Platelet-rich plasma (PRP) injections have emerged as a promising non-surgical treatment option for knee osteoarthritis. This innovative approach harnesses the body’s natural healing capabilities to alleviate pain and potentially slow down the progression of the disease. PRP therapy involves extracting a small sample of the patient’s blood, processing it to concentrate the platelets, and then injecting the platelet-rich plasma directly into the affected knee joint. These concentrated platelets contain growth factors that stimulate tissue repair and reduce inflammation.
How Does PRP Reduce Knee Pain?
The core principle behind PRP therapy is the utilization of the body’s own growth factors to promote healing. Platelets, a component of blood, are rich in proteins that play a vital role in tissue regeneration. When injected into the knee, these growth factors can help repair damaged cartilage, reduce inflammation in the joint lining (synovium), and improve overall knee function. This process aims to provide pain relief and enhance mobility for individuals suffering from knee osteoarthritis.
What is Involved in a PRP Procedure for the Knee?
The procedure itself is relatively straightforward. A small amount of blood is drawn from the patient, similar to a routine blood test. This blood is then placed in a centrifuge, a device that spins the blood at high speeds to separate the platelets from other blood components. The concentrated PRP is then carefully injected into the knee joint, often with the assistance of ultrasound guidance to ensure precise placement. Because PRP uses the patient’s own blood, the risk of allergic reactions or adverse side effects is minimal.
Considerations for Knee PRP
While PRP therapy shows great potential, the effectiveness of PRP can vary depending on factors such as the severity of the osteoarthritis, the patient’s overall health, and the specific PRP preparation and injection technique used.

Many individuals experience significant pain relief and improved knee function following PRP treatment; however, is also important to note that this therapy is not always covered by medical insurance.
The Takeaway?
PRP therapy offers a minimally invasive and potentially effective option for individuals with knee osteoarthritis. By leveraging the body’s natural healing abilities, PRP aims to reduce pain, improve function, and potentially slow down the progression of the disease. PRP represents a valuable tool in the management of knee osteoarthritis.
