OUCH....

Knee injuries suck. it seems like they run in my family. My brother has had both operated on and he will eventually have to get a knee replacement but they won't do it until he is at least 50.

my sister had her knee operated on a couple years ago...

and I have arthritis in one and a tear in my ACL my cartilige (sp?) and the miniscus.... supposed to have surgery.... opted out of that lol.

But running is VERY hard on your knees. You don't realize until after it's too late just how much the impact tears them up.... that's not to say all runners end up with terrible knees.... but if your knees are bad it's likely running will aggravate them more.

Do you do strengthening exercises for your hips?

Hope you get better soon.
