Fluoroscopically-guided therapeutic injection of the proximal tibiofibular joint in a patient with lateral knee pain

Proximal tibiofibular joint (PTFJ) pathology is an uncommon but perhaps underappreciated cause of lateral knee pain. While imaging guided therapeutic injections for diagnosis and management of joint related symptoms are now commonplace and numerous techniques for accessing most joints in the body have been documented, a technique for fluoroscopically guided injection of the PTFJ has not been yet described in the literature. We present a case of an adult patient who presented with lateral knee pain refractory to conservative management who opted for a fluoroscopically-guided therapeutic injection of her PTFJ.
