Arthroscopic Debridement and Grafting of an Intraosseous Talar Ganglion

We report the case of a 41-year-old man with right ankle pain and swelling who had an intraosseous talar ganglion in the medial part of talar dome. A surgical procedure was performed using the 3-portal arthroscopic approach. The softened chondral surface was removed and the content of the cyst was discharged arthroscopically. The sclerotic rim was abraded until the bleeding spongious layer was seen. A grafting procedure was also performed arthroscopically. A trocar was introduced into the defect from the superomedial portal. Autografts were impacted using a cylindrical rod through the trocar into the defect. The clinical and radiologic results at the 1-year follow-up were satisfactory. We encountered no complications postoperatively. We conclude that arthroscopic debridement and grafting of an intraosseous ganglion adjacent to the articular surface may be a better option compared with open surgery.
