The aim of this study was to evaluate if PRP injection decreases pain and disability due to trapeziometacarpal OA compared with placebo.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Double-blind trial of 90 patients with painful trapeziometacarpal OA that were randomized to a single intra-articular injection of either PRP (n = 45) or placebo (saline injection) (n = 45) in the trapeziometacarpal joint. The primary outcome was change in pain on load (Numerical Rating Scale (NRS) 0 to 100) from baseline to 6 months after injection. Secondary outcomes were change in pain on load after 3 months; change in pain at rest; Patient-Rated Wrist and Hand Evaluation; Disability of the Arm, Hand, and Shoulder score; range of motion; key pinch; and 3-finger pinch strength, after 3 and 6 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>One PRP patient was lost to follow-up.

At 6 months, median pain change was \u221210 (95% CI \u221220 to 0) in the PRP group and 0 (95% CI 0-10) in the placebo group (absolute difference \u221210 (\u221220 to 0), p = 0.22).
