The use of trabecular metal (TM) shells supported by augments has provided good mid-term results after revision total hip arthroplasty (THA) in patients with a bony defect of the acetabulum. The aim of this study was to assess the long-term implant survivorship and radiological and clinical outcomes after acetabular revision using this technique. Between 2006 and 2010, 60 patients (62 hips) underwent acetabular revision using a combination of a TM shell and augment. A total of 51 patients (53 hips) had complete follow-up at a minimum of seven years and were included in the study. Of these patients, 15 were men (29.4%) and 36 were women (70.6%). Their mean age at the time of revision THA was 64.6 years (28 to 85). Three patients (5.2%) had a Paprosky IIA defect, 13 (24.5%) had a type IIB defect, six (11.3%) had a type IIC defect, 22 (41.5%) had a type IIIA defect, and nine (17%) had a type IIIB defect. Five patients (9.4%) also had pelvic discontinuity.Aims
Patients and Methods
We performed a meta-analysis investigating the association between preoperative psychological distress and postoperative pain and function after total knee arthroplasty (TKA). Pubmed/Medline, Embase, PsycINFO, and the Cochrane library were searched for studies on the influence of preoperative psychological distress on postoperative pain and physical function after TKA. Two blinded reviewers screened for eligibility and assessed the risk of bias and the quality of evidence. We used random effects models to pool data for the meta-analysis.Aims
Materials and Methods
The primary aim of this study was to compare the knee-specific functional outcome of patellofemoral arthroplasty with total knee arthroplasty (TKA) in the management of patients with patellofemoral osteoarthritis. A total of 54 consecutive Avon patellofemoral arthroplasties were identified and propensity-score-matched to a group of 54 patients undergoing a TKA with patellar resurfacing for patellofemoral osteoarthritis. The Oxford Knee Score (OKS), the 12-Item Short-Form Health Survey (SF-12), and patient satisfaction were collected at a mean follow up of 9.2 years (8 to 15). Survival was defined by revision or intention to revise.Aims
Patients and Methods
Patients with a failed reverse shoulder arthroplasty (RSA) have limited salvage options. The aim of this study was to determine the outcome of revision RSA when used as a salvage procedure for a failed primary RSA. We reviewed all revision RSAs performed for a failed primary RSA between 2006 and 2012, excluding patients with a follow-up of less than two years. A total of 27 revision RSAs were included in the study. The mean age of the patients at the time of revision was 70 years (58 to 82). Of the 27 patients, 14 (52% were female). The mean follow-up was 4.4 years (2 to 10).Aims
Patients and Methods
The objective of this study was to compare early postoperative
functional outcomes and time to hospital discharge between conventional
jig-based total knee arthroplasty (TKA) and robotic-arm assisted
TKA. This prospective cohort study included 40 consecutive patients
undergoing conventional jig-based TKA followed by 40 consecutive
patients receiving robotic-arm assisted TKA. All surgical procedures
were performed by a single surgeon using the medial parapatellar
approach with identical implant designs and standardized postoperative inpatient
rehabilitation. Inpatient functional outcomes and time to hospital
discharge were collected in all study patients.Aims
Patients and Methods
As the population ages, there is projected to be an increase in the level of demand for total knee arthroplasty (TKA) in octogenarians. We aimed to explore whether those aged ≥ 80 years achieved similar improvements in physical function to younger patients while also comparing the rates of length of stay (LOS), discharge to rehabilitation, postoperative complications, and mortality following TKA in older and younger patients. Patients from one institution who underwent primary elective TKA between 1 January 2006 and 31 December 2014 were dichotomized into those ≥ 80 years old (n = 359) and those < 80 years old (n = 2479) for comparison. Multivariable regression was used to compare the physical status component of the 12-Item Short-Form Health Survey (SF-12), LOS, discharge to rehabilitation, complications, and mortality between the two groups.Aims
Patients and Methods
Recent studies of nonoperatively treated displaced midshaft clavicular fractures have shown a high incidence of nonunion and unsatisfactory functional outcome. Some studies have shown superior functional results and higher rates of healing following operative treatment. The aim of this study was to compare the outcome in these patients after nonoperative management with those treated with fixation. In a multicentre, parallel randomized controlled trial, 146 adult patients with an acute displaced fracture of the midthird of the clavicle were randomized to either nonoperative treatment with a sling (71, 55 men and 16 women with a mean age of 39 years, 18 to 60) or fixation with a pre-contoured plate and locking screws (75, 64 men and 11 women with a mean age of 40 years, 18 to 60). Outcome was assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) Score, the Constant Score, and radiographical evidence of union. Patients were followed for one year.Aims
Patients and Methods
The aims of this study were to evaluate the incidence of postoperatively restricted weight-bearing and its association with outcome in patients who undergo surgery for a fracture of the hip. Patient aged > 60 years undergoing surgery for a hip fracture were identified in the 2016 National Surgical Quality Improvement Program (NSQIP) Hip Fracture Targeted Procedure Dataset. Analysis of the effect of restricted weight-bearing on adverse events, delirium, infection, transfusion, length of stay, return to the operating theatre, readmission and mortality within 30 days postoperatively were assessed. Multivariate regression analysis was used to adjust for confounding demographic, comorbid and procedural characteristics.Aims
Patients and Methods
The aim of this study was to report the implant survival and patient-reported outcome measures (PROMs) in a consecutive series of patients aged less than 50 years at the time of arthroplasty using the Birmingham Hip Resurfacing system (BHR), with a minimum follow-up of ten years. A total of 226 patients with osteoarthritis of the hip, who underwent BHR and presented to a single surgeon, were included in the study. Survival of the implant was confirmed by cross-checking with the Australian Orthopaedic Association National Joint Replacement Registry. Kaplan–Meier survival curves with 95% confidence intervals (CIs) were constructed. Pre- and postoperative PROMs were compared with Aims
Patients and Methods
This study reports on the medium- to long-term implant survivorship
and patient-reported outcomes for the Avon patellofemoral joint
(PFJ) arthroplasty. A total of 558 Avon PFJ arthroplasties in 431 patients, with
minimum two-year follow-up, were identified from a prospective database.
Patient-reported outcomes and implant survivorship were analyzed,
with follow-up of up to 18 years.Aims
Patients and Methods
The aims of this study were to review the surgical technique for a combined femoral head reduction osteotomy (FHRO) and periacetabular osteotomy (PAO), and to report the short-term clinical and radiological results of a combined FHRO/PAO for the treatment of selected severe femoral head deformities. Between 2011 and 2016, six female patients were treated with a combined FHRO and PAO. The mean patient age was 13.6 years (12.6 to 15.7). Clinical data, including patient demographics and patient-reported outcome scores, were collected prospectively. Radiologicalally, hip morphology was assessed evaluating the Tönnis angle, the lateral centre to edge angle, the medial offset distance, the extrusion index, and the alpha angle.Aims
Patients and Methods
The aim of this study was to examine the association between
postoperative glycaemic variability and adverse outcomes following
orthopaedic surgery. This retrospective study analyzed data on 12 978 patients (1361
with two operations) who underwent orthopaedic surgery at a single
institution between 2001 and 2017. Patients with a minimum of either
two postoperative measurements of blood glucose levels per day,
or more than three measurements overall, were included in the study.
Glycaemic variability was assessed using a coefficient of variation
(CV). The length of stay (LOS), in-hospital complications, and 90-day
readmission and mortality rates were examined. Data were analyzed
with linear and generalized linear mixed models for linear and binary
outcomes, adjusting for various covariates.Aims
Patients and Methods
The reasons for failure of a hemirthroplasty (HA) when used to
treat a proximal humeral fracture include displaced or necrotic
tuberosities, insufficient metaphyseal bone-stock, and rotator cuff
tears. Reverse total shoulder arthroplasty (rTSA) is often the only
remaining form of treatment in these patients. The aim of this study
was to evaluate the clinical outcome after conversions from a failed
HA to rTSA. A total of 35 patients, in whom a HA, as treatment for a fracture
of the proximal humerus, had failed, underwent conversion to a rTSA.
A total of 28 were available for follow-up at a mean of 61 months
(37 to 91), having been initially reviewed at a mean of 20 months
(12 to 36) postoperatively. Having a convertible design, the humeral
stem could be preserved in nine patients. The stem was removed in
the other 19 patients and a conventional rTSA was implanted. At
final follow-up, patients were assessed using the American Shoulder
and Elbow Surgeons (ASES) score, the Constant Score, and plain radiographs.Aims
Material and Methods
The aims of this study were to compare the mid-term outcomes
of patients with late-stage arthritis of the wrist treated with
proximal row carpectomy (PRC) and dorsal capsular interposition
(DCI) arthroplasty with a matched cohort treated with routine PRC
alone. A total of 25 arthritic wrists (24 patients) with pre-existing
degenerative changes of the proximal capitate and/or the lunate
fossa of the radius were treated with PRC + DCI over a ten-year
period. This group of patients were matched 1:2 with a group of
50 wrists (48 patients) without degenerative changes in the capitate
or lunate fossa that were treated with a routine PRC alone during
the same period. The mean age of the patients at the time of surgery
was 56.8 years (25 to 81), and the demographics and baseline range
of movement of the wrist, grip strength, Quick Disabilities of the
Arm, Shoulder, and Hand (QuickDASH) score, and Patient-Rated Wrist
Evaluation (PRWE) score were similar in both groups. Aims
Patients and Methods
The aims of this study were to investigate any possible relationship
between a preoperative sensitivity to pain and the degree of pain
at rest and on exertion with postoperative function in patients
who underwent stemless total shoulder arthroplasty (TSA). In this prospective study, we included 63 patients who underwent
stemless TSA and were available for evaluation one year postoperatively.
There were 31 women and 32 men; their mean age was 71 years (53
to 89). The pain threshold, which was measured using a Pain Matcher
(PM) unit, the degree of pain (visual analogue scale at rest and
on exertion, and function using the short version of the Disabilities
of the Arm, Shoulder and Hand questionnaire (QuickDASH), were recorded
preoperatively, as well as three and 12 months postoperatively.Aims
