A.I.O.™

Cutting guide

The U2 Knee All-In-One block is a revolutionary instrument that combines all the functions needed to perform external femoral rotation, sizing of the femur, antero-posterior adjustment of cuts, and preparation of chamfer cuts.

No more hesitating when choosing between femur sizes!

The A.I.O. block increases intraoperative flexibility in several ways:

  • Visual indicators provide references to the epicondylar axis and Whiteside’s line.
  • Choice of external rotation of 0, 3, 4, 5, 6, 7 degrees.
  • Meets both anterior and posterior reference concepts when sizing the femur.
  • Visualises the AP resection level throughout the process and allows consequent precise adjustments to be made.

The U2 Knee All-In-One block results in much easier cutting of the femur during surgery. “Fine tuning” solves the problem of which size to select when femur measurements are in-between sizes.
