We compared the results of total knee arthroplasties in patients with stiff or ankylosed knees. We retrospectively reviewed 90 total knee arthroplasties in 52 patients with minimum 2 years followup who had less than a 50 degrees arc of flexion preoperatively. Preoperative and intraoperative data were retrieved from a computerized database. Patients were followed for an average of 6.5 years at an outpatient department. Knee Society knee scores improved from 34.6 points preoperatively to 89.5 points postoperatively in the stiff knees and from 47 points preoperatively to 75 points postoperatively in the ankylosed knees. The arc of flexion improved from 35 degrees -69 degrees preoperatively to 1 degrees -94 degrees postoperatively in the stiff knees and from 0 degrees to 3 degrees -77 degrees in the ankylosed knees. There were major complications in four of the 26 ankylosed knees and in two of the 64 stiff knees. The data suggest results of total knee arthroplasty are better in patients with stiff knees than in patients with ankylosed knees.
我们比较了膝关节僵硬或强直患者全膝关节置换术的结果。我们回顾性分析了52例患者的90例全膝关节置换术，这些患者均至少随访2年，术前屈曲弧度小于50度。术前和术中数据从计算机数据库中获取。患者在门诊平均随访6.5年。僵硬膝关节患者的膝关节协会膝关节评分从术前的34.6分提高到术后的89.5分，强直膝关节患者的评分从术前的47分提高到术后的75分。僵硬膝关节患者的屈曲弧度从术前的35度 - 69度改善到术后的1度 - 94度，强直膝关节患者的屈曲弧度从0度改善到3度 - 77度。26例强直膝关节患者中有4例出现严重并发症，64例僵硬膝关节患者中有2例出现严重并发症。数据表明，僵硬膝关节患者全膝关节置换术的结果优于强直膝关节患者。
