Biomechanical Validation of Guidelines for Histopathology in Knee OA

    Wenzel Waldstein, MD, and his colleagues at the Vienna General Hospital, Vienna, Austria, recently completed the first study to provide biomechanical validation of the OARSI Osteoarthritis Cartilage Histopathology Assessment System [1] in knee osteoarthritis.

    Dr. Waldstein presented their work at the recent World Arthroplasty Congress, where he received 1 of 4 Free Paper Submission Awards honoring the top research reported at the meeting. The awards were supported by Medacta International.

    We asked Dr. Waldstein to describe the study’s methodology and results. Click the image aboe to hear his comments.
