Oxford unicompartmental knee arthroplasty for anteromedial osteoarthritis

ABSTRACT

The aim of this study was to assess the early outcome of the Oxford unicompartmental arthroplasty [UCA] using the phase 3 prosthesis when used in well selected patients with anteromedial osteoarthritis [OA]. Over a period of 12 months, 24 patients with anteromedial OA of the knee were operated upon. UCA using the phase 3 Oxford prosthesis was performed. All patients were available for follow up at a minimum period of 24 months postoperatively [PO]. At 2-year follow up, only two patients complained of mild pain in the knee. All patients had a continuous improvement in the range of flexion. The mean fixed flexion deformity was 4 degree and the mean varus was 1 degree. It may be concluded that this implant is an effective treatment for anteromedial OA of the knee when patients are properly selected
