摘要：

背景：对于近期活动衬垫型和固定衬垫型全膝关节置换后患膝关节功能改善情况目前专家意见并不一致。
目的：比较活动衬垫型和固定衬垫型全膝关节置换的近期临床效果。
方法：90例膝关节骨性关节炎患者行全膝关节置换，其中活动衬垫型全膝关节置换43例，固定衬垫型全膝关节置换47例。分析患者膝关节置换前、置换后1，3，6个月及1年时术膝的膝关节评分、疼痛评分、功能评分、髌骨评分和膝关节活动度，两组置换前各指标差异无显著性意义。
结果与结论：全膝关节置换后1，3个月，两组患者的膝关节评分、疼痛评分、功能评分、髌骨评分比较，差异无显著性意义(P > 0.05)；置换后6个月及1年时术膝的膝关节评分、疼痛评分、功能评分、髌骨评分中活动衬垫组较固定衬垫组明显进步(P < 0.05)。说明活动衬垫型和固定衬垫型全膝关节置换后患膝关节功能明显改善，且近期结果显示活动衬垫型效果更令人满意。

Abstract:

BACKGROUND: Recently, there are different opinions for the knee function improvement after fixed-bearing and mobile-bearing total knee arthroplasty.
OBJECTIVE: To compare the clinical outcomes between fixed-bearing and mobile-bearing for total knee arthroplasty.
METHODS: Ninety patients with osteoarthritis were treated by fixed-bearing total knee arthroplasty (n=47) or mobile-bearing total knee arthroplasty (n=43). All the data were analyzed including the total knee score, pain score, patient function score, patellar score and motion of the knee joint before total knee arthroplasty, 1, 3 and 6 months and 1 year after total knee arthroplasty, and there was no significant different before replacement between two groups.
RESULTS AND CONCLUSION: There was no significant difference between the two groups in the total knee score, pain score, patient function score and patellar score at 1 and 3 months after replacement (P > 0.05). After 6 months and 1 year, the total knee score, pain score, patient function score and patellar score in the mobile-bearing group were significantly higher than those in the fixed-bearing group (P < 0.05). It indicates that both mobile-bearing and fixed-bearing total knee arthroplasty can improve the knee function, and recent study found that the effect of mobile-bearing is better than that of fixed-bearing.
