Video Summary

The video presented by Julia Retske discusses the impact of lateral extra-articular tenodesis (LET) on the signal intensity of ACL grafts on MRI. Dr. Green and Dr. Kordasko have been using LET in ACL reconstruction for high-risk adolescents since 2015, resulting in positive outcomes and a high return to sport. Previous studies have shown that ACL graft signal hyperintensity at two years postoperative can increase the risk of graft rupture. This study aimed to evaluate ACL graft maturity using signal intensity ratios on MRI at 6 months, 1 year, and 2 years postoperative. The findings suggest that the addition of LET to ACL reconstruction with quadriceps tendon autograft improves graft signal on MRI at 2 years postoperative, potentially due to a protective effect.
