Combined PRP and CCP Therapy Suppresses Inflammation and Protects Cartilage in Post-Traumatic Osteoarthritis

Year: 2026

Type: article

Abstract: This study aimed to evaluate the therapeutic effects of platelet-rich plasma (PRP) and Cervus and Cucumis polypeptide (CCP) injections in rats with post-traumatic osteoarthritis (OA). The model was established by transection of the anterior cruciate ligament, and the animals were subsequently treated with PRP and CCP. Articular cartilage degeneration was assessed through gross morphological observation, histopathological staining, and a standardized scoring system. Concurrently, pain-related behaviors, joint swelling, levels of inflammatory cytokines, and markers associated with extracellular matrix degradation were measured. The results demonstrated that, compared with the OA model group, PRP and CCP exhibited varying degrees of functional improvement, specifically, a reduction in pain-related behaviors and an alleviation of joint swelling. Furthermore, cartilage morphological damage was diminished, inflammatory marker levels decreased, and indicators of extracellular matrix degradation were attenuated. Histopathological examination of liver and kidney tissues revealed no apparent abnormalities. This study provides valuable experimental evidence for further treatment strategies for OA.
