Handheld navigation in total knee arthroplasty

Handheld navigation is now available for use in total knee arthroplasty, allowing for precision cuts of the distal femur and proximal tibia. By using inertial sensors and accelerometers, the handheld navigation unit is able to provide real-time, intraoperative information about alignment without additional incisions or arrays, line-of-sight issues, or the large capital expense associated with large console navigation systems. This handheld navigation unit reduces alignment outliers commonly seen with conventional guides, potentially leading to benefits in knee function and implant longevity.
