High Ankle Sprains vs. Chronic Instability: When to Fix the Syndesmosis (with Dr. Michael Sileo) | The Sports Medicine Research Rundown Ep. 22

How do you differentiate a standard inversion ankle injury from an occult high ankle sprain on the sideline? In Episode 22 of The Sports Medicine Research Rundown, host Tim Tyler, MS, PT, ATC, sits down with orthopedic sports medicine specialist Dr. Michael Sileo to dissect acute ankle evaluation, imaging protocols, and post-operative management.

Together, they review a landmark study from the American Journal of Sports Medicine evaluating midterm outcomes after suture-button (TightRope) fixation for arthroscopically confirmed syndesmotic instability alongside chronic lateral ligament reconstruction. They also dive into sideline trauma triage, the Ottawa Ankle Rules, the physiology of early cryotherapy, and progressive proprioceptive rehabilitation.
