Platelet-Rich Plasma Therapy May Help Repair Damaged Knees
Our bodies have an incredible ability to heal after injury and illness. Platelets are blood cells that cause blood to clot and play an important role in tissue healing. Experimental platelet-rich plasma therapy harnesses the healing ability of these cells to repair damaged tissue, such as a torn Achilles tendon.
This type of treatment that induces the body to heal itself is called regenerative medicine. For people with osteoarthritis, the procedure involves taking a patient’s blood, extracting the platelets, and injecting them directly into the knee joint. When combined with other treatments, platelet-rich plasma reduces knee pain and stiffness from osteoarthritis. Although the results are promising, more studies are needed to determine if the therapy is an effective treatment for knee pain on its own.
