title: Osteochondritis dissecans with a large osteochondral free body in the posterolateral compartment of the knee: a case report.
abstract: A large osteochondral fragment trapped in the posterolateral compartment of a knee was removed from a posteromedial portal through the trans-septal portal and fixed on an osteochondral defect of the lateral femoral condyle in a 16 year-old boy. When a free body in the posterolateral compartment is so large that enlargement of the portal site is required for removal, doing so from a posteromedial portal is safer and easier than from a posterolateral portal.
