You have a persistent fever above 101 degrees for 2 days.
Your doctor may prescribe specific antibiotics to reduce the occurrence of
infection or the likelihood that it will spread to your prosthesis.
Reva's corner:
Whenever you have any dental work, any open wounds, etc., you need to contact
your physician so he can determine whether or not you will need antibiotic
therapy to prevent an infection from spreading to the new knee. This is something
that needs to be remembered forever!
If you are undergoing a surgical procedure and your surgeon plans to use a prophylactic
(preventative) antibiotic for the operation, there's no need to contact your
orthopaedic surgeon. If no antibiotics are scheduled, however, inform your
surgeon that you have an artificial joint prosthesis and that antibiotics
are generally recommended by your orthopaedic surgeon to protect the prosthesis
against injection.
Blood Clots (Deep Vein Thrombosis)
Usually by the third day after surgery - right about the time you're most
likely preparing to go home - you'll be placed on an anti-coagulant (blood
thinner) medication to help prevent blood clots from forming. The anti-coagulant
will either be in pill form or given as an injection.
Blood clots are the most common complication following knee replacement surgery.
Deep vein thrombosis means that a blood clot has developed, usually in your
calf, totally or partially blocking blood flow. Common initial symptoms include
pain, warmth and swelling in your leg.

What you can do to prevent blood clots:
* Do flex, extend and rotate your ankles at least every hour.
* Do wear your elastic stockings as ordered by your doctor.
* Do take an anti-coagulant medication.
