FEELING THE SQUEEZE: CURRENT DESIGNS OF FEMORAL ROTATION GUIDES FOR FEMORAL COMPONENT POSITIONING DURING TOTAL KNEE REPLACEMENT DO NOT MAINTAIN THE POSTERIOR JOINT LINE AND IN SOME CASES MAY RESULT IN FLEXION INSTABILITY

Introduction: The Trans-Epicondylar Axis (TEA) is widely used for rotational alignment of the femoral component during TKR. Conventional rotational alignment jigs have the rotational pivot point at the center of the distal femur. Most rotational alignment guides allow dialling up to 7 ⁰ of rotation.
