Early Rehabilitationin in Tibial Spine Avulsion Fracture Managed With Arthoscopic Fibre Wire Fixation

Tibial spine avulsion fracture is a common knee injury in adolescents and young adults, often caused by sports trauma or falls. It involves avulsion of the anterior cruciate ligament (ACL) attachment from the tibial eminence and may lead to pain, restricted range of motion, instability, and long-term functional limitations. Arthroscopic fixation using fiber wire is a widely accepted surgical technique for restoring joint stability. However, there is ongoing debate regarding the optimal timing of postoperative rehabilitation. Traditionally, delayed rehabilitation protocols have been used to protect the surgical repair, but prolonged immobilization may lead to joint stiffness, quadriceps atrophy, delayed recovery, and prolonged return to sports. Early rehabilitation protocols aim to initiate controlled mobilization soon after surgery to enhance recovery of knee range of motion, muscle strength, and functional performance while maintaining surgical stability. This randomized clinical trial will compare the effectiveness of early rehabilitation versus conventional (delayed) rehabilitation in patients aged 15-25 years who undergo arthroscopic fiber wire fixation for tibial spine avulsion fracture. Outcomes including knee range of motion (measured using a goniometer), muscle strength (measured using a hand-held dynamometer), and functional disability (assessed using the International Knee Documentation Committee (IKDC) Score) will be evaluated at baseline, 6 weeks, and 12 weeks postoperatively. The findings of this study may help establish evidence-based rehabilitation guidelines and determine whether early rehabilitation provides superior functional outcomes compared to conventional therapy following tibial spine fixation.
