Regenerative Medicine – Platelet-Rich Plasma (PRP)

There have been exciting developments made in the field of Regenerative Medicine. This includes the use of PRP (platelet-rich plasma), amniotic fluid, and stem cells to help build healthy discs, tendons, cartilage, ligaments, and bone. PRP, for example, is being used to treat injured or degenerative discs, joints, or soft tissues such as tendons.[1]

PRP is obtained by drawing blood, and then spinning it in a centrifuge to separate a concentrated layer of platelets from the red blood cells. This layer of PRP from the patient’s own blood is then injected into or around the injured site. The injection is carried out under ultrasound (US) guidance to ensure accuracy.

PRP contains growth factors and cells that enhance and strengthen the body’s ability to regenerate healthy tissue.

Tendon Repair

PRP has been used successfully to treat tendon problems at the elbow (lateral epicondylitis)[23], knee (patellar tendonitis)[4], Achilles tendinosis[15], shoulder (rotator cuff) when combined with dry needling (tenotomy)[6], and other areas, although the studies that look at the use of PRP to repair abnormal tendons do not all show positive results.

Joint Arthritis (Osteoarthritis) and Cartilage Defects

There is a growing body of evidence that supports the use of PRP in the knee and hip, and other joints to treat cartilage defects or degeneration[7-13]. This is a reasonable option to consider after physical therapy, analgesics, and possibly viscosupplementation injection with the cartilage building block / lubricant, hyaluronic acid.

Intervertebral Disc

There is exciting, early information from a study by Terry, Lutz, et al. [14] that shows positive results when PRP is injected into painful discs. The growth factors found in PRP may serve to stimulate regeneration of disc material[15]. Other regenerative options that are being studied include amniotic fluid[16], and there is good emerging evidence for the use of mesenchymal stem cells[17-19]

Muscle, Ligaments, Plantar Fascia

Information is limited or mixed for using PRP to treat muscle or ligament injuries[1], but there are studies that show promising results when used for the heel pain of plantar fasciitis[20].
