What is the axis given for axial rotation of the knee joint? What implications does the location have for stress on the joint?
The axis for axial rotation of the knee joint is a vertical axis that passes approximately through the medial intercondylar tubercle. Increased stress on medial aspect of knee, more excursion laterally
