AMSTERDAM — A multicenter, double-blind, randomized, placebo-controlled trial examining the use of platelet-rich plasma injections in athletes for the treatment of acute hamstring injuries has shown the injections were no more effective than placebo.

Gustaaf Reurink, MD, and colleagues used a two-injection protocol where the first injection of platelet-rich plasma (PRP) or placebo was given 5 days post-injury and a second injection was given 5 to 7 days later.

A summary of Reurink’s presentation of the results at the European Society of Sports Traumatology, Knee Surgery and Arthroscopy Congress appears in the July/August issue of Orthopaedics Today Europe.

“If you look at our results, we found no benefit of the PRP on the time to return to play for our athletes,” Reurink said.

The median time to return to play for both groups was 42 days. Furthermore, re-injury rates were also similar for athletes in both the PRP and placebo groups in this study, according to Reurink.
