Ankle arthroscopy for osteochondral lesions of the dome under the talus or under the talus (LODA) consists of a small incision at the anteromedial level to introduce the optic and an antero-lateral incision to introduce the instruments.
In the first stage of surgery, the surgeon will observe lesions of the tissues, cartilage and bones.
Then, a debridement will performed (i.e : a cleaning of the joint) to remove any micro-fragments. For this it uses curettes or an instrument called "shaver", ie a kind of motorized milling cutter.
Other gestures : curettage, avulsion, bone graft, mosaicplasty, or microfracturing, are performed either alone or in combination to obtain bleeding from the cancellous bone which healing will promote fibocartilaginous repair.
