Which feature of the JOURNEY II UK femoral component promotes compressive forces in deep flexion?

Explanation:
Divergent lugs shape how the posterior part of the femoral component engages the tibial insert during deep bending. As the knee flexes, this divergence widens the contact interface and keeps loading aligned with the compressive direction across a larger area. That combination distributes the force more as compression through the polyethylene and articulating surfaces, rather than concentrating it into shear or edge loading. The other features influence stability, impingement, or fixation, but they don’t promote the same posterior containment and congruent contact that diverging lugs provide in deep flexion.
