All patients with sacroiliac joint pain diagnosed by a back pain specialist will undergo physical examination maneuvers and a test lidocaine injection of the joint. Patients who meet eligibility requirements will be randomized in a single-blind randomized controlled manner with a 50% chance of receiving platelet-rich plasma versus steroid/anesthetic injection of the sacroiliac joint(s).
The purpose of this study is to determine if platelet-rich plasma is superior to steroid/anesthetic for the treatment of sacroiliac joint pain.
