Arthroscopy for osteochondral lesions (LODA)

Arthroscopy is a surgical technique that involves using an optic to see inside the joint and miniature surgical instruments. The incisions are small and this form of surgery is less invasive than the technique known as "open". With the evolution of arthroscopic techniques and instruments, arthroscopy allows today to treat a significant number of osteo-articular pathologies.

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.

  • Anesthesia : general + loco regional
  • Technique : arthroscopy
  • Immobilization : 45 days without support the first 3 weeks
  • Rehabilitation : from the first postoperative consultation
