Summary

UKA is both a beneficial and cost-effective procedure when performed in appropriate patient populations. Recent studies have shown that the traditional indications for UKA can be expanded with excellent results obtained. There is ongoing debate on the optimal implant (MB versus FB) for UKA with advantages and disadvantages associated with each design type. Although conversion to TKA may not have outcomes equal to that of primary TKA, it has shown to have lower morbidity than revision TKA. Survivorship data should continue to be scrutinized and take both patient factors and functional outcomes into careful consideration. As more long-term data on UKA become available, it will further guide clinicians in counseling patients on whether UKA should be performed.
