Shoulder Rotator Cuff MRI and IL-8: Yes Virginia There is a Santa Claus?

The concept that structural changes like a rotator cuff tear seen on MRI are causing pain is so ingrained into modern medical thought that doctors and patients alike believe this like a 5 year old believes in Santa Claus. Like the latter, however, the validity of the concept is highly questionable. Take for example a new shoulder…read more

Why Do Surgeons Still Perform Knee Arthritis Surgery?

As many readers of this blog know, there is little evidence that knee arthroscopy to “clean up” knee arthritis is effective. In fact, this type of knee arthritis surgery has been shown to be ineffective, yet it’s still performed.

Predicting Stem Cell Yields – Removing the Blindfold…

As I’ve blogged before, Regenexx is one of the few organizations that counts the number of cells in a stem cell harvest. This is mission critical, as this number represents a dose that our research shows can help make treatment decisions based on how many stem cells you have available. How can we improve on…read more

Fat vs Bone Marrow Stem Cells for Arthritis?

Way back in 2011, before most physicians had heard of stem cells, I sat down to look at the medical research on the comparisons of fat vs bone marrow stem cells for cartilage repair. These past several weeks, I’ve had a few doctors who have been trained at weekend stem cell courses ask me to send…read more

The State of Physician Stem Cell Education as Learned by Lecturing…

April – May is conference season where those of us that lecture nationally are on the road giving presentations at this meeting or that association. I’ve just returned from New Orleans having finished most of my speaking engagements, the last being later this month at Baylor College of Medicine. This morning’s blog is both about…read more
