Brief Summary
The purpose of this study is to determine the effects of modifiable risk factors on patient-reported quality of life, physical activity levels, and risk of early osteoarthritis following revision anterior cruciate ligament (ACL) reconstruction. The investigators hypothesize that modifiable variables exist at the time of revision ACL reconstruction (e.g., cause of failure, current graft source and type, surgical exposure, and femoral and tibial tunnel position) which will be predictors of patient-reported outcomes.

Outcome Measures
Primary Outcomes (1)
Graft re-rupture
2, 6, 10, and 20 years after revision ACL surgery
Secondary Outcomes (1)
Patient based outcome measures
2, 6,10, and 20 years after revision ACL surgery
Eligibility Criteria
All ACL-deficient candidates scheduled for a revision ACL reconstruction at one of the participating MARS sites.
You may qualify if:
- All ACL-deficient candidates presenting to the clinic, between the ages of 12†and 65, scheduled to have a revision ACL reconstruction by a participating (MARS Study) surgeon.
- All participants must have undergone a primary ACL reconstruction in the past and are currently identified as having experienced failure of their primary ACL reconstruction, as defined by either MRI, knee laxity (KT \> 5mm), a positive pivot shift or Lachman's, functional instability, and/or by arthroscopic confirmation.
- All ACL-deficient patients seeking a revision ACL reconstruction that have either partial (Grade I or II) and/or complete (Grade III) simultaneous ligamentous injuries to the collateral ligaments (MCL or LCL) and/or the posterior cruciate ligament (PCL) will also be included.
- Non-operative treatment of patients with ACLR failure are also eligible to participate.
- any autograft
- Fresh-frozen allografts from a single donor source (Musculoskeletal Transplant Foundation (MTF); Edison, NJ). These grafts should consist of either:
- bone-patellar tendon-bone
- tibialis anterior/posterior
- achilles tendon
You may not qualify if:
- Patients presenting with prior infection, arthrofibrosis, or regional pain syndrome.
- Subjects will be excluded if their allograft source does not come from MTF.
- Patients unwilling or unable to complete their repeat questionnaire two years after their initial visit.
