Claim Text:
1. A method of determining an anatomical feature during a knee procedure, comprising: coupling an orientation system with a distal aspect of a femur, the orientation system comprising a housing, a first orientation sensor and a second orientation sensor disposed within the housing, and a user interface operably coupled with the first orientation sensor and the second orientation sensor; wherein the first orientation sensor is selected from the group of sensor types consisting of: gyroscopic sensor, accelerometer sensor, tilt sensor, and magnetometer, and the second orientation sensor is selected from the group of sensor types consisting of: gyroscopic sensor, accelerometer sensor, tilt sensor, and magnetometer; wherein the first orientation sensor is a different sensor type than the second orientation sensor; estimating a first error associated with the first orientation sensor based in part upon the output of the second orientation sensor; estimating a second error associated with the second orientation sensor based in part upon the output of the first orientation sensor; moving the orientation system to collect data indicative of the anatomical feature relevant to the knee procedure; and reducing error from the data.
