Primary outcomePrimary: Anterior Cruciate Ligament Quality of Life (ACL-QOL) Outcome — 27.0; 29.8; 28.7; 47.7 Score (0 to 100) — p=<0.05
Summary
The purpose of this randomized clinical trial is to determine the difference in quality of life outcome at two years, in patients undergoing an Anterior Cruciate Ligament (ACL) reconstruction procedure with either a patellar tendon, quadruple hamstring tendon or a double-bundle hamstring tendon autograft.

Eligibility Criteria
Inclusion Criteria
A confirmed diagnosis of anterior cruciate ligament deficiency based on all of the following:
- History of a traumatic injury episode
- Physical examination findings of increased anterior translation of the tibia on the femur (Lachman test and/or anterior drawer test)
- A positive pivot shift test
- X-rays showing skeletal maturity (ie: tibial tubercle fused) and no fractures. (NB: Magnetic resonance imaging is not required)
- Age 14-50 years old
Exclusion Criteria
- Patients with combined ligament deficiencies (Posterior Cruciate, Medial and/or Lateral Collateral deficiency.) (NB: Grade 1 side to side differences (ie. 1 cm ² [61]
- Previous ligament surgery on the affected or contralateral knees
- Cases involving litigation or Worker's Compensation
- Confirmed connective tissue disorder (ie: Ehlers-Danlos, Marfans)
- X-ray showing that tibial physis is not fused
