Ultrasound-guided thermal radiofrequency ablation to treat refractory knee and hip pain: Outcomes of a case series

A number of options are currently available to treat symptomatic knee and hip pain. Among them, there is the use of thermal radiofrequency ablation. It is a more recent technique and we still have a lack regarding safety and effectiveness. In this report, we briefly present a case series of patients with refractory knee and hip pain, treated with thermal radiofrequency ablation, where we discuss the results in safety and effectiveness, concerning not only the pain control, but also the return to participation in activities.
