Jerry,

I have always had bad knees, soft meniscus. In the mid 80's had to have lots of meniscus removed due to ski injuries. The last few years both knees bone on bone. Really sore and unstable, unable to make down to the river bank. 2 months ago had a total knee replacement on the right one. So much better. The operation/recovery was much easier than the horror stories I heard. Will have the other one done this fall, after the cataracts get taken care of. It sucks, this getting old stuff! Anyway my advice as others have said do the PT that is recommended and keep the muscles etc strong. Good Luck
