Unicompartmental Knee Replacement With New Oxford Instruments

The Oxford unicompartmental knee arthroplasty was developed for the treatment of anteromedial osteoarthritis of the knee. Following strict adherence to the clinical indications, this mobile-bearing device has shown >90% survivorship at 20 years and good to excellent clinical results after 10 years. The addition of small incision surgery to the Oxford technique along with rapid recovery protocols has resulted in quicker functional recovery with less morbidity and mortality, thus making the procedure truly minimally invasive compared with total knee replacement. The most recent evolutionary change to the Oxford technique has been the addition of new instrumentation (Oxford Microplasty) that allows for more reproducible execution of the operation, which might improve the long-term success of the surgery. This article outlines the Oxford surgical technique using the Oxford Microplasty instruments.
