BACKGROUND A knee design with a ball-and-socket articulation of the medial compartment has a femoral rollback profile similar to the native knee. Compared to a conventional, posterior-stabilized knee design, it provides AP stability throughout the entire ROM. However, it is unclear whether this design difference translates to clinical and functional improvement. QUESTIONS/PURPOSES We asked whether the medially conforming ball-and-socket design differences would be associated with (1) improved… CONTINUE READING
