How does running influence joint cartilage?

[@colnoden]

Thank you so much for your insights! I have recently been diagnosed with moderate hip and back osteo arthritis and wasn't sure if I should continue running. My doctor said I could but I'm cautious as I don't want to make things worse. This video has helped me a lot in deciding to continue, but also to take care and allow my joints and muscles (and cartilage) time to recover after exercise.
