The Mobility Shot – PRF for Joints & Tendons

Move more. Enjoy more.

“PRF alleviates pain like a steroid injection, but without the side effects, and results last much longer!”  - Dr. Gustav Lo, MD

At RegenCen, we’re committed to getting you pain free.

Practically anyone over 40 may find their joints (especially in the knees, hips, hands, and feet) become increasingly stiff and painful with activity, or for no reason at all! Tissue inflammation, joint pain, and general age-related wear and tear are common issues in adults of all ages.

Whether it hurts to stand up or you dread the pain of a handshake, practically any arthritic joint, inflamed tendon, or other connective tissue can respond to platelet-rich fibrin therapy (PRF). The Mobility Shot uses all-natural PRF from your own blood cells to restore joint and tendon function, heal damaged tissue and reduce pain... especially for patients who suffer from arthritis or tendonitis.

At RegenCen in Traverse City and Petoskey, we offer treatments to revitalize your joints, easing pain and returning lost mobility and function.

What is PRF?

PRF (platelet-rich fibrin) is a product of your own blood - we simply draw your blood and separate the platelets and fibrin in a centrifuge. The platelets are full of growth factors and other cell-stimulating proteins; the fibrin holds the platelets in the area injected while they slowly release those growth factors.

How does PRF work?

The growth factors released by PRF attract stem cells (which grow into brand new cartilage and connective tissue) and fibroblasts (which produce more collagen for cushioning and elastin for flexibility). There is also an anti-inflammatory effect that works quickly, and a slower increase in blood supply to the area.

What other conditions is PRF used for and what about tendonitis and fasciitis?

PRF isn’t just for joints: orthopedists have used it successfully in many types of soft tissue injuries, from tennis elbow to plantar fasciitis and rotator cuff strain – there really isn’t a joint, tendon, or ligament where PRF (or its earlier, less effective cousin, PRP) hasn’t been studied and shown to work well, for both pain relief and actually healing injuries.

We can discuss your specific areas at your consultation.

What are the most common joints injected with PRF?

Knees, hips, and there’s been an uptick in visits for hand pain – using a smartphone or tablet requires repetitive motions that put stress on the joints and tendons in our fingers and wrists – especially the "texting thumb."

PRF can be a tremendous relief to this frustrating daily pain.

How does PRF compare with other treatments?

Recent research shows PRF (platelet-rich fibrin) injections alleviate arthritis pain as well as steroid injections, but in a much different way that actually rejuvenates the cartilage and other joint tissues, rather than causing further breakdown. And the results last a lot longer, often a full year or more.

The Mobility Shot treats:

  • Tennis Elbow
  • Golfer's Elbow
  • Bursitis
  • Tendonitis in the thumbs and hands
  • RSI (repeat stress injuries) in the hands
  • Plantar fasciitis ("heels spurs" in the feet)
  • Arthritis (osteoarthritis) of all limb joints

PRF for Joints and Mobility Issues
The Step-by-Step Process


There is very little preparation needed for a Mobility Shot. You will have a consultation with Dr. Lo in either our Petoskey or our Traverse City office to make sure that the treatment is appropriate for your condition(s) and mobility issues. Your health history will be reviewed, so bring a list of your current medical conditions and medications. Some imaging may be required and we encourage you to bring reports of any previous x-rays or MRIs to your appointment.


Come to the office well-hydrated – it makes the blood draw easier. We'll draw your blood to prepare the platelet-rich fibrin in a special centrifuge that separates platelets and plasma from blood.

The resulting platelet-rich fibrin is filled with growth factors we directly inject into your injured tissue. The fibrin structure keeps the platelets right where they are injected; the platelets then slowly release their growth factors.

We inject PRF using ultrasound guidance, which ensures precise placement of the PRF concentrate directly to the tissues that need repair.

Most PRF injections take 30-60 minutes, depending on the number of areas treated, and when your treatment is finished, you can leave the office immediately. Smaller joints tend to ache for a few days after the injections.


Dr. Lo will discuss your aftercare and additional activity modifications if necessary. PRF is noninvasive, so for many patients, all normal activities can resume.

Depending on your unique situation, we may advise additional forms of rehabilitation or treatment to help speed the healing of your damaged tissue.

Many patients begin to feel less pain and experience increased mobility within weeks after their Mobility Shot.
