Regenerative Medicine

Regenerative Medicine describes innovative, outpatient procedures that use the patient’s own unique healing properties to provide significant relief of pain and improvement in function.

Hope Orthopedics of Oregon currently offers several procedures, including PRP Injections, EPAT shockwave therapy, Fluid FlowTM amniotic liquid allograft, and Tenex. Please note a consult is needed prior to performing these procedures.

Platelet-Rich Plasma (PRP)

PRP relies on platelets (cell fragments found in blood) and a variable amount of white blood cells to heal and repair injuries. This combination taken from the patient can enhance the body’s natural ability to heal, reduce inflammation in tendons and joints, and accelerate the repair of damaged tendons and ligaments.




PRP Therapy | Regenerative Medicine

What Does Platelet-Rich Plasma (PRP) Do?

Different types of PRP products are usually given as injections to heal and repair injuries. The job of platelets in the body is to help blood clot when there is an injury. The cytokines and growth factors that are in platelets can help repair injuries and encourage healing.

PRP Injections are used for a variety of sports injuries and musculoskeletal conditions including tendon injuries affecting the:

  • Ankle (e.g., Achilles)
  • Knee (e.g., “Jumper’s knee”)
  • Elbow (e.g., “Tennis elbow” or “Golfer’s elbow”)
  • Plantar fascia injuries (“Plantar fasciitis”)
  • Ligament sprains
  • Arthritis and meniscal injuries

How does it work?

Blood is removed from the patient’s arm using a needle into the vein. Then the blood is processed in a centrifuge, which separates blood components into different parts according to their density. The platelets are separated into blood serum (plasma), while some of the white and red blood cells may be removed. This process concentrates the platelets and produces what is called platelet-rich plasma (PRP).

How to prepare for your visit?

  • Avoid corticosteroid medications for 2 to 3 weeks prior to the procedure
  • Stop taking non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen, or arthritis medications such as Celebrex, a week prior to the procedure
  • Do not take anticoagulation medication for 5 days before the procedure
  • Drink plenty of fluids the day before the procedure
  • Some patients may require anti-anxiety medication immediately before the procedure


EPAT (Extracorporeal Pulse Activation Technology) is the most advanced and highly effective non-invasive treatment method cleared by the FDA. The technology uses the same shock-wave principles used for non-surgical treatment of kidney stones without the requirements of anesthesia. The technology is based on using pressure waves that stimulate metabolism, enhance blood circulation, and accelerate the healing process. Damaged tissue is able to regenerate and heal. The procedure is done in-office and takes about 15-20 minutes per session. Most patients will need 3 treatments, spaced about 7-10 days apart.

EPAT is recommended for:

  • Neck and shoulder pain
  • Back and chest areas
  • Foot and ankle pain
  • Upper and lower extremities
  • Myofascial trigger points

Benefits of EPAT?

  • Non-Invasive
  • Patients can return to normal activity immediately with no downtime
  • Safe, fast, effective, and affordable
  • Over 80% of patients have successful outcomes for long-term pain relief

BMAC (Bone Marrow Aspirate Stem Cell Concentrate)

BMAC is a component of your bone marrow that contains growth factors and anti-inflammatory proteins which have been shown to promote bone and soft tissue healing, as well as reduce symptoms of pain related to injuries, tendinitis and arthritis.

TENEX is recommended for:

  • Osteoarthritis
  • Ligament tears
  • Articular cartilage injuries
  • Advanced tendon injuries
  • Muscle strains or tears


BioLab Fluid Flow™ is an ambient temperature amniotic liquid allograft derived from the amniotic liquid within the placenta to support the repair of soft tissue injury by providing natural growth factors and other extracellular components to the injured area to promote healing, reduce inflammation, and reduce healing time.

Fluid Flow™ can help with degenerative joint disorders such as:

  • Sports injuries
  • Osteoarthritis
  • Joint pain

Inflammatory conditions such as:

  • Bursitis
  • Tendonitis
  • Fasciitis

Soft tissue injuries such as:

  • Ligament & tendon sprains
  • Muscle & meniscus tears

MACI® (Autologous Chondrocyte Implantation)

MACI® (autologous cultured chondrocytes on porcine collagen membrane) is made up of your own (autologous) cells that are expanded and placed onto a film that is implanted into the area of the cartilage damage and absorbed back into your own tissue.

MACI® is recommended for:

  • Repair of symptomatic cartilage damage in the adult knee

Tenex Health's minimally invasive technology can help eliminate chronic tendon pain by targeting and removing damaged tissue, without the need for conventional surgery. This patented procedure uses ultrasound imaging to identify the damaged tissue, remove it, and stimulate healing. The result is improved overall function and significantly decreased pain. Patients can recover in as early as 3-6 weeks.

TENEX is recommended for:

  • Tendonitis of the elbow, hip, knee, and ankle
  • Plantar fasciitis
  • Calcific deposit in the tendon
  • Calcific rotator cuff tendonitis

Benefits of TENEX?

  • Relief of chronic pain
  • Minimally invasive (no stitches required)
  • No scarring
  • Fast recovery time
