Hi, thanks for writing to HCM.

This is just to let you know that REVISION KNEE REPLACEMENTS always yields less success rates when compared to primary total knee replacement.

Once an infection sets in after a joint replacement surgery, it is never going to be eradicated with antibiotics alone (however powerful they may be). So the only option is to remove the prosthetic components and put in ANTIBIOTIC SPACERS for atleast 6 months.During this period, he should also receive parenteral (I.V.) antibiotics. A number of tests have to be done afterwards to rule out persisting infection. A revision is to be planned after confirming that there is no focus of infection in the joint and elsewhere in the body.

This is the standard protocol for managing an infected total knee arthroplasty.

Hope this information is helpful. Good day
