The nonoperative treatment of osteochondritis dissecans of the knee.

Purpose Of Review: The purpose of this review is to update the reader on the controversial subject of osteochondritis dissecans (OCD) with a focus on nonoperative treatment indications, methods, and success rate.

Recent Findings: Work by an international multicenter study group ROCK (Research in OsteoChondritis of the Knee) will be reviewed including new classifications systems of healing, arthroscopy, radiographs, and MRI, along with new evidence on off-loading bracing compared to restricted weight bearing.

Summary: The paucity of evidence behind OCD treatment of the knee can lead to confusion for doctors, patients, and parents. The present review will bring more clarity to the subject.
