    Primary Total Knee Arthroplasty Using Computer Navigation

    Editor’s Note: Throughout January, we’re giving you a chance to get reacquainted with tips, tricks, and techniques from leading orthopaedic surgeons as we present the best of the best from our collection of surgery videos.

    Watch J. Craig Morrison, MD, from the Southern Joint Replacement Institute, Nashville, Tennessee, perform a computer-navigated total knee arthroplasty on a 67-year-old female patient with left knee pain that has not responded to conservative treatment in a procedure broadcast live to attendees at ICJR’s inaugural Emerging Technologies in Joint Replacement course.

    The patient is a retired circus performer who injured her knee 10 to 15 years earlier. Multiple non-operative therapies were attempted to alleviate the pain – including non-steroidal anti-inflammatory drugs, corticosteroid injections, viscosupplementation, platelet-rich plasma, prolotherapy, and stem cells – but all failed to provide lasting results.

    On presentation, range of motion of the knee was 0° to 115°. Radiographs showed slight correctable varus alignment, joint space loss in the medial compartment, osteophytes, patella Baja, and patellofemoral disease.
