A new study compares platelet-rich plasma injection with dry needling as potential therapy in rotator cuff injury. Two ultrasound-guided treatments, either platelet-rich plasma injection or dry needling, were given with a 4-week interval in between. Positive results were seen in both the Platelet-rich plasma group and the dry needling group. But at 6-month follow-up, patients from the PRP group demonstrated considerably greater relief in pain and improvement in function than the dry needling group. This study provides evidence that platelet-rich plasma therapy could be a safe and useful treatment for injured tendons and partial tears of the rotator cuff.
Understanding the negative influence of cortisone, more biologic based options are needed to provide surgical alternatives to the standard of care.
