The design and preliminary assessment of a new knee ligament arthrometer

摘要

The paper introduces a new knee ligament arthrometer with dual functions. The arthrometer provides not only the traditional function to test the laxity anterior/posterior cruciate ligaments, but also the function to test the laxity of the medial/lateral collateral ligaments. The preliminary assessment about the data reproducibility was conducted. It showed that the new arthrometer performed well in the aspect of data reproducibility. Further assessment of the arthrometer will be conducted, and the reliability need to be established by comparing with the existing arthrometer.
