ICJR Interviews: Outcomes of Revision TKA for Flexion Instability

    Flexion instability is a relatively new diagnosis following total knee arthroplasty (TKA), and over the past decade, as surgeons have learned more about how and why TKAs fail, it has been identified as the number 1 non-infection cause of early TKA failures.

    The literature on TKA failures provides good information on how to diagnose, evaluate, and manage patients with flexion instability.

    What’s largely missing from the literature, according to R. Michael Meneghini, MD, from Indiana University in Indianapolis, is data on patient outcomes following revision surgery for flexion instability, particularly in comparison with outcomes of revision TKA for traditional diagnoses such as osteolysis, wear, and aseptic loosening.

    Dr. Meneghini has added to the literature with this study, “Patients Improve Less after Revision TKA for Flexion Instability vs. Failures Related to Infection or Osteolysis” (Poster 187), which he presented at the 2016 Annual Meeting of the American Academy of Orthopaedic Surgeons in Orlando.
