NCT00529958

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Anterior Cruciate Ligament Quality of Life (ACL-QOL) Outcome

    The 32-item patient-reported Anterior Cruciate Ligament Quality-of-Life (ACL-QOL) questionnaire assesses symptoms/physical complaints, work-related, sports/recreational, lifestyle and social/emotional concerns. A higher score on the 0 to 100mm visual analog scale represents better quality of life.

    Baseline, 3 and 6 months, 1, 2, and 5 years post-operatively

Secondary Outcomes (11)

  • Number of Participants With Traumatic ACL Re-ruptures and Atraumatic Graft Failures

    Minimum 2-year Follow-up, 5-Year Follow-up, 10-Year Follow-up

  • Number of Participants With Each International Knee Documentation Committee (IKDC) Objective Overall Group Grade

    Baseline, 1, 2, 5 years post-operatively

  • Mean International Knee Documentation Committee (IKDC) Subjective Score

    Baseline, 3 and 6 months, 1, 2 and 5 years post-operatively

  • Number of Participants With Each Pivot Shift Grade

    Baseline, 3 and 6 months, 1, 2 and 5 years post-operatively

  • Proportion of Patients With Moderate or Severe Kneeling Pain

    Baseline, 2 and 5 years post-operatively

  • +6 more secondary outcomes

Other Outcomes (1)

  • Complications of the Surgical Procedure (See Adverse Events Section for Results of This Outcome)

    2 years post-operatively

Eligibility Criteria

Age14 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • 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

You may not qualify if:

  • Intra-operative identification of International Cartilage Repair Society (ICRS) Grade 4 chondral lesion of \> 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
