**3.2 Osteoperiosteal graft**

Another option we have for the treatment of osteochondral lesions is the mosaicplasty technique with bone-periosteum graft of the iliac crest. Its two advantages compared to the conventional technique include the absence of joint morbidity from the donor site defect [54] and that the periosteum (with its pluripotent stem cells) has the potential to differentiate into fibrocartilage [56–63].
