Platelet-rich plasma: Definition, Uses, and Clinical Overview
Platelet-rich plasma is a concentrated portion of a person’s own blood that contains a higher-than-usual number of platelets. Platelets release signaling proteins that can influence inflammation and tissue repair. In orthopedics and sports medicine, it is commonly used as an injection for tendon, ligament, muscle, and joint problems. It is also discussed in knee care for conditions like tendinopathy and some forms of osteoarthritis.
