Total knee arthroplasty (TKA) is very effective in relieving pain and improving function in patients with advanced hemophilic arthropathy. Because of intra-articular fibrosis and extra-articular muscle contracture, the gain in motion after TKA has been unsatisfactory. The purpose of this study is to report the results of TKA in patients with hemophilia using posterior cruciate ligament (PCL)-sacrificing prostheses. From April 1987 to May 1998, 9 patients underwent 14 PCL-sacrificing TKAs for advanced hemophilic arthropathy. The average length of follow-up evaluation in surviving patients (13 knees) was 77 months (range, 25-159). A statistically significant difference was found between the preoperative and postoperative values with respect to pain score (5 vs 48), functional score (42 vs 78), flexion deformity (17 degrees vs 5 degrees ), and flexion range (56 degrees vs 81 degrees ). Nine complications occurred in 6 knees. One patient died from HIV-related complications, and none of the patients seroconverted to HIV during the follow-up period.
全膝关节置换术（TKA）对于缓解晚期血友病性关节病患者的疼痛及改善功能非常有效。由于关节内纤维化和关节外肌肉挛缩，TKA术后活动度的改善并不理想。本研究的目的是报告使用后交叉韧带（PCL）牺牲型假体对血友病患者行TKA的结果。1987年4月至1998年5月，9例患者因晚期血友病性关节病接受了14次PCL牺牲型TKA。存活患者（13膝）的平均随访评估时间为77个月（范围25 - 159个月）。术前和术后在疼痛评分（5分对48分）、功能评分（42分对78分）、屈曲畸形（17°对5°）和屈曲范围（56°对81°）方面存在统计学显著差异。6膝出现了9种并发症。1例患者死于HIV相关并发症，随访期间无患者血清转化为HIV阳性。
