conditions for stem cell therapy of the knee?

[rayrockwood]

Hello all,
I’m new to the board and see that many of you have had stem cell therapy for cartilage damage and I was wondering if any of you know if having regular prp therapy w/o out stem cells before a stem cell procedure would negate the effectiveness of subsequent prp/stem cell combo therapies. As of this moment my insurance covers prp but not stem cell therapy and I’d like to have it but don't want to lessen my odds of having a successful combo therapy as that is my long term plan. Thanks
Ray
