Quick summary: Comparison of PRP with cortisone for carpometacarpal arthritis with much better long-term results from PRP treating early to moderate arthritis.

Full summary: 33 patients with clinical and radiographic osteoarthritis of the TMJ (16 patients received received 2 ultrasound-guided IA-PRP injections, 17 patients received 2 ultrasound-guided intra-articular methylprednisolone and lidocaine injections at a 2-week interval)… after 12 month follow up, IA-PRP yielded significantly better results in comparison with corticosteroids in terms of VAS score (P = 0.015), Q-DASH score (P = 0.025), and patients’ satisfaction (P = 0.002). Corticosteroids offer short-term relief of symptoms, but IA-PRP might achieve a lasting effect of up to 12 months in the treatment of early to moderate symptomatic TMJ arthritis
