Abstract:
Objective:To investigate the early clinical effects of home-based mobile health intervention on knee joint function after anterior cruciate ligament (ACL) reconstruction.Methods:This was a prospective randomized controlled trial. Patients undergoing arthroscopic ACL reconstruction alone at the Institute of Sports Medicine, Peking University Third Hospital from April 2019 to December 2019 were elected in the trial. Patients were divided into the intervention group and the control group according to random number method. The control group only received the guidance of the traditional paper rehabilitation schedule, while the intervention group also received personalized guidance of electronic rehabilitation prescription and follow-up notice delivered by a WeChat Mini Program Rehabilitation Cloud Platform in addition to the traditional guidance. Joint range of motion (ROM), visual analogue scale (VAS) and thigh circumference difference were assessed before and after the operation. Independent sample t test or Mann-Whitney U test was used for comparison of data between groups, and chi-square test was used for comparison of enumeration data. Results:One hundred and twenty five patients were enrolled in the trial, including 99 males and 26 females, with an average age of 29.0 years (range:18 to 45 years) and an average body mass index of 24.8 kg/m 2 (range:15.8 to 36.6 kg/m 2). At 6 weeks, follow-up was available in 106 cases the target-reach rate of ROM in control group was 42.6%(23/54), which was 67.3%(35/52) in the intervention group, the difference was statistically significant (χ 2=6.53, P=0.01); VAS of the intervention group was 2.5(2.0), lower than that of the control group 3.0(2.0)( M( Q R)), the difference was statistically significant ( Z=-2.06, P=0.04); And the thigh circumference difference of the intervention group was 2.0(2.0)cm lower than that of the control group 3.0(1.8)cm, the difference was statistically significant ( Z=-3.00, P<0.01). Conclusion:Mobile health intervention can improve the early postoperative rehabilitation effect after ACL construction and the ROM of the knee joint, and reduce the bent-knee pain along with the thigh circumference difference.
