Re: Knee Replacement
as long as you can walk and play and tolerate the pain and ache with some tylenol....do so....surgery like this is not to be taken lightly. It is major and has risks.
Most do very well with the surgery, others not so much. Part of it is the Dr, of course, part is the artificial joint and who made it and the biggie is the post op deal. Therapy is "un-comfortable"....the truth is, some days it hurts like hades. But you have to rebuild all the motion, strength and coordination. The sooner your Dr will let you up and around the better.
I had a friend who had both knees (some Dr will only do one at a time, now) done at the same time in October, and he was down hill skiing in Jan, and swore he was more comfortable with his new knees, than years with the original equipment.
Best of luck no matter what you decide.
