Quantitative MRI of the Hamstring Muscles Ten Years After Autograft Hamstring ACLR

Video Transcription

Video Summary

In this video, Will Holden presents a study conducted by the Moon Knee MRI Group and the Program for Advanced Musculoskeletal Imaging at Cleveland Clinic, led by Dr. Carl Wernosky and Dr. Xiaojuan Li. The study, funded by two NIH R1 grants, focuses on the functional recovery of the semitendinosus and gracilis muscles following hamstring autograft ACL reconstruction. The study includes 120 patients who underwent ACL reconstruction and analyzes factors such as muscle cross-sectional area, fatty infiltration, and myotennis junction distance. The findings show that while the majority of hamstring tendons regenerate, there is a decrease in muscle size, increased fat infiltration, and a shift in the myotennis junction. The research concludes that approximately one-third of harvested hamstring tendons regain normal function, one-third have partial function, and one-third have minimal function. The video ends with acknowledgments to the Moon Group, NIH, Arthritis Foundation, PAMI, and the Biomedical Engineering Department at Cleveland Clinic.
