A method of surgical treatment of Freiberg-Koehler disease using shortening osteotomy, microfracturing of a bone-cartilaginous defect and its replacement with a chondro-scaffold collagen membrane

Freiberg-Köhler disease most commonly affects the head of the second metatarsal. The etiology of the disease is currently not fully understood, and there are no uniform approaches to treatment tactics. This article presents a clinical case of successful surgical treatment of Freiberg-Köhler disease using shortening osteotomy of the metatarsal bone, microfracture of the head and replacement of the cartilaginous defect using a collagen membrane allograft.
