Patient is a 55 year old female who came in with pain in the right knee. Patient stated that she had a right Total Knee Arthroplasty (TKA) a few years ago at an outside institution. Patient presented with severely restricted range of motion and was in severe pain.

She was advised to get an aspiration and to follow up to review the test results. Results showed that she had an infected right knee prosthesis, and the patient was advised that the best option would be a Staged Reconstruction with Antibiotic Spacer placement.

It was explained to the patient that this would entail two surgeries. The first surgery would be to remove the hardware of the previous TKA and place the antibiotic spacer.

The second surgery would be remove the spacer and put in a cement placer replacement. All alternative options and risks were thoroughly discussed with the patient.
