Mucoid degeneration of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) with osteoarthritis is rarely reported. We experienced two knee osteoarthritic patients who had symptomatic mucoid degeneration of their ACL, and their PCL was also diagnosed as mucoid degeneration in histological evaluation. Preoperative radiological evaluation could not reveal precisely whether the degeneration had extended to the PCL. We obtained good clinical results treating them with posterior-stabilized (PS) total knee arthroplasty (TKA) sacrificing both ligaments. In cases of osteoarthritis with mucoid degenerated ACL, PS TKA should be considered, sacrificing both cruciate ligaments, because mucoid degeneration might expand both cruciate ligaments.
前交叉韧带（ACL）和后交叉韧带（PCL）黏液样变性合并骨关节炎的情况鲜有报道。我们遇到了两名膝关节骨关节炎患者，他们的ACL出现了有症状的黏液样变性，并且在组织学评估中其PCL也被诊断为黏液样变性。术前影像学评估无法准确显示变性是否已扩展至PCL。我们采用牺牲两条韧带的后稳定型（PS）全膝关节置换术（TKA）对他们进行治疗，取得了良好的临床效果。对于伴有ACL黏液样变性的骨关节炎病例，应考虑采用牺牲两条交叉韧带的PS TKA，因为黏液样变性可能会累及两条交叉韧带。
