Prevention of Infection

While the risk of infection following knee surgery is relatively low, it's important to take the possibility seriously. Besides the surgical site itself becoming infected, it's also possible for infections in another part of the body to spread to the new prosthesis (sometimes years after the initial operation). Your nurse will normally review signs and symptoms of infection with you on the second day after your surgery.

Notify your orthopaedic surgeon if:

• Your incision site has drainage, redness, swelling and/or a foul odor. 
• You think that you may have an infection. This may include an ingrown toenail, bladder infection, skin sores, a tooth abscess, etc.
• You have increased knee pain at rest or when active.
• You undergo a procedure or have a condition through which bacteria might spread into your bloodstream.
• 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.

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.

** NOTIFY your nurse or doctor immediately if you have any of the above symptoms.
