Hi. I have very recently been diagnosed with osteoarthritis of my knee. My gp said that impact exercise like running will make it worse. But I love to run. It's good for my mental and physical health. I was very upset at the idea of stopping running or reducing the mileage so I started looking for evidence. I need to weigh up the benefits of running with the possible consequences. I run about 20 miles a week, sometimes more (if my knee is good). Is there any good quality information that can help me with this? Many thanks.
