platelet-rich plasma (platelet-rich plasma, PRP) refers to platelet concentrate extracted from autologous blood by centrifugation. After the platelet in PRP is activated, it can release a variety of biologically active substances such as growth factor , cytokine and antibacterial peptide , which can promote the proliferation of cells, differentiation, matrix synthesis, tissue regeneration and repair, etc.
platelet-rich plasma technology has a wide range of therapeutic effects in the field of orthopedics, including repair of ligament/tendon injury, meniscus articular cartilage injury and repair, bone defect repair, spinal fusion application, and prevention of bone and joint infection. It can be used in knee arthritis, rotator cuff injury, meniscus injury , ligament injury , acute chronic tendonitis, plantar fasciitis , tennis elbow, golf elbow, Achilles tendonitis , old fracture not healing, bone defect, chronic non-healing wounds and other diseases.
PRP can treat cartilage damage in knee joint , reduce inflammatory response, and promote chondrocyte proliferation and division. PRP is rich in platelets and contains fibrin and a small amount of leukocyte . Among them, after platelets are activated, they can release a variety of biologically active factors, promote chondrocyte proliferation, division, and promote cartilage regeneration; fibrin plays the role of a biological scaffold in the repair of cartilage, which is conducive to the generation of a variety of biologically active factors and promotes tissue repair; a small number of white blood cells are distributed on the surface of the synovial membrane, which can reduce the inflammatory response of the synovial membrane and play a certain anti-infective role. In addition, PRP is completely extracted from autologous blood and has no immune rejection. It is a highly safe treatment method.
