Goodbye joint replacements? Stanford scientists found a way to regrow cartilage and stop arthritis

• Scientists have identified a way to restore cartilage in aging knee joints, at least in mice, by blocking a protein whose levels rise with age.
• The approach not only reversed naturally occurring cartilage loss in older animals, but also protected mice from developing arthritis after knee injuries similar to ACL tears in people.
• The findings also showed promise in human tissue.
