Outcomes Data of Bone Marrow Stem Cells to Treat Hip and Knee Osteoarthritis

The purpose of this study is to determine if Bone Marrow Concentrate may be successful in
the treatment of osteoarthritis. Bone Marrow Concentrate is known to contain a community of
cells that has been shown to have "regenerative" properties. This study is designed to
evaluate the short-term clinical and x-ray outcomes of injections for hip and knee
osteoarthritis.
