Abstract
INTRODUCTION
Post-cam dislocation in TKA is a rare complication after posterior stabilized TKA.
PURPOSE
Four cases of posterior dislocation of the tibia relative to the femur are described in one current posterior stabilized design.
CONCLUSION
Specific design features in one contemporary high flexion TKA design contribute to high dislocation rates.
