Comparing Effects of ACL Reconstruction Using Peroneus Longus and Hamstring Tendon Grafts on Ankle Joint Strength and Balance in Patients with ACL Tear

What this Trial Is About

Anterior cruciate ligament ACL injuries are common, especially among young adults and women, and contribute significantly to knee instability. This research investigates the effects of ACL reconstruction using two different tendon graftsthe Peroneus longus tendon PLT autograft and the Hamstring tendon HT autografton the biomechanical properties of the ankle joint complex. The study aims to understand how these grafts influence ankle stability and postural control after surgery, given concerns that PLT grafts might affect ankle proprioception and balance due to their donor site in the ankle. Participants undergo ACL reconstruction with either a PLT or HT autograft. The study measures outcomes using isokinetic dynamometer tests to assess peak torques of ankle plantarflexors and evertors. Functional balance is evaluated through the modified Star Excursion Balance Test and the Single Leg Stance test. These assessments are conducted preoperatively, and then repeated at three and six months post-surgery to compare the effects of the two graft types on ankle strength and balance. Throughout the study, participants are closely monitored for changes in ankle strength and stability. Researchers collect data on peak torque, balance test performance, and single-leg stance duration at three time points. The study uses a randomized design with single masking to ensure objective evaluation. Participants are between 15 and 45 years old with isolated ACL tears and healthy ankles before surgery. The total duration of follow-up is six months after surgery, allowing comparison of recovery and biomechanical outcomes between the two graft methods.
