Osteochondral lesion of the talus: prognostic factors affecting the clinical outcome after arthroscopic marrow stimulation technique.

The treatment of symptomatic osteochondral lesions of the talus (OLT) has difficulties and limitations caused by the poor regeneration of articular cartilage and the limited access to the ankle joint. It is important that the surgeon understand the causes of failure as well as the factors influencing the results of arthroscopic treatment of OLTs. The presence of such a risk factor may encourage surgeons to find new treatment strategies as well as counsel patients differently.
