Platelet-Rich Products Can Have Variable Effects on Outcomes After Arthroscopic Full-Thickness Rotator Cuff Repair: A Meta-analysis of Randomized Controlled Trials

The authors aimed to evaluate the effects of various platelet-rich products on clinical outcomes in patients undergoing arthroscopic full-thickness rotator cuff repair. Their meta-analysis of 15 randomized controlled trials found that these products significantly reduced retear rates and improved certain functional scores, although the clinical significance of these improvements may be limited. They recommend using platelet-rich products with low leukocyte counts and high platelet concentrations, particularly in liquid form and administered via a single intratendinous injection during surgery.
