Injecting injured Achilles tendons with platelet-rich plasma (PRP) is no more effective than dummy injections when it comes to alleviating pain and improving activity levels, according to a new study in the Jan. 13 issue of the Journal of the American Medical Association.
Don’t jump to any conclusions based on one study, says Brian Halpern, M.D., an associate attending physician at Hospital for Special Surgery in New York City, who routinely uses PRP to treat tendon problems.
Although he is happy to see this treatment being studied in such a rigorous manner, the new study did not use imaging to see if the PRP injections changed the structure and helped to regenerate the damaged tendon.
Perhaps, just needling the tendon - which was done with both PRP and saline injection - stimulates the body’s own platelets to congregate in the injured area and speed the healing process. “The saline may look good because of the needling,” he says.
Still, “the improvement is not as great as I would have expected,” he says. “For me, the jury is still out and we need to do more studies and take it from there.”
