We Invented Orthopedic Stem Cell Injections: An 8-Year Hip Follow-up

We invented orthopedic stem cell injections for arthritis. That’s a true statement, as while there were one or two physicians using bone marrow concentrate as part of specific surgeries before we began using stem cells, there was nobody injecting stem cells to treat arthritis. I was reminded of that this week when a patient who…read more

Does Hip Range of Motion Impact the Outcome of a Hip Stem Cell Procedure?

We have evaluated and treated hundreds of patients with hip arthritis with their own stem cells since 2005. One of the trends we’ve noted as doctors, is that poor hip range of motion may be a poor prognostic sign. Hip range of motion is lost quickly in many degenerative hip patients, so this has always…read more

Further Analysis of Regenexx-C Data

We’ve been re-analyzing Regenexx-C data for a scientific publication and came across some interesting observations. We’ve traditionally reported that hip arthritis patients tended to respond less often than knee arthritis patients to our cultured stem cell injections. However, when we take out patients with the bone disease avascular necrosis (AVN, also called osteonecrosis), a different picture emerges.…read more
