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.


Open Platform

Supports a femur-or tibia-first workflow and is compatible with any major implant vendor.


No learning curve for registration with minimal time use.

Operating room with Intellijoint KNEE camera, software and device set up with artificial knee

Imageless and Pinless

Intellijoint KNEE doesn't require preoperative imaging and no pins are required outside the incision.

Angular measurements accurate to within two degrees1*


Accurate to within two millimeters1‡

What Professionals Have to Say

Allan Gross

“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.”
