A case of arthroscopic treatment of chondroblastoma-induced chondropathy situated at the posterior talus: curettage, bone grafting, and augmentation with cell-free matrix

Abstract

Chondroblastoma located in the talus is a rare incidence, and due to the weightbearing duty of the talus, the results of local excision may not be favorable. While the volume of the tumor increases, more sophisticated techniques may be undertaken. Cell-free matrix application for extensive osteochondral defects is gaining popularity for its structural support when it is used with microfracture and autograft application. In this case report, we present a patient with 13 × 20 × 8mm-sized chondroblastoma located in the talus. After evaluation of the mass, we performed curettage, iliac crest autograft application, and augmentation with cell-free matrix. After uneventful clinical follow up, we present our patient's postoperative second year magnetic resonance imaging and functional status.
