Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Platelet-derived growth factor (PDGF) is supported by scientific evidence for use in the treatment of cartilage damage, though the evidence is moderate and largely preclinical or early clinical. PDGF is a key growth factor involved in tissue repair and regeneration, including the proliferation and migration of chondrocytes (cartilage cells) and the synthesis of extracellular matrix components necessary for cartilage health. In vitro and animal studies have demonstrated that PDGF can stimulate chondrocyte proliferation and matrix production, potentially enhancing cartilage repair. Additionally, PDGF is a component of platelet-rich plasma (PRP), which is increasingly used in orthopedic and sports medicine to treat cartilage injuries. Clinical studies of PRP, which contains PDGF among many other growth factors, show mixed but generally positive results in symptom improvement and cartilage repair, although the specific contribution of PDGF is difficult to isolate due to the complex mixture of factors in PRP. Isolated PDGF has been evaluated in some small-scale clinical trials for cartilage repair, with some studies reporting improved cartilage healing and function, but larger and more rigorous clinical trials are needed to confirm these effects. Overall, PDGF use for cartilage damage is scientifically plausible and partially supported by current evidence, but more high-quality human studies are needed to establish definitive efficacy.
