Plasma rich in growth factors in arthroscopic rotator cuff repair: a randomized, double-blind, controlled clinical trial.

Purpose: The aim of this study was to determine whether addition of plasma rich in growth factors (PRGF) improves functional and structural outcomes after arthroscopic repair of full-thickness rotator cuff tears.

Methods: The study design was independent (investigator-sponsored), randomized in parallel groups, double-blind, and controlled with a conventional surgical technique clinical trial. Sixty-nine patients with rotator cuff tears were included.
