Anterior intraosseous arthroscopic treatment of talar chondroblastoma: A case report

Chondroblastoma is a rare benign bone tumor that accounts for 1–2% of all primary bone tumors. Typically, chondroblastoma occurs in the epiphysis of a long bone, and approximately 4 % of all chondroblastomas occur in the talus. The treatment of talar body chondroblastoma is challenging the talus is surrounded by the tibia, fibula, and other tarsal bones. Here we report the case of a 15-year-old boy who developed chondroblastoma of the talar body. We performed tumor curetting, cancellous bone grafting, and β-tricalcium phosphate transplantation for using anterior intraosseous arthroscopy. The patient with no obvious recurrence 18 months after the surgery. Arthroscopic treatment for tumors of the talar body is safe, provides good visibility, and is less invasive.
