Visual-guided balance training to improve knee function after ACL reconstruction

Effect of Visual-Guided Balance Training on Knee Motor Function and Biomechanical Characteristics After ACL Reconstruction

Not applicable Interventional Peking University Third Hospital · NCT07306221

This program tests whether adding visual-guided balance training to standard rehabilitation helps adults 18–45 recover knee function and walking after ACL reconstruction.

What this trial studies

This randomized controlled trial enrolls adults with primary unilateral ACL reconstruction and begins the intervention at week five after surgery. Participants receive standardized rehabilitation and are randomized to either traditional general balance training or visual-guided balance training, while a healthy control group provides baseline comparison. Outcomes include movement-function tests, gait analysis, and biomechanical measurements to quantify knee joint function and walking performance. The trial compares how effectively visual-guided training narrows the functional gap between post-ACLR patients and healthy individuals.

Who should consider this trial

Good fit: Adults aged 18–45 with BMI 18.5–<35 who had primary unilateral ACL reconstruction using an autologous hamstring tendon at Peking University Third Hospital, with no or only minor additional knee ligament or meniscus injury, are ideal candidates.

Not a fit: Patients with reconstruction performed more than one year after injury, significant additional ligament or meniscal tears, prior knee surgery, or those outside the specified age/BMI ranges are unlikely to qualify or benefit.

Why it matters

Potential benefit: If successful, this approach could speed and improve recovery of knee function and gait after ACL reconstruction, helping patients return closer to normal walking and activity levels.

How similar studies have performed: Previous studies of balance and visual-feedback rehabilitation after ACL reconstruction have reported promising but variable improvements in balance and gait, so this approach builds on but does not yet uniformly confirm prior findings.
