FEATURED SURGERY: Revision TKA for an Infected Knee
Arlen D. Hanssen, MD, from Mayo Clinic, Rochester, Minnesota, operates on a 70-year-old male patient with an infected right total knee arthroplasty (TKA) in a procedure broadcast to attendees at ICJR’s 8th Annual Winter Hip & Knee Course.
Dr. Hanseen’s colleague, Matthew P. Abdel, MD, provides running commentary during the procedure, explaining what Dr. Hanssen is doing and why.
The patient’s primary TKA had been done at a different institution. When he presented to Dr. Hanssen’s clinic, he had highly elevated inflammatory markers: erythrocyte sedimentation rate (ESR) of 35 and C-reactive protein (CRP) level of 57.
Three months prior to the reimplantation procedure shown in the video, the patient received an articulating antibiotic spacer. Cultures grew Staphyloccocus capitis and he was placed on intravenous cefazolin for 6 weeks.
After a 6-week antibiotic “holiday,” his inflammatory markers had dropped to within normal limits – 4 for the ESR and <3 for the CRP – and the patient was scheduled for surgery.
