Main difference is constrained device(ActivL) versus non-constrained or semi-constrained(M6). Also, alloy materials. CoCroMo (Activ) versus titanium(M6).

Movement is different also on axis of rotation.

Default Activ L & M6 L difference

Drewrad,
Thx for you posted response.

So if I understand your post it would mean constrained motion within the degrees of motion of the disk?

M6 constrains on axial rotation and has translation on forward flexion as well as extension and is not 'locked into' a path of travel.

Activ L has an insert which allows for translation but is locked into a path of travel.
