Q. What are my chances of getting good pain relief if I have bone-on-bone arthritis of the knee or hip?
A. About 60% of patients with advanced arthritis get to the point where they experience at least 50% pain relief. This is the clinical criteria for a good outcome in most orthopedic surgery research. Anecdotally, the addition of a fat graft to the bone marrow treatment seems to increase the odds of getting good pain relief up to about 80%.
