Full Knee Replacement

My brother is finally going to have his left knee replaced. He should have done it about 5 years ago but now it is finally so bad he can hardly step on it. He is scheduled to go in next week and have it done. He is going to feel so much better when he can walk again without falling. Also it will be so much better not to be in pain all the time, night and day. Cortizone shots are okay sometimes but when a knee gets as worn out as his is, they don't last but a short time. I will be happy for him when he is able to walk around good again.
