How One Surgeon Manages an Infected TKA

    No single, off-the-shelf solution can be used to treat a patient whose total knee arthroplasty (TKA) has become infected – too many variables and complications are involved:

    • The patient’s health status
    • The infecting organism
    • The quality of the soft tissue
    • Bone loss
    • Ligamentous integrity

    Arlen D. Hanssen, MD, from Mayo Clinic in Rochester, Minnesota, takes these key considerations into account when planning surgery for a patient who presents with a suspected TKA infection.

    Although his approach is tailored to each patient’s needs, Dr. Hanssen’s philosophy is to always plan for a two-stage procedure. This allows him to more successfully eradicate the infection without “burning a lot of bridges with soft tissue and bone,” which he says would occur in a one-stage procedure.
