The study included 34 patients with a wide range of tendon and soft tissue injuries, from rotator cuff tendinitis to plantar fasciitis, an inflammation on the bottom of the foot. In the first stage of the two-part treatment, researchers used high-resolution ultrasound technology to guide a needle to the injured area, and the physicians repeatedly poked the tendon with the needle, inducing minor bleeding within the tissue.
“The needle breaks up nonhealing, degenerative tissue and induces bleeding, hopefully converting a chronic, degenerative injury into an acute injury that has healing potential,” Dr. Smith explains. Afterward, patients received an injection of concentrated platelets from their own blood. The platelets release growth factors into the area to start the healing process.
