Infected knee treated by total knee arthroplasty.

The perceived wisdom in orthopaedics precludes insertion of implants in cases of post-recent active joint sepsis.

We illustrate the concept of using principles of revision surgery to successfully treat knees destroyed by primary staphylococcal septic arthritis.
