Objective: To evaluate the effect of promoting knee joint rehabilitation after total knee arthroplasty (TKA) with a rehabilitation training instrument NEO-GAIT. Methods: Sixty patients who received TKA from January 2017 to July 2017 in the Third Hospital of Hebei Medical University were randomly assigned to receive rehabilitation training with continuous passive motion (CPM) or NEO-GAIT with random number (30 cases in CPM group, included 8 males and 22 females; 30 cases in NEO-GAIT group, included 6 males and 24 females). The visual analogue scale (VAS) evaluation of pain, the postoperative range of motion (ROM) of the knee at the 5th and 10th day, and the Hospital for Special Surgery Knee-rating Score (HSS) at 1-month and 3-month follow-up were recorded. The data were compared between the two groups with paired t test. Results: All the patients were followed-up for more than 3 months. The mean VAS in CPM group and NEO-GAIT group on the 5th day was 2.4±1.1, 2.8±1.3, respectively; and it was 2.1±1.1, 2.5±1.2 respectively on the 10th day after the operation (t=-1.618, -1.505, both P>0.05). There was no significant difference in ROM on the 5th day after operation between the 2 groups (84°±12° vs 85°±12°, t=-0.377, P>0.05); however, it was remarkably higher in the NEO-GAIT group (95°±11°) than that in CPM group (88°±8°) on the 10th day after the operation (t=-3.002, P<0.05). The HSS score at 1-month follow-up in CPM group was 72±9, and it was 84±10 in NEO-GAIT group (t=-5.358, P<0.05); but it was comparative between the two groups at the 3-month follow-up (87±5 vs 89±5, t=-1.575, P>0.05). Conclusion: NEO-GAIT plays a more active and effective role in promoting postoperative rehabilitation after TKA than CPM.
目的： 对比分析全膝关节置换术(TKA)后连续被动运动(CPM)与康复锻炼仪(NEO－GAIT)促进膝关节康复的疗效。 方法： 选取2017年1至7月在河北医科大学第三医院行TKA的患者，应用随机数字表法将患者分为2组，分别使用CPM及NEO－GAIT进行术后康复锻炼。其中CPM组30例，男8例，女22例；NEO－GAIT组30例，男6例，女24例。纪录比较两组术后第5、10天的疼痛视觉模拟评分(VAS)评分、膝关节活动度(ROM)和术后1个月、3个月时的纽约特种外科医院膝关节评分(HSS评分)。组间数据比较采用配对t检验。 结果： 60例患者均获得随访。CPM组、NEO－GAIT组患者术后第5天的VAS分别为(2.4±1.1)、(2.8±1.3)分，差异无统计学意义(t＝－1.618，P>0.05)；术后第10天分别为(2.1±1.1)、(2.5±1.2)分，差异亦无统计学意义(t＝－1.505，P>0.05)。术后第5天，CPM组、NEO－GAIT组膝关节ROM分别为(84±12)°、(85±12)°，差异无统计学意义(t＝－0.377，P>0.05)；术后第10天，2组患者的ROM分别为(88±8)°、(95±11)°，差异有统计学意义(t＝－3.002，P<0.05)。CPM组、NEO－GAIT组患者术后1个月的HSS评分差异有统计学意义[(72±9)比(84±10)分，t＝－5.358，P<0.05]，术后3个月的HSS评分差异无统计学意义[(87±5)比(89±5)分，t＝－1.575，P>0.05]。 结论： 与CPM比较，NEO－GAIT促进TKA术后患者康复具有更积极有效的作用。.
