Abstract

A knee alignment measurement tool for use during a total knee replacement surgery may include the following main components: a sensor assembly, a display unit configured to power up, operatively control the individual sensors of the sensor assembly, and display the readings therefrom, and a flexible gooseneck cable operatively connecting the sensor assembly to the display unit. The sensor assembly may include a rigid base supporting a circuit board, a left sensor and a right sensor positioned adjacent to the left center, and a cover sealed to the rigid base to enclose the left sensor and the right sensor, wherein the cover does not abut the rigid base during the compression of the sensor assembly.
