  • Surgical Demonstration: JOURNEY™ II XR with NAVIO™

    Dr Jimmy Chow (US).

    To view this collection, please login or join Education and Evidence.

    In this surgical demonstration video, Dr Chow performs a total knee arthroplasty using the JOURNEY II XR with robotic-assistance from the NAVIO Surgical System.

    The patient is a 52 year old competitive cyclist, who has had eight prior surgeries, mostly arthroscopically related. She has pain in all three compartments, with little deformity, mostly valgus that is getting in the way of her competitive cycling. Dr Chow shows how to use the NAVIO device to map out the bone and joint space in preparation for the replacement and joint alignment.

    The lecture continues the debate around outpatient joint replacement surgery. Dr Ritesh Shah (US) discusses his own experience on the current trends and advantages of outpatient programmes, including how refined techniques, medication and anaesthesia, with physical therapy, can help early mobilisation and predictability of outcomes. Dr Shah offers patient examples and tips on starting an outpatient programme, concluding with first-year results. Dr Shah is Chairman of the Centers of Excellence, Illinois Bone and Joint Institute. Filmed at the North American Hip and Knee Symposium, 2018.

  • UKA: Where Does It Fit in My Practice?

    Dr Reid B Brown (US).

    To view this collection, please login or join Education and Evidence.

    Dr Reid Brown (US) discusses the suitability and performance of unicompartmental knee arthroplasty in his practice, including criteria for choosing the right procedure and comparisons to total knee arthroplasty. He explains how UKA can be done as an outpatient procedure and how modern techniques have improved outcomes. Comparisons include kinematics, pain, blood loss, length of hospital stay and patient satisfaction. Dr Brown is Director of Joint Replacement at Baptist Health, Louisville, KY.

  • It Really Works: Results of a Kinematic Analysis

    Dr Steven B Haas (US).

    To view this collection, please login or join Education and Evidence.

    Dr Steven Haas (US) discusses the limitations of traditional total knee arthroplasty and the importance of matching anatomical contours to meet growing expectations of patients. He explains how JOURNEY II BCS knees have achieved near-normal kinematics, presenting other studies on mid-flexion stability, rollback ratios and range of motion. Dr Haas is Professor of Clinical Orthopedics at Weil Cornell Medical College.
