    ICJR Interviews: Survivorship of a Unique Knee Design

    A unique implant design for total knee arthroplasty that incorporates external rotation has stood the test of time for the surgeons of the London Health Sciences Centre in London, Ontario, Canada, according to Richard W. McCalden, MD, FRCSC.

    The implant has been in use at the institution since 1996, and Dr. McCalden said the clinical impression was that even the earliest patients who received the implant were doing well.

    A retrospective chart review of more than 400 patients who had been prospectively followed for a minimum of 15 years showed this to be true: Overall survivorship was found to be 96%.

    Dr. McCalden and his colleagues also noted significant improvements from preoperative level to the latest follow-up in most outcomes measures, including WOMAC and Knee Society Scores and the Physical Health Composite Score of the SF-12.
