全膝置换后早期持续主动功能锻炼有利于关节功能的恢复

背景：人工全膝关节置换后早期进行康复功能锻炼，可以最大限度改善膝关节功能。 目的：观察主动和被动功能锻炼对全膝置换后早期关节功能恢复的影响。 方法：将226例全膝关节置换患者随机分为2组，置换后分别使用可控主动运动夹板和持续性被动运动器进行关节功能康复，置换后1.5，3，6个月记录两组关节活动度、术后疼痛目测类比VAS评分及KSS功能评分。 结果与结论：置换后3个月可控主动运动组KSS功能评分优于持续性被动运动组，置换后6个月两组间KSS功能评分差异无显著性意义；置换后1.5，3个月可控主动运动组关节活动度优于持续性被动运动组，置换后6个月两组间差异无显著性意义。提示全膝关节置换后使用可控主动运动夹板进行功能训练，可以促进膝关节功能早期恢复。

Controlled active motion and continuous passive motion are beneficial to function rehabilitation after total knee arthroplasty

BACKGROUND:Early rehabilitation training can improve the knee function to maximal extent after total knee arthroplasty (TKA). OBJECTIVE:To acknowledge the difference between controlled active motion and continuous passive motion effects on function rehabilitation after TKA. METHODS:226 patients who underwent unilateral TKA were divided randomly into controlled active motion group and continuous passive motion group. Patient’s general condition, range of motion (ROM), visual analogue scale (VAS) score, knee society score (KSS) function score were recorded at 1.5, 3, 6 months postoperatively. RESULTS AND CONCLUSION:At 3 months postoperatively, the KSS score in the controlled active motion group was superior to that in the continuous passive motion group; at 6 months postoperatively, there was no significant difference in the KSS score between the two groups. At 1.5 and 3 months after TKA, the ROM in the controlled active motion group was better than that in the continuous passive motion group; while, at 6 months, no significant difference was shown between the two groups. Controlled active motion can promote the function rehabilitation after TKA.
