Efficacy of Platelet Rich Plasma vs. Corticosteroid Injections for Treating Greater Trochanteric Pain Syndrome

The object of this study is to compare the effect of PRP versus Corticosteroid injection on pain in patients with Greater Trochanteric Pain Syndrome up to 12 months after treatment. It is believed that PRP will be as good as corticosteroids for short term pain relief, and will produce longer lasting pain reduction.

The purpose of this study is to compare the efficacy of Platelet Rich Plasma (PRP) injections versus Corticosteroid injections in treating patients that have failed noninvasive management for Greater Trochanteric Pain Syndrome (GTPS). We will be comparing in both the short term (0-6 months) and in the long term (6-12 months). It will be a Double-Blinded Randomized Clinical Trial. Patients with GTPS will be randomly assigned to either the Corticosteroid group or PRP group. There will be a total of 50 participants enrolled with 25 in each group. The PRP group will receive 3 mL of autologous plasma injection into the area of tendinopathy utilizing ultrasound guidance. One (1) injection per month will be administered for a total of three (3) injections. The Corticosteroid Group will receive 2.0 mL's injection of lidocaine and 40mg of Triamcinolone into the area of tendinopathy utilizing ultrasound guidance on their first injection. They will then receive 2.0 mL's of 1% lidocaine and 3.0 mL's of 0.9% Sodium Chloride per month for a total of three (3) injections. Both groups will be referred to physical therapy. Participant's pain will be assessed using a Visual Analog Scale (VAS) and the Nonarthritic Hip Score (NHS) for function at the beginning of the treatment and then again at 1, 3, 6, 9, and 12 months after the initial injection.
