As for the general public, much of that is based on hearsay. However, there is more to this because many have experienced tendonitis from running. By the time I was 19, my left knee had gotten bad enough that I couldn't use it to walk up stairs and the most I could run was a half mile before it would stiffen up and I wouldn't be able to bend it (same effect from using it in going up just a few stairs). It once took me a month to be able to walk normally again after walking up three steps. So, yes, running caused my knee problem. And it lasted fifteen years until I got the right physical therapy exercises to get over it. So, there are solutions for such running-caused knee problems.
Ding ding ding ding!!
Am I and this guy the only two posters on this thread with a brain??
People, seriously, let's see if we can figure out why there is this disconnect between these research articles that come out every few years declaring " it is a MYTH that running is hard on your knees!" and the fact that many, many people including many, many runners believe it IS hard on their knees and DO have a lot of knee pain after running a lot.. HMMMMM...HMMMMM..
Eureka... I figured it out:
The research is discussing osteoarthritis which is the result of the wearing out of the protective **cartilage** in the knee. It appears that running is not harmful overall to this cartilage and may even help it remain strong.
The pain in one's knees that many many Runners experience is due to the stress on and damage to the **patellar tendon** , i e patellar tendinosis, i.e. "RUNNER'S/JUMPER'S KNEE." Also runners experience ITB syndrome which is due to a ligament issue. Neither one of these have to do with arthritis or damaged Cartilage.
Understand? The research is discussing something different/unrelated to the pain that MANY Runners feel in their knees from running a lot.
Sooo..the great myth that running is not hard on or stressful to one's knees is a myth itself. It's still is for most people at some point. it just doesn't cause osteoarthritis.
Get It??? Was that really so hard to figure out?
And Rojo, medicine is not broken but apparently your brain is if you couldn't figure out why there was this disconnect between most Runners experiences and the research.
Totally true in my experience. I've had multiple ortho docs(colleagues) tell me I'll need both my knees replaced in my 50s. It's incredible how even knee specialists believe such an obvious fallacy.
Very similarly I have been told by someone with a medical degree that even though the research and evidence strongly shows that running marathons is not related to higher incidence of cardiac deaths, she knows cardiac specialists who disagree.
It takes a while to grasp the significance of this, trained professionals are allegedly no better than complete lay people at understanding evidence and prefer their intuition.
