Brief summary
This prospective randomized controlled study compares outcomes of ACL reconstruction using bone-patellar tendon-bone (BPTB) versus hamstring tendon (HT) autografts in professional athletes. The primary outcome is isokinetic muscle strength assessment. Secondary outcomes include IKDC score, return to athletic activity, and complication rates. Patients are followed for five years.
Detailed description
This randomized controlled trial evaluates BPTB versus HT autografts in professional athletes undergoing ACL reconstruction. Patients with isolated ACL rupture were randomly assigned to either graft. All procedures and rehabilitation protocols were standardized. The primary outcome was isokinetic assessment of quadriceps and hamstring strength using a dynamometer. Secondary outcomes included IKDC score, return to sport, and complications. Patients were followed for five years to assess functional recovery and long-term outcomes.
Interventions
PROCEDUREBPTB ACL Reconstruction
Arthroscopic anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft with interference screw fixation.
PROCEDUREHamstring ACL Reconstruction

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Isokinetic Quadriceps and Hamstring Muscle Strength | 12 months postoperatively | Isokinetic dynamometric assessment of quadriceps and hamstring muscle strength expressed as peak torque percentage relative to the contralateral limb using a standardized testing protocol. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| International Knee Documentation Committee (IKDC) Score | 12 months postoperatively | Patient-reported functional outcome measured using the IKDC subjective knee evaluation form. |
| Time to Return to Athletic Activity | Up to 12 months postoperatively | Time required for patients to return to pre-injury level of athletic activity. |
| Postoperative Complications | Up to 60 months postoperatively | Incidence of complications including infection, anterior knee pain, extension lag, stiffness, and graft re-rupture. |
| Knee function using KOOS score | 60 months postoperatively | Patient-reported outcomes assessed using the Knee Injury and Osteoarthritis Outcome Score (KOOS), including subscales: * Pain * Symptoms * Sport and Recreation * Quality of Life Scores reported on a 0-100 scale (higher scores indicate better function). |
