Computer navigation for total knee arthroplasty has become increasingly popular because of its potential to improve the accuracy of placement of the femoral and tibial components1-4. However, complications related to the navigation system have only rarely been reported in the orthopaedic literature3,5,6. Ossendorf et al. reported on a femoral stress fracture that occurred after computer-navigated total knee arthroplasty7. This nondisplaced stress fracture occurred at the pin-hole site for the navigation trackers.
