super hip and super knee surgery

My daughter, Olivia's, surgery is scheduled for early 2010 and i'm very nervous about it. Could anyone give me some information about super hip and super knee surgery. We have a fantastic doctor here in South Africa. We were hoping to bring Dr Paley to South Africa to perform the surgery, but due to exceptionally high costs it seems impossible. What i really need to find out is what can i expect before and after the surgery. How long is the recovery.
