Between 1990 and 2001, 16 well-fixed, aseptic, primary total knee arthroplasties were revised in 15 patients for a diagnosis of stiffness. Patients were followed for a mean of 42 months (range, 2-6 years). Of 15 patients, 10 (66%) were satisfied with the results of the procedure. The mean Knee Society pain score improved from 28 to 65 points, and the mean functional score improved from 45 to 58 points. The mean arc of motion improved from 40 degrees preoperatively to 73 degrees postoperatively. Recurrent stiffness required additional intervention in 4 knees (3 patients, 25%). The results of revision of a well-fixed, stiff, primary total knee arthroplasty were mixed in our hands and provided only modest improvements in pain, function, and arc of motion. Key words: knee, arthroplasty, stiffness, revision, arthrofibrosis.
1990年至2001年间，15例患者的16例固定良好、无菌的初次全膝关节置换术因僵硬诊断而进行翻修。对患者平均随访42个月（范围为2至6年）。15例患者中，10例（66%）对手术结果满意。膝关节协会疼痛评分平均从28分提高到65分，功能评分平均从45分提高到58分。平均活动弧度从术前的40度提高到术后的73度。4例膝关节（3例患者，25%）出现复发性僵硬需要额外干预。在我们手中，固定良好、僵硬的初次全膝关节置换术翻修的结果参差不齐，仅在疼痛、功能和活动弧度方面有适度改善。关键词：膝关节、关节成形术、僵硬、翻修、关节纤维性变
