Purpose
Chondroblastomas are benign cartilaginous tumors located in epiphysis or apophysis of a long tubular bone. Standard treatment is surgical curettage and packing of the area. Local recurrence rates of 8%-20% have been reported. Percutaneous radiofrequency ablation could have a role in this tumors.

Material and methods
Two patients with clinically and radiologically suspected chondroblastoma were treated by mean of this approach. One lesion were located in the femoral epiphysis and the other was located in the tibial epiphysis. Both of them were 13 years-old boys. After informed consent were obtained, procedures were performed under general anaesthesia using CT guidance. Access to the lesions were gained by using a 14G-bone biopsy needle. Biopsy confirmed the suspected diagnosis. Ablation were performed with a 10-mm exposed cool-tip. Three separate treatments were performed during a single session to encompass the entire lesions.

Results
Patients were discharged the day after the procedure. Both of them experienced pain relief immediately. They remains free of symptoms after 18 and 30 months without complications.

Patients were discharged the day after the procedure. Both of them experienced pain relief immediately. They remains free of symptoms after 18 and 48 months without complications
Conclusion
Percutaneous radiofrequency ablation could be a safe and effective first-line treatment for chondroblastoma
