Video Summary

In this video summary, Harrison Schofield, a fifth-year orthopedic surgery resident at John Peter Smith Hospital in Fort Worth, Texas, presents research on alternate knee loading following ACL repair versus reconstruction. The study found that patient expectations for returning to the same level of sport following ACL reconstruction are high, but the actual outcomes are lower, with only 81% returning to any sport and 65% returning to their pre-injury level of sport. Additionally, there is a risk of graft re-rupture, contralateral ACL tear, and knee osteoarthritis following reconstruction. The study focuses on ACL repair, which has been abandoned in clinical practice but has recently gained renewed interest. The research compares knee joint loading and quadricep strength between ACL repair and reconstruction patients at the three-month postoperative mark. The ACL repair group showed significantly greater peak knee extension moment, net knee joint power, and quadricep strength, suggesting improved loading strategies and limb symmetry. These findings are unique and contribute to the existing literature on ACL repair and reconstruction. However, the study has limitations, including its short-term follow-up, small sample size, and potential for selection bias.
