We evaluated the 2- to 7-year results of a rotating-hinge knee replacement after excision of malignant tumors of the knee joint. There were 25 distal femoral and 7 proximal tibial replacements. The 5-year prosthetic survival for distal femoral replacements was 88%, compared with 58% for proximal tibial replacements. Seven patients underwent prosthetic exchange: 1 for aseptic loosening, 2 for wound slough and perioperative infection, and 4 for articulating component failure. One patient underwent above-knee amputation owing to skin necrosis. The median functional scores at the latest follow-up were 27 by the International Society of Limb Salvage evaluation system and 80 by the Hospital for Special Surgery Knee Score system. This implant is a promising choice for joint reconstruction after excision of tumors at the knee joint.
我们评估了膝关节恶性肿瘤切除术后旋转铰链膝关节置换术2至7年的结果。其中有25例股骨远端置换和7例胫骨近端置换。股骨远端置换的5年假体生存率为88%，而胫骨近端置换为58%。7例患者进行了假体置换：1例因无菌性松动，2例因伤口溃疡和围手术期感染，4例因关节部件故障。1例患者因皮肤坏死接受了膝上截肢。根据国际肢体保全协会评估系统，最近一次随访时的功能评分中位数为27分，根据特种外科医院膝关节评分系统为80分。这种植入物是膝关节肿瘤切除术后关节重建的一个有前景的选择。
