With recent design modifications, proper patient selection, and sound surgical technique, medial unicompartmental knee arthroplasty has demonstrated long-term success in the management of degenerative joint disease. Nevertheless, complications do occur, most often aseptic loosening, tibial fracture, polyethylene wear, bearing dislocation, disease progression, infection, and unexplained pain. Some failures can be managed with retention of the implant, whereas others require revision to total knee arthroplasty (TKA), possibly including augments and stems. Although outcomes of unicompartmental knee arthroplasty may not match those of a primary TKA, they tend to exceed results of revision of a previous TKA.
随着最近的设计改进、正确的患者选择和合理的手术技术，内侧单髁膝关节置换术在退行性关节疾病的治疗中取得了长期的成功。然而，并发症确实会发生，最常见的是无菌性松动、胫骨骨折、聚乙烯磨损、轴承脱位、疾病进展、感染和不明原因的疼痛。一些失败可以通过保留植入物来处理，而另一些则需要进行全膝关节置换术（TKA）的翻修，可能包括增材和柄。虽然单髁膝关节置换术的结果可能不如初次 TKA，但它们往往优于先前 TKA 翻修的结果。
