新疆医科大 新疆医科大学硕士学位论文 PAGE PAGE 1 固定平台型和旋转平台型假体 TKA 疗效 的随机对照研究 研究生：曾赟 导师：曹力 教授 摘 要 目的：随机对照试验比较固定平台型和旋转平台型假体在人工全膝关节置换术 （TKA）后的早期临床疗效。方法：将 2008 年 10 月至 2009 年 3 月我科诊断为膝关 节骨性关节炎的患者，连续随机分配至固定平台组（A 组 37 例）和旋转平台组（B 组 35 例）行全膝关节表面置换术，记录术前及术后 6 月、1 年、2 年时的膝关节评 分（包括 KSS 膝评分、KSS 功能评分、HSS 评分、WOMAC 骨关节炎评分）、膝关 节活动度（ROM）和术后并发症等指标，进行统计学分析。结果：两组之间各评分 系统和 ROM 在术前及术后 6 月、1 年、2 年随访，差异均无统计学意义（P 0.05）； 两组并发症的比较也无统计学差异：膝关节感染（固定组 0 例，旋转组 1 例，P=0.486）， 翻修（固定组 0 例，旋转组 1 例，P=0.486），脱位（固定组 0 例，旋转组 1 例，P=0.486）， 关节弹响（固定组 1 例，旋转组 3 例，P=0.350），膝前痛（固定组 7 例，旋转组 5 例，P=0.634），不明原因关节弹响（固定组 1 例、旋转组 3 例，P=0.350）。结果显 示两组术后的膝关节评分、活动度和并发症的差异均无统计学意义。结论：固定平 台型和旋转平台型假体 TKA 术后早期临床疗效无明显差异。 关键词： 全膝关节置换术；固定平台假体；活动平台假体；随机对照试验 A randomized controlled trail of early clinical outcomes of fi xed- versus mobile-bearing total knee arthroplasty Postgraduate: Zeng Yun Supervisor: Prof. Cao Li Abstract Objective：Randomized clinical study was to compare the early results of primary total knee arthroplasty using a fixed-bearing and a Mobile-bearing prosthesis. Methods：the patients who have been diagnosed as osteoarthritis in our hospital from October 2008 to March 2009 were sequentially distributed to A group(Using fixed-bearing prosthesis，n=37) and B group(Using mobile-bearing prosthesis，n=35) at random. And record the Knee Society Score(KSS), Hospital for special surgery knee score(HSS), Western Ontario MacMaster (WOMAC)，the range of motion (ROM)，the postoperative complication and etc from the preoperation and afteroperation respectively in six months, one year and two years. Results: There were no significant difference between the two groups at preoperatively and postoperatively in KSS, HSS, WOMAC，ROM and the postoperative complication (P 0.05). As to clinical outcomes, the Fixed-bearing and Mobile-bearing prosthesis have no difference in this study. Conclusions: No significant differences were found in clinical results between the two prostheses. Key words: total knee arthroplasty; fixed-bearing; mo
