What is the posterior condylar thickness for Legion Femoral Component sizes 2-6?

• A. 9.5 mm
• B. 11.5 mm
• C. 7.0 mm
• D. 12.0 mm

Answer: (A)

Posterior condylar thickness refers to the thickness of the back part of the femoral component that articulates with the tibial insert, and it directly affects how far back the femur sits (posterior offset) and how the knee flexes. In the Legion Femoral Component, sizes 2 through 6 use a standardized posterior condylar thickness of 9.5 mm to keep the posterior offset and flexion space consistent across these sizes. This consistency helps maintain proper ligament tension and smooth knee kinematics through bending without risk of impingement. Therefore, 9.5 mm is the specification for those sizes. Other thickness values would change the posterior offset and are not used for sizes 2–6.
