Cause di fallimento delle protesi monocompartimentali di ginocchio

Abstract

Over the past 20 years, there has been an increased use of unicompartmental knee replacement (UKR) for medial osteoarthritis of the knee as an alternative treatment to total knee replacement (TKR). Unicompartmental knee replacement has several advantages over TKR, including better knee kinematics, fewer serious complications and a more cost-effective strategy. However, despite these benefits and improved success rates, joint registries in recent years have shown higher revision rates for patients with UKR than for those with TKR. Unicompartmental knee replacement failure rates are similar to those of TKR, assuming that UKR is performed on appropriately indicated patients and the correct surgical technique is followed.
