Some doctors or dentist might say that it isn't necessary to take anitbiotics prior to dental procedures, but I will always to it. As I developed a staph infection in one of my knee replacements after a dental procecure. I am a believer in pre anitbiotic. I went through the removal with the cement/anitbiotice spacers for 3 months with IV antibiotic for 7 weeks and oral antibiotic for 6 months. At 3 months I had a new replacement put in.
One thing I would ask for at home if it is at all possible is a taller toliet. An ADA toliet makes a BIG difference if you are over 5' 5". I have had a total of 5 knee surgeries, 4 on the same knee and 1 on the other. After 2 surgeries I told my family I wouldn't come home until a taller toliet was installed. Makes a big difference.
