Platelet-rich plasma (PRP) injections use concentrated components of your own blood to support the body’s natural healing process. While platelets are best known for their role in blood clotting, research shows they also release growth factors that aid in repairing and strengthening damaged tissues. In a typical healing response, the body relies on platelets to stimulate new tissue growth and injury repair. By increasing the platelet concentration at the treatment site, PRP therapy may help accelerate recovery. Although studies on PRP continue and opinions among medical professionals vary, many patients and providers find it a promising option for tissue repair and regeneration.

Conditions Treated with Platelet-Rich Plasma (PRP) Injections

PRP injections can be used to address a variety of orthopedic and non-orthopedic conditions, including:

  • Arthritis
  • Tendonitis
  • Bursitis
  • Joint pain
  • Ligament sprains or tears
  • Nerve inflammation
  • Post-surgical recovery from tendon or ligament repair

Beyond orthopedics, PRP therapy is also utilized to support faster healing after certain cosmetic and surgical procedures.

Benefits of PRP Therapy

PRP injections offer several advantages. Because the plasma is derived from your own blood (autologous), there is virtually no risk of cross-reactivity, immune response, or disease transmission. The treatment is minimally invasive compared to surgery, and unlike corticosteroids, PRP works by stimulating the body’s natural healing processes rather than simply masking inflammation.

The PRP Injection Procedure

The procedure begins with a small blood draw, which is then placed in a centrifuge to separate and concentrate the platelets. This platelet-rich plasma—containing up to five times more platelets than normal blood—is combined with a small portion of whole blood and prepared for injection. The solution is then carefully injected into the site of tissue damage.

Most treatments are performed with a topical anesthetic spray to reduce discomfort. While patients typically tolerate the injection well, some soreness or inflammation at the injection site may occur for 24–48 hours as the healing response begins.

Risks of PRP Injections

PRP injections are considered safe when performed under sterile conditions. As with any medical procedure, there are potential risks, including a small chance of infection, blood clots, or—rarely—allergic reaction.
