Injuries to the talar osteochondral bone can be treated in several ways: first, conservative treatment, including rest, plaster immobilization, and partial weight-bearing of the affected limb for 6-8 weeks, usually for adolescents with unclosed epiphyses and for patients with stage I and II X-rays; second, surgical treatment, for patients with stage I and II X-rays and stage I MRI, if conservative treatment is not effective. Patients with X-ray stage III or IV and MRI stage II should be treated with surgery as soon as possible. At present, arthroscopic surgery is mainly used, including arthroscopic clean-up of the lesion alone and arthroscopic clean-up of the lesion with microfracture. The advantage is that the surgery is less invasive, the postoperative recovery is fast, and the treatment of small area of osteochondral damage of the talus is effective.
