Risk Factors for Contralateral ACL Injury: A Single Institution Case –Control Study

J Knee Surg DOI: 10.1055/s-0037-1615823Our purpose was to evaluate if there is any association between requiring contralateral anterior cruciate ligament (ACL) reconstruction and various: (1) demographics, (2) patient characteristics, and (3) surgery-specific factors. A prospectively collected database at a single institution was queried to find all patients who underwent primary ACL reconstruction between 2012 and 2014. We identified 312 primary ACL reconstruction patients with a mean age of 24 years and a mean follow-up of 3 years (range, 2–5 years). This cohort was compared with all those who had primary ACL reconstructions during the same time period without a contralateral procedure. We evaluated: (1) incidence, (2) demographic variables, (3) family history, (4) graft choice, (5) activity causing injury, and (6) mechanism of injury (contact versus noncontact). There were 16 patients (4.8%) with a mean age of 21 years and a mean follow-up of 3 years that required a contralateral reconstruction. More females required contralateral reconstruction when compared with the control cohort (p = 0.049). However, there was no difference in the mean age between the cohorts (p = 0.32). Those who underwent reconstruction using a tibialis anterior allograft were far more likely to require a contralateral reconstruction (p = 0.0002). Bone-tendon-bone patellar autograft (p = 0.16), hamstring autograft (p = 0.76), and hamstring allograft (p = 0.68) had similar in...
