Honored to share my perspective on Lindsey Vonn's remarkable comeback attempt. As an orthopedic surgeon working with U.S. Ski and Snowboard, I can say that while skiing with an ACL tear isn't typical, elite Alpine skiers like Lindsey have unique biomechanics and compensatory strength that make this possible. Her determination and physical conditioning put her in that very rare category of athletes who might just pull this off. 🎿
