Between January 1985 and December 1987, 100 consecutive metal-backed, unicompartmental arthroplasties (MBUKAs) were performed and retrospectively reviewed; 5 patients died, and the surviving 95 patients were reviewed. Of these arthroplasties, 10 were uncemented and 85 were cemented. There were 2 failures in the uncemented arthroplasties and 10 failures in those that were cemented, resulting in an 87.4% survivorship at a mean follow-up of 10 years. After 5 years, 10 of these cases were revised because of progressive lateral compartment disease and lateral compartment pain. Despite improved function compared with tricompartmental arthroplasty, MBUKA is beneficial only in highly selective cases. In this series, after 5 years, survivorship declined because of progression of arthrosis in the nonreplaced compartment.
1985年1月至1987年12月期间，连续进行了100例金属背衬单髁关节置换术（MBUKA），并进行了回顾性研究；5例患者死亡，对存活的95例患者进行了复查。在这些关节置换术中，10例为非骨水泥型，85例为骨水泥型。非骨水泥型关节置换术有2例失败，骨水泥型有10例失败，平均随访10年时的生存率为87.4%。5年后，其中10例因外侧间室疾病进展和外侧间室疼痛而进行了翻修。尽管与全髁关节置换术相比功能有所改善，但MBUKA仅在高度选择性的病例中有益。在本系列中，5年后，由于未置换间室的关节病进展，生存率下降。
