More orthopedic stem cell injection, patient reported outcomes…


KJ is a 76 year old white male who first injured his left knee in 1965 with a torn meniscus.  The medial meniscus was totally removed at that point.  He had multiple arthroscopies, the last being in 2002.  7 years ago he was told he needed a knee replacement.  On his pre-stem cell injection MRI he had significant loss of cartilage throughout his medial knee compartment and we placed him in the “FAIR” to “POOR” candidate (note the picture above-no meniscus on the left and a more normal appearing dark triangle on the right) .  Despite our pessimistic candidacy rating, he proceeded with an injection of his own culture expanded stem cells into that left knee.  His is now about 9 months out from his first injection.  Here are his comments:

“FYI, my left knee (the bad one) is coming along wonderfully well; it is actually better and stronger than my “good” knee!  And for that I thank you again!”

This patient was treated with the Regenexx-C (cultured stem cell injections). As always, not all knee patients can expect to get this same result.
