Osteochondritis dissecans (OCD) of the knee is a condition that has continued to perplex the orthopaedic community in its origin, despite clear advances in identification and treatment. The incidence of this potentially disabling condition has remained relatively steady, but with a shifting distribution towards young, athletic males as the primarily affected demographic. The condition commonly presents insidiously as vague knee pain but may advance to overt mechanical symptoms due to loose body formation in the joint. OCD lesions are typically classified with magnetic resonance imaging (MRI) as either stable or unstable based on the mechanical integrity of the fragment and the state of the underlying subchondral bone. The purpose of this paper is to review the current understanding of pediatric OCD of the knee, contemporary treatment principles including methods to promote OCD lesion healing, fixation methods, and salvage techniques.
