There are a lot of factors in play here. His age, the blood thinners, etc. Even if he's doing well, I would hope they don't release him that quickly! He will most likely have a slower recovery this time, just because of he is 10 years older than the first hip. The older one gets, the more difficult recovery from a major surgery is. My mom is the same age as your dad. She had one hip replaced 10 years ago, also, and then the other one last summer. This recent one was painfully (no pun intended) slow. She's doing great now, but I really hate to think that they would "jump the gun" and release him so quickly. Will he be going to a rehab facility? That's a rough surgery, especially at that age! Good luck to him, and you. I know how you feel. I feel the same way about them getting out too quickly!
