To investigate the clinical effects of total knee arthroplasty in treatment of ankylosed knee caused by various reasons.
Four patients with 7 ankylosed knees, caused by ankylosing spondylitis in 1 case, septic arthritis with bony ankylosis in 1 case, and rheumatoid arthritis in 2 cases, underwent artificial knee replacement. Before the operation joint activity was 0 degrees , Knee Society score (KSS) was 42 (11 - 63), and the function score was 17. Follow-up was conducted for 5 - 27 months.
Follow-up showed that the average joint activity was raised to 83 degrees (60 degrees - 110 degrees ), KSS score to 83 (64 - 91) points, and function score to 77 points. No infectious case was found.
Total knee arthroplasty has a satisfactory effect in treatment of ankylosed knee. Computer assisted navigation system is helpful in femoro-tibial osteotomy and soft tissue balance. Individualized and directed rehabilitation is a pivotal factor.
探讨全膝关节置换术治疗各种原因所致膝关节强直的临床效果。
4例患者共7个膝关节强直，其中强直性脊柱炎1例，化脓性关节炎致骨性强直1例，类风湿关节炎2例，均行人工膝关节置换术。术前关节活动度为0°，膝关节协会评分（KSS）为42分（11 - 63分），功能评分为17分。随访5 - 27个月。
随访结果显示，平均关节活动度提高到83°（60° - 110°），KSS评分提高到83分（64 - 91分），功能评分为77分。未发现感染病例。
全膝关节置换术治疗膝关节强直效果满意。计算机辅助导航系统有助于股骨 - 胫骨截骨和软组织平衡。个体化、有针对性的康复是关键因素。
