Knee Outcome Data for Cultured Stem Cell Injections

By /

We get asked almost on a daily basis, what can I expect as far as outcomes from a stem cell injection in my knee for moderate to severe osteoarthritis?  While we have begun to report large scale outcomes, an average outcome number like 55% patient reported improvement, at one year, means less to most patients. The issue is that it’s a difficult number to conceptualize (that number means that averaging in the failures with the patients that did exceptional, the averaged reported improvement was 55%).  However, here are some knee outcome numbers (mean about 1 year after the procedure) that make more day to day sense to patients:

For 126 patients reporting and 29 patients that failed to respond (drop out rate of 23%).  Approximately 75% of these patients were knee replacement candidates, 25% were knee surgery candidates to treat a solitary osteochondral lesion (micro fracture, ACI, MACI):

66.7% of patients are reporting more than 50% improvement

43.7% of patients are reporting better than 75% improvement

We are preparing this data for publication…

(Please note, these patients were treated with the Regenexx-C cultured stem cell procedure and not Regenexx-SD.  While Regenexx-SD does rely on the same stem cell type that was used to treat these patients and other clinics have reported good results using similar procedures that don’t rely on stem cell culturing, Regenexx-SD clinical effectiveness has not yet been established.)
