Aims. This study reports updates the previously published two-year clinical, functional, and radiological results of a group of patients who underwent transfibular total ankle arthroplasty (TAA), with follow-up extended to a minimum of five years. Methods. We prospectively evaluated 89 patients who underwent transfibular TAA for end-stage osteoarthritis. Patients’ clinical and radiological examinations were collected pre- and postoperatively at six months and then annually for up to five years of follow-up. Three patients were lost at the final follow-up with a total of 86 patients at the final follow-up. Results. A total of 86 patients were evaluated at a mean follow-up of 65.4 months (60 to 90). At five-year follow-up, statistically significant improvements (p < 0.001) were found in the mean American Orthopaedic Foot & Ankle Society Ankle Hindfoot Score (from 33.8 (SD 14.3) to 86.1 (SD 8.8)), visual analogue scale for pain (from 8.5 (SD 1.7) to 1.5 (SD 1.2)),
Persistent post-surgical pain and associated disability are common after a traumatic fracture repair. Preliminary evidence suggests that patients' beliefs and perceptions may influence their prognosis. We sought to explore this association. We used data from the Fluid Lavage of Open Wounds trial to determine, in 1560 open fracture patients undergoing surgical repair, the association between Somatic PreOccupation and Coping (captured by the SPOC questionnaire) and recovery at 1 year. Of the 1218 open fracture patients with complete data available for analysis, 813 (66.7%) reported moderate to extreme pain at 1 yr. The addition of SPOC scores to an adjusted regression model to predict persistent pain improved the concordance statistic from 0.66 to 0.74, and found the greatest risk was associated with high SPOC scores [odds ratio: 5.63, 99% confidence interval (CI): 3.59–8.84, absolute risk increase 40.6%, 99% CI: 30.8%, 48.6%]. Thirty-eight per cent (484 of 1277) reported moderate to extreme pain interference at 1 yr. The addition of SPOC scores to an adjusted regression model to predict pain interference improved the concordance statistic from 0.66 to 0.75, and the greatest risk was associated with high SPOC scores (odds ratio: 6.06, 99% CI: 3.97–9.25, absolute risk increase: 18.3%, 95% CI: 11.7%, 26.7%). In our adjusted multivariable regression models, SPOC scores at 6 weeks post-surgery accounted for 10% of the variation in
The management of severe acetabular bone defects poses a complex challenge in revision hip arthroplasty. Although biological fixation materials are currently dominant, cage has played an important role in complex acetabular revision in the past decades, especially when a biological prosthesis is not available. The purpose of this study is to report the long-term clinical and radiographic results of Paprosky type Ⅲ acetabular bone defects revised with cage and morselized allografts. We retrospectively analyzed 45 patients who underwent revision hip arthroplasty with cage and morselized allografts between January 2007 and January 2019. Forty-three patients were followed up. There were 19 Paprosky type IIIA bone defect patients and 24 Paprosky type IIIB bone defect patients and 7 patients of the 24 were also with pelvic discontinuity. Clinical assessment included Harris Hip Score (HHS) and
Unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) are well-established operative interventions in the treatment of knee osteoarthritis (KOA). However, which of these interventions is more beneficial, to patients with KOA, is not known and remains a topic of much debate. Aims: (i) To determine whether UKA or HTO is more beneficial in the treatment of isolated medial compartment KOA, via an assessment of patient-reported outcome measures (PROMs). (ii) To investigate the relationship between PROMs and radiographic parameters of knee joint orientation/alignment. This longitudinal observational study assessed a total of 42 patients that had undergone UKA (n=23) or HTO (n=19) to treat isolated medial compartment KOA. The PROMs assessed, pre-operatively and 1-year post-operatively, consisted of the: self-administered comorbidity questionnaire;
We identified a series of 128 patients who had unilateral open reconstruction of the anterior cruciate ligament (ACL) by a single surgeon between 1993 and 2000. In all, 79 patients were reviewed clinically and radiologically eight to 15 years after surgery. Assessment included measurement of the Lysholm and Tegner scores, the ACL quality-of-life score and the
The aim of this study is the comparative assessment of long term clinical (subjective and objective), functional and quality of life outcome data between primary and revision THA. 122 patients (130 hips) who underwent cementless revision THA of both components (TMT cup, Wagner SL stem, Zimmer Biomet) for aseptic loosening only (Group A) were compared to a matched group of 100 patients (100 hips) who underwent cementless primary THA for osteoarthritis (Synergy stem, R3 cup, Smith & Nephew) (Group B). Outcomes were evaluated with survival analysis curves, Harris hip score (HHS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford hip score (OHS),
We report the outcome at ten to 15 years of two-stage revision for hip infection in 99 patients using the Prostalac articulated hip spacer system. All the patients were contacted to determine their current functional and infection status using the Oxford-12,
Aims. 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. Patients and Methods. 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

Aims. The Advance Medial-Pivot total knee arthroplasty (TKA) was designed
to reflect contemporary data regarding the kinematics of the knee.
We wished to examine the long-term results obtained with this prosthesis
by extending a previous evaluation. Patients and Methods. We retrospectively evaluated prospectively collected data from
225 consecutive patients (41 men and 184 women; mean age at surgery
71 years, 52 to 84) who underwent 284 TKAs with a mean follow-up
of 13.4 years (11 to 15). Implant failure, complication rate, clinical (both
subjective and objective) and radiological outcome were assessed.
Pre- and post-operative clinical and radiographic data were available
at regular intervals for all patients. A total of ten patients (4.4%;
ten TKAs) were lost to follow-up. Results. Survival analysis at 15 years showed a cumulative success rate
of 97.3% (95% confidence interval (CI) 96.7 to 97.9) for revision
for any reason, of 96.4% (95% CI 95.2 to 97.6) for all operations,
and 98.8% (95% CI 98.2 to 99.4) for aseptic loosening as an end
point. Three TKAs (1.06%) were revised due to aseptic loosening,
two (0.7%) due to infection, one (0.35%) due to instability and
one (0.35%) due to a traumatic dislocation. All patients showed
a statistically significant improvement on the Knee Society Score
(p = 0.001), Western Ontario and McMaster University Osteoarthritis
Index (p = 0.001),
Aims. We conducted a randomised controlled trial to assess the accuracy
of positioning and alignment of the components in total knee arthroplasty
(TKA), comparing those undertaken using standard intramedullary
cutting jigs and those with patient-specific instruments (PSI). Patients and Methods. There were 64 TKAs in the standard group and 69 in the PSI group. The post-operative hip-knee-ankle (HKA) angle and positioning
was investigated using CT scans. Deviation of >
3° from the planned
position was regarded as an outlier. The operating time, Oxford

Objectives. This study reports on a secondary exploratory analysis of the early clinical outcomes of a randomised clinical trial comparing robotic arm-assisted unicompartmental knee arthroplasty (UKA) for medial compartment osteoarthritis of the knee with manual UKA performed using traditional surgical jigs. This follows reporting of the primary outcomes of implant accuracy and gait analysis that showed significant advantages in the robotic arm-assisted group. Methods. A total of 139 patients were recruited from a single centre. Patients were randomised to receive either a manual UKA implanted with the aid of traditional surgical jigs, or a UKA implanted with the aid of a tactile guided robotic arm-assisted system. Outcome measures included the American Knee Society Score (AKSS), Oxford Knee Score (OKS), Forgotten Joint Score, Hospital Anxiety Depression Scale, University of California at Los Angeles (UCLA) activity scale,
Introduction. Patient reported outcome measures (PROMs) are increasingly used as quality benchmarks in total joint arthroplasty (TJA). The objective of this study was to investigate whether PROMs correlate with patient satisfaction, which is arguably the most important and desired outcome. Methods. An institutional joint database was queried for patients who underwent primary, elective, unilateral TJA. Eligible patients were asked to complete a satisfaction survey at final follow-up. Correlation coefficients (R) were calculated to quantify the relationship between patient satisfaction and prospectively collected PROMs. We explored a wide range of PROMs including Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC);
Negative pressure wound therapy (NPWT) is commonly used to manage severe open fracture wounds. The recently completed X randomized controlled trial (RCT) evaluated the effect of NPWT versus standard wound management on 12-month disability and rate of deep infection among patients with severe open fractures of the lower limb and reported no differences. Using data from the Y trial of open fracture patients, we aimed to evaluate the impact of NPWT on the odds of having deep infections and health-related quality of life (HRQL). Our analyses included participants from the Y trial who had Gustilo II and III lower extremity fractures. To adjust for the influence of injury characteristics on type of dressing received, a propensity score was developed from the dataset. A one-to-one matching algorithm was then used to pair patients with a similar propensity for NPWT. Mixed effects logistic regression was used to evaluate the association between type of wound dressing and development of a deep infection requiring operative management (dependent variable) in the matched cohort. Gustilo type, irrigation solution, fracture location, mechanism of injury, and degree of contamination were included as adjustment variables. To determine any differences in HRQL between the NPWT and standard wound dressing groups, we conducted two multi-level models with three levels (centre, patient, and time) and included
Reverse shoulder arthroplasty (RSA) has an increasing effective use in the treatment of patients with a variety of diagnoses, including rotator cuff deficiency, inflammatory arthritis, or failed shoulder prostheses. Glenoid bone loss is not uncommonly encountered in these cases due to the significant wear. Severe bone loss can compromise glenoid baseplate positioning and fixation, consequently increasing the risk for early component loosening, instability, and scapular notching. To manage severe glenoid bone deficiencies, bone grafts are commonly used. Although, many studies report outcome of bone grafting in revision RSA, the literature on humeral head autograft for glenoid bone loss in primary RSA is less robust. The purpose of this study is to evaluate the clinical and radiographic outcomes of primary RSA with humeral head autograft for glenoid bone loss at our institution. Institutional review board approval was obtained to retrospectively review the records of 22 consecutive primary RTSA surgeries in 21 patients with humeral head autograft for glenoid bone loss between January 2008 and December 2016. Five patients died during follow-up, three were unable to be contacted and one refused to participate, leaving a final study cohort of 12 patients with 13 shoulders that underwent RSA. All patients had a clinical evaluation including detailed ROM and clinical evaluation using the American Shoulder and Elbow Surgeons (ASES) Score, Constant Score, Western Ontario Osteoarthritis of the Shoulder Index (WOOS), and
Background. The acetabular labrum provides sealing function and a degree of hip joint stability. Previous early(16 month) and mid-term(mean 3.5 years) follow-up of this cohort reported better patient related outcome measures in the refixation group. Methods. We reported patients who underwent labral debridement/focal labral excision during a period before the development of labral repair techniques. Patients with labral tears thought to be repairable with our current arthroscopic technique were compared with patients who underwent labral refixation. In 46 hips, the labrum was focally excised/debrided (group 1); in 54 hips, the labrum was refixed (group 2). Outcomes were measured with modified-Harris-Hip-Score (mHHS),
Fractures of the tibial shaft are common injuries,
but there are no long-term outcome data in the era of increased surgical
management. The aim of this prospective study was to assess the
clinical and functional outcome of this injury at 12 to 22 years.
Secondary aims were to determine the short- and long-term mortality,
and if there were any predictors of clinical or functional outcome
or mortality. From a prospective trauma database of 1502 tibial
shaft fractures in 1474 consecutive adult patients, we identified
a cohort of 1431 tibial diaphyseal fractures in 1403 patients, who
fitted our inclusion criteria. There were 1024 men, and mean age
at injury was 40.6 years. Fractures were classified according to
the AO system, and open fractures graded after Gustilo and Anderson.
Requirement of fasciotomy, time to fracture union, complications,
incidence of knee and ankle pain at long-term follow-up, changes in
employment and the patients’ social deprivation status were recorded.
Function was assessed at 12 to 22 years post-injury using the Short
Musculoskeletal Function Assessment and
Aims. The Fluid Lavage in Open Fracture Wounds (FLOW) trial was a multicentre,
blinded, randomized controlled trial that used a 2 × 3 factorial
design to evaluate the effect of irrigation solution (soap versus normal
saline) and irrigation pressure (very low versus low versus high)
on health-related quality of life (HRQL) in patients with open fractures.
In this study, we used this dataset to ascertain whether these factors
affect whether HRQL returns to pre-injury levels at 12-months post-injury. Patients and Methods. Participants completed the
This study aimed to evaluate the effect of clavicular shortening, measured by three-dimensional computerized tomography (3DCT), on functional outcomes and satisfaction in patients with healed, displaced, midshaft clavicle fractures up to one year following injury. The data used in this study were collected as part of a multicenter, prospective randomized control trial comparing open reduction and plate fixation with nonoperative treatment for displaced midshaft clavicle factures. Patients who were randomized to nonoperative treatment and who had healed by one year were included. Clavicle shortening relative to the uninjured contralateral clavicle was measured on 3DCT. Outcome analysis was conducted at six weeks, three months, six months and one year following injury and included the Disabilities of the Arm, Shoulder and Hand (DASH), Constant and
Patient reported outcomes and satisfaction scores following excision of interdigital Morton's neuroma have been recently established. However, little is known regarding what patient factors affect these outcomes. This is the first and largest prospective study to determine which patient factors influence surgical outcome following Morton's neuroma excision. Over a seven-year period, 99 consecutive patients (112 feet) undergoing surgical excision of Morton's neuroma were prospectively studied. 78 patients were female with a mean age at operation of 56 years. Patient recorded outcomes and satisfaction were measured using the Manchester-Oxford Foot Questionnaire (MOXFQ),
A prospective cohort of 222 patients who underwent revision hip replacement between April 2001 and March 2004 was evaluated to determine predictors of function, pain and activity level between one and two years post-operatively, and to define quality of life outcomes using validated patient reported outcome tools. Predictive models were developed and proportional odds regression analyses were performed to identify factors that predict quality of life outcomes at one and two years post-operatively. The dependent outcome variables were the Western Ontario and McMaster Osteoarthritis Index (WOMAC) function and pain scores, and University of California Los Angeles activity scores. The independent variables included patient demographics, operative factors, and objective quality of life parameters, including pre-operative WOMAC, and the
Introduction. Hip and knee replacements are being performed at increasing rates and currently account for one of the largest procedure expenditures in the Medicare budget. Outcomes of total knee replacement (TKR) depend on surgeon, patient and implant factors. The impact that the specific implants might have on patient-reported outcomes is unknown. The primary purpose of this study was to evaluate the patient-reported functional outcomes and satisfaction after primary total knee arthroplasty in patients with osteoarthritis who underwent TKR using five different brands of posterior-stabilized implants. Specifically, the aim was to evaluate for any difference in patient-reported outcomes based on implant brand used. The hypothesis was that there would be no difference in functional outcome that could be attributed to the implant used in primary TKR. Methods. Using our institution's total joint arthroplasty registry, we identified 4,135 patients who underwent total knee replacement (TKR) using one of the five most common implant brands used at our institution. These included Biomet Vanguard (N=211 patients), Depuy/Johnson&Johnson Sigma (N=221), Exactech OptetrakLogic (N=1,507), Smith & Nephew Genesis II (N=1,414), and Zimmer NexGen (N=779). Only posterior-stabilized primary TKRs in patients with osteoarthritis were included. Patients were evaluated preoperatively using the Knee Osteoarthritis Outcomes Score (KOOS), Lower Extremity Activity Scale (LEAS), and
Objective. Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA) bring relief of pain and functional disability to patients with end stage osteoarthritis, however the literature on their impact on patients’ level of physical activity (PA) is scarce. Methods. Cross-sectional study, performed in 2012, in 515 patients who underwent THA/TKA surgery in 2010–2011 and a random sample of persons aged >40 years from the Dutch general population participating in a national survey in the same period. PA in minutes per week (min/week) and adherence to the Dutch recommendation for health enhancing PA was measured by means of the Short QUestionnaire to ASsess Health enhancing PA (SQUASH) Additional assessments included socio-demographic characteristics, the presence of comorbidities, BMI and
Background. Over 96% of primary total hip replacements (THR) recorded in the National Joint Registry (NJR) are performed through a posterior or lateral surgical approach. There is no high quality evidence available to support the use of one approach over the other in primary THR and even less evidence when the outcome of revision THR is considered. Methods. Questionnaires were sent to 267 patients who had revision hip replacements between January 2006 and March 2010 for aseptic loosening. They rated their pain from 0–10, and used the Self-Administered Patient Satisfaction Scale (SAPS), Oxford Hip Score (OHS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and
Current knowledge regarding outcomes following surgical treatment of Morton's neuroma remains incomplete. 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. Over a seven year period, 99 consecutive patients (112 feet) undergoing surgical excision of Morton's neuroma were prospectively studied. 78 patients were female with a mean age at operation of 56 years. Patient recorded outcomes and satisfaction were measured using the Manchester-Oxford Foot Questionnaire (MOXFQ),

We explored the outcome of staged bilateral total
knee replacement (TKR) for symmetrical degenerative joint disease
and deformity in terms of patient expectations, functional outcome
and satisfaction. From 2009 to 2011, 70 consecutive patients (41
female) with a mean age of 71.7 years (43 to 89) underwent 140 staged
bilateral TKRs at our institution, with a mean time between operations
of 7.8 months (2 to 25). Patients were assessed pre-operatively
and at six and 12 months post-operatively using the
Despite a lack of long-term follow-up, there
is an increasing trend towards using femoral heads of large diameter
in total hip replacement (THR), partly because of the perceived
advantage of lower rates of dislocation. However, increasing the
size of the femoral head is not the only way to reduce the rate
of dislocation; optimal alignment of the components and repair of
the posterior capsule could achieve a similar effect. . In this prospective study of 512 cemented unilateral THRs (Male:Female
230:282) performed between 2004 and 2011, we aimed to determine
the rate of dislocation in patients who received a 22 mm head on
a 9/10 Morse taper through a posterior approach with capsular repair
and using the transverse acetabular ligament (TAL) as a guide for the
alignment of the acetabular component. The mean age of the patients
at operation was 67 years (35 to 89). The mean follow-up was 2.8
years (0.5 to 6.6). Pre- and post-operative assessment included

Radiological evidence of post-traumatic osteoarthritis
(PTOA) after fracture of the tibial plateau is common but end-stage arthritis
which requires total knee arthroplasty is much rarer. The aim of this study was to examine the indications for, and
outcomes of, total knee arthroplasty after fracture of the tibial
plateau and to compare this with an age and gender-matched cohort
of TKAs carried out for primary osteoarthritis. Between 1997 and 2011, 31 consecutive patients (23 women, eight
men) with a mean age of 65 years (40 to 89) underwent TKA at a mean
of 24 months (2 to 124) after a fracture of the tibial plateau.
Of these, 24 had undergone ORIF and seven had been treated non-operatively.
Patients were assessed pre-operatively and at 6, 12 and >

The ideal bearing surface for young patients
undergoing total hip replacement (THR) remains controversial. We report
the five-year results of a randomised controlled trial comparing
the clinical and radiological outcomes of 102 THRs in 91 patients
who were <
65 years of age. These patients were randomised to
receive a cobalt–chrome on ultra-high-molecular-weight polyethylene,
cobalt–chrome on highly cross-linked polyethylene, or a ceramic-on-ceramic
bearing. In all, 97 hip replacements in 87 patients were available
for review at five years. Two hips had been revised, one for infection
and one for peri-prosthetic fracture. At the final follow-up there were no significant differences
between the groups for the mean Western Ontario and McMaster Universities

We report on the use of the Ilizarov method to
treat 40 consecutive fractures of the tibial shaft (35 AO 42C fractures and
five AO 42B3 fractures) in adults. There were 28 men and
12 women with a mean age of 43 years (19 to 81). The series included
19 open fractures (six Gustilo grade 3A and 13 grade 3B) and 21
closed injuries. The mean time from injury to application of definitive
Ilizarov frame was eight days (0 to 35) with 36 fractures successfully
uniting without the need for any bone-stimulating procedure. The
four remaining patients with nonunion healed with a second frame.
There were no amputations and no deep infections. None required
intervention for malunion. The total time to healing was calculated
from date of injury to removal of the frame, with a median of 166
days (mean 187, (87 to 370)). Minor complications included snapped
wires in two patients and minor pin-site infections treated with
oral antibiotics in nine patients (23%). Clinical scores were available
for 32 of the 40 patients at a median of 55 months (mean 62, (26
to 99)) post-injury, with ‘good’ Olerud and Molander ankle scores
(median 80, mean 75, (10 to 100)), ‘excellent’ Lysholm knee scores
(median 97, mean 88, (29 to 100)), a median Tegner activity score
of 4 (mean 4, (0 to 9)) (comparable to ‘moderately heavy labour
/ cycling and jogging’) and
Introduction: Foot and ankle involvement in rheumatoid arthritis is common. Pain and disability secondary to planovalgus deformity and the arthritic process are difficult to control with conservative measures. Arthroplasty of the ankle is associated with high failure rates and does not completely correct the deformity. Arthrodesis of the hindfoot is a good option to alleviate pain, correct the deformity and improve functional ability, however has not been well reported in the literature. Aims: To determine change in quantitative measures of patient health, pain and functional ability following hindfoot arthrodesis in patients with rheumatoid arthritis, and to assess patient satisfaction postoperatively. Methods: 24 consecutive additive hindfoot arthrodeses were performed by a single surgeon on 22 patients with rheumatoid arthritis. Patients were assessed preoperatively using the
Purpose: The popularity of intramedullary nails (IMN) for trochanteric hip fractures has grown substantially with little supportive evidence that IMN are superior to conventional sliding hip screws (SHS). We aimed to assess the impact of SHS or IMN intramedullary nailing on functional outcomes and rates of re-operation in elderly patients with fractures. Method: We conducted a multi-center, pilot randomized trial including three clinical sites across Sweden, Denmark, and Canada. We randomized 85 elderly patients with stable and unstable trochanteric hip fractures to either SHS or an IMN. The primary outcome, revision surgery, was independently adjudicated at one year. Secondary functional outcomes included the Parker Mobility Score (PMS), the Merle D’Aubigne Score, the
Purpose. Identifying optimal treatment strategies for inpatients with traumatic foot and ankle injuries has been hampered by a wide variety of outcome measures with unproven reliability and validity. It remains plausible that the choice of functional outcome measures may influence measurement of treatment effects. This prospective observational study aims to measure the correlation and agreement across six functional outcome measures in patients with traumatic foot and ankle injuries. Methods. Patients 18 years of age or older with a traumatic foot or ankle injury completed the
Introduction The tibial component of a total knee arthroplasty is subjected to eccentric medial and lateral plateau tibial loading during various phases of stance. The resultant coronal planar tilting forces may provoke early subsidence and loosening. The addition of a long non cemented stem is postulated to act as an outrigger, diminishing the rate of aseptic loosening. Methods Two hundred and thirteen primary total knee arthroplasties using proximally cemented tibial components with long non cemented Pressfit stems have been reviewed. Stem lengths varied from 110 mm to 140 mm. Patients were seen at an average of 8.7 years after surgery (two to 13 years) and were assessed using the Knee Society (IKS) pain and function scores, IKS radiographic analysis and
Materials and Methods: Consecutive 39 patients who underwent first metatarsophalangeal joint (MTPJ) arthrodesis for hallux rigidus were assessed clinically, radiographically and functionally at a mean follow up of 21.45 months. Clinical assessment was performed by two blinded assessors in a specially arranged research clinic. Radiological examinations were performed separately by two independent researchers on digitalised weight bearing radiographs. Functional outcome was assessed using American Orthopaedic Foot and Ankle Society (AOFAS) hallux score and a
In the litterature patients suffering Mb. Scheuermann (MS) have been reported to experience more back pain and other back related constrains compared to subjects matched for age and sex. We have been unable to find publications on health-related quality of life by SF-12 or SF-36 in MS. The aim of the present study was to compare health-related quality of life status in MS to the background population. Materials and Methods: The present cohorts are derived from The Danish Twin Registry and consist of all Danish twins born from 1931 through 1982. This twin cohort has been shown to very closely resemble the general Danish population. A total of 46,418 twins received and 75% returned a questionnaire of which 34,007(97.3 %) answered the question ‘Have you been diagnosed with Scheuermann’s disease?’ Included in the questionnaire were the standardised questions for The Medical Outcome Study
Introduction: Clubfoot – Congenital talipes equinovarus (CTEV) – is one of the most common congenital conditions requiring orthopaedic surgery. However little is known about the impact on health-related quality of life in these patients. A score on physical- and mental-health is used for this purpose. The aim of the present study was to compare health-related quality of life in CTEV to a background population. Materials and Methods: The Odense based Danish Twin Registry (DTR) is unique as it contains data on all 73,000 twin pairs born in Denmark over the last 130 years. All 46,418 twins born from 1931 through 1982 received an Omnibus questionnaire in the spring of 2002. The incidence of CTEV was self-reported. Included in the questionnaire were questions for The Medical Outcome Study
Background:. Custom cutting guides (CCG) in total knee arthroplasty (TKA) use preoperative 3-dimensional imaging to fabricate cutting blocks specific to a patient's native anatomy. To date, small cohorts and short follow-up have limited reports studying clinical and functional outcomes of CCGs versus standard intramedullary and extramedullary alignment instrumentation. The purpose of this study was to determine if CCGs improve clinical outcomes versus standard alignment guides following TKA at a mean of 2 years postoperatively. Methods:. This was a prospective cohort study of a consecutive series of patients undergoing primary TKA using the same cruciate-retaining, cemented system between January 2009 and April 2012. Exclusion criteria were patients with prior open knee surgery, a flexion contracture of greater than 20 degrees, a distal femoral or proximal tibial defect requiring a metal or allograft augment, the use of either femoral or tibial stem extensions, or a contraindication to obtaining a magnetic resonance imaging (MRI) scan. All patients were offered the option of receiving a preoperative MRI and TKA with CCGs, and each patient self-selected for either the CCG or standard cohort. The first 95 patients that selected CCGs were compared with the first 95 that were performed with standard instrumentation. The alignment goal for all TKAs was a hip-knee-ankle (HKA) angle of 0 degrees with the femoral and tibial components aligned perpendicular to the mechanical axis.

Introduction: The aims of this study were to. determine predictors of pain, function and activity level 1–2 years after revision hip arthroplasty and. define quality of life outcomes after revision total hip replacement. Methods: A prospective cohort of 222 patients who underwent revision hip arthroplasty were evaluated. Predictive models were developed and proportional odds regression analyses were performed to identify factors that predict quality of life outcomes at 1 and 2 years post surgery. The dependent outcome variables were WOMAC function, pain and UCLA activity. The independent variables included patient demographic, surgery specific and objective parameters including baseline Western Ontario McMaster Universities (WOMAC) osteoarthritis index, and the
Introduction:. While indications for total knee (TKA) and hip arthroplasty (THA) have expanded over the last 35 years, implant labeling has largely remained stagnant, with conditions including obesity, developmental dysplasia, and many others (Table 1) still considered as contraindications. Implant labeling has not co-evolved with surgical indications, as most orthopaedic implants are cleared through the 510(k) process, which conserves the labeling of the predicate device. While surgeons can legally use devices for off-label indications, the scrutiny regarding off-label use of orthopaedic implants has intensified. The objective of this study was to determine the incidence of off-label use at our institution, define the risk in terms of revision rate associated with off-label use, and to compare activity level, functional outcomes, and general health outcomes for on- and off-label TKA and THA patients. Methods:. Patients who underwent primary TKA or THA at a large academic tertiary referral center between January 1, 2010 and June 30, 2010 were considered for the study (n = 705).

Metal allergy in knee arthroplasty patients is a controversial topic. We aimed to conduct a scoping review to clarify the management of metal allergy in primary and revision total knee arthroplasty (TKA). Studies were identified by searching electronic databases: Cochrane Central Register of Controlled Trials, Ovid MEDLINE, and Embase, from their inception to November 2020, for studies evaluating TKA patients with metal hypersensitivity/allergy. All studies reporting on diagnosing or managing metal hypersensitivity in TKA were included. Data were extracted and summarized based on study design, study population, interventions and outcomes. A practical guide is then formulated based on the available evidence.Aims

Injuries to the hamstring muscle complex are common in athletes, accounting for between 12% and 26% of all injuries sustained during sporting activities. Acute hamstring injuries often occur during sports that involve repetitive kicking or high-speed sprinting, such as American football, soccer, rugby, and athletics. They are also common in watersports, including waterskiing and surfing. Hamstring injuries can be career-threatening in elite athletes and are associated with an estimated risk of recurrence in between 14% and 63% of patients. The variability in prognosis and treatment of the different injury patterns highlights the importance of prompt diagnosis with magnetic resonance imaging (MRI) in order to classify injuries accurately and plan the appropriate management. Low-grade hamstring injuries may be treated with nonoperative measures including pain relief, eccentric lengthening exercises, and a graduated return to sport-specific activities. Nonoperative management is associated with highly variable times for convalescence and return to a pre-injury level of sporting function. Nonoperative management of high-grade hamstring injuries is associated with poor return to baseline function, residual muscle weakness and a high-risk of recurrence. Proximal hamstring avulsion injuries, high-grade musculotendinous tears, and chronic injuries with persistent weakness or functional compromise require surgical repair to enable return to a pre-injury level of sporting function and minimize the risk of recurrent injury. This article reviews the optimal diagnostic imaging methods and common classification systems used to guide the treatment of hamstring injuries. In addition, the indications and outcomes for both nonoperative and operative treatment are analyzed to provide an evidence-based management framework for these patients. Cite this article:
To analyse the influence of upper extremity trauma on the long-term
outcome of polytraumatised patients. A total of 629 multiply injured patients were included in a follow-up
study at least ten years after injury (mean age 26.5 years, standard
deviation 12.4). The extent of the patients’ injury was classified
using the Injury Severity Score. Outcome was measured using the
Hannover Score for Polytrauma Outcome (HASPOC), Short Form (SF)-12, rehabilitation
duration, and employment status. Outcomes for patients with and
without a fracture of the upper extremity were compared and analysed
with regard to specific fracture regions and any additional brachial
plexus lesion.Aims
Patients and Methods
The number of rotator cuff repairs that are undertaken is increasing. Reverse shoulder arthroplasty (RSA) is the procedure of choice for patients with rotator cuff arthropathy. We sought to determine whether patients who underwent rotator cuff repair and subsequent RSA had different outcomes compared with a matched control group who underwent RSA without a previous rotator cuff repair. All patients with a history of rotator cuff repair who underwent RSA between 2000 and 2015 with a minimum follow-up of two years were eligible for inclusion as the study group. Outcomes, including the American Shoulder and Elbow Surgeons (ASES) scores, were compared with a matched control group of patients who underwent RSA without having previously undergone rotator cuff repair.Aims

Preservation of posterior condylar offset (PCO) has been shown to correlate with improved functional results after primary total knee arthroplasty (TKA). Whether this is also the case for revision TKA, remains unknown. The aim of this study was to assess the independent effect of PCO on early functional outcome after revision TKA. A total of 107 consecutive aseptic revision TKAs were performed by a single surgeon during an eight-year period. The mean age was 69.4 years (39 to 85) and there were 59 female patients and 48 male patients. The Oxford Knee Score (OKS) and Short-form (SF)-12 score were assessed pre-operatively and one year post-operatively. Patient satisfaction was also assessed at one year. Joint line and PCO were assessed radiographically at one year.Objectives
Methods
The purpose of our study is to summarise the current scientific
findings regarding the impact of obesity on total hip arthroplasty
(THA); specifically the influence of obesity on the timing of THA,
incidence of complications, and effect on clinical and functional
outcomes. We performed a systematic review that was compliant with the
Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines to identify prospective studies from the PubMed/Medline,
Embase, and Cochrane Library databases that evaluated primary THA
in obese (body mass index (BMI) ≥ 30 kg/m2) patients.Aims

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 with diabetes are at increased risk of wound complications
after open reduction and internal fixation of unstable ankle fractures.
A fibular nail avoids large surgical incisions and allows anatomical
reduction of the mortise. We retrospectively reviewed the results of fluoroscopy-guided
reduction and percutaneous fibular nail fixation for unstable Weber
type B or C fractures in 24 adult patients with type 1 or type 2
diabetes. The re-operation rate for wound dehiscence or other indications
such as amputation, mortality and functional outcomes was determined.Aims

Patient specific instrumentation (PSI) uses advanced
imaging of the knee (CT or MRI) to generate individualised cutting
blocks aimed to make the procedure of total knee arthroplasty (TKA)
more accurate and efficient. However, in this era of healthcare
cost consciousness, the value of new technologies needs to be critically
evaluated. There have been several comparative studies looking at

Few reports compare the contribution of the talonavicular articulation
to overall range of movement in the sagittal plane after total ankle
arthroplasty (TAA) and tibiotalar arthrodesis. The purpose of this
study was to assess changes in ROM and functional outcomes following
tibiotalar arthrodesis and TAA. Patients who underwent isolated tibiotalar arthrodesis or TAA
with greater than two-year follow-up were enrolled in the study.
Overall arc of movement and talonavicular movement in the sagittal
plane were assessed with weight-bearing lateral maximum dorsiflexion
and plantarflexion radiographs. All patients completed Short Form-12
version 2.0 questionnaires, visual analogue scale for pain (VAS)
scores, and the Foot and Ankle Ability Measure (FAAM).Aims

Controversy remains whether the contralateral
hip should be fixed in patients presenting with unilateral slipped capital
femoral epiphysis (SCFE). This retrospective study compares the
outcomes and cost of those patients who had prophylactic fixation
with those who did not. Between January 2000 and December 2010 a total of 50 patients
underwent unilateral fixation and 36 had prophylactic fixation of
the contralateral hip. There were 54 males and 32 females with a
mean age of 12.3 years (9 to 16). The rate of a subsequent slip
without prophylactic fixation was 46%. The risk of complications
was greater, the generic health measures (Short Form-12 physical
(p <
0.001) and mental (p = 0.004) summary scores) were worse.
Radiographic cam lesions in patients presenting with unilateral
SCFE were only seen in patients who did not have prophylactic fixation.
Furthermore, prophylactic fixation of the contralateral hip was
found to be a cost-effective procedure, with a cost per quality
adjusted life year gained of £1431 at the time of last follow-up. Prophylactic fixation of the contralateral hip is a cost-effective
operation that limits the morbidity from the complications of a
further slip, and the diminished functional outcome associated with
unilateral fixation. Cite this article:
Patients from a randomised trial on resurfacing
hip arthroplasty (RHA) (n = 36, 19 males; median age 57 years, 24
to 65) comparing a conventional 28 mm metal-on-metal total hip arthroplasty
(MoM THA) (n = 28, 17 males; median age 59 years, 37 to 65) and
a matched control group of asymptomatic patients with a 32 mm ceramic-on-polyethylene
(CoP) THA (n = 33, 18 males; median age 63 years, 38 to 71) were
cross-sectionally screened with metal artefact reducing sequence-MRI
(MARS-MRI) for pseudotumour formation at a median of 55 months (23
to 72) post-operatively. MRIs were scored by consensus according
to three different classification systems for pseudotumour formation. Clinical scores were available for all patients and metal ion
levels for MoM bearing patients. Periprosthetic lesions with a median volume of 16 mL (1.5 to
35.9) were diagnosed in six patients in the RHA group (17%), one
in the MoM THA group (4%) and six in the CoP group (18%). The classification
systems revealed no clear differences between the groups. Solid
lesions (n = 3) were exclusively encountered in the RHA group. Two patients
in the RHA group and one in the MoM THA group underwent a revision
for pseudotumour formation. There was no statistically significant
relationship between clinical scoring, metal ion levels and periprosthetic
lesions in any of the groups. Periprosthetic fluid collections are seen on MARS-MRI after conventional
CoP THA and RHA and may reflect a soft-tissue collection or effusion. Currently available MRI classification systems seem to score
these collections as pseudotumours, causing an-overestimatation
of the incidence of pseudotumours. Cite this article:
The June 2014 Knee Roundup360 looks at: acute repair preferable in hamstring ruptures; osteoarthritis a given in ACL injury, even with reconstruction?; chicken and egg: patellofemoral dysfunction and hip weakness; meniscal root tears as bad as we thought; outcomes in the meniscus; topical NSAIDs have a measurable effect on synovitis; nailing for tibial peri-prosthetic fracture.
The benefit of arthroscopy of the hip in the
treatment of femoroacetabular impingement (FAI) in terms of quality
of life (QoL) has not been reported. We prospectively collected
data on 612 patients (257 women (42%) and 355 men (58%)) with a
mean age at the time of surgery of 36.7 years (14 to 75) who underwent
arthroscopy of the hip for FAI under the care of a single surgeon.
The minimum follow-up was one year (mean 3.2 years (1 to 7)). The
responses to the modified Harris hip score were translated using
the Rosser Index Matrix in order to provide a QoL score. The mean
QoL score increased from 0.946 (-1.486 to 0.995) to 0.974 (0.7 to
1) at one year after surgery (p <
0.001). The mean QoL score
in men was significantly higher than in women, both before and one
year after surgery (both p <
0.001). However, the mean change
in the QoL score was not statistically different between men and
women (0.02 (-0.21 to 0.27) and 0.04 (-0.16 to 0.87), respectively;
p = 0.12). Linear regression analysis revealed that the significant predictors
of a change in QoL score were pre-operative QoL score (p <
0.001)
and gender (p = 0.04). The lower the pre-operative score, the higher
the gain in QoL post-operatively (ρ = -0.66; p <
0.001). One
year after surgery the QoL scores in the 612 patients had improved
in 469 (76.6%), remained unchanged in 88 (14.4%) and had deteriorated
in 55 (9.0%).
Traumatic posterior dislocation of the hip associated with a fracture of the posterior acetabular wall and of the neck of the femur is a rare injury. A 29-year-old man presented at a level 1 trauma centre with a locked posterior dislocation of the right hip, with fractures of the femoral neck and the posterior wall of the acetabulum after a bicycle accident. An attempted closed reduction had failed. This case report describes in detail the surgical management and the clinical and radiological outcome. Open reduction and fixation with preservation of the intact retinaculum was undertaken within five hours of injury with surgical dislocation of the hip and a trochanteric osteotomy. Two years after operation the function of the injured hip was good. Plain radiographs and MR scans showed early signs of osteoarthritis with some loss of joint space but no evidence of avascular necrosis. The patient had begun skiing and hiking again. The combination of fractures of the neck of the femur and of the posterior wall of the acetabulum hampers closed reduction of a posterior dislocation of the hip. Surgical dislocation of the hip with trochanteric flip osteotomy allows controlled open reduction of the fractures, with inspection of the hip joint and preservation of the vascular supply.
Given the growing prevalence of obesity around
the world and its association with osteoarthritis of the knee, orthopaedic
surgeons need to be familiar with the management of the obese patient
with degenerative knee pain. The precise mechanism by which obesity
leads to osteoarthritis remains unknown, but is likely to be due
to a combination of mechanical, humoral and genetic factors. Weight loss has clear medical benefits for the obese patient
and seems to be a logical way of relieving joint pain associated
with degenerative arthritis. There are a variety of ways in which
this may be done including diet and exercise, and treatment with
drugs and bariatric surgery. Whether substantial weight loss can
delay or even reverse the symptoms associated with osteoarthritis
remains to be seen. Surgery for osteoarthritis in the obese patient can be technically
more challenging and carries a risk of additional complications.
Substantial weight loss before undertaking total knee replacement
is advisable. More prospective studies that evaluate the effect
of significant weight loss on the evolution of symptomatic osteoarthritis
of the knee are needed so that orthopaedic surgeons can treat this
patient group appropriately.
Narrowing of the femoral neck after resurfacing arthroplasty of the hip has been described previously in both cemented and uncemented hip resurfacing. The natural history of narrowing of the femoral neck is unknown. We retrospectively measured the diameter of the femoral neck in a series of 163 Birmingham hip resurfacings in 163 patients up to a maximum of six years after operation to determine the extent and progression of narrowing. There were 105 men and 58 women with a mean age of 52 years (18 to 82). At a mean follow-up of five years, the mean Harris hip score was 94.8 (47 to 100) and the mean flexion of the hip 112.5° (80° to 160°). There was some narrowing of the femoral neck in 77% (125) of the patients reviewed, and in 27.6% (45) the narrowing exceeded 10% of the diameter of the neck. A multiple logistic regression analysis showed a significant association (chi-squared test (derived from logistic regression) p = 0.01) of narrowing with female gender and a valgus femoral neck/shaft angle. There was no significant association between the range of movement, position or size of the component or radiological lucent lines and narrowing of the neck (chi-squared test; p = 0.10 (flexion), p = 0.08 (size of femoral component), p = 0.09 (size of acetabular component), p = 0.71 (femoral component angulation), p = 0.99 (lucent lines)). There was no significant difference between the diameter of the neck at a mean of three years (2.5 to 3.5) and that at five years (4.5 to 5.5), indicating that any change in the diameter of the neck had stabilised by three years (sign rank test, p = 0.60). We conclude that narrowing of the femoral neck which is found with the Birmingham hip resurfacing arthroplasty is in most cases associated with no adverse clinical or radiological outcome up to a maximum of six years after the initial operation.
We describe the experience with the first consecutive 230 Birmingham hip resurfacings at our centre. At a mean follow-up of three years (25 to 52 months) survivorship was 99.14% with revision in one patient for a loose acetabular component and one death from unrelated causes. One patient developed a fracture of the femoral neck at six weeks which united unremarkably after a period of non-weight-bearing. The Harris hip score improved from a mean of 62.54 (8 to 92) to 97.74 (61 to 100). The mean flexion improved from 91.52° (25 to 140) to 110.41° (80 to 145). Most patients (97%) considered the outcome to be good or excellent. Our preliminary experience with this implant is encouraging and the results are superior to the earlier generation of resurfacings for the same length of follow-up.
We report an independent prospective review of the first 230 Birmingham hip resurfacings in 212 patients at a mean follow-up of five years (4 to 6). Two patients, one with a loose acetabular component and the other with suspected avascular necrosis of the femoral head, underwent revision. There were two deaths from unrelated causes and one patient was lost to follow-up. The survivorship with the worst-case scenario was 97.8% (95% confidence interval 95.8 to 99.5). The mean Harris hip score improved significantly (paired On radiological review at five years, one patient had a progressive lucent line around the acetabular component and six had progressive lucent lines around the femoral component. A total of 18 femoral components (8%) had migrated into varus and those with lucent lines present migrated a mean of 3.8° (1.02° to 6.54°) more than the rest. Superolateral notching of the femoral neck and reactive sclerosis at the tip of the peg of the femoral component were associated with the presence of lucent lines (chi-squared test, p <
0.05), but not with migration of the femoral component, and are of unknown significance. Our results with the Birmingham hip resurfacing continue to be satisfactory at a mean follow-up of five years.
