Osteochondritis dissecans of the first metatarsophalangeal joint: arthroscopy and microfracture technique.

Osteochondritis dissecans (OCD) is a localized disorder of the joint surface by which a segment of subchondral bone and its overlying cartilage become fragmented. Arthroscopic treatment of OCD of the first metatarsophalangeal joint consisted mainly of debridement and loose body removal. The microfracture technique for the treatment of OCD of the first metatarsophalangeal joint is presented for the first time. The technique has been shown to be a safe and technically uncomplicated first-line treatment.
