Platelet-Rich Plasma (PRP) Injection Therapy

Here at Oregon Medical Centers, we offer PRP injections as part of our regenerative medicine. PRP therapy is a regenerative injection that is used to promote healing of musculoskeletal problems such as arthritis, fractures, muscle injuries, tendon injuries, cartilage repair, chronic sprains, and ligament injuries. When you sustain an injury, platelets are activated in your body to stimulate the healing process and help build new connective tissue. Normally your blood contains 93% red blood cells, 6% platelets, and 1% white blood cells. In this therapy, the PRP doctor removes some of your blood and processes it to change this ratio to 94% platelets and 5% red blood cells (which are not as useful in the healing process). It is then re-injected to the injured part of your body to promote healing and stimulate tissue regeneration.

The Benefits of PRP Therapy

PRP injections have been used since 1987 to treat various conditions, and there are several benefits to this type of therapy: 

  • The procedure is minimally invasive, with short recovery time, and little to no scarring.
  • It is carried out under a local anesthetic avoiding the complications and side effects of a general anesthetic. 
  • The Platelet-Rich Plasma injection is natural, from the patient’s own body. No additives, chemicals, or foreign substances are used to prepare the final injection.
  • The certified PRP doctor can use it to promote the repair of both acute and chronic injuries.
  • Cartilage repair can be stimulated by PRP injections. 
  • They can help reduce inflammation, pain, and swelling while speeding up the healing process.


Who is PRP a Good Fit For?

PRP therapy is beneficial for people with certain musculoskeletal injuries, orthopedic conditions, or for injury repair in athletes. Examples of conditions that PRP injections can help with are:

  • Osteoarthritis
  • Chronic back pain, spinal disc, or joint disease
  • Ligament tears and sprains
  • Hand injuries, such as carpal tunnel syndrome
  • Shoulder injuries like rotator cuff tears
  • Tendonitis
  • Joint pain
  • Tennis or Golfer's elbow
  • Knee injuries, such as meniscus and ACL tears


Many PRP doctors utilize PRP injections in most parts of the body to help reduce painful symptoms and promote healing. In some cases, they may be used to delay joint replacement surgery or alleviate symptoms if there is a long wait for joint replacement surgery. 


What Does the Platelet-Rich Plasma Injection Procedure Involve?

  • The PRP doctor draws blood from the large vein in your elbow.
  • The blood is then prepared by spinning it in a centrifuge machine for about 10-15 minutes.
  • A local anesthetic is administered to the injured part of your body.
  • The platelet-rich plasma that has been prepared from your own blood is then injected into the affected area.
  • In some cases, ultrasound guidance may be used to ensure the PRP injection needle is directed to the correct place.


Although a minimally invasive procedure, it is normal to feel some mild discomfort at the injection site for a few days afterward. Your doctor will provide you with aftercare instructions following the procedure.
