DH had his knee replaced Nov 23rd. He was high risk due to history of blood clots and diabetes and high blood pressure.
He did great! He was in rehab longer than expected because his leg was 'weak' from a stoke in 2008. They are working on building up muscles in the leg but the joint replacement was a total success.
The only advice I can give is if you need to lose any weight do so now. DH said he wants to lose 100 lbs before the next replacement. He's already lost 25 pounds just from being in rehab and working so hard on the leg every day. (And, he's back on his weight watchers program.)
Oh, and we had a great 'bonus'. He had not felt the bottom of his foot since the stroke. Now the bottom of his foot is very ticklish ... just an extra little bonus from God!
I will say the doctor prescribed all kinds of vitamins while in the hospital including some in the IV. It kept him very healthy!
