to determine if subsequent HA was performed. Descriptive statistics were used to analyze risk factors for HA.Aims
Methods
Periacetabular osteotomy (PAO) is widely recognized as a demanding surgical procedure for acetabular reorientation. Reports about the learning curve have primarily focused on complication rates during the initial learning phase. Therefore, our aim was to assess the PAO learning curve from an analytical perspective by determining the number of PAOs required for the duration of surgery to plateau and the accuracy to improve. The study included 118 consecutive PAOs in 106 patients. Of these, 28 were male (23.7%) and 90 were female (76.3%). The primary endpoint was surgical time. Secondary outcome measures included radiological parameters. Cumulative summation analysis was used to determine changes in surgical duration. A multivariate linear regression model was used to identify independent factors influencing surgical time.Aims

The aim of this study was to compare outcomes after growth-friendly treatment for early-onset scoliosis (EOS) between patients with skeletal dysplasias versus those with other syndromes. We retrospectively identified 20 patients with skeletal dysplasias and 292 with other syndromes (control group) who had completed surgical growth-friendly EOS treatment between 1 January 2000 and 31 December 2018. We compared radiological parameters, complications, and health-related quality of life (HRQoL) at mean follow-up of 8.6 years (SD 3.3) in the dysplasia group and 6.6 years (SD 2.6) in the control group.Aims
Methods
In cases of severe periprosthetic joint infection (PJI) of the knee, salvage procedures such as knee arthrodesis (KA) or above-knee amputation (AKA) must be considered. As both treatments result in limitations in quality of life (QoL), we aimed to compare outcomes and factors influencing complication rates, mortality, and mobility. Patients with PJI of the knee and subsequent KA or AKA between June 2011 and May 2021 were included. Demographic data, comorbidities, and patient history were analyzed. Functional outcomes and QoL were prospectively assessed in both groups with additional treatment-specific scores after AKA. Outcomes, complications, and mortality were evaluated.Aims
Methods
To assess the feasibility of a randomized controlled trial (RCT) that compares three treatments for acetabular fractures in older patients: surgical fixation, surgical fixation and hip arthroplasty (fix-and-replace), and non-surgical treatment. Patients were recruited from seven UK NHS centres and randomized to a three-arm pilot trial if aged older than 60 years and had a displaced acetabular fracture. Feasibility outcomes included patients’ willingness to participate, clinicians’ capability to recruit, and dropout rates. The primary clinical outcome measure was the EuroQol five-dimension questionnaire (EQ-5D) at six months. Secondary outcomes were Oxford Hip Score, Disability Rating Index, blood loss, and radiological and mobility assessments.Aims
Methods
The open Latarjet procedure is a widely used treatment for recurrent anterior instability of the shoulder. Although satisfactory outcomes are reported, factors which influence a patient’s experience are poorly quantified. The aim of this study was to evaluate the effect of a range of demographic factors and measures of the severity of instability on patient-reported outcome measures in patients who underwent an open Latarjet procedure at a minimum follow-up of two years. A total of 350 patients with anterior instability of the shoulder who underwent an open Latarjet procedure between 2005 and 2018 were reviewed prospectively, with the collection of demographic and psychosocial data, preoperative CT, and complications during follow-up of two years. The primary outcome measure was the Western Ontario Shoulder Instability Index (WOSI), assessed preoperatively, at two years postoperatively, and at mid-term follow-up at a mean of 50.6 months (SD 24.8) postoperatively. The secondary outcome measure was the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score. The influence of the demographic details of the patients, measurements of the severity of instability, and the complications of surgery were assessed in a multivariate analysis.Aims
Methods
Although absorbable sutures for the repair of acute Achilles tendon rupture (ATR) have been attracting attention, the rationale for their use remains insufficient. This study prospectively compared the outcomes of absorbable and nonabsorbable sutures for the repair of acute ATR. A total of 40 patients were randomly assigned to either braided absorbable polyglactin suture or braided nonabsorbable polyethylene terephthalate suture groups. ATR was then repaired using the Krackow suture method. At three and six months after surgery, the isokinetic muscle strength of ankle plantar flexion was measured using a computer-based Cybex dynamometer. At six and 12 months after surgery, patient-reported outcomes were measured using the Achilles tendon Total Rupture Score (ATRS), visual analogue scale for pain (VAS pain), and EuroQoL five-dimension health questionnaire (EQ-5D).Aims

The aim of this prospective study was to assess the long-term clinical, radiological, functional, and quality of life (QoL)-related outcome of patients treated with the synthetic Ligament Advanced Reinforcement System (LARS) device for anterior cruciate ligament (ACL) rupture. A total of 41 patients who underwent ACL reconstruction with the LARS device (mean age 39.8 years (SD 12.1 ); 32% females (n = 13)) were prospectively included between August 2001 and March 2005. MRI scans and radiographs were performed at a median follow-up of 2.0 years (interquartile range (IQR) 1.3 to 3.0; n = 40) and 12.8 years (IQR 12.1 to 13.8; n = 22). Functional and QoL-related outcome was assessed in 29 patients at a median follow-up of 12.8 years (IQR 12.0 to 14.0) and clinically reconfirmed at latest median follow-up of 16.5 years (IQR 15.5 to 17.9). International Knee Documentation Committee (IKDC) and Tegner scores were obtained pre- and postoperatively, and Lysholm score postoperatively only. At latest follow-up, range of motion, knee stability tests, 36-Item Short Form Health Survey (SF-36), and IKDC scores were ascertained. Complications and reoperations during follow-up were documented.Aims

The purpose of this study was to compare clinical results, long-term survival, and complication rates of stemless shoulder prosthesis with stemmed anatomical shoulder prostheses for treatment of osteoarthritis and to analyze radiological bone changes around the implants during follow-up. A total of 161 patients treated with either a stemmed or a stemless shoulder arthroplasty for primary osteoarthritis of the shoulder were evaluated with a mean follow-up of 118 months (102 to 158). The Constant score (CS), the Disabilities of the Arm, Shoulder and Hand (DASH) score, and active range of motion (ROM) were recorded. Radiological analysis for bone adaptations was performed by plain radiographs. A Kaplan-Meier survivorship analysis was calculated and complications were noted.Aims

We aimed to compare the implant survival, complications, readmissions, and mortality of Vancouver B2 periprosthetic femoral fractures (PFFs) treated with internal fixation with that of B1 PFFs treated with internal fixation and B2 fractures treated with revision arthroplasty. We retrospectively reviewed the data of 112 PFFs, of which 47 (42%) B1 and 27 (24%) B2 PFFs were treated with internal fixation, whereas 38 (34%) B2 fractures underwent revision arthroplasty. Decision to perform internal fixation for B2 PFFs was based on specific radiological (polished femoral components, intact bone-cement interface) and clinical criteria (low-demand patient). Median follow-up was 36.4 months (24 to 60). Implant survival and mortality over time were estimated with the Kaplan-Meier method. Adverse events (measured with a modified Dindo-Clavien classification) and 90-day readmissions were additionally compared between groups.Aims
Methods
To determine the relationship between articular cartilage status and clinical outcomes after medial opening-wedge high tibial osteotomy (MOHTO) for medial compartmental knee osteoarthritis at intermediate follow-up. We reviewed 155 patients (155 knees) who underwent MOHTO from January 2008 to December 2016 followed by second-look arthroscopy with a mean 5.3-year follow-up (2.0 to 11.7). Arthroscopic findings were assessed according to the International Cartilage Repair Society (ICRS) Cartilage Repair Assessment (CRA) grading system. Patients were divided into two groups based on the presence of normal or nearly normal quality cartilage in the medial femoral condyle: good (second-look arthroscopic) status (ICRS grade I or II; n = 70), and poor (second-look arthroscopic) status (ICRS grade III or IV; n = 85) groups at the time of second-look arthroscopy. Clinical outcomes were assessed using the International Knee Documentation Committee (IKDC) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and 36-Item Short Form survey.Aims
Methods
The direct anterior approach (DAA) for total hip arthroplasty (THA) has potential advantages over other approaches and is most commonly performed with the patient in the supine position. We describe a technique for DAA THA with the patient in the lateral decubitus position and report the early clinical and radiological outcomes, the characteristics of the learning curve, and perioperative complications. All primary DAA THAs performed in the lateral position by a single surgeon over a four-year period from the surgeon’s first case using the technique were identified from a prospectively collected database. Modified Harris Hip Scores (mHHS) were collected to assess clinical outcome, and routine radiological analysis was performed. Retrospective review of the medical records identified perioperative complications, the characteristics of the learning curve, and revisions.Aims
Methods
The prevalence of ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) is rising in concert with life expectancy, putting more patients at risk for interprosthetic femur fractures (IPFFs). Our study aimed to assess treatment methodologies, implant survivorship, and IPFF clinical outcomes. A total of 76 patients treated for an IPFF from February 1985 to April 2018 were reviewed. Prior to fracture, at the hip/knee sites respectively, 46 femora had primary/primary, 21 had revision/primary, three had primary/revision, and six had revision/revision components. Mean age and BMI were 74 years (33 to 99) and 30 kg/m2 (21 to 46), respectively. Mean follow-up after fracture treatment was seven years (2 to 24).Aims
Methods
We studied the safety and efficacy of multimodal thromboprophylaxis in patients with a history of venous thromboembolism (VTE) who undergo total hip arthroplasty (THA) within the first 120 postoperative days, and the mortality during the first year. Multimodal prophylaxis includes discontinuation of procoagulant medications, VTE risk stratification, regional anaesthesia, an intravenous bolus of unfractionated heparin prior to femoral preparation, rapid mobilization, the use of pneumatic compression devices, and chemoprophylaxis tailored to the patient’s risk of VTE. Between 2004 to 2018, 257 patients with a proven history of VTE underwent 277 primary elective THA procedures by two surgeons at a single institution. The patients had a history of deep vein thrombosis (DVT) (186, 67%), pulmonary embolism (PE) (43, 15.5%), or both (48, 17.5%). Chemoprophylaxis included aspirin (38 patients), anticoagulation (215 patients), or a combination of aspirin and anticoagulation (24 patients). A total of 50 patients (18%) had a vena cava filter in situ at the time of surgery. Patients were followed for 120 days to record complications, and for one year to record mortality.Aims
Methods
The results of surgery for Dupuytren’s disease can be compromised by the potential for disease recurrence and loss of function. Selecting which patients will benefit from repeat surgery, when to operate, and what procedure to undertake requires judgement and an understanding of patient expectations and functional needs. We undertook this study to investigate patient outcomes and satisfaction following repeat limited fasciectomy for recurrent Dupuytren’s disease. We prospectively identified all patients presenting with recurrence of Dupuytren’s disease who were selected for surgical treatment with repeat limited fasciectomy surgery between January 2013 and February 2015. Patients were assessed preoperatively, and again at a minimum of five years postoperatively. We identified 43 patients who were carefully selected for repeat fasciectomy involving 54 fingers. Patients with severe or aggressive disease with extensive skin involvement were not included; in our practice, these patients are instead counselled and preferentially treated with dermofasciectomy. The primary outcome measured was change in the Michigan Hand Outcomes Questionnaire (MHQ) score. Secondary outcomes were change in finger range of motion, flexion contracture, Semmes-Weinstein monofilament (SWM) values, and overall satisfaction.Aims
Methods
To report the surgical outcome of patients with severe Scheuermann’s kyphosis treated using a consistent technique and perioperative management. We reviewed 88 consecutive patients with a severe Scheuermann's kyphosis who had undergone posterior spinal fusion with closing wedge osteotomies and hybrid instrumentation. There were 55 males and 33 females with a mean age of 15.9 years (12.0 to 24.7) at the time of surgery. We recorded their demographics, spinopelvic parameters, surgical correction, and perioperative data, and assessed the impact of surgical complications on outcome using the Scoliosis Research Society (SRS)-22 questionnaire.Aims
Methods
Tranexamic acid (TXA) has been shown to reduce blood loss and transfusion requirements in patients undergoing orthopaedic surgery. There remains a lack of prospective evidence for the use of TXA in patients undergoing periacetabular osteotomy (PAO). The purpose of this study was to determine if intravenous (IV) TXA is effective in reducing calculated blood loss and transfusions after PAO. This was a single-centre prospective double-blind placebo-controlled randomized trial of 81 patients aged 12 to 45 years undergoing elective PAO by a single surgeon. The intervention group (n = 40) received two doses of IV TXA of a maximum 1 g in each dose; the control group (n = 41) received two doses of 50 ml 0.9% saline IV. The primary outcome was perioperative calculated blood loss. Secondary outcomes included allogenic transfusions and six-week postoperative complications.Aims
Methods
Infection after surgery increases treatment costs and is associated with increased mortality. Hip fracture patients have historically had high rates of methicillin-resistant A total of 13,503 patients who presented with a hip fracture over 17 years formed the study population. Multivariable logistic regression was performed to determine risk factors for MRSA and SSI. Autoregressive integrated moving average (ARIMA) modelling adjusted for temporal trends in rates of MRSA. Kaplan-Meier estimators were generated to assess for changes in mortality.Aims
Methods
Spinal fusion remains the gold standard in the treatment of idiopathic scoliosis. However, anterior vertebral body tethering (AVBT) is gaining widespread interest, despite the limited data on its efficacy. The aim of our study was to determine the clinical efficacy of AVBT in skeletally immature patients with idiopathic scoliosis. All consecutive skeletally immature patients with idiopathic scoliosis treated with AVBT enrolled in a longitudinal, multicentre, prospective database between 2013 and 2016 were analyzed. All patients were treated by one of two surgeons working at two independent centres. Data were collected prospectively in a multicentre database and supplemented retrospectively where necessary. Patients with a minimum follow-up of two years were included in the analysis. Clinical success was set a priori as a major coronal Cobb angle of < 35° at the most recent follow-up.Aims
Methods
Preoperative talar valgus deformity ≥ 15° is considered a contraindication for total ankle arthroplasty (TAA). We compared operative procedures and clinical outcomes of TAA in patients with talar valgus deformity ≥ 15° and < 15°. A matched cohort of patients similar for demographics and components used but differing in preoperative coronal-plane tibiotalar valgus deformity ≥ 15° (valgus, n = 50; 52% male, mean age 65.8 years (SD 10.3), mean body mass index (BMI) 29.4 (SD 5.2)) or < 15° (control, n = 50; 58% male, mean age 65.6 years (SD 9.8), mean BMI 28.7 (SD 4.2)), underwent TAA by one surgeon. Preoperative and postoperative radiographs, Ankle Osteoarthritis Scale (AOS) pain and disability and 36-item Short Form Health Survey (SF-36) version 2 scores were collected prospectively. Ancillary procedures, secondary procedures, and complications were recorded.Aims
Methods
The primary aim of this study was to describe patient satisfaction and health-related quality of life (HRQoL) following corrective osteotomy for a symptomatic malunion of the distal radius. We retrospectively identified 122 adult patients from a single centre over an eight-year period who had undergone corrective osteotomy for a symptomatic malunion of the distal radius. The primary long-term outcome was the Patient-Rated Wrist Evaluation (PRWE) score. Secondary outcomes included the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, the EQ-5D-5L score, complications, and the Net Promoter Score (NPS). Multivariate regression analysis was used to determine factors associated with the PRWE score.Aims
Methods
Previous research has demonstrated increased early complication rates following total hip arthroplasty (THA) in obese patients, as defined by body mass index (BMI). Subcutaneous fat depth (FD) has been shown to be an independent risk factor for wound infection in cervical and lumbar spine surgery, as well as after abdominal laparotomy. The aim of this study was to investigate whether increased peritrochanteric FD was associated with an increased risk of complications in the first year following THA. We analyzed prospectively collected data on a consecutive series of 1,220 primary THAs from June 2013 until May 2018. The vertical soft tissue depth from the most prominent part of the greater trochanter to the skin was measured intraoperatively using a sterile ruler and recorded to the nearest millimetre. BMI was calculated at the patient’s preoperative assessment. All surgical complications occuring within the initial 12 months of follow-up were identified.Aims
Methods
The aim of this study was to investigate whether the use of antibiotic-loaded bone cement influenced the risk of revision surgery after primary total hip arthroplasty (THA) for osteoarthritis. The study involved data collected by the National Joint Registry (NJR) for England and Wales, Northern Ireland and the Isle of Man between 1 September 2005 and 31 August 2017. Cox proportional hazards were used to investigate the association between use of antibiotic-loaded bone cement and the risk of revision due to prosthetic joint infection (PJI), with adjustments made for the year of the initial procedure, age at the time of surgery, sex, American Society of Anesthesiologists (ASA) grade, head size, and body mass index (BMI). We looked also at the association between use of antibiotic-loaded bone cement and the risk of revision due to aseptic loosening or osteolysis.Aims
Methods
Rates of readmission and reoperation following primary total knee arthroplasty (TKA) are under scrutiny due to new payment models, which penalize these negative outcomes. Some risk factors are more modifiable than others, and some conditions considered modifiable such as obesity may not be as modifiable in the setting of advanced arthritis as many propose. We sought to determine whether controlling for hypoalbuminaemia would mitigate the effect that prior authors had identified in patients with obesity. We reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for the period of January 2008 to December 2016 to evaluate the rates of reoperation and readmission within 30 days following primary TKA. Multivariate logistic regression modelling controlled for preoperative albumin, age, sex, and comorbidity status.Aims
Methods
Two-stage exchange arthroplasty is the most common definitive treatment for prosthetic joint infection (PJI) in the USA. Complications that occur during treatment are often not considered. The purpose of this study was to analyze complications in patients undergoing two-stage exchange for infected total knee arthroplasty (TKA) and determine when they occur. We analyzed all patients that underwent two-stage exchange arthroplasty for treatment of PJI of the knee from January 2010 to December 2018 at a single institution. We categorized complications as medical versus surgical. The intervals for complications were divided into: interstage; early post-reimplantation (three months); and late post-reimplantation (three months to minimum one year). Minimum follow-up was one year. In total, 134 patients underwent a first stage of a two-stage exchange. There were 69 males and 65 females with an mean age at first stage surgery of 67 years (37 to 89). Success was based on the new Musculoskeletal Infection Society (MSIS) definition of success reporting.Aims
Methods
While patients with psychological distress have poorer short-term outcomes after total knee arthroplasty (TKA), their longer-term function is unknown. We aimed to 1) assess the influence of preoperative mental health status on long-term functional outcomes, quality of life, and patient satisfaction; and 2) analyze the change in mental health after TKA, in a cohort of patients with no history of mental health disorder, with a minimum of ten years’ follow-up. Prospectively collected data of 122 patients undergoing primary unilateral TKA in 2006 were reviewed. Patients were assessed pre- and postoperatively at two and ten years using the Knee Society Knee Score (KSKS) and Function Score (KSFS); Oxford Knee Score (OKS); and the Mental (MCS) and Physical Component Summary (PCS) which were derived from the 36-Item Short-Form Health Survey questionnaire (SF-36). Patients were stratified into those with psychological distress (MCS < 50, n = 51) and those without (MCS ≥ 50, n = 71). Multiple regression was used to control for age, sex, BMI, Charlson Comorbidity Index (CCI), and baseline scores. The rate of expectation fulfilment and satisfaction was compared between patients with low and high MCS.Aims

Currently, periprosthetic fractures are excluded from the American Society for Bone and Mineral Research (ASBMR) definition of atypical femoral fracture (AFFs). This study aims to report on a series of periprosthetic femoral fractures (PFFs) that otherwise meet the criteria for AFFs. Secondary aims were to identify predictors of periprosthetic atypical femoral fractures (PAFFs) and quantify the complications of treatment. This was a retrospective case control study of consecutive patients with periprosthetic femoral fractures between 2007 and 2017. Two observers identified 16 PAFF cases (mean age 73.9 years (44 to 88), 14 female patients) and 17 typical periprosthetic fractures in patients on bisphosphonate therapy as controls (mean age 80.7 years (60 to 86, 13 female patients). Univariate and multivariate analysis was performed to identify predictors of PAFF. Management and complications were recorded.Aims
Patients and Methods
Varus-valgus constrained (VVC) implants are often used during revision total knee arthroplasty (TKA) to gain coronal plane stability. However, the increased mechanical torque applied to the bone-cement interface theoretically increases the risk of aseptic loosening. We assessed mid-term survivorship, complications, and clinical outcomes of a fixed-bearing VVC device in revision TKAs. A total of 416 consecutive revision TKAs (398 patients) were performed at our institution using a single fixed-bearing VVC TKA from 2007 to 2015. Mean age was 64 years (33 to 88) with 50% male (199). Index revision TKA diagnoses were: instability (n = 122, 29%), aseptic loosening (n = 105, 25%), and prosthetic joint infection (PJI) (n = 97, 23%). All devices were cemented on the epiphyseal surfaces. Femoral stems were used in 97% (n = 402) of cases, tibial stems in 95% (n = 394) of cases; all were cemented. In total, 93% (n = 389) of cases required a stemmed femoral and tibial component. Femoral cones were used in 29%, and tibial cones in 40%. Survivorship was assessed via competing risk analysis; clinical outcomes were determined using Knee Society Scores (KSSs) and range of movement (ROM). Mean follow-up was four years (2 to 10).Aims
Methods
There has been a significant reduction in unicompartmental knee arthroplasty (UKA) procedures recorded in Australia. This follows several national joint registry studies documenting high UKA revision rates when compared to total knee arthroplasty (TKA). With the recent introduction of robotically assisted UKA procedures, it is hoped that outcomes improve. This study examines the cumulative revision rate of UKA procedures implanted with a newly introduced robotic system and compares the results to one of the best performing non-robotically assisted UKA prostheses, as well as all other non-robotically assisted UKA procedures. Data from the Australian Orthopaedic Association National Joint Arthroplasty Registry (AOANJRR) for all UKA procedures performed for osteoarthritis (OA) between 2015 and 2018 were analyzed. Procedures using the Restoris MCK UKA prosthesis implanted using the Mako Robotic-Arm Assisted System were compared to non-robotically assisted Zimmer Unicompartmental High Flex Knee System (ZUK) UKA, a commonly used UKA with previously reported good outcomes and to all other non-robotically assisted UKA procedures using Cox proportional hazard ratios (HRs) and Kaplan-Meier estimates of survivorship.Aim

Debate continues about whether it is better to use a cemented or uncemented hemiarthroplasty to treat a displaced intracapsular fracture of the hip. The aim of this study was to attempt to resolve this issue for contemporary prostheses. A total of 400 patients with a displaced intracapsular fracture of the hip were randomized to receive either a cemented polished tapered stem hemiarthroplasty or an uncemented Furlong hydroxyapatite-coated hemiarthroplasty. Follow-up was conducted by a nurse blinded to the implant at set intervals for up to one year from surgery.Aims

The aim of this study was to report our experience at 3.5 years with outpatient total hip arthroplasty (THA). In this prospective cohort study, we included all patients who were planned to receive primary THA through the anterior approach between 1 April 2014 and 1 October 2017. Patient-related data and surgical information were recorded. Patient reported outcome measures (PROMs) related to the hip and an anchor question were taken preoperatively, at six weeks, three months, and one year after surgery. All complications, readmissions, and reoperations were registered.Aims

The aim of this study was to compare the surgical and quality-of-life outcomes of children with skeletal dysplasia to those in children with idiopathic early-onset scoliosis (EOS) undergoing growth-friendly management. A retrospective review of two prospective multicentre EOS databases identified 33 children with skeletal dysplasia and EOS (major curve ≥ 30°) who were treated with growth-friendly instrumentation at younger than ten years of age, had a minimum two years of postoperative follow-up, and had undergone three or more lengthening procedures. From the same registries, 33 matched controls with idiopathic EOS were identified. A total of 20 children in both groups were treated with growing rods and 13 children were treated with vertical expandable prosthetic titanium rib (VEPTR) instrumentation.Aims
Patients and Methods
The aim of this study was to assess the influence of obesity on the clinical outcomes and survivorship ten years postoperatively in patients who underwent a fixed-bearing unicompartmental knee arthroplasty (UKA). We prospectively followed 184 patients who underwent UKA between 2003 and 2007 for a minimum of ten years. A total of 142 patients with preoperative body mass index (BMI) of < 30 kg/m2 were in the control group (32 male, 110 female) and 42 patients with BMI of ≥ 30 kg/m2 were in the obese group (five male, 37 female). Pre- and postoperative range of movement (ROM), Knee Society Score (KSS), Oxford Knee Score (OKS), 36-Item Short-Form Health Survey (SF-36), and survivorship were analyzed.Aims
Patients and Methods
There is little information regarding the risk of a patient developing prosthetic joint infection (PJI) after primary total knee arthroplasty (TKA) when the patient has previously experienced PJI of a TKA or total hip arthroplasty (THA) in another joint. The goal of this study was to compare the risk of PJI of primary TKA in this patient population against matched controls. We retrospectively reviewed 95 patients (102 primary TKAs) treated between 2000 and 2014 with a history of PJI in another TKA or THA. A total of 50 patients (53%) were female. Mean age was 69 years (45 to 88) with a mean body mass index (BMI) of 36 kg/m2 (22 to 59). In total, 27% of patients were on chronic antibiotic suppression. Mean follow-up was six years (2 to 16). We 1:3 matched these (for age, sex, BMI, and surgical year) to 306 primary TKAs performed in 306 patients with a THA or TKA of another joint without a subsequent PJI. Competing risk with death was used for statistical analysis. Multivariate analysis was followed to evaluate risk factors for PJI in the study cohort.Aims
Patients and Methods
The aim of this study was to determine whether the sequential
application of povidone iodine-alcohol (PVI) followed by chlorhexidine
gluconate-alcohol (CHG) would reduce surgical wound contamination
to a greater extent than PVI applied twice in patients undergoing
spinal surgery. A single-centre, interventional, two arm, parallel group randomised
controlled trial was undertaken, involving 407 patients who underwent
elective spinal surgery. For 203 patients, the skin was disinfected before surgery using
PVI (10% [w/w (1% w/w available iodine)] in 95% industrial denatured
alcohol, povidone iodine; Videne Alcoholic Tincture) twice, and
for 204 patients using PVI once followed by CHG (2% [w/v] chlorhexidine
gluconate in 70% [v/v] isopropyl alcohol; Chloraprep with tint).
The primary outcome measure was contamination of the wound determined
by aerobic and anaerobic bacterial growth from samples taken after
disinfection.Aims

The aim of this study was to evaluate health-related quality of life (HRQoL) and joint function in tenosynovial giant cell tumour (TGCT) patients before and after surgical treatment. This prospective cohort study run in two Dutch referral centres assessed patient-reported outcome measures (PROMs; 36-Item Short-Form Health Survey (SF-36), visual analogue scale (VAS) for pain, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)) in 359 consecutive patients with localized- and diffuse-type TGCT of large joints. Patients with recurrent disease (n = 121) and a wait-and-see policy (n = 32) were excluded. Collected data were analyzed at specified time intervals preoperatively (baseline) and/or postoperatively up to five years.Aims
Patients and Methods
This study compared multiple sclerosis (MS) patients who underwent
primary total hip arthroplasty (THA) with a matched cohort. Specifically,
we evaluated: 1) implant survivorship; 2) functional outcomes (modified
Harris Hip Scores (mHHS), Hip Disability and Osteoarthritis Outcome
Score, Joint Replacement (HOOS JR), and modified Multiple Sclerosis
Impact Scale (mMSIS) scores (with the MS cohort also evaluated based
on the disease phenotype)); 3) physical therapy duration and return
to function; 4) radiographic outcomes; and 5) complications. We reviewed our institution’s database to identify MS patients
who underwent THA between January 2008 and June 2016. A total of
34 MS patients (41 hips) were matched in a 1:2 ratio to a cohort
of THA patients who did not have MS, based on age, body mass index
(BMI), and Charlson/Deyo score. Patient records were reviewed for complications,
and their functional outcomes and radiographs were reviewed at their
most recent follow-up.Aims
Patients and Methods
This study investigated the influence of body mass index (BMI)
on patients’ function and quality of life ten years after total
knee arthroplasty (TKA). A total of 126 patients who underwent unilateral TKA in 2006
were prospectively included in this retrospective study. They were
categorized into two groups based on BMI: < 30 kg/m2 (control)
and ≥ 30 kg/m2 (obese). Functional outcome was assessed
using the Knee Society Function Score (KSFS), Knee Society Knee
Score (KSKS), and Oxford Knee Score (OKS). Quality of life was assessed
using the Physical (PCS) and Mental Component Scores (MCS) of the 36-Item
Short-Form Health Survey.Aims

The aim of this study was to compare the effectiveness of a femoral
nerve block and a periarticular infiltration in the management of
early post-operative pain after total knee arthroplasty (TKA). A pragmatic, single centre, two arm parallel group, patient blinded,
randomised controlled trial was undertaken. All patients due for
TKA were eligible. Exclusion criteria included contraindications
to the medications involved in the study and patients with a neurological
abnormality of the lower limb. Patients received either a femoral
nerve block with 75 mg of 0.25% levobupivacaine hydrochloride around
the nerve, or periarticular infiltration with 150 mg of 0.25% levobupivacaine
hydrochloride, 10 mg morphine sulphate, 30 mg ketorolac trometamol
and 0.25 mg of adrenaline all diluted with 0.9% saline to make a
volume of 150 ml.Aims
Patients and Methods
Our aim was to determine whether, based on the current literature,
bariatric surgery prior to total hip (THA) or total knee arthroplasty
(TKA) reduces the complication rates and improves the outcome following
arthroplasty in obese patients. A systematic literature search was undertaken of published and
unpublished databases on the 5 November 2015. All papers reporting
studies comparing obese patients who had undergone bariatric surgery
prior to arthroplasty, or not, were included. Each study was assessed
using the Downs and Black appraisal tool. A meta-analysis of risk ratios
(RR) and 95% confidence intervals (CI) was performed to determine
the incidence of complications including wound infection, deep vein
thrombosis (DVT), pulmonary embolism (PE), revision surgery and
mortality.Aims
Methods
We undertook a prospective non-randomised radiological study
to evaluate the preliminary results of using magnetically-controlled
growing rods (MAGEC System, Ellipse technology) to treat children
with early-onset scoliosis. Between January 2011 and January 2015, 19 children were treated
with magnetically-controlled growing rods (MCGRs) and underwent
distraction at three-monthly intervals. The mean age of our cohort
was 9.1 years (4 to 14) and the mean follow-up 22.4 months (5.1
to 35.2). Of the 19 children, eight underwent conversion from traditional growing
rods. Whole spine radiographs were carried out pre- and post-operatively:
image intensification was used during each lengthening in the outpatient
department. The measurements evaluated were Cobb angle, thoracic kyphosis,
proximal junctional kyphosis and spinal growth from T1 to S1.Aims
Patients and Methods
To compare the outcomes for trochanteric fractures treated with
a sliding hip screw (SHS) or a cephalomedullary nail. A total of 400 patients with a trochanteric hip fracture were
randomised to receive a SHS or a cephalomedullary nail (Targon PFT).
All surviving patients were followed up to one year from injury.
Functional outcome was assessed by a research nurse blinded to the
implant used.Aims

We present the results of correcting a double or triple curve
adolescent idiopathic scoliosis using a convex segmental pedicle
screw technique. We reviewed 191 patients with a mean age at surgery of 15 years
(11 to 23.3). Pedicle screws were placed at the convexity of each
curve. Concave screws were inserted at one or two cephalad levels
and two caudal levels. The mean operating time was 183 minutes (132
to 276) and the mean blood loss 0.22% of the total blood volume
(0.08% to 0.4%). Multimodal monitoring remained stable throughout
the operation. The mean hospital stay was 6.8 days (5 to 15).Aims
Patients and Methods
The aim of this study was to evaluate the functional
and oncological outcome of extracorporeally irradiated autografts
used to reconstruct the pelvis after a P1/2 internal hemipelvectomy. The study included 18 patients with a primary malignant bone
tumour of the pelvis. There were 13 males and five females with
a mean age of 24.8 years (8 to 62). Of these, seven had an osteogenic
sarcoma, six a Ewing’s sarcoma, and five a chondrosarcoma. At a
mean follow-up of 51.6 months (4 to 185), nine patients had died
with metastatic disease while nine were free from disease. Local
recurrence occurred in three patients all of whom eventually died of
their disease. Deep infection occurred in three patients and required
removal of their graft in two while the third underwent a hindquarter
amputation for extensive flap necrosis. The mean Musculoskeletal Tumor Society functional score of the
16 patients who could be followed-up for at least 12 months was
77% (50 to 90). Those 15 patients who completed the Toronto Extremity
Salvage Score questionnaire had a mean score of 71% (53 to 85). Extracorporeal irradiation and re-implantation of bone is a valid
method of reconstruction after an internal hemipelvectomy. It has
an acceptable morbidity and a functional outcome that compares favourably
with other available reconstructive techniques. Cite this article:
Charcot neuro-osteoarthropathy (CN) of the midfoot
presents a major reconstructive challenge for the foot and ankle
surgeon. The Synthes 6 mm Midfoot Fusion Bolt is both designed and
recommended for patients who have a deformity of the medial column
of the foot due to CN. We present the results from the first nine
patients (ten feet) on which we attempted to perform fusion of the
medial column using this bolt. Six feet had concurrent hindfoot fusion
using a retrograde nail. Satisfactory correction of deformity of
the medial column was achieved in all patients. The mean correction
of calcaneal pitch was from 6°
(-15° to +18°) pre-operatively to 16° (7° to 23°) post-operatively;
the mean Meary angle from 26° (3° to 46°) to 1° (1° to 2°); and
the mean talometatarsal angle on dorsoplantar radiographs from 27°
(1° to 48°) to 1° (1° to 3°). However, in all but two feet, at least one joint failed to fuse.
The bolt migrated in six feet, all of which showed progressive radiographic
osteolysis, which was considered to indicate loosening. Four of
these feet have undergone a revision procedure, with good radiological
evidence of fusion. The medial column bolt provided satisfactory correction
of the deformity but failed to provide adequate fixation for fusion
in CN deformities in the foot. In its present form, we cannot recommend the routine use of this
bolt. Cite this article:
The aims of this study were to evaluate the clinical and radiological
outcomes of the Universal-2 total wrist arthroplasty (TWA) in patients
with rheumatoid arthritis. This was a retrospective review of all 95 Universal-2 TWAs which
were performed in our institution between 2003 to 2012 in patients
with rheumatoid arthritis. A total of six patients were lost to
follow-up and two died of unrelated causes. A total of ten patients
had bilateral procedures. Accordingly, 75 patients (85 TWAs) were
included in the study. There were 59 women and 16 men with a mean
age of 59 years (26 to 86). The mean follow-up was 53 months (24
to 120). Clinical assessment involved recording pain on a visual
analogue score, range of movement, grip strength, the Quick Disabilities
of the Arm, Shoulder and Hand (DASH) and Wrightington wrist scores.
Any adverse effects were documented with particular emphasis on
residual pain, limitation of movement, infection, dislocation and
the need for revision surgery. Radiographic assessment was performed pre-operatively and at
three, six and 12 months post-operatively, and annually thereafter.
Arthroplasties were assessed for distal row intercarpal fusion and
loosening. Radiolucent zones around the components were documented
according to a system developed at our institution.Aims
Patients and Methods
The fundamental concept of open reduction and internal fixation
(ORIF) of ankle fractures has not changed appreciably since the
1960s and, whilst widely used, is associated with complications
including wound dehiscence and infection, prominent hardware and
failure. Closed reduction and intramedullary fixation (CRIF) using
a fibular nail, wires or screws is biomechanically stronger, requires
minimal incisions, and has low-profile hardware. We hypothesised
that fibular nailing in the elderly would have similar functional
outcomes to standard fixation, with a reduced rate of wound and
hardware problems. A total of 100 patients (25 men, 75 women) over the age of 65
years with unstable ankle fractures were randomised to undergo standard
ORIF or fibular nailing (11 men and 39 women in the ORIF group,
14 men and 36 women in the fibular nail group). The mean age was
74 years (65 to 93) and all patients had at least one medical comorbidity. Complications,
patient related outcome measures and cost-effectiveness were assessed
over 12 months.Aims
Patients and Methods
Extendible endoprostheses have been available for more than 30
years and have become more sophisticated with time. The latest generation
is ‘non-invasive’ and can be lengthened with an external magnetic
force. Early results have shown a worryingly high rate of complications
such as infection. This study investigates the incidence of complications
and the need for further surgery in a cohort of patients with a
non-invasive growing endoprosthesis. Between 2003 and June 2014, 50 children (51 prostheses) had a
non-invasive growing prosthesis implanted for a primary bone sarcoma.
The minimum follow-up was 24 months for those who survived. Their
mean age was 10.4 years (6 to 14). The incidence of complications
and further surgery was documented.Aims
Patients and Methods
This is the first prospective study to report the pre- and post-operative
patient reported outcomes and satisfaction scores following excision
of interdigital Morton’s neuroma. Between May 2006 and April 2013, we prospectively studied 99
consecutive patients (111 feet) who were to undergo excision of
a Morton’s neuroma. There were 78 women and 21 men with a mean age
at the time of surgery of 56 years (22 to 78). Patients completed
the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12
(SF-12) and a supplementary patient satisfaction survey three months
pre-operatively and six months post-operatively.Aims
Patients and Methods
Femoral impaction bone grafting was first developed in 1987 using
morselised cancellous bone graft impacted into the femoral canal
in combination with a cemented, tapered, polished stem. We describe
the evolution of this technique and instrumentation since that time. Between 1987 and 2005, 705 revision total hip arthroplasties
(56 bilateral) were performed with femoral impaction grafting using
a cemented femoral stem. All surviving patients were prospectively
followed for a mean of 14.7 years (9.8 to 28.3) with no loss to
follow-up. By the time of the final review, 404 patients had died.Aims
Patients and Methods
The mainstay of surgical correction of hallux valgus is first
metatarsal osteotomy, either proximally or distally. We present
a technique of combining a distal chevron osteotomy with a proximal
opening wedge osteotomy, for the correction of moderate to severe
hallux valgus. We reviewed 45 patients (49 feet) who had undergone double osteotomy.
Outcome was assessed using the American Orthopaedic Foot and Ankle
Society (AOFAS) and the Short Form (SF) -36 Health Survey scores.
Radiological measurements were undertaken to assess the correction. The mean age of the patients was 60.8 years (44.2 to 75.3). The
mean follow-up was 35.4 months (24 to 51).Aims
Patients and Methods
Risk of revision following total knee arthroplasty (TKA) is higher
in patients under 55 years, but little data are reported regarding
non-revision outcomes. This study aims to identify predictors of
dissatisfaction in these patients. We prospectively assessed 177 TKAs (157 consecutive patients,
99 women, mean age 50 years; 17 to 54) from 2008 to 2013. Age, gender,
implant, indication, body mass index (BMI), social deprivation,
range of movement, Kellgren-Lawrence (KL) grade of osteoarthritis
(OA) and prior knee surgery were recorded. Pre- and post-operative
Oxford Knee Score (OKS) as well as Short Form-12 physical (PCS)
and mental component scores were obtained. Post-operative range
of movement, complications and satisfaction were measured at one
year.Aims
Patients and Methods
In light of the growing number of elderly osteopenic
patients with distal humeral fractures, we discuss the history of
their management and current trends. Under most circumstances operative
fixation and early mobilisation is the treatment of choice, as it
gives the best results. The relative indications for and results

Our aim was to perform a systematic review of the literature
to assess the incidence of post-operative epidural haematomas and
wound infections after one-, or two-level, non-complex, lumbar surgery
for degenerative disease in patients with, or without post-operative
wound drainage. Studies were identified from PubMed and EMBASE, up to and including
27 August 2015, for papers describing one- or two-level lumbar discectomy
and/or laminectomy for degenerative disease in adults which reported
any form of subcutaneous or subfascial drainage.Aims
Patients and Methods
The aim of this study was to report the outcome following primary
fixation or a staged protocol for type C fractures of the tibial
plafond. We studied all patients who sustained a complex intra-articular
fracture (AO type C) of the distal tibia over an 11-year period.
The primary short-term outcome was infection. The primary long-term
outcome was the Foot and Ankle Outcome Score (FAOS).Aims
Patients and Methods
Obesity is a worldwide epidemic that has both
economic and health implications of enormous consequence. The obese
patients tend to have earlier symptoms related to osteoarthritis,
more peri-operative medical problems, higher rates of infection
and more technical difficulties intra-operatively following hip
and knee arthroplasty. Nevertheless, these patients have good long-term
clinical outcomes and implant survival rates and are often some of
the most satisfied patients after joint arthroplasty. Therefore,
obese patients should not be denied surgery based on their weight
alone. Cite this article:
The aim of this randomised controlled study was
to compare functional and radiological outcomes between modern cemented
and uncemented hydroxyapatite coated stems after one year in patients
treated surgically for a fracture of the femoral neck. A total of
141 patients aged >
65 years were included. Patients were randomised
to be treated with a cemented Exeter stem or an uncemented Bimetric
stem. The patients were reviewed at four and 12 months. The cemented group performed better than the uncemented group
for the Harris hip score (78 In conclusion, our data do not support the use of an uncemented
hydroxyapatite coated stem for the treatment of displaced fractures
of the femoral neck in the elderly. Cite this article:
We report our experience of performing an elbow
hemiarthroplasty in the treatment of comminuted distal humeral fractures
in the elderly patients. A cohort of 42 patients (three men and 39 women, mean age 72;
56 to 84) were reviewed at a mean of 34.3 months (24 to 61) after
surgery. Functional outcome was measured with the Mayo Elbow Performance
Score (MEPS) and range of movement. The disabilities of the arm,
shoulder and hand questionnaire (DASH) was used as a patient rated
evaluation. Complications and ulnar nerve function were recorded.
Plain radiographs were obtained to assess prosthetic loosening,
olecranon wear and heterotopic bone formation. The mean extension deficit was 23.5° (0° to 60°) and mean flexion
was 126.8° (90° to 145°) giving a mean arc of 105.5° (60° to 145°).
The mean MEPS was 90 (50 to 100) and a mean DASH score of 20 (0
to 63). Four patients had additional surgery for limited range of
movement and one for partial instability. One elbow was revised
due to loosening, two patients had sensory ulnar nerve symptoms,
and radiographic signs of mild olecranon wear was noted in five
patients. Elbow hemiarthroplasty for comminuted intra-articular distal
humeral fractures produces reliable medium-term results with functional
outcome and complication rates, comparable with open reduction and
internal fixation and total elbow arthroplasty. Cite this article:
Lumbar disc herniation (LDH) is uncommon in youth
and few cases are treated surgically. Very few outcome studies exist
for LDH surgery in this age group. Our aim was to explore differences
in gender in pre-operative level of disability and outcome of surgery
for LDH in patients aged ≤ 20 years using prospectively collected
data. From the national Swedish SweSpine register we identified 180
patients with one-year and 108 with two-year follow-up data ≤ 20
years of age, who between the years 2000 and 2010 had a primary
operation for LDH. Both male and female patients reported pronounced impairment
before the operation in all patient reported outcome measures, with
female patients experiencing significantly greater back pain, having
greater analgesic requirements and reporting significantly inferior
scores in EuroQol (EQ-5D-index), EQ-visual analogue scale, most aspects
of Short Form-36 and Oswestry Disabilities Index, when compared
with male patients. Surgery conferred a statistically significant
improvement in all registered parameters, with few gender discrepancies.
Quality of life at one year following surgery normalised in both
males and females and only eight patients (4.5%) were dissatisfied with
the outcome. Virtually all parameters were stable between the one-
and two-year follow-up examination. LDH surgery leads to normal health and a favourable outcome in
both male and female patients aged 20 years or younger, who failed
to recover after non-operative management. Cite this article:
The Swansea Morriston Achilles Rupture Treatment
(SMART) programme was introduced in 2008. This paper summarises
the outcome of this programme. Patients with a rupture of the Achilles
tendon treated in our unit follow a comprehensive management protocol
that includes a dedicated Achilles clinic, ultrasound examination,
the use of functional orthoses, early weight-bearing, an accelerated
exercise regime and guidelines for return to work and sport. The
choice of conservative or surgical treatment was based on ultrasound
findings. The rate of re-rupture, the outcome using the Achilles Tendon
Total Rupture Score (ATRS) and the Achilles Tendon Repair Score,
(AS), and the complications were recorded. An elementary cost analysis
was also performed. Between 2008 and 2014 a total of 273 patients presented with
an acute rupture 211 of whom were managed conservatively and 62
had surgical repair. There were three
re-ruptures (1.1%). There were 215 men and 58 women with a mean
age of 46.5 years (20 to 86). Functional outcome was satisfactory.
Mean ATRS and AS at four months was 53.0
( The SMART programme resulted in a low rate of re-rupture, a satisfactory
outcome, a reduced rate of surgical intervention and a reduction
in healthcare costs. Cite this article:
The aim of this study was to quantify the stability
of fracture-implant complex in fractures after fixation. A total
of 15 patients with an undisplaced fracture of the femoral neck,
treated with either a dynamic hip screw or three cannulated hip
screws, and 16 patients with an AO31-A2 trochanteric fracture treated
with a dynamic hip screw or a Gamma Nail, were included. Radiostereometric
analysis was used at six weeks, four months and 12 months post-operatively
to evaluate shortening and rotation. Migration could be assessed in ten patients with a fracture of
the femoral neck and seven with a trochanteric fracture. By four
months post-operatively, a mean shortening of 5.4 mm (-0.04 to 16.1)
had occurred in the fracture of the femoral neck group and 5.0 mm
(-0.13 to 12.9) in the trochanteric fracture group. A wide range
of rotation occurred in both types of fracture. Right-sided trochanteric
fractures seem more rotationally stable than left-sided fractures. This prospective study shows that migration at the fracture site
occurs continuously during the first four post-operative months,
after which stabilisation occurs. This information may allow the
early recognition of patients at risk of failure of fixation. Cite this article:
We reviewed 212 consecutive patients with adolescent
idiopathic scoliosis who underwent posterior spinal arthrodesis
using all pedicle screw instrumentation in terms of clinical, radiological
and Scoliosis Research Society (SRS)-22 outcomes. In Group 1 (51
patients), the correction was performed over two rods using bilateral
segmental pedicle screws. In Group 2 (161 patients), the correction
was performed over one rod using unilateral segmental pedicle screws
with the second rod providing stability of the construct
through two-level screw fixation at proximal and distal ends. The
mean age at surgery was
14.8 years in both groups. Comparison between groups showed no significant
differences with regard to age and Risser grade at surgery, pre-
and post-operative scoliosis angle, coronal Cobb correction, length
of hospital stay and SRS scores. Correction of upper thoracic curves
was significantly better in Group 1 (p = 0.02). Increased surgical time
and intra-operative blood loss was recorded in Group 1 (p <
0.001
and p = 0.04, respectively). The implant cost was reduced by mean
35% in Group 2 due to the lesser number of pedicle screws. Unilateral and bilateral pedicle screw techniques have both achieved
excellent deformity correction in adolescent patients with idiopathic
scoliosis, which was maintained at two-year follow-up. This has
been associated with high patient satisfaction and low complication
rates.
Moderate to severe hallux valgus is conventionally
treated by proximal metatarsal osteotomy. Several recent studies
have shown that the indications for distal metatarsal osteotomy
with a distal soft-tissue procedure could be extended to include
moderate to severe hallux valgus. The purpose of this prospective randomised controlled trial was
to compare the outcome of proximal and distal Chevron osteotomy
in patients undergoing simultaneous bilateral correction of moderate
to severe hallux valgus. The original study cohort consisted of 50 female patients (100
feet). Of these, four (8 feet) were excluded for lack of adequate
follow-up, leaving 46 female patients (92 feet) in the study. The
mean age of the patients was 53.8 years (30.1 to 62.1) and the mean
duration of follow-up 40.2 months (24.1 to 80.5). After randomisation,
patients underwent a proximal Chevron osteotomy on one foot and
a distal Chevron osteotomy on the other. At follow-up, the American Orthopedic Foot and Ankle Society
(AOFAS) hallux metatarsophalangeal interphalangeal (MTP-IP) score,
patient satisfaction, post-operative complications, hallux valgus
angle, first-second intermetatarsal angle, and tibial sesamoid position
were similar in each group. Both procedures gave similar good clinical
and radiological outcomes. This study suggests that distal Chevron osteotomy with a distal
soft-tissue procedure is as effective and reliable a means of correcting
moderate to severe hallux valgus as proximal Chevron osteotomy with
a distal soft-tissue procedure. Cite this article:
To assess the sustainability of our institutional
bone bank, we calculated the final product cost of fresh-frozen femoral
head allografts and compared these costs with the use of commercial
alternatives. Between 2007 and 2010 all quantifiable costs associated
with allograft donor screening, harvesting, storage, and administration
of femoral head allografts retrieved from patients undergoing elective
hip replacement were analysed. From 290 femoral head allografts harvested and stored as full
(complete) head specimens or as two halves, 101 had to be withdrawn.
In total, 104 full and 75 half heads were implanted in 152 recipients.
The calculated final product costs were €1367 per full head. Compared
with the use of commercially available processed allografts, a saving
of at least €43 119 was realised over four-years (€10 780 per year)
resulting in a cost-effective intervention at our institution. Assuming
a price of between €1672 and €2149 per commercially purchased allograft,
breakeven analysis revealed that implanting between 34 and 63 allografts
per year equated to the total cost of bone banking. Cite this article:
Studies describing the effect of body mass index (BMI) on the outcome of total hip replacement have been inconclusive and contradictory. We examined the effect of BMI on medium-term outcome in a cohort of 1617 patients who underwent a primary total hip replacement for osteoarthritis. These patients were followed prospectively for five years with the outcomes of dislocation, revision, duration of surgery and deep and superficial infection studied, as well as collecting Harris hip scores (HHS) and Short-Form 36 (SF-36) questionnaires pre-operatively and at review. A multivariate analysis was performed to see whether BMI is an independent predictor of poor outcome. We found that patients with a BMI of ? 35 kg/m2 have a 4.42 times higher rate of dislocation than those with a BMI <
25 kg/m2. Increasing BMI is also associated with superficial infection and poorer HHS and SF-36 scores at five years. These trends remain significant even when multivariate analysis adjusts for age, gender, prosthesis, operating consultant, pre-operative HHS and SF-36, and comorbidities including diabetes mellitus, cardiac disease and osteoporosis. Despite the increased risks, the five-year outcome scores indicate that obese patients have much to gain from total hip replacement. Thus total hip replacement should not be withheld from patients solely on the grounds of an elevated BMI. However, longer-term follow-up of this cohort is required to establish whether adverse outcomes become more evident with time.
The aim of this study was to examine the functional
outcome at ten years following lateral closing wedge high tibial osteotomy
for medial compartment osteoarthritis of the knee and to define
pre-operative predictors of survival and determinants of functional
outcome. 164 consecutive patients underwent high tibial osteotomy between
2000 and 2002. A total of 100 patients (100 knees) met the inclusion
criteria and 95 were available for review at ten years. Data were
collected prospectively and included patient demographics, surgical
details, long leg alignment radiographs, Western Ontario and McMaster Universities
osteoarthritis index (WOMAC) and Knee Society scores (KSS) pre-operatively
and at five and ten years follow-up. At ten years, 21 patients had been revised at a mean of five
years. Overall Kaplan–Meier survival was 87% (95% confidence interval
(CI) 81 to 94) and 79% (95% CI 71 to 87) at five and ten years,
respectively. When compared with unrevised patients, those who had
been revised had significantly lower mean pre-operative WOMAC Scores
(47 (21 to 85) This study has shown that improved survival is associated with
age <
55 years, pre-operative WOMAC scores >
45 and, a BMI <
30. In patients over 55 years of age with adequate pre-operative
functional scores, survival can be good and functional outcomes
can be significantly better than their younger counterparts. We
recommend the routine use of pre-operative functional outcome scores
to guide decision-making when considering suitability for high tibial osteotomy. Cite this article:
This study sought to determine the medium-term
patient-reported and radiographic outcomes in patients undergoing
surgery for hallux valgus. A total of 118 patients (162 feet) underwent
surgery for hallux valgus between January 2008 and June 2009. The
Manchester-Oxford Foot Questionnaire (MOXFQ), a validated tool for
the assessment of outcome after surgery for hallux valgus, was used
and patient satisfaction was sought. The medical records and radiographs
were reviewed retrospectively. At a mean of 5.2 years (4.7 to 6.0)
post-operatively, the median combined MOXFQ score was 7.8 (IQR:0
to 32.8). The median domain scores for pain, walking/standing, and social
interaction were 10 (IQR: 0 to 45), 0 (IQR: 0 to 32.1) and 6.3 (IQR:
0 to 25) respectively. A total of 119 procedures (73.9%, in 90 patients)
were reported as satisfactory but only 53 feet (32.7%, in 43 patients)
were completely asymptomatic. The mean (SD) correction of hallux
valgus, intermetatarsal, and distal metatarsal articular angles was
18.5° (8.8°), 5.7° (3.3°), and 16.6° (8.8°), respectively. Multivariable
regression analysis identified that an American Association of Anesthesiologists
grade of >
1 (Incident Rate Ratio (IRR) = 1.67, p-value = 0.011)
and recurrent deformity (IRR = 1.77, p-value = 0.003) were associated
with significantly worse MOXFQ scores. No correlation was found
between the severity of deformity, the type, or degree of surgical
correction and the outcome. When using a validated outcome score
for the assessment of outcome after surgery for hallux valgus, the
long-term results are worse than expected when compared with the
short- and mid-term outcomes, with 25.9% of patients dissatisfied
at a mean follow-up of 5.2 years. Cite this article:
Total knee replacement (TKR) is an operation
that can be performed with or without the use of a tourniquet. Meta-analyses
of the available Level-1 studies have demonstrated that the use
of a tourniquet leads to a significant reduction in blood loss.
The opponents for use of a tourniquet cite development of complications
such as skin bruising, neurovascular injury, and metabolic disturbance
as drawbacks. Although there may certainly be reason for concern
in arteriopathic patients, there is little evidence that routine
use of a tourniquet during TKR results in any of the above complications.
The use of a tourniquet, on the other hand, provides a bloodless
field that allows the surgeon to perform the procedure with expediency
and optimal visualisation. Blood conservation has gained great importance
in recent years due to increased understanding of the problems associated
with blood transfusion, such as increased surgical site infection
(due to immunomodulation effect), increased length of hospital stay
and increased cost. Based on the authors’ understanding of the available
evidence, the routine use of a tourniquet during TKR is justified
as good surgical practice. Cite this article:
We hypothesised there was no clinical value in
using an autologous blood transfusion (ABT) drain in either primary total
hip (THR) or total knee replacement (TKR) in terms of limiting allogeneic
blood transfusions when a modern restrictive blood management regime
was followed. A total of 575 patients (65.2% men), with a mean age
of 68.9 years (36 to 94) were randomised in this three-arm study
to no drainage (group A), or to wound drainage with an ABT drain
for either six hours (group B) or 24 hours (group C). The primary
outcome was the number of patients receiving allogeneic blood transfusion.
Secondary outcomes were post-operative haemoglobin (Hb) levels,
length of hospital stay and adverse events. This study identified only 41 transfused patients, with no significant
difference in distribution between the three groups (p = 0.857).
The mean pre-operative haemoglobin (Hb) value in the transfused
group was 12.8 g/dL (9.8 to 15.5) Cite this article:
The results of 41 consecutive total knee replacements performed on morbidly obese patients with a body mass index >
40 kg/m2, were compared with a matched group of 41 similar procedures carried out in non-obese patients (body mass index <
30 kg/m2). The groups were matched for age, gender, diagnosis, type of prosthesis, laterality and pre-operative Knee Society Score. We prospectively followed up the patients for a mean of 38.5 months (6 to 66). No patients were lost to follow-up. At less than four years after operation, the results were worse in the morbidly obese group compared with the non-obese, as demonstrated by inferior Knee Society Scores (mean knee score 85.7 and 90.5 respectively, p = 0.08; mean function score 75.6 and 83.4, p = 0.01), a higher incidence of radiolucent lines on post-operative radiographs (29% and 7%, respectively, p = 0.02), a higher rate of complications (32% and 0%, respectively, p = 0.001) and inferior survivorship using revision and pain as end-points (72.3% and 97.6%, respectively, p = 0.02). Patients with a body mass index >
40 kg/m2 should be advised to lose weight prior to total knee replacement and to maintain weight reduction. They should also be counselled regarding the inferior results which may occur if they do not lose weight before surgery.
The purpose of this study was to assess whether
the use of a joint-sparing technique such as curettage and grafting was
successful in eradicating giant cell tumours of the proximal femur,
or whether an alternative strategy was more appropriate. Between 1974 and 2012, 24 patients with a giant cell tumour of
the proximal femur were treated primarily at our hospital. Treatment
was either joint sparing or joint replacing. Joint-sparing treatment
was undertaken in ten patients by curettage with or without adjunctive
bone graft. Joint replacement was by total hip replacement in nine patients
and endoprosthetic replacement in five. All 11 patients who presented
with a pathological fracture were treated by replacement. Local recurrence occurred in five patients (21%): two were treated
by hip replacement, three by curettage and none with an endoprosthesis.
Of the ten patients treated initially by curettage, six had a successful
outcome without local recurrence and required no further surgery.
Three eventually needed a hip replacement for local recurrence and
one an endoprosthetic replacement for mechanical failure. Thus 18
patients had the affected joint replaced and only six (25%) retained
their native joint. Overall, 60% of patients without a pathological
fracture who were treated with curettage had a successful outcome. Cite this article:
The purpose of this study was to evaluate and
compare the effect of short segment pedicle screw instrumentation and
an intermediate screw (SSPI+IS) on the radiological outcome of type
A thoracolumbar fractures, as judged by the load-sharing classification,
percentage canal area reduction and remodelling. We retrospectively evaluated 39 patients who had undergone hyperlordotic
SSPI+IS for an AO-Magerl Type-A thoracolumbar fracture. Their mean
age was 35.1 (16 to 60) and the mean follow-up was 22.9 months (12
to 36). There were 26 men and 13 women in the study group. In total,
18 patients had a load-sharing classification score of seven and
21 a score of six. All radiographs and CT scans were evaluated for
sagittal index, anterior body height compression (%ABC), spinal
canal area and encroachment. There were no significant differences
between the low and high score groups with respect to age, duration
of follow-up, pre-operative sagittal index or pre-operative anterior
body height compression (p = 0.217, 0.104, 0.104, and 0.109 respectively).
The mean pre-operative sagittal index was 19.6° (12° to 28°) which
was corrected to -1.8° (-5° to 3°) post-operatively and 2.4° (0°
to 8°) at final follow-up (p = 0.835 for sagittal deformity). No
patient needed revision for loss of correction or failure of instrumentation. Hyperlordotic reduction and short segment pedicle screw instrumentation
and an intermediate screw is a safe and effective method of treating
burst fractures of the thoracolumbar spine. It gives excellent radiological
results with a very low rate of failure regardless of whether the
fractures have a high or low load-sharing classification score. Cite this article
A consecutive series of 320 patients with an
intracapsular fracture of the hip treated with a dynamic locking
plate (Targon Femoral Neck (TFN)) were reviewed. All surviving patients
were followed for a minimum of two years. During the follow-up period
109 patients died. There were 112 undisplaced fractures, of which three (2.7%) developed
nonunion or re-displacement and five (4.5%) developed avascular
necrosis of the femoral head. Revision to an arthroplasty was required
for five patients (4.5%). A further six patients (5.4%) had elective
removal of the plate and screws. There were 208 displaced fractures, of which 32 (15.4%) developed
nonunion or re-displacement and 23 (11.1%) developed avascular necrosis.
A further four patients (1.9%) developed a secondary fracture around
the TFN. Revision to a hip replacement was required for 43 patients
(20.7%) patients and a further seven (3.3%) had elective removal
of the plate and screws. It is suggested that the stronger distal fixation combined with
rotational stability may lead to a reduced incidence of complications
related to the healing of the fracture when compared with other
contemporary fixation devices but this needs to be confirmed in
further studies. Cite this article:
In 2012 we reviewed a consecutive series of 92
uncemented THRs performed between 1986 and 1991 at our institution
using the CLS Spotorno stem, in order to assess clinical outcome
and radiographic data at a minimum of 21 years. The series comprised
92 patients with a mean age at surgery of 59.6 years (39 to 77)
(M:F 43;49). At the time of this review, seven (7.6%) patients had died and
two (2.2%) were lost to follow-up. The 23-year Kaplan–Meier survival
rates were 91.5% (95% confidence intervals (CI) 85.4% to 97.6%;
55 hips at risk) and 80.3% (95% CI, 71.8% to 88.7%; 48 hips at risk)
respectively, with revision of the femoral stem or of any component
as endpoints. At the time of this review, 76 patients without stem
revision were assessed clinically and radiologically (mean follow-up
24.0 years (21.5 to 26.5)). For the 76 unrevised hips the mean Harris
hip score was 87.1 (65 to 97). Femoral osteolysis was detected in
five hips (6.6%) only in Gruen zone 7. Undersized stems were at
higher risk of revision owing to aseptic loosening (p = 0.0003).
Patients implanted with the stem in a varus position were at higher risk
of femoral cortical hypertrophy and thigh pain (p = 0.0006 and p
= 0.0007, respectively). In our study, survival, clinical outcome and radiographic data
remained excellent in the third decade after implantation. Nonetheless,
undersized stems were at higher risk of revision owing to aseptic
loosening. Cite this article:
