I've had a tear, but not as bad as the ones above. It would catch sometimes if I did a deep knee bend. Very painful when that happens, like pinching a nerve. My ortho said he could repair it, but there would be a long period of rehab, or I could leave it as is if it doesn't bother me too much. It was pretty minor as far as tears go, so I opted to leave it. It bothered me every now and then for the next 3-4 years, but eventually it went away. It's been a few years since it's bothered me at all.
