AOSSM 2022 Annual Meeting Recordings - no CME-What Have We Learned from MARS?

Video Transcription

Video Summary

The video provides a summary of a multi-center anterior cruciate ligament (ACL) revision study called MARS (Multicenter ACL Revision Study). The study included 1,234 patients who underwent revision ACL surgery between 2006 and 2011, with a two-year follow-up rate of 92%. The purpose of the study was to determine predictors of clinical outcomes using multivariate analysis. The study found that graft re-rupture rates were 3.3% at two years and 5.8% at six years, with allografts being more likely to experience re-rupture compared to autografts. Femoral malpositioning was the most common technical cause of failure, and factors such as age, BMI, and baseline PROs influenced outcomes. Reoperation rates were 16% at six years, with the most common reoperations being related to the meniscus and revision ACL. Multiple revision ACL surgeries had lower activity levels and increased chondral injuries. Overall, the study provides valuable insights into ACL revision surgery outcomes.
