Unicompartmental knee arthroplasty (UKA) has evolved into a suitable option for diseased knees that cannot be managed with arthroscopic treatment and at the same time are not good candidates for total knee replacement. Since meticulous execution of the surgical technique is essential to optimizing UKA outcome, some procedural key-points are mandatory. Templates (phantoms) are then used to size the required prosthetic component (using these radiographs. Arthritic varus (or valgus) knees with an asymptomatic patello-femoral joint are typically ideal for UKA. Metal-backed tibial components should be favourite instead of all-polyethylene tibial components to avoid polyethylene creep that may occur in fixed bearings. Moreover, a proper thickness of the polyethylene layer is mandatory, in order to avoid early failure.
单髁膝关节置换术（UKA）已发展成为一种适用于无法通过关节镜治疗且同时不适合进行全膝关节置换的患病膝关节的选择。由于手术技术的精细执行对于优化UKA的结果至关重要，因此一些手术关键点是必不可少的。然后使用模板（模型）来确定所需假体组件的尺寸（使用这些X线片）。无症状髌股关节的膝内翻（或膝外翻）关节炎膝关节通常是UKA的理想选择。金属背衬的胫骨组件应比全聚乙烯胫骨组件更受青睐，以避免在固定轴承中可能发生的聚乙烯蠕变。此外，聚乙烯层的适当厚度是必不可少的，以避免早期失败。
