摘要

We read with interest the letter from Anitua et al. in response to our randomized, blinded, controlled, clinical trial evaluating the use of plasma rich in growth factors (PRGF) in the repair of the rotator cuff, recently published in Arthroscopy (January 2013). We are grateful for their contribution to improve the discussion on the topic, because we acknowledge that for the design of our randomized controlled trial (RCT), we took into consideration their previous results on the application of PRGF in maxillofacial surgery and orthopaedics and, thereafter, we strictly followed their guidance to prepare the PRGF and their advice for its use in the surgery.
