Joint fluid samples were harvested in both groups at the time of ACLR (visit 3). The joint fluid and PRP samples were subject to inflammatory and chondrodegenerative biomarker analysis for the following: interleukin (IL)-1ß, IL-10, IL-6, granulocyte-macrophage colony-stimulating factor, IL-5, interferon (IFN)-γ, tumor necrosis factor-α, IL-2, IL-4, and IL-8.</p><p><strong>Results: </strong>The final analysis was completed on 8 participants in the control group and 8 in the intervention group.
