Osteochondritis dissecans (OCD) of the knee
is a focal idiopathic alteration of subchondral bone and/or its
precursor with risk for instability and disruption of adjacent
cartilage. Treatment options focused on preventing premature
osteoarthritis vary depending on multiple patient and lesion
characteristics, including lesion mobility.
In conclusion, age, effusion, and loss of
motion can predict knee OCD lesion mobility at the time of
arthroscopy. Education about lesion mobility can help with surgical
planning and patient and family counseling.
