How does platelet rich plasma therapy for shoulder injuries work?

Unknown. There is a debate in the literature as to whether prp is helpful. It is mainly used in rotator cuff repairs. Prp has many stimulating growth factors that is thought to expedite rotator cuff healing.
Data not strong... The theory is that the body can't on its own get enough healing or growth factors to the area (tendon), but concentrated platelet injected there enhance the nutrients and growth factors to allow the body to heal it. While many doctors do this, the most robust scientific trials (randomized controlled trials) have been ambiguous as to if it really works. Insurance probably won't cover it (check...).
