This is common knowledge. Both retired pro soccer and handball players in my scandinavian countries almost all have a myriad of issues, most commonly and serious knee issues that require many operations.
I know several pro swimmers though and haven't heard of any serious issues there, so i guess it's from the impacts and constant running.
Heck, I'm Brazilian and it feels like 50% of males I know developed knee problem in their late 30s/early 40s
Almost all of them were weekend football (court, not grass) players. The others were week day players as well
Me, like the good nerd, I am developed back problems instead
