Unicompartmental knee arthroplasty (UKA) is a successful treatment modality in selected patients having advanced, single-compartment osteoarthritis of the knee. The bone and ligament preservation leading to shorter recovery periods, better functional outcomes, lower perioperative complication rates, and easier revision, if needed, are proposed as some of the advantages of UKA over total knee arthroplasty (TKA). Despite several advantages, UKA is reported to have higher failure rates as compared to TKA. The prosthesis failure of UKA is directly correlated to intraoperative technique-related factors like malpositioning of components and the inability to replicate the target-limb alignment as per preoperative planning. An evidence-based surgical technique for UKA may help surgeons to avoid the intraoperative technique-related errors. The purpose of this paper is to describe a stepwise surgical technique for the fixed-bearing medial UKA.
单髁膝关节置换术（UKA）是治疗膝关节晚期单髁骨关节炎患者的一种成功治疗方式。与全膝关节置换术（TKA）相比，UKA具有保留骨骼和韧带、恢复时间短、功能预后更好、围手术期并发症发生率低以及必要时翻修更容易等优点。尽管有诸多优势，但据报道UKA的失败率高于TKA。UKA的假体失败与术中技术相关因素直接相关，如部件位置不当以及无法按照术前规划复制目标肢体对线。基于循证的UKA手术技术可能有助于外科医生避免术中技术相关错误。本文旨在描述固定平台内侧UKA的分步手术技术。
