Arthroscopic management of osteochondritis dissecans of the first metatarsal head.

Osteochondritis dissecans of the first metatarsal head can be painfully disabling in the adolescent. It may be the forerunner of adolescent and adult hallux rigidus. Arthroscopic surgical treatment of this osteochondritis dissecans lesion is technically feasible. The case reported here suggests that arthroscopic treatment, at an early stage, can render a patient symptom-free and allow a return to full activity.
