Treatment of osteochondral lesions of the talus / 中华创伤骨科杂志

ABSTRACT

Osteochondral lesions of the talus are rare.The factors leading to them include trauma,chronic fatigue,family history,and idiopathic necrosis.The patients present with ankle pain,swelling,bruise,limited mobility and limp at an early stage while joint stiffness and walking and moving pain at a late stage.Normal check is likely to overlook them,resulting in delayed diagnosis and treatment.If an osteochondral lesion of the talus is suspected with negative X-ray manifestations,further radionuclide bone scan or MRI is indicated for definite diagnosis.As there is no blood supply to the talar cartilage which is relatively too small,it is difficult to treat osteochondral lesions of the talus.Early mild lesions can be treated by conservative therapy.If conservative treatment fails or the lesions deteriorate,surgery is required.This paper reviews the research progress in the treatment of osteochondral lesions of the talus.
