Arthritis Ruins Lives. Arthritis is a silent, insidious, and painful joint disorder that ruins many lives. In the United States, it’s the most common cause of disability. Around 50 million adults in the US have some form of arthritis. That’s 1 in 4 adults. By 2030, an estimated 67 million American adults are projected to have physician-diagnosed arthritis.
Our mission is to pioneer new orthopaedic treatments that accelerate healing, enabling people to stay active through research, development, innovation and education.
The Stone Research Foundation is an independent, 501(c)3 non-profit research institute pioneering regenerative orthopedic treatments to stimulate the body's own healing properties to reduce the suffering of sports injuries and arthritis.
We leverage small amounts of capital into important clinical and translational research and education. In our clinical research, we conduct outcome studies to measure the effectiveness of the biologic surgical techniques developed and utilized at The Stone Clinic. We conduct translational research to prove the scientific merit of new biologic approaches. We disseminate of the results of this research through presentation, publication, and education in order that others may benefit, and advance the standard of care in orthopedics.
