What this Trial Is About
Researchers are evaluating knee joint stability, functional capacity, postural control, muscle activation, and muscle strength in patients with anterior cruciate ligament (ACL) injuries. This study compares two surgical techniques: conventional ACL reconstruction alone and ACL reconstruction combined with anterolateral ligament (ALL) reconstruction. Patients aged 18 to 50 years with unilateral ACL injuries will be included and followed through rehabilitation for up to nine months. Participants will be randomly assigned to one of two groups. Group 1 will undergo conventional ACL reconstruction using quadruple flexor tendons (semitendinosus and gracilis) performed with videoarthroscopy, followed by conventional physiotherapy including manual therapy, physical resources, kinesiotherapy, and isokinetic exercises. Group 2 will receive the same conventional ACL reconstruction plus ALL reconstruction using a similar surgical approach and graft preparation, followed by the same physiotherapy rehabilitation. Both groups will be evaluated before and after surgery. Throughout the study, participants will be assessed on articular range of motion, functional capacity, and isometric muscle strength at preoperative and multiple postoperative timepoints (5, 15, 30, 60, and 120 days). Secondary assessments include gait analysis, functional tests, postural control, and muscle activation measured by surface electromyography at similar intervals. The study is double-blinded and randomized, with ongoing monitoring during rehabilitation to compare outcomes between the two surgical methods.
