welcome to TE and surf on over to the getting to know you thread.

Cycling works for me

(is that like "hoocd awn fawnix werks fore me"? )

It's not so much gaining strength in my knees because your knees have no strengh, they are just a joint not a muscle. (is there a Dr. in the house who can explain this? Even a fishdr?)

What happens I feel and as my Orthopedic Surgeon explained is I gain strength muscles around the joint which supports your knee and in the end does some of the work my deteriorating ligaments and tendons used to do.

Also .... I lost weight therefore less pressure on the joints.

If you've seen x-rays of your knee you can see with that bone on bone thing? Less weight, less pressure.
