Caveat Emptor
1. I have done same day stem cell injections (twice) plus multiple rounds of PRP in my knees (torn ACLs, meniscus). It worked great. (This was not a Regenexx related facility.) Still skied and played tennis. 2. Due to concern about declining number of stems cell available via the same day procedure, I decided to try Regenexx Cayman cultured stem cell procedure. 3. Everything was professionally done. Cost for phase 1 was $10,500. 4. After cells were cultured, I was advised everything was good, so I booked hotel, air fare, etc to return for re-injection. 5. Ten days prior to my departure, I was advised that only 5 million stem cells were available and that I needed 30 million for the number of injections I needed on both knees. The doctor therefore did not want to proceed. 6. Stem cells were not counted prior to culturing so there was no way to know if I had any expansion. There was no known probability of whether another $10,500 bone marrow aspiration/culture would result in more than 5 million stem cells. 7. I therefore was left with no good way forward and was out $10,500 plus money spent on plane tickets. 8. The low rating is due to the lack of transparency/ expecatation management. When the count was known 4 months prior, I should have been contacted and advised of the issue. Moreover, one would think Regenexx would have an idea of whether a 30 million count is common, particularly for my age range. 9. The bottom line is I can’t recommend Regenexx Cayman due to either a lack of knowledge of metrics for stem cell counts and more importantly a failure to relay likelihood of one having the number of stem cells needed after culturing. If 5 million per round of culture is the likely outcome, I would have to pay over $60K and then the $12,500 for injections. 10. Maybe that is something some people will pay, but I decided to cut my losses and walk away. I wish FDA would approve cultured stem cells in the U.S. as I believe there would be greater rigor applied to the process. For now, caveat emptor.

We’re sorry this experience did not meet your expectations. It is clear from your review that your concern is not with the professionalism of the team, but with communication, timing, and expectation management around the cultured cell process. Regenexx Cayman is an independently owned clinic that is part of the licensed Regenexx physician network, and the clinic manages its own patient care and policies. We appreciate your feedback and regret that the process caused frustration and unexpected expense.
