Smith+Nephew unveiled the CORI Digital Tensioner, a purpose-built device that allows surgeons to assess ligament tension in a knee before removing bone.
The CORI Digital Tensioner eliminates variability during knee balancing in surgery by enabling surgeons to assess joint laxity in the native knee and achieve precise ligament tensioning. This enhances surgical planning objectivity compared to other available methods.
The CORI Digital Tensioner applies a surgeon-defined, quantified force to the ligaments while distracting the knee joint and providing objective gap data for treatment planning and execution.
A brief clinical case series demonstrated a 64% reduction in tensioning variability with the CORI Digital Tensioner compared to a manual approach.
The CORI Digital Tensioner, which advances procedural innovation in robotic-assisted surgery, is a distinct technology that assists surgeons in resolving issues such as:
• The first and only ligament tensioning device used in robotic-assisted surgery to measure joint laxity in the native knee prior to bone resection. Gap data is automatically collected at a defined force across the whole range of motion.
• A real tensioning device with a software interface that enables surgeons to select their preferred target force value (50, 100, or 15010N).
• Dr. Bertrand Kaper of Orthopaedic Specialists of Scottsdale and HONORHEALTH Medical Group in Arizona recently performed the first commercial surgical procedure employing the CORI Digital Tensioner.
