Autologous Conditioned Serum: Functional and Clinical Results

"Fifteen patients with clinical and radiological signs of OA of the knee were recruited for this study. 50mL of whole blood were taken using a special syringe containing CrSO4-coated grade glass beads in order to promote IL-1ra synthesis and aggregation.The incubation period lasted 7 hours after which, the blood-filled syringes were centrifuged and the serum supernatant was filtered and aliquoted into four 3mL portions. The aliquots were stored at -20oC until their use was necessary.~Patients received 1 intra-articular injection for 4 consecutive weeks at the site of OA."
