Study 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.

Read the 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.

What researchers measure

Primary outcomes

  1. Isokinetic Quadriceps and Hamstring Muscle Strength

    Isokinetic dynamometric assessment of quadriceps and hamstring muscle strength expressed as peak torque percentage relative to the contralateral limb using a standardized testing protocol.

    Time frame: 12 months postoperatively

Secondary outcomes

  1. International Knee Documentation Committee (IKDC) Score

    Patient-reported functional outcome measured using the IKDC subjective knee evaluation form.

    Time frame: 12 months postoperatively

  2. Time to Return to Athletic Activity

    Time required for patients to return to pre-injury level of athletic activity.

    Time frame: Up to 12 months postoperatively

  3. Postoperative Complications

    Incidence of complications including infection, anterior knee pain, extension lag, stiffness, and graft re-rupture.

    Time frame: Up to 60 months postoperatively

  4. Knee function using KOOS score

    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).

    Time frame: 60 months postoperatively
