The case for partial knee replacement
The case for greater use of medial UKA in knee arthroplasty surgery rests on the benefits for patients of faster recovery, less morbidity, less mortality and better functional outcome when compared to TKA. This has been supported by improved longterm results and recognition of the large number of patients who meet the criteria for UKA. Medial UKA should, therefore, be seen as a definitive treatment for medial osteoarthritis and not as a pre-total knee replacement procedure. In a similar way, strong arguments for partial knee replacement in the lateral and patellofemoral joint are also emerging.
