Inflammation and OA
Osteoarthritis (OA) was previously considered non-inflammatory. It is now well recognized that inflammatory mediators are produced and can be measured in joint fluids of patients with OA. This inflammation is a major risk factor in cartilage loss, pain, swelling, and stiffness. When management and treatment of OA consists of anti-inflammatory components, patients can improve their function and decrease pain levels. Platelet-rich plasma (PRP) is a cell therapy, that uses one’s own blood through joint injections, to reduce inflammation. Platelets are a high source of concentrated growth factors and inflammatory mediators. Platelets in PRP release many types of anti-inflammatory proteins that signal cells that lead to suppression of inflammation in OA.
