What is the joint line angle of Journey II in the frontal plane?

• A. 3 degrees varus
• B. 0 degrees
• C. 1 degree varus
• D. 2 degrees valgus

Answer: (A)

In the frontal plane, the joint line angle describes how the knee’s joint line tilts relative to the leg’s vertical axis. Varus means the joint line tilts toward the midline of the body, while valgus tilts away from it. Journey II is designed to reproduce a slight varus alignment, about 3 degrees. This mirrors the typical native knee alignment for many people and helps restore natural ligament tension and knee kinematics after surgery, contributing to balanced stability and more natural movement. Other options would imply a neutral joint line (0 degrees), a smaller varus tilt (1–2 degrees), or a valgus tilt, none of which match the intended design. Therefore, 3 degrees varus best fits the Journey II specification.
