- In the article outlined below, Dr. Randelli and his colleagues have confirmed that valuable growth factors are released when performing an arthroscopic acromioplasty. This is a landmark paper that will be cited many times as we try to understand how to use platelet rich plasma and other biologic treatments. His work for the first time has confirmed that the mechanical removal of an acromial spur has biologic consequences. Excellent information.

Release of growth factors after arthroscopic acromioplasty.
It has recently been postulated that a variety of growth factors may be released from cancellous bone after an acromioplasty. The aim of this study was to demonstrate the presence of growth factors in the subacromial space after acromioplasty. Between October 2006 and March 2007, 23 patients underwent arthroscopic acromioplasty. A sample of at least 3 ml of fluid from the shoulder was obtained 15 min after the end of the procedure. At the same time another sample of 3 ml of the patient's venous blood was obtained as a control. The concentrations of growth factors in the fluids collected were determined using enzyme-linked immunosorbent assay (ELISA). The growth factors assayed were platelet-derived growth factor-AB (PDGF-AB), basic fibroblast growth factor basic (bFGF) and transforming growth factor beta 1 (TGF-beta1). The concentrations of TGF-beta1 (p = 0.0001), PDGF-AB (p = 0.02), and bFGF (p <>
