Unicompartmental knee arthroplasty (UKA) was introduced in the early 1970s but did not receive substantial support because total knee arthroplasty was flourishing. In the early 1990s, interest in UKA increased with the introduction of a minimally invasive surgical approach. It is important that the indications for this demanding but achievable surgical technique be strictly observed. The extension and flexion gaps for UKA can be addressed in a similar fashion to total knee arthroplasty and should be equalized. The femoral and tibial components must be properly sized so that the surfaces are well covered without overhang or impingement. UKA results at 10- to 15-year follow-ups are encouraging and are similar to many reported results of total knee arthroplasty.
单髁膝关节置换术（UKA）于20世纪70年代初被引入，但由于全膝关节置换术的蓬勃发展，它并未得到大力支持。在20世纪90年代初，随着微创外科手术方法的引入，人们对UKA的兴趣增加。严格遵守这种要求高但可实现的手术技术的适应症非常重要。UKA的屈伸间隙可以用与全膝关节置换术类似的方式处理，并且应该使其相等。股骨和胫骨组件的尺寸必须合适，以便表面得到良好覆盖，没有悬垂或撞击。UKA在10至15年随访时的结果令人鼓舞，与许多报道的全膝关节置换术结果相似。
