Neutrophil-Reduced Platelet Rich Plasma with Optimal Platelets Concentrations for Epicondylitis of the Elbow

SUMMARY Background. Autologous platelet-rich plasma (PRP) therapy has been applied in treat­ment of medial or lateral elbow epicondylitis; however, its efficacy is variable possibly due to differences in PRP platelet or neutrophil concentrations. We prepared neutro­phil-reduced PRP with optimized platelet concentrations, and investigated therapeu­tic effects of the platelet-optimized PRP for elbow epicondylitis. Methods. We treated … Continued
