Intellijoint KNEE

Foundational guide for successful total knee arthroplasty.

Fast, easy and accurate control

Intellijoint KNEE is a fast and easy-to-use surgeon-controlled navigation system that provides real-time measurements of your surgical cutting guides during total knee arthroplasty (TKA). Quantitative measurements of varus/valgus, femoral flexion and tibial slope angles, rotation and resection depth help you accurately align your cutting guide in the sagittal and coronal planes.

“Using Intellijoint KNEE™ gives me, my team and my patients' confidence intraoperatively. The quantitative measurements remove the assumptions associated with the varus/valgus, slope and depth resection position of intramedullary and extramedullary cutting guide instrumentation and set the remaining implant specific cuts up for success.”
