FEATURED SURGERY: Unicondylar Knee Arthroplasty

    A 58-year-old female patient who had already had a unicondylar knee arthroplasty (UKA) of her right knee undergoes a left UKA in a procedure performed by William G. Hamilton, MD, from the Anderson Orthopaedic Research Institute in Alexandria, Virginia.

    The patient has had left knee pain for several years and has failed a course of conservative treatment consisting of non-steroidal anti-inflammatory drugs, physical therapy, and knee injections.

    Radiographs show osteoarthritis confined to the medial compartment. According to Dr. Hamilton, the lateral radiograph of a candidate for UKA should show:

    • Competent anterior cruciate ligament (ACL)
    • Joint space in the posterior medial joint
    • Lack of excessive rollback or wear of the posterior medial tibia

    The patient’s prior UKA of the right knee was done in 2006. That procedure was done with a concomitant ACL reconstruction; Dr. Hamilton’s sports medicine partner did the ACL reconstruction to repair a torn, unstable ligament.

    For the left UKA, Dr. Hamilton’s patient is prepped with a spinal anesthesia and sedation. She also has an adductor canal block for postoperative pain management.

    The procedure was broadcast to attendees at the 8th Annual Winter Hip and Knee Course.
