Growth Factor Concentrate (GFC) injection is an advanced regenerative treatment used for early to moderate knee osteoarthritis. It is prepared from the patient’s own blood and contains concentrated growth factors that help reduce inflammation, relieve pain, and support cartilage healing. Unlike conventional PRP, GFC is an acellular preparation rich in purified growth factors with minimal cellular components The procedure involves drawing blood, processing it to isolate growth factors, and injecting the concentrate into the knee joint under sterile conditions. GFC therapy is minimally invasive and usually performed as an outpatient procedure. Clinical studies have shown that serial intra-articular GFC injections can improve pain, stiffness, and functional outcomes in patients with early knee osteoarthritis
