We compared patient-reported outcomes of the Kinemax fixed- and mobile-bearing total knee replacement in a multi-centre randomised controlled trial. Patients were randomised to the fixed- or the mobile-bearing prosthesis via a sealed envelope method after the bone cuts had been made in the operating theatre. Randomisation was stratified by centre and(More)
BACKGROUND Several studies have described equivalent performance on radiostereometric analysis at two years for metal-backed compared with all-polyethylene stemmed tibial implants. The purpose of this study was to determine the ten-year survivorship results of these two designs from a large randomized controlled trial. METHODS Patients who were fifty(More)
BACKGROUND The number of patients presenting for total knee replacement who are classified as obese is increasing. The functional benefits of performing TKR in these patients are unclear. AIM To assess the influence pre-operative body mass index has upon knee specific function, general health status and patient satisfaction at 3 years following total knee(More)
This study attempts to quantify the influence of constraint and various indications upon functional outcome following aseptic first-time revision knee arthroplasty. A single-centre prospective study was performed to examine the outcome for 175 consecutive total revision knee replacements performed between 2003 and 2008 with a minimum follow-up of 2 years.(More)
BACKGROUND There is little literature on patient-reported outcomes following total ankle replacement in patients with osteoarthritis, posttraumatic osteoarthritis, and rheumatoid arthritis. We compared the differences in demographic data and clinical and patient-reported outcomes among patients with those types of arthritis who underwent total ankle(More)
OBJECTIVE To describe the baseline clinical and functional characteristics of an international cohort of 193 patients with dysferlinopathy. METHODS The Clinical Outcome Study for dysferlinopathy (COS) is an international multicenter study of this disease, evaluating patients with genetically confirmed dysferlinopathy over 3 years. We present a(More)
BACKGROUND The best timing for patient visits after revision TKA is unclear. Predictors of pain and function reported in the literature typically look at the influence at a given time that might not be ideal if the score is not at a peak or the earliest possible time. Moreover, most reports of predictors include revisions for infection, which typically have(More)
