内镜下膝关节前交叉韧带重建术后下床训练时间窗的研究

目的探讨内镜下膝关节前交叉韧带重建关节功能恢复最佳的下床训练时间窗。方法选取2017年5月至2019年5月于本院行内镜下膝关节前交叉韧带重建术的90例患者为研究对象,按照数字表法随机将其等分为A,B,C 3组,由同一组医护人员行内镜下膝关节前交叉韧带重建术,分别于术后第3天(A组)、第5天(B组)和第7天(C组)下床训练,比较不同时间点3组膝关节功能评分、屈伸活动度及膝关节功能合格率。结果术前3组膝关节功能评分、屈伸活动度比较差异无统计学意义(P>0.05);出院时及出院1个月时B组膝关节功能评分及屈伸活动度均优于A,C组(P<0.05)。结论术后第五天给予行内镜下膝关节前交叉韧带重建术下床训练有利于优化膝关节功能,改善屈伸活动度,提高膝关节功能,有利于加速膝关节恢复。

Study on the time window of out-of-bed training after reconstruction of anterior cruciate ligament of knee-joint under endoscope

Objective To explore the optimal time window of out-of-bed training for reconstructing the joint function of the anterior cruciate ligament(ACL)of knee-joint under endoscope.Methods We selected 90 cases of patients who underwent endoscopic ACL reconstruction in our hospital from May 2017 to May 2019 as the study subjects.They were randomly divided into 3 groups including A,B,and C according to the digital table method,the medical staff of the same group performed endoscopic reconstruction of ACL of knee-joint,and got out-of-bed training on the 3rd day for group A,5th day for group B and 7th day for group C to compare the scores of knee-joint function,flexion and extension active degree,and qualification rates of knee-joint function of the three groups at different time points.Results Before the surgery,there was no significant difference in scores of knee-joint function and flexion and extension active degree between the three groups(P>0.05).The scores of knee-joint function and flexion and extension active degree of group B were better than those of group A and C at discharge and 1 month after discharge(P<0.05).Conclusion On the fifth day after surgery,the application of out-of-bed training after reconstruction of ACL of knee-joint under endoscope was helpful for optimizing knee-joint function,improving flexion and extension active degree,improving knee-joint function,and accelerating knee recovery.
