Osteochondritis Dissecans: Current Understanding of Epidemiology, Etiology, Management, and Outcomes.

J Bone Joint Surg Am 2021 Jun;103(12):1132-1151

Department of Orthopedic Surgery, University of Minnesota, Minneapolis, Minnesota.

: Osteochondritis dissecans occurs most frequently in the active pediatric and young adult populations, commonly affecting the knee, elbow, or ankle, and may lead to premature osteoarthritis.

: While generally considered an idiopathic phenomenon, various etiopathogenetic theories are being investigated, including local ischemia, aberrant endochondral ossification of the secondary subarticular physis, repetitive microtrauma, and genetic predisposition.

: Diagnosis is based on the history, physical examination, radiography, and advanced imaging, with elbow ultrasonography and novel magnetic resonance imaging protocols potentially enabling early detection and in-depth staging. Read More
