40 patients affected by severe hip osteoarthritis were included in the study which was designed to assess the safety and symptomatic changes of PRP injections for hip arthritis. Each patient received three intra-articular injections of PRP, which were administered once a week.
Statistically significant reductions in pain scores were reported at 7 weeks and 6 months. 23 (57.5%) patients reported a clinically relevant reduction of pain (average of 45%, range 30–71%). More importantly, pain relief was shown to be sustained at 6 months with a parallel reduction of disability. Side effects were negligible and were limited to a sensation of heaviness in the injection site.
We look forward to more studies being published detailing the safety and efficacy of Platelet-Rich Plasma Injections for a wide array for joint, tendon, and ligament problems which have failed to respond to other treatments- setting the stage for a new era in regenerative medicine.
