Sacroiliac Joint Prolotherapy
Prolotherapy, also known as “proliferation therapy”, is the injection of an osmotic or chemical irritant into a tendon or ligament in order to produce an inflammatory response within the injured tissue. The inflammatory response stimulates production of connective tissue and release of growth factors within the injected site for the desired effect of strengthening the target tissue, and thereby relieving musculoskeletal pain.
The majority of randomized controlled trials on the use of prolotherapy have been for nonspecific chronic low back pain; prolotherapy for the sacroiliac joint has not been well researched. One study on 19 patients who had previously experienced significant but temporary pain relief after intra-articular sacroiliac joint injections found positive responses in 79%, 63%, and 58% at 3, 6, and 12 months, respectively.9
A 2010 randomized controlled trial of intra-articular prolotherapy vs. sacroiliac joint steroid injection found a cumulative incidence of ≥50% pain relief at 15 months in 58.7% of the prolotherapy group vs. 10.2% of the steroid injection group.10
In a prospective cohort study on 25 patients, 76% of the patients seen for follow up at 12 months had a positive clinical outcome, which decreased to 32% at 24 months.11
