A 23-year-old collegiate soccer player sustained a right knee injury 6 months ago. He has been treated with rest and rehabilitation but is unable to play at his previous level due to his knee "giving way." Physical exam reveals 10° varus alignment when standing and a varus thrust with walking. Strength is full compared to the other side. Ligamentous exam reveals a stable ACL and MCL, but opens to a varus stress and a 3+ posterior drawer and positive dial test at both 30° and 90° degrees of flexion. What is the best treatment option to allow this patient to return to competitive athletic activity?
