CPD/CME Points: 1
This is a presentation of a unicompartmental knee replacement (UKR) for a 63 year old man with knee pain secondary to medial femoral condyle avascular necrosis. History, examination and investigations were consistent with localised medial knee pain and a failure of conservative treatment. With sparing of the patellofemoral and lateral compartments the decision was to proceed to UKR. It was established prior to surgery that the patient’s cruciate ligaments were intact and functional. Pre-operative counselling and consent included a potential change to total knee replacement on table if on further inspection of the joint on arthrotomy more widespread disease was present. There is however strong evidence that some patellofemoral wear, especially affecting the medial facet of the patella, does not adversely affect the outcome of medial unicompartmental knee replacement.
