An estimated 30 million Americans are affected by osteoarthritis according to the CDC, and it is predominantly a disease of older age affecting more than 1 in 10 people aged 60+; with the aging population this number is likely to continue to rise steadily.
When cartilage naturally cushioning joints breaks down, osteoarthritis of the knee occurs, without this buffer bones can come into contact with each other causing pain, stiffness, and loss of flexibility.
Medications and physical interventions can ease symptoms of osteoarthritis, but currently there is no sure as it is not possible to regrow cartilage, once progressed to end stages the only option is surgical replacement of the joint. Stem cells were recently used to ease osteoarthritis in a small scale preliminary trial with promising results that will pave the way for more larger studies.
