New Weekly Blog Feature: Ask Dr. C

By /

I wake up at about 5 am every day and begin writing. If I’m lucky, I had a great idea for the blog the day before and in between patient care or Regenexx CMO responsibilities, I got a chance to write a rough draft of that blog. If I’m not, then it’s figuring out an interesting topic from scratch. However, it occurred to me this morning, that my readers might like it if I could tackle a couple of questions that they have, in more depth, every week, rather than a random topic I pick. Hence, today I’m starting a feature to make that happen.

I often answer my own blog comment questions these days, which is something I started during the height of the pandemic, as I had more time. Now that I’m back in the office seeing patients I have a bit less time, but I really enjoy seeing what’s on the minds of patients, so I keep answering those comments. That means from several blog comments a day to dozens each week. Add to that the dozens of additional questions I answer each day in the office for my own patients. Hence, I know patients have loads of questions!

However, those responses are usually shorter form answers that I get to between patients or simple explanations that I can give to patients in the office. Hence, I need a dedicated place where I can spend a little more time answering those really common questions that come up all the time. In some ways that’s how this blog started, as I needed a place I could put all of my patient information rather than creating handouts.

I’ll start this feature with tomorrow’s blog post by asking readers to place your questions here in the comments below. You can ask anything you would like about regenerative medicine and orthobiologics. I’ll pick a few of those questions to answer as the subject of tomorrow’s blog.

In the meantime, I’ll get our web team to insert a widget in every blog post that allows you to submit questions at any time during the week to be answered on the weekly “Ask Dr. C” blog post. Also, take note that Dr. Jason Deitch and I are also answering your questions live every week on Facebook. That hour-long show is on Monday at 12 pm PST/3 pm EST on the Centeno-Schultz Facebook page (click here to be taken to that page) and on Fridays, at that same time, we’re on the Regenexx Facebook page (click here to be taken to that page). Those videos are indexed on those Facebook pages.

The upshot? Please leave your burning questions below to be answered on tomorrow’s blog. I want to create yet another place where you can get your questions about regen med and orthobiologics answered so that every patient feels heard and learns how to empower their own recovery!

    How can we help other providers begin to see the benefits of Regenexx? And, understand the difference in your care vs. the false providers?

  2. Ron

    What are your thoughts on specialized pro-resolving mediators (SPMs)?

  3. Randy Vernon

    Do you ever recommend not trying stem cell or PRP treatment for knee osteoarthritis & instead recommend knee replacement?

  4. Barb Riedberger

    Thanks for taking the time to share info! My question is regarding PRP booster shots after a successful Stem Cell treatment in one knee & successful PRP treatment in the other knee. At what point should I consider additional PRP injections? Should I get them with slight pain to stay on top of the healing or should I wait until really necessary?

    It might be well to distinguish again the difference between a positive corona virus test and more serious cases of this infection, and why this is so. The media treats them the same and they give the large numbers which makes the virus sound much more potent and destructive. And why are so there so many sub-clinical and mild cases to a potent virus that we have not had prior exposure to previously. Thanks

    I am confused about whether donated stem cells are living. I know of one prominent doctor who uses donated cells exclusively, eschewing bone marrow as the source. Please clarify whether donated stem cells will work.

    Hi –
    I had a Regenexx PRP treatment years ago for my low back, which helped, although of course my back has continued to age. I’ve been reading your blog since then. One thing I just read elsewhere, is summarized by this link:

    It appears these guys have developed technology – using existing FDA approved (for other uses) medicines, which prompts, and then stops, proper cartilage re-growth in joints.

    You guys might want to get informed about this, maybe try it out on an aged family pet or something, and then consider other ways it might improve your practices. It looks like a game changer.

      That drug is available, but has some pretty serious side effects (for which Medtronic has been sued). So far this is only an animal study.

  8. Anthony

    Has stem cell therapy been shown to have the ability to repair or regrow damaged cartilage even though cartilage has a weak blood supply. If so can you point me to studies that show results.

  9. Kristin

    What treatments are available for degenerative disc disease and is there an age where you cease to treat patients with these issues?

  10. Kent Lester

    Dr. C:
    Are you keeping up with the latest research into bone morphogenetic protein 2 (BMP2) and vascular endothelial growth factor (VEGF) which in combination, has allowed mice to regrow legitimate cartilage with skeletal stem cells?


    If so, do you think we’ll see the Cayman office experimenting with this approach in the near future?

    1. Chris Centeno, MD Post author

      Yes, this is only an animal study, so we are talking about it at our next research meeting.
