The Application of All-arthroscopic Technique to Deep Osteochondral Lesions in the Talus With Scaffold and Autograft Bone Taken From the Tibial Plafond.

Osteochondral lesions in the talus are frequently seen disorders that can cause chronic ankle pain. Surgical treatment is determined by the size and location of the lesion. The microfracture procedure and additional application of scaffold technique have gained popularity for the treatment of small osteochondral defects. However, these techniques may be insufficient and have poor outcomes in deep lesions. Therefore, several different invasive surgical techniques that require the malleolar osteotomy have been described. Problems associated with the invasive surgical intervention may be seen such as reduction loss in the osteotomy site, delayed union or nonunion, permanent pain, and/or swelling. We describe a new all-arthroscopic technique for the treatment of deep talus osteochondral lesions using an autologous bone graft taken from the tibial plafond region together with a chitosan-based noncellular scaffold.
