The results of total knee replacement with a semiconstrained prosthesis after patellectomy are poor because the stabilizing effect of the patella is lost. A series of bicompartmental unicompartmental knee replacements (five patients) carried out for this condition was compared with a series of Insall-Burstein posterior stabilized knee prostheses (six patients). If both cruciate ligaments are present the results are not notably different, but those with an Insall-Burstein prosthesis generally fared better at stair-climbing using the replaced side as the lead leg. Since the Insall-Burstein knee is technically easier to implant there seems little to recommend the bicompartmental unicompartmental prosthesis in this condition.
髌骨切除术后采用半限制性假体进行全膝关节置换的效果不佳，因为髌骨的稳定作用丧失。对针对这种情况进行的一系列双间室单间室膝关节置换术（5例患者）与一系列Insall-Burstein后稳定型膝关节假体（6例患者）进行了比较。如果两条交叉韧带都存在，结果没有明显差异，但使用Insall-Burstein假体的患者在以置换侧作为主导腿上楼梯时总体表现更好。由于Insall-Burstein膝关节在技术上更容易植入，在这种情况下似乎没有什么理由推荐双间室单间室假体。
