Abstract
Large osteochondral defects of the talus present a difficult clinical problem to orthopaedic surgeons. Massive-volume deep cystic lesions are rare. The use of an allograft transplantation offers an alternative in the treatment of these extensive lesions involving the talar dome.We report on the outcome after an osteochondral fresh frozen allograft transplantation in a case of a 53-year old-woman with a massive cystic lesion of the talus.No evidence of resorption or failure of the graft has been observed after 1 year of follow up. Radiological examination shows signs of union and incoroporation of the graft without subchondral collapse or fragmentation. After 1 year se has no pain and she is able to walk independently without assistance.The present case offers a surgical alternative for massive lesions of the talus, that use rigidly fixed ostechondal allograft transplantation. Mid and long term survival of these kind of allografts remains unknown. Despite the good results after one year, worse outcomes or failures can be expected in the future.
