Early Rehabilitationin in Tibial Spine Avulsion Fracture Managed With Arthoscopic Fibre Wire Fixation
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.
Tibial spine avulsion fractures are frequently observed in young individuals following sports injuries or traumatic falls. The injury occurs when the anterior cruciate ligament (ACL) pulls off a fragment of bone from the tibial eminence. Arthroscopic fiber wire fixation is a minimally invasive surgical technique that provides stable fixation and allows for anatomical reduction of the avulsed fragment. Despite surgical advancements, postoperative rehabilitation protocols remain controversial.
Conventional rehabilitation protocols typically emphasize prolonged immobilization and delayed initiation of knee range of motion exercises to protect the fixation. However, immobilization may lead to complications such as arthrofibrosis, quadriceps weakness, delayed neuromuscular recovery, and prolonged return to daily and sports activities. Early rehabilitation protocols propose controlled and progressive mobilization immediately after surgery to promote joint nutrition, prevent muscle atrophy, and enhance functional recovery without compromising surgical healing.
This randomized clinical trial will be conducted at the Department of Orthopedics & Sports Surgery, Jinnah Hospital, Allama Iqbal Medical College, Lahore. Eligible participants aged 15-25 years undergoing arthroscopic fiber wire fixation for tibial spine avulsion fracture will be recruited. After informed consent, participants will be randomly allocated into two groups using the lottery method:
Group A (Experimental Group): Early rehabilitation protocol beginning immediately after surgery, including controlled range of motion exercises, progressive strengthening, proprioceptive training, and gradual weight-bearing progression over 12 weeks.
Group B (Control Group): Conventional rehabilitation protocol with knee immobilization for the first 6 weeks postoperatively, followed by gradual initiation of rehabilitation.
Outcome measures include:
Assessments will be conducted at baseline, at the end of 6 weeks, and at the end of 12 weeks postoperatively.
Data will be analyzed using SPSS version 23. Normality of data will be assessed using Kolmogorov-Smirnov and Shapiro-Wilk tests. Repeated Measures ANOVA or Friedman test will be used for within-group comparisons, while Independent t-test or Mann-Whitney U test will be applied for between-group analysis. A p-value ≤ 0.05 will be considered statistically significant.
This study aims to provide clinical evidence regarding the safety and effectiveness of early rehabilitation following arthroscopic fiber wire fixation of tibial spine avulsion fractures and may contribute to improved postoperative rehabilitation guidelines and patient outcomes.
