I mention my method but I'm not sure, I couldn't find the exact method in the literature. Please have a look at my method and advise me if possible?

Knee adduction moment:

1- After computing proximal shank segment net reaction moments by Newton-Euler equations, as this vector is stated in the Lab coordinate system, we should express it in knee joint coordinate system.

2- The axis about which the knee adduction moment is stated, is the axis normal to Y axis of the thigh segment (flexion/ extension axis) and Z axis of the shank segment (internal/external rotation axis).

3- This axis is stated in lab coordinate system. to have this axis in joint coordinate system, we cross producted the Y axis of lab in thigh coordinate system and Z axis of lab in shank coordinate system

4- Then moment vector is multiplied to this vector.

Proximal tibia shear force

1- After computing proximal shank segment net reaction forces by Newton-Euler equations, as this vector is stated in the Lab coordinate system, we should express it in shank segment coordinate system.

2- To do this, proximal shank segment reaction force is multiplied by the rotation matrix which express lab coordinate system in shank coordinate system.

3- First component of the resulted vector is considered to be anterior shear force.
