Review Question - QID 217679

A 35-year-old male sustains a pivoting injury while playing soccer and presents to your office complaining of persistent swelling and feelings of instability. He denies prior knee pain. On examination, he has a 2B Lachman with a large joint effusion. There is no varus/valgus laxity noted. Radiographs demonstrate mild osteoarthritic changes medially and full-length lower extremity films demonstrate a mechanical axis that crosses medial to the center of the knee joint, measuring 11º of deformity. You calculate the tibial slope to be 7º. What procedure(s) would best improve his function in this scenario?
