Unicompartmental arthroplasty for selected cases of anteromedial osteoarthritis of the knee has many potential advantages over total knee replacement. These include a faster postoperative rehabilitation, better range of motion and more physiological function. Aim of this study was to determine clinical and radiological results of Oxford III Unicompartmental knee replacement performed with a short medial incision.

Between October 2002 and December 2004, unicompartmental arthroplasty with Oxford III was performed in 31 knees in 29 patients with symptomatic anteromedial osteoarthritis. All patients were examined clinically and radiologically. The American Knee Society Score was assesed pre- and postoperatively.

At 1 year and 6 months mean follow-up (5 - 30 months) the average AKS Score improved from 62 to 91. 48% of the patients were pleased, 48% satisfied and 4% not satisfied. The postoperative mean range of motion was 131° (120° - 140°). Radiologically, no dislocation or loosening of the components was observed. 2 deep vein thrombosis occurred, 1 prothesis was revised for tibial fracture in a patient with a inflammatory arthritis.

Oxford III Unicompartmental knee replacement can be implanted reliably with a minimally invasive approach. If patients are selected appropriately, this implant reduces postoperative morbidity and complications and provides good clinical results.
