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 Replacement 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.
Patient had presented well after the first surgery of the Staged Reconstruction. She was instructed to get an aspiration of the right knee in order to proceed with the next surgery to remove the antibiotic spacer and place a cement spacer. Results of the aspiration came back negative and patient proceeded with the next surgery.
Patient was advised to get another aspiration of the right knee to check for infection post-operatively. Results came back negative for infection and patient has subsequently had no pain, good range of motion, and weight bearing as tolerated with good relief.
The second stage of the surgery consists of implantation of revision components. The revision components differ from the primary components by allowing attachment of stem and bone augments. Modular components also offer semi-constrained and fully constrained bearing options.
