Overweight?.

What a load of horse droppings. It's people like him that would not give up his seat on a train, even if you had bot legs in plaster and used a walker. So ignorant oand offensive

I agree that weight can account for some knee problems. I could lose maybe 10lbs but not overwieght. I believe its more heredity. My mother had knee replacements at around age 50 when they first came out. She was not obese. 

Yes, I am overweight. However, I only have problems with one near, two shoulders, and two fingers . . plus one ankle at the moment. while the knee and the ankle could be put down to overuse through overweight, I don't really thing that the same problem in the two shoulders and three fingers could be caused by the same thing. . .As the right knee is absolutely excellent, I have my doubts that the overweight was actually the cause of the left knee having problems.  As for the post op problems being caused by overweight, which is really more what your friend was referring to I think????  then morbid obesity could certainly make the post operative recovery more  difficult.  Let's face it, morbid obesity makes pretty much everything more difficult. 

He is wrong, I have many friends and aquantences who are not heavy or out of shape at all!  I have lost 75 lbs, and I am not considered heavy.  Some of my skinny friends have had more problems then heavy people.  So I do not go there!

I really think it is an insensitive comment for someone to make who probably has been lucky to not have physical things go "wrong."

I also have thin friends with knee and hip problems. Arthritis does not select only those who ate obese.
