Abstract:
Objective:To observe the effect of early weightbearing after anterior cruciate ligament reconstruction (ACLR) on lower limb motor function, activation of the knee muscles and the stability of the knee joint.Methods:Forty-four persons who had received ACLR were divided at random into a control group and an experiment group, each of 22. In addition to conventional rehabilitation treatment after surgery, the control group underwent weightbearing training from the 8th day after the surgery, while the experimental group began weight-bearing training from the 3rd postoperative day. Both groups had their motor functioning evaluated using the International Knee Scoring Committee (IKDC) knee subjective evaluation form 3 days after the operation, and then 6 and 12 weeks later. Their pain perceptions were quantified on the same schedule using visual analogue scoring (VAS), and protractor measurements documented active range of motion (AROM). Electromyography (AEMG) of the medial head and rectus femoris muscle was also performed, and the stability of the knee joint was assessed using the KT-1000 test.Results:After the intervention, the average IKDC score, VAS score, knee extension and flexion AROMs, medial quadriceps head AEMG ratio, and rectus femoris muscle AEMG ratio improved to different degrees in the two groups. At 6 weeks the average pain score, knee extension and flexion ranges of motion, quadriceps medial head AEMG ratio, and rectus femoris AEMG ratio of the experimental group were all better than the control group′s averages. At 12 weeks the average IKDC subjective knee function score in the experimental group was also superior.Conclusions:Supplementing conventional rehabilitation with early weight-bearing can significantly improve the recovery from anterior cruciate ligament reconstruction. Beginning on day 3 after the operation gives the best results.
