Thirty-seven patients with unicompartmental osteoarthritis were treated by replacement arthroplasty using the Marmor modular prosthesis and each patient was followed for at least two years. Despite rigid preoperative criteria for the selection of cases, the over-all results were definitely inferior to those seen after either bicompartmental or tricompartmental replacement arthroplasty. Complications included recurrent pain and degeneration of the other compartment, often associated with abrasion of the remaining cartilaginous surfaces caused by polyethylene particles. There was also more settling of the tibial component in these patients than in patients treated by bicompartmental replacement arthroplasty. Because of these findings, we no longer use unicompartmental replacement of the medial side of the knee. The results after the three lateral compartment replacements, on the other hand, were good, and use of this procedure for post-traumatic arthritis is still under investigation.
37例单髁骨关节炎患者接受了使用马莫尔模块化假体的置换关节成形术治疗，且对每位患者至少随访了两年。尽管术前有严格的病例选择标准，但总体结果明显逊于双髁或三髁置换关节成形术后的结果。并发症包括反复疼痛和其他髁间室的退变，常与聚乙烯颗粒导致的剩余软骨表面磨损有关。与接受双髁置换关节成形术治疗的患者相比，这些患者的胫骨部件下沉也更多。基于这些发现，我们不再采用膝关节内侧单髁置换术。另一方面，三次外侧髁间室置换术后的效果良好，该手术用于创伤后关节炎的研究仍在进行中。
