Ultrasound-guided percutaneous needle tenotomy (PNT) alone versus PNT plus platelet-rich plasma injection for the treatment of chronic tendinosis: A randomized controlled trial.

研究概要

Forty patients with chronic tendinosis were randomized to receive a percutaneous needle tenotomy with a leukocyte-rich platelet-rich plasma (LR-PRP) injection (n=21) or percutaneous needle tenotomy alone (n=19). Outcomes of interest included current pain, average pain, function, general well-being, and sleep quality, measured using 10-point scales. Outcomes were assessed up to 104 weeks post-treatment. With the exception of current and average pain scores at 6 weeks which were significantly lower in the tenotomy only group, all outcomes were similar between groups, at all time-points. No serious adverse events were reported.
