Inclusion Criteria: * Patients between and including the age of 14-75 at the time of surgery * Patients who were diagnosed with lateral ankle instability by physician clinical assessment * Patients who underwent an ATFL repair with Arthrex InternalBrace augmentation device (does not require an isolated repair) Exclusion Criteria: * Significant secondary procedures done at the time of repair, including significant osteochondral lesions and/or significant microfracture of the talus or tibia that warrant modifying the typical lateral ligament repair post-op rehab protocol. (Minor microfractures and OCD lesions that do not warrant bone debridements, synovectomies, and bone spur removals are allowed) * Any concomitant orthopedic procedure that will extend the post-op rehabilitation (e.g., casting/immobilization) beyond the routinely prescribed rehab protocol following an ATFL reconstructive procedure. * Patients undergoing a Calcaneal osteotomy * Patients with less than 6 weeks follow-up * Patients with incomplete medical records * Patients with Worker's Compensation Cases * Any patient with a history of infection of the ankle predating the ankle repair * Any orthopedic issue outside of the ankle that the Investigator feels may impede functional endpoint outcome measures. * Patients who have a medical history that would likely make the patient an unreliable research participant
