title: Locked knee and osteochondritis dissecans.
abstract: Two patients presenting with a locked knee are described. In both cases a loose body from an osteochondritis dissecans defect had wedged beneath the anterior horn of the lateral meniscus, creating a block to extension which could not be reduced. Arthroscopy and arthroscopic methods proved unsuccessful in the removal of the loose body.
