People paying thousands of dollars for stem cell knee treatment. But does it work?

Posted by

Across the United States and in at least one Canadian city, people are paying thousands of dollars for an unproven, same-day stem cell treatment to ease pain and restore flexibility in their arthritic or damaged knees.

The question is: does it work?

“We don’t have any really good, level one evidence out there yet,” says Dr. Shane Shapiro, an orthopedic surgeon at the Mayo Center for Regenerative Medicine in Jacksonville, Florida. “But judging by the proliferation of practices that perform the procedure and the number of patients that have it, many people are willing to jump in without knowing whether it will or won’t work.”

Dr. Shapiro leads a 25-patient clinical trial investigating whether the bone marrow aspirate concentrate (BMAC) procedure actually relieves pain and helps knees heal in patients with osteoarthritis. Over the past three years he and a team of researchers extracted mesenchymal bone marrow stem cells from patients’ pelvises, spun them in a centrifuge to a concentrated state and then re-injected them into one knee. The other knee, serving as a control for the experiment, got a placebo injection of saline solution. Patients then underwent magnetic resonance imaging (MRI) at six months and a year to see if the knee cartilage improved from its original inflamed state.

Mesenchymal stem cells are used because they can differentiate into bone cells, cartilage cells and muscle cells. They also have anti-inflammatory qualities, which could be helpful in treating osteoarthritis. The process is considered “autologous” because the cells are reinjected into the same person who provided them, as opposed to “allogenic” transplants that involve cells donated from another person.

Dr. Shapiro expects the results to be published soon. Meanwhile, clinics offering the BMAC procedure are popping up all over and charging between $1,800 and $10,000 per injection. ”Unfortunately, now you can take a weekend course or four-day course in how to do this,” says Dr. Shapiro. “I actually don’t think that all places that you can get this done are reputable, but there are some.”

What does the FDA say?

The U.S. Food and Drug Administration (FDA) has published draft guidance documents that reflect the agency’s current thinking about such treatments. At issue is whether the procedure constitutes more than “minimal manipulation” of the cells based on the degree of processing they undergo, and represents “homologous use” — meaning the cells perform their same basic function at the site in which they are injected. The draft guidance seems to indicate the BMAC procedure meets the criteria of minimal manipulation and homologous use,

When we sought clarification, the FDA’s  Center for Biologics Evaluation and Research wrote in an email that it “expects anyone involved with human cells, tissues, and cellular and tissue-based products (HCT/Ps), including stem cells, to familiarize themselves with the regulations; they are responsible for self-assessing how the appropriate regulations apply to their products.” It added that the attributes of “processing/manipulation and intended use must be carefully evaluated on a case by case basis.”

Health Canada, which takes a harmonized approach to that of the FDA, has not yet considered whether BMAC meets minimal manipulation or homologous use criteria. According to a statement from the Biologics and Genetic Therapies Directorate, “In some cases, autologous cell therapy products that are processed for a particular patient by a regulated health professional pursuant to the scope of their practice may not require federal pre-market regulatory authorization under the Food and Drug Regulations.”

In 2014 the U.S. Federal Appeals Court ruled in FDA’s favour in a case against Regenerative Sciences, a Colorado-based organization that until 2010 had been offering the BMAC treatment with cells that were extracted, cultured to make them more robust, and then re-injected into the patient. The organization now offers the treatment — called Regenexx-C (for “cultured,” a process that takes several days) — only at a clinic in the Cayman Islands, beyond the FDA’s jurisdiction. They continue to offer Regenexx-SD (for “same day”) at the Centeno Shultz Clinic in Colorado and at a network of clinics around the United States.

At a recent webinar, Dr. Christopher Centeno said that while “there are some additional regulations that may be coming out on stem cell therapies,” he didn’t anticipate that “any of those are going to change what happens here at Regenexx” and added that “right now there are no FDA guidelines for this type of work.”

The BMAC procedure should not be confused with stromal vascular fractioning (SVF) in which adipose (fat) cells are drawn from a patient by liposuction, run through a centrifuge to isolate the stem cells and then re-injected into the patient’s damaged knees or hips or shoulders. In fact, many clinics offer the treatment for a laundry list of conditions and diseases. Because SVF breaks down and eliminates the structural components of the adipose cells, it goes beyond the limits of minimal manipulation, according to the FDA. The agency has begun cracking down on clinics offering the procedure.

Here in Canada, clinics are offering BMAC procedures, says Dr. Jas Chahal, an orthopedic sports medicine surgeon with the Women’s College Hospital and the University Health Network in Toronto. “You can get it done. I’m not sure if you can get it across Canada, but there are people doing it in the Greater Toronto Area, for sure.”

Canadian study goes beyond BMAC

Dr. Chahal says more study is needed to prove whether the BMAC procedure is effective. “If you look at some of the articles presented at conferences, the basic science evidence shows that there could be a benefit — there are some anti-inflammatory molecules in there and there are some growth factors. I just don’t think it’s been adequately studied.”

Dr. Chahal and his team are midway through conducting a clinical trial that goes well beyond the same-day BMAC procedure. They are extracting the mesenchymal bone marrow stem cells from their patients and doing ex-vivo expansion (ramping up the number of cells in a lab) and then re-injecting them at concentrations of 1 million, 10 million and 50 million cells. “We’ve enrolled 12 patients and treated six so far,” says Dr. Chahal. “We expect to treat the next six in the next six months and should have data in another year.”

Should the Mayo Clinic study show positive results, Dr. Shapiro expects it could take some time for the BMAC procedure to become standard treatment for osteoarthritis. For one thing, there’s the cost.

“Someone has to pay for this,” says Dr. Shapiro. “If you’re going to be delivering it to millions of people, it has to come down in cost. It’s got to be more efficient and there’s got to be a system where it’s covered under either public or private health insurance, so that we could deliver it to the large number of people who need it.”

    The sooner the better as there is an epidemic almost in senior and young people who have osteoarthriitis and it’s really slowing me down, so it’s difficult to do move. Thanks, Doris.

  2. IDA M GULLIVER says:

    Thank-you to DR. CHAHAL-Canada, & DR. Shapiro USA for giving information RE knee stem cell transplant. Very informative & food for thought. I am a SENIOR. THANKS-AGAIN. God Bless. I G.

  3. Mark says:

    Any update on the effectiveness – I’m looking at options but frankly the literature is either marketware or carefully worded non-specific guidance. How are the trials going – is there any published data from them yet, even preliminary data?

    1. Joe Sornberger says:

      Thanks, Mark. We published a follow-op on the results of Dr. Shapiro’s clinical trial in September and you can see it here: As you’ll see, the results were inconclusive. As for Dr. Chahal’s trial, they have now reached full recruitment and hope to have the results out sometime in 2017.

      1. Anjana Allen says:

        Thank you for your advise. Do you know when in 2017, Dr Chahal’s research will be available?

        1. Joe Sornberger says:

          In my last conversation with Dr. Chahal they had recruited all the 12 patients needed and were gathering the data/results. Not sure when they will be out this year. but we will be following up with his team.

  4. John Sturtz says:

    All these nebulous conclusions make me wonder if this therapy works. I’m hesitant to spend the money if I’ll need knee surgery in another six months. The field is full of heavy handed marketing. Is there any anecdotal evidence from any of you that this therapy worked significantly?

    1. Joe Sornberger says:

      Thanks for the comment. Anecdotal evidence should be taken with caution, as people who have paid money for treatments are, essentially, invested in it. And often people who get placebo treatments consider their conditions have improved.

  5. Pam says:

    Looking into this and a few things come to mind, the first being that if the stem cells used are from adipose tissue the whole procedure is done on an outpatient basis taking 2-3 hours so why the enormous cost of several thousand dollars?

    Also, since the doctor I first heard about doing this was reporting success using adipose tissue, why are at least some now going after bone marrow stem cells instead? Isn’t that a much more potentially problematic source?

    It seems to me that the apparent simplicity of using (especially adipose) tissue stem cells should be a procedure easily available on a sliding scale, only ending up with knee or hip replacement as a treatment of last resort rather than the preferred choice by doctors.

    Since arthritis is now virtually an epidemic especially with seniors, using the easiest and least intrusive treatments first which offer the possibility of relief seems highly sensible from all aspects, even surgery and knee or hip replacement is not 100% successful for everyone and surgeries have their own risks.

    1. Joe Sornberger says:

      Thanks for your comment. Clinical trial evidence is lacking regarding the effectiveness of adipose-derived stem cell transplants and limited for bone-marrow-aspirate concentrate. Please see results of the Shapiro study at: http://journals.sagepub.com/doi/abs/10.1177/0363546516662455

  6. maxine says:

    Are there any clinical trials offered in New York at the present time?

    1. Joe Sornberger says:

      Thanks for your query, Maxine. I don’t know of clinical trials underway in New York. I did a quick scan of clinicaltrials.gov and came up empty-handed. There are no results yet from the Toronto trial, but they may be out later this year.

  7. Sandra Gushta says:

    What are the steps one has to take to get this procedure done ( stem cell knee injections) ? I would like to have this done instead of having to go through knee replacement in a few years.

    1. Joe Sornberger says:

      Thanks for your comment, Sandra. This kind of treatment is still unproven. Please see our follow-up blog post.

  8. Lisa says:

    Are there any trials in Oregon?

    Did you address the “why so expensive” question?

    Thank you!

    1. Joe Sornberger says:

      Thanks for your comment. We published a follow-op on the results of Dr. Shapiro’s clinical trial in September and you can see it here: http://stemcellfoundation.ca/en/2016/09/20/jury-still-out-on-bmac-treatment-for-knees/?hilite=Shapiro
      As you’ll see, the results were inconclusive. We are unaware of randomized controlled clinical trials in Oregon and not qualified to comment on expenses.

  9. Tanis O'Callaghan says:

    I I have had a cartilage replacement procedure in mind for a few years but didn’t know where to get it. I know an artificial cartilage replacement has been invented by a group of Irish scientists from Trinity College, Dublin. This made the news recently when it proved highly successful with a fine racehorse. Can it be used on humans? If not where could \I get stem cell replacement to grow cartilage in my knee? Also what would it cost?

    1. Joe Sornberger says:

      We published a follow-op on the results of Dr. Shapiro’s clinical trial in September and you can see it here: As you’ll see, the results were inconclusive. I have not heard of artificial cartilage replacement so I cannot comment. We expect to publish more on BMAC transplants in the coming weeks.

  10. Cindy says:

    Are they recruiting any more patients for the Toronto trial
    Are there other trials available elsewhere in Canada ?

  11. Jean says:

    I would like to be updated about stem cell knee replacement. I live in Toronto and considering knee replacement for my second knee.

    1. Joe Sornberger says:

      We published a follow-op on the results of Dr. Shapiro’s clinical trial in September and you can see it here. As you’ll see, the results were inconclusive. We will be publishing more on this in the coming weeks.

  12. Adam says:

    Thank you for publishing this article. We’ve heard a lot of mixed things on stem cell knee replacement. Hoping that the FDA can stay on top of all of the new developments!

  13. Jan Risberg says:

    I had stem cell injection in one knee last November. So far (just over three months in) I see a small improvement compared to the other knee particularly at night (when the legs have been at rest for some time), the injected knee has no pain when I get up but the other one can sometimes be locked with severe pain. Before the injection both knees had severe pain at night. The cartilage in both knees were shown on Xrays to have about half worn away. I have an appointment with the doctor who did the injection at six months and will be able to tell more from then on. I understand from what I have heard it might take six months or more for this to show improvement? Not sure about that.

  14. Dane says:

    There is in fact a large body of published research on the use of stem cells for treating osteoarthritis. A group of doctors in Spain (Vega et al) published a RCT in 2015 that used cultured bone marrow stem cells to treat knee OA, with MRI evidence of cartilage regeneration at one year. Multiple other studies have been published by this same group of Spanish doctors (Soler et al, Orozco et al). Take note that Dr Shapiro’s BMAC study is done without culture expansion of stem cells, meaning that his patients were treated with a stem cell dosage that is smaller by several orders of magnitude. This is true for all clinics in Canada and the US. Dr Chahal on the other hand is using culture expansion for his study, so his results will likely be impressive, but realize that he is far from the first to do this.

  15. Gino Smecca says:

    I’m based in Toronto and have a meniscus tear in my left knee that has not been presenting any symptoms unless I run, so I stopped running. Lately however, it has been moderately painful while walking. All my research suggests that scoping may not provide any relief. I’m very interested in Dr. Chahal’s trial and results.

  16. Samuel S. Williams says:

    Have been to StemCellCarolina seminar in Charlotte, NC. Holly S. Schmitt is the acute care nurse practitioner there. Would like to have the most current realistic evaluation from Joe Sornberger, who seems to be on top of the issue. I am 82 and my doctors seem to think I am beyond the age range for benefit. Was a 25,000 mile runner in my “middle age.” Keep me fully up to date. Sam in Charlotte

  17. Vaish says:

    Can autologous stem cell therapy be effective for patients awaiting Total knee replacement. Is this therapy meant for/ better for earlier stages of the disease rather than the very late ones. I am 65 years old female.

  18. hem says:

    I’m just wondering the chances of forming tumor when using Mesenchymal stem cells? Could you throw some light on it? If not curing the disease, does it have any side effects? As I heard stem cells live very short time but I read they could cause tumors after 5 to 6 years. Is it true? Thanks.

    1. Sue DeLisle says:

      Hem,
      Researchers are working to create fail safe transplant methodologies to ensure that stem cells turn off before causing harm. For more information, please link to the International Society for Stem Cell Research Web feature Considering a stem cell treatment? at http://www.closerlookatstemcells.org/.

  19. Linda Dekle says:

    Emory medical in Atlanta is providing this procedure if they consider one a good candidate. 75 to 80% success rate. Not a clinical trail. At present $5,000 total for both knees
    .

  20. Pauline Martin says:

    I am very interested in the stem cell as I have severe arthritis in both knees. I had arthroscopy to clean them out and get Synvisk injections every 6 months to postpone knee replacement. Being a tennis player, knee replacement is out of question unless necessary. I’m only 57 years old so hopefully there will be a solution very soon. I am very healthy and fit.Living in Canada but i’m willing to go anywhere!

  21. Evelyn Weeks says:

    I had my own stem cells injected in both osteoarthritic knees mid January 2017. This was at the Capri Clinic in LaCombe Alberta. The results are fantastic. After two weeks no pain in either knee, and now I can walk several hours and ride my bike. I am over 70. Before these injections I had a lot of pain, hated walking as every step hurt. I certainly recommend what the Drs. at Capri Clinic did fo me. Cost was very reasonable too.

  22. Alina says:

    Hello,

    I have the problem with my both knees, no cure for that, and my life is ruined. I had two shots of PRPs in my knees, no help, but I had a lot inflammation after that.
    Now, I am very interested about Lipogems -stem cell from adipose tissue.
    Are there in Canada any trials using this method?

  23. I SUFFER FROM AUTO IMMUNE ENCEPILITIS AND WAS HOSPITILAZED FOR 6 MONTHS DURING 2016. I WAS FIT ANS HEALTHY BEFORE AND IT CAME ON OUT OF THE BLUE. NOW, SINCE I AM OUT OF THE HOSPITAL I STARTED GETTING LOWER BACKACHE ON THE LEFT SIDE WHICH HAS TURNED INTO FULLY BLOWN SCIATICA. LAST WEEK I ATTEMDED A SEMINAR ON STEM CELL TREATMENTS AND FOUND THAT ONE OF THE SUBJECTS THAT WERE MENTIONED WAS SCIATICA. I AM SEEING MY NEUROLOGIST ON WEDNESDAY THE 7TH AND AM VERY INTRESTED IN WHAT HIS OPINION IS GOING TO BE. … PLEASE TELL ME IF THE STEM CELL THERAPY IS WORTH WHILE…

    KIND REGARDS, BRENDA.

  24. Deborah Montgomery says:

    I am having a knee replacement in my left knee,and wanted cell in the right knee which is not as bad. Can I get them at the same time.

  25. Al O says:

    I have contacted Regenexx in Toledo, Ohio about getting both knees done, my left is worse than the right. I’m 89 years old but in good shape. They want $7500.00 to do the job but are playing games with getting an appointment. Possibly hesitant because of my age??

  26. Al Osada says:

    I have one knee that has damaged cartilage and the other just has some Arthritis that I’m told is not too bad. I’m able to walk without too much pain but cannot normally walk up the stairs. I’m 89 years old but have worked out physically most of my life so am in pretty good shape. I hear pros and cons about stem cell therapy and would like to know if anyone has any positive or negative information for me.

  27. Al Osada says:

    I am still able to walk but can’t do the stairs in a normal fashion. One knee is worse than the other and I’ve done research on Blood marrow stem dell regeneration and would like to know if anyone out there has had it done and what the results were.

  28. Tammy Wilkinson says:

    Is it still possible to become involved in the clinical trials in Toronto? I suffer from severe osteoarthritis and am on several medications. I’m only 42 and my surgeon said that he would not do a knee replacement for at least another ten years.

  29. Edgar G. says:

    I myself have been in rouch with CAPRI Clinic in Lacombe. They say their results are positive for about 60-70% of their patients but it is all anecdocal. They don’t have any technical proof. Their costs are reasonable, but they don’t go through the process which increases the number of cells.

    I need a hip replacement urgently by my doctor’s recommendation, going by the X Rays which show bone on bone. BUT I HAVE NO PAIN … My common sense says that all this was what actually wore away the ligaments. But what do I know…?

  30. NK Sharma says:

    I see there only the questions AND no response or amswers from patients who have undergone the stem cell treatment in place of knee replacement surgery

  31. Dan says:

    I’m 42 and I have bi lateral torn labrums and severely destroyed hip cartilidge. I am searching for a way to put off surgery as well. I have looked at placenta donor vers adipose fat. I suppose the fat might be better coming from your own body but I do like the prospect of not having to get lipo auction to get it out. I’ve read some articles about not knowing how to control what the stem cells create. Some say there is a chance of them creating anything from a tumour to extra bone. It’s too bad it’s not well known yet because I need the treatment asap. I have also heard PRP alone might be very helpful.

  32. A 75 yr old. Female would like to connect with patients receiving stem cell treatments @ Capri clinic in Lacombe, or anyone receiving stem cell trials in Calgary.

  33. Rick says:

    Just received call from a central AB clinic to rate any change in pain levels from 1-10 after 3 mo.stem cell treatment period. Mine is still high, no relative change. Was told could take up to six months or more to notice any progress and each case is subjective.Still hoping for the best but whole process seems hard to determine what is considered success i.e. is a pain decrease from an 8 to 7or 6 considered success?

    Hy my name is carlos i have been with cronic pain in mu hip, because i have osteoarthritis for over 10years so bad that i had to stop work, and applied for wefare. Pain is gating very bad. Please is there any way that you can help me so i could ga back to my normal live!!. Thank you very much. Carlos A. C.

  36. Yacon Root says:

    Great Blog. Really enjoyed reading.

  37. Mavis Garland says:

    Great site, although not many positive outcomes about stem cell treatment to date.
    So many looking for relief…I hope a breakthrough will come soon.
    I too, hare severe osteoarthritis in both knees…so hope for good news on stem cell or something new to come through for all us knee sufferers so we can enjoy the rest of our lives.

  38. Great site. I need knee replacement surgery. I have severe osteoarthritis in both knees. I’m soon to be scheduled for knee replacement surgery. I’m willing to participate in a study on stem cell research to avoid this surgery. Thank you very much. Muriel M.S.
