What is the posterior medial thickness of the Journey II femoral component in sizes 1-8?

• A. 8.0mm
• B. 9.5mm
• C. 9.0mm
• D. 10.0mm

Answer: (C)

The important idea is that the posterior medial thickness of the Journey II femoral component is set as a fixed dimension across sizes 1 through 8. This uniformity means the medial posterior aspect of the femur maintains the same thickness no matter which size you’re using, which helps preserve consistent knee mechanics, especially the posterior condyle geometry and how it interacts with the tibial insert during flexion. Keeping this thickness constant supports predictable flexion space and stable articulation across all sizes.

That consistency is why 9.0 mm is the correct value for the posterior medial thickness across sizes 1–8. Other numbers would change the posterior offset and could affect kinematics and contact in deep flexion, which the design aims to avoid.
