Comparison Analysis of Autologous Conditioned Plasma.
Autologous Conditioned Plasma (ACP) has a wide range of potential uses in modern orthopaedics. The aim of this study was to examine the characteristics of proprietary ACP and compare them with those of ACP produced using a commercially available kit.



In the hospital laboratory, 20 samples of ACP taken from patients and prepared according to the commercially available kit protocol with a double syringe system were compared with 40 ACP preparations made using disposable sterile equipment available in the hospital.



The mean platelet concentration in the ACP samples prepared according to the Arthrex protocol was 2.02 (range 1.16 to 2.64) times greater than in peripheral blood, while the concentration in the proprietary preparation was 1.61 (range 0.82 to 2.52) times higher. However, the mean platelet density in the proprietary preparation (n = 24) was 1.98 (range 1.48 to 2.52) times that of peripheral blood within 20 minutes of collection, and 1.41 (range 0.84 - 1.87) times after 20 minutes (n = 16). Therefore, the proprietary method of producing ACP is comparable to that of the commercial kit with regard to platelet density (p>0.05).



Using disposable hospital equipment and with a relatively short time between ACP preparation and testing, it is possible to obtain a suitable proprietary platelet-rich preparation comparable to one produced using a commercial system.
