Platelet-Rich Plasma Reduces Retear Rates After Arthroscopic Repair of Small- and Medium-Sized Rotator Cuff Tears but Is Not Cost-Effective

In large tears, even with double-row repair, the beneficial effects of PRP alone are insufficient to compensate the progressed tissue damage. The study data suggest that PRP may promote healing of small- and medium-sized tears to reduce retear rates. However, despite the substantial biological effect, at current cost, the use of PRP is not cost-effective in arthroscopic repair of small- and medium-sized tears.
