THE DIGITAL REVOLUTION
Current State of Total Knee Replacement
Knee replacement surgery ( TKR ) continues to be a successful treatment option for individuals suffering from osteoarthritis , rheumatoid arthritis or traumatic injuries . In 2023 , approximately 1 million knee replacements were performed in the U . S . alone . Because of an aging population and expanding indications , this figure is expected to rise significantly , potentially tripling , by 2030 .
Advancements in technology and surgical techniquealong with enhanced perioperative pain control , resulting in early functional recovery , have driven a shift to outpatient procedures . Some models predict that more than 50 % of knee , hip and shoulder replacements will be in the outpatient setting by 2026 .
Since its inception more than 50 years ago , the basic tenets of knee replacement have not changed , the goal being relief of pain and improved function allowing return to activity . This still involves

removing and replacing the diseased or worn articular portions of the joint . The technology of TKR however continues to evolve . Here are some of the current and future technological advancements available for modern TKR .
Robotic-Assisted and Image Guided / Computer Assisted Surgery
Image guided and robotic assisted surgery allow surgeons to perform procedures with a higher degree of reproducible precision . While there are a variety of systems available , they all share the common technique of using real time imaging and computer assistance to guide resection and implant placement taking into account an individual patient ’ s anatomy . Whether preoperatively or intraoperatively , this technology utilizes 3D planning based on the patient ’ s specific anatomy and can help optimize function of the joint . Intraoperative pressure monitors and motion sensors help predict and guide knee kinematics . This technology enables the surgeon to accurately map out the surgery , reducing the risk of misalignment , which can lead to short-term or long-term failure .
