And I do kind of wonder how cumulative knee damage works. Thus far my knees have been pretty good, but it'd be nice to keep it that way.
I think it depends... the most likely I expect is cartilidge damage, which if you're careful will heal... cartilidge is after all a living thing and less dense that things like bone. Its basically working as a shock absorber. If
it gets a break and correct resources unless its really mangled it'll repair itself.
If you tear the cartilidge you've got a bigger issue. Depending on severity
you may have broken/rough surface on it, or worst case tear it from the bed
on the bone. In the former you can have your knee lock as you bend it, where the rough surfaces no longer slide over each other nicely. In the latter you either live with it, or they seem to open you up and just remove the
cartilidge altogether. Arthroscope off hand..
Only reason I know this stuff, is right behind Australian Rules Football, painting was the biggest industry requiring knee reconstructions, and early
on I noticed I was going to have to be careful with mine. If you have these kind of problems, anti-inflammatories will probably become your friend.
After that lot you can have ligament problems.. which basically means the
knee wil become loose... ergo you can pop it out or dislocate it, like a shoulder joint is common for. Or you can tear/rupture a ligament which is do not pass go, you require surgery to repair it, although if you're careful and not overly sporty you may be able to live with it, but watching what kind of stresses you put through it,lateral and/or twisting type motions become problematic.
