Effect of virtual reality balance training on knee joint function after anteriorcruciate ligament reconstruction

Objective To investigate the effects of virtual reality (VR) balance training combined with routine rehabilitation on postoperative proprioception and knee joint function recovery in patients with anterior cruciate ligament (ACL) reconstruction.

Methods A total of 100 patients after ACL reconstruction were randomly divided into control group (n=50) and observation group(n=50). The control group received routine rehabilitation, and the observation group received VR balance training on the basis of routine rehabilitation. Proprioceptive function (knee angle reappearance difference, detection threshold of passive activity) and knee functionInternational Knee Scoring Committee (IKDC) score, Lysholm score before and after treatment were observed and compared between the two groups.

Results After treatment, the knee angle reconstruction difference and passive activity detection threshold of the two groups were lower compared with those before treatment, and were lower in the observation group than those in the control group (P < 0.05). After treatment, the Lysholin score and IKDC score in the observation group were (76.23±6.49) and (69.12±9.46), respectively, which were significantly higher than (71.41±7.23) and (65.22±9.47) in the control group, and the differences were statistically significant (P < 0.05).

Conclusion VR balance training can improve proprioceptive function of patients after ALC reconstruction and promote the recovery of knee joint function.
