The purpose of our study was three fold; firstly to assess the survival of closing wedge high tibial osteotomies (CWHTO), secondly to assess any clinical factors or radiological alignment which may affect survival and thirdly to assess the change in tibial inclination and patella height. Details of 51 patients undergoing CWHTO for varus gonarthrosis between 1999 and 2007 were assessed for age, BMI, gender, range of movement, meniscal integrity and grade of arthritis. Radiological evaluation included pre and post-operative femoro-tibial axis, tibial slope and patella height. Outcome was also evaluated by Oxford knee score and UCLA activity score. Failure was considered as conversion to arthroplasty.Aims
Methods
The primary aim of this study was to determine the long-term survival of OATS (Osteochondral Autograft Transfer System) (Arthrex, Florida, USA) grafting in our centre and evaluate the reasons for failure, the secondary aim was to ascertain if age, gender, BMI, site or size of OATS graft had any influence on outcome. Details of patients undergoing an OATS procedure from 1999 to 2008 were collected. Loosening, graft degeneration or subsequent surgery in the form of arthroplasty, revision OATS¯ or any other osteochondral procedure was considered as failure. Oxford knee score and UCLA activity score evaluated outcome.Aims
Methods
Unicompartmental knee arthroplasty provides a good alternative to total knee arthroplasty in patients with isolated medial compartment osteoarthritis. There has been variable reporting in the literature as to whether age and sex affect the survival of unicompartmental knee arthroplasty. The aims of this study were to determine whether age and sex were predictors of failure for the Oxford unicompartmental knee arthroplasty.Background
Study aims
A number of studies have reported on the early failure of the Oxford unicompartmental knee arthroplasty. However, less evidence is available regarding the outcome following revision of failed unicompartmental knee prostheses to total knee arthroplasty. The study aims were to determine the time to failure and mode of failure for the Oxford unicompartmental knee arthroplasty and to assess the short-term outcome following revision surgery.Background
