@mabfp3 May I ask if you are in a lot pain daily? I have put mine off for about 3 or 4 years, too, but I tore my meniscus and then got OA on my kneecap...that's all...no pain unless I walk for awhile, then it goes away when I sit...the docs I've seen don't want to do a 'partial' and that's what I'd rather have since everything else is in good condition (worked out since my second child was born and he's 40 years old!) so not happy about taking out things that are still healthy!
