Osteochondral lesions (OCL) of the talus can be caused by isolated or recurrent traumatic events. The established surgical treatment techniques are predominantly based on defect coverage by stimulation of fibrous cartilage or transplantation of osteochondral tissue or chondrocytes. An alternative is the preservation of an intact autochthonous hyaline cartilage surface with reconstruction of the subchondral lamella and the natural joint congruence. This anatomical technique can be used for selected acute and chronic OCL and can frequently be carried out arthroscopically. This article presents the indications, contraindications, advantages and targets as well as the planning and execution of arthroscopically assisted transmalleolar internal fixation of a lateral OCL of the talus.
