New Running Research on Knee Cartilage

This paper titled 'The Influence of Running on Lower Limb Cartilage: A Systematic Review and Meta‑analysis' is changing the way we think about cartilage and whether running is bad for your knees

At 0:50 the study showed that competitive runners had a 13.3% rate of knee and hip replacement. The controls (non runners) had a replacement rate of 10.2%. So you can overdo running, resulting in hips and knees as bad as or worse than non runners.
Although, recreational runners (presumably just light and occasional running) resulted in a joint replacement rate of 3.5%, which is what you focused on. And yes, it's a big improvement. But there is some truth that running is bad for you knees if you overdo it.
The question is: what is too much running? If you want to have the best chance of having good joints in old age, then don't run every day, and don't push yourself too hard. But DO NOT quit running. That's my take away from this.

Absolutely correct. And unfortunately the shorts don’t give me enough time to go into detail. This looked at prevalence of OA, not joint replacements and ‘competitive’ runners were defined as those who represented their country or were paid for running, so very top tier competitors. And yes they likely exceeded their capacity to the long-term detriment of their body. I have a good conversation with Hannah Dimmick on the podcast about it if you’re interested.

I lose count of how many non runners first response about me running is “doesn’t it damage your knees”?
