Stem Cell Therapy for Joint Pain at The Orlin & Cohen Orthopedic Group

Stem Cells

Stem Cells are the body's repair cells. New techniques allow us to harvest them for use in areas in need.

A promising alternative to surgery, this revolutionary procedure is done in less than one hour. Most patients experience marked improvement about five weeks after the procedure, helping you resume your daily activities relieved of joint pain.

Conditions We Treat

Stem Cell and Platelet Rich Plasma treatments are available for many conditions as a promising alternative to surgery.

Common Questions

What are Stem Cells?
Stem Cells are your body's repair cells.

What is Platelet Rich Plasma (PRP)?
PRP is a liquid concentrate of platelets. Platelets contain hundreds of growth factors that are very important in the healing of injuries. PRP is a newer modality of treatment for the management of many orthopedic conditions including sports injuries. RBC (red blood cells), WBC (white blood cells), plasma, and platelets are the major components of blood. Platelets are small discoid blood cells with granules containing clotting and growth factors, which are released during the healing process. On activation, the platelets accelerate the inflammatory cascade as well as healing by the release of the granules containing growth factors. Platelets have an average lifespan of seven to 10 days.

A normal blood specimen contains only 6% platelets whereas platelet rich plasma (PRP) contains a much higher concentration of platelets. A PRP injection is generally recommended in the treatment of tendon or muscle injuries with a success rate of about 70% to 80%. Four to six weeks may be required for complete healing.

Special precautions are required for individuals with low platelet count, bleeding disorders, those on blood thinning medications or anti-inflammatory medications, individuals allergic to local anesthetic agents, those with active infections and women who are pregnant or breast-feeding.

Where do we get the Stem Cells?
We harvest the Stem Cells from the fat around the belly. A small liposuction procedure is done and six to ten teaspoons of fat are removed. The fat is placed into a machine (a centrifuge) that separates the Stem Cells from the rest of the fat. We also draw blood. From the blood, we separate and concentrate the platelets using the centrifuge. We then add the concentrated platelets (PRP) to the Stem Cells and inject the mixture into the area in need. Five weeks after the initial procedure you will return for another injection of PRP.

How long does it take?
The procedure takes 15 - 20 minutes. It takes about 30 minutes to prepare the cells. It is done in the office using local anesthesia.

How long until I see results?
Most people notice improvement about five weeks from the date of the procedure.

What patients are saying…

Susan J.

My knee feels great!

I am 55 years old and I have suffered with knee pain for over 20 years. I have had meniscus surgery and I also have osteoarthritis. My knee would lock and get "stuck" multiple times a day and boy was that painful!

Any activity, long walks, dancing, and even gardening would cause excessive swelling and fluid. I was averaging twice a month to have my knee drained and I lived on anti-inflammatory medications.

I was blessed with the opportunity to undergo Stem Cell Therapy. Dr. Eric Price preformed the procedure in my left knee and six weeks later he did a PRP injection.

I am happy to say that I am 95/99% pain free! Dr. Price has restored the quality of life that I have been missing for so long.

This has been an amazing experience and I'm so very grateful.

Nancy D.

I can walk again without pain!

I was one of the lucky patients to take part in Orlin and Cohen's initial foray into regenerative medicine.

My right ankle, suffering from instability as a result of two fractures, received an injection of my own Stem Cells and Platelet Rich Plasma from my blood.

This was a last resort, having already had two rounds of lubricating injections a couple of years apart.

Now my ankle is 90% better than prior to the procedure. I have been walking, without any brace, anywhere from one to three or more miles a day without discomfort or swelling; before Stem Cell Therapy, this was not possible for me.

This procedure was a blessing and I wouldn't hesitate to recommend it for anyone with ankle problems. I am very thankful to Dr. David Zaret for both suggesting and administering it to me.

Paul D.

I almost can't believe it!

I sprained my ankles numerous times playing soccer and in 2007 had a lateral reconstruction and microfracture surgery to repair my damaged lateral ligaments and damaged cartilage in my talus bone.

Then, in 2010, I badly fractured both my tibia and fibula while skiing. This injury also required surgery, and resulted in 2 plates and 15 screws to hold my ankle together.

The Stem Cell procedure that Dr. Zaret administered has significantly reduced the constant burning in my ankle. I also have witnessed less swelling and greater flexibility in the joint. I am in a much better place and continue to improve.

Thanks Dr. Zaret for suggesting this treatment.
