Medial approach to knee and supporting structures. A, Skin incision. B, Skin flaps have been retracted. C, Sartorius has been retracted posteriorly, exposing semitendinosus and gracilis. D, All three components of pes anserinus have been retracted posteriorly to expose tibial attachment of tibial collateral ligament. E, Medial parapatellar incision has been made through retinaculum and synovium. F, Three components of pes anserinus have been retracted posteriorly to expose posteromedial corner. G, Medial head of gastrocnemius has been separated from posterior capsule of knee and has been retracted. Capsulotomy is made posterior to tibial collateral ligament.
