This study compared the results of total knee arthroplasty (TKA) in patients with stiff knees and patients with good preoperative range of motion. Results following TKA were compared in 30 patients (52 knees) with severely degenerated knees with preoperative range of motion < 50 degrees (group 1) and 30 patients (50 knees) who were matched for age, gender, and diagnosis with preoperative range of motion > 90 degrees (group 2). Results were evaluated for range of motion and Knee Society score, as well as the need for extensile approaches, soft-tissue releases, additional bone cuts, and constrained prostheses. Radiographic results were evaluated for implant positioning, patellar height, and alteration in joint line. Findings indicated that although TKA in stiff knees can be successful, the results are inferior to those obtained in standard TKA. Careful preoperative planning and meticulous surgical technique are essential for good results.
本研究比较了膝关节僵硬患者与术前活动范围良好患者的全膝关节置换术（TKA）结果。对30例（52膝）术前活动范围<50度的严重退变膝关节患者（第1组）和30例年龄、性别和诊断相匹配且术前活动范围>90度的患者（第2组，50膝）的TKA术后结果进行了比较。对活动范围、膝关节协会评分以及是否需要采用扩展性入路、软组织松解、额外截骨和限制性假体进行了结果评估。对影像学结果进行了评估，包括植入物位置、髌骨高度和关节线改变。研究结果表明，虽然僵硬膝关节的TKA可以成功，但结果不如标准TKA。仔细的术前规划和细致的手术技术对于取得良好结果至关重要。
