Posterior dislocation in total knee replacement: a price for deep flexion?
BACKGROUND
Post-cam dislocation in TKA is a rare complication after posterior stabilized TKA.


OBJECTIVE
Four cases of posterior dislocation of the tibia relative to the femur are described in one current posterior stabilized design.


CONCLUSIONS
Specific design features in one contemporary high flexion TKA design contribute to high dislocation rates.
