title: Tibial intramedullary alignment in total knee arthroplasty.
abstract: This article describes a study that assessed the accuracy of a tibial intramedullary alignment device in 44 adult cadaveric tibiae. The results suggest that greater accuracy is achieved if the device is inserted fully to the level of the distal epiphyseal scar and if used in the nonvalgus tibia. When seating of the tibial guide rod is incomplete or when the tibia has a valgus anatomic bow, cross-checking with extramedullary alignment devices is recommended to maximize accuracy of tibial component position.
