Which of the following is a true statement about JOURNEY II UK's insert thicknesses?

• A. 8-14 mm
• B. 6-12 mm
• C. 4-8 mm
• D. 10-18 mm

Answer: (A)

The main idea here is understanding the defined range of tibial insert thicknesses available for the JOURNEY II UK knee system. The insert thickness is chosen to restore the knee’s joint height and to balance the soft tissues so the extension and flexion gaps are appropriate. JOURNEY II UK provides inserts in a specific set of thicknesses, from 8 millimeters up to 14 millimeters. This range is designed to cover the common variations in knee anatomy while keeping the ligaments properly tensioned and the knee mechanics balanced. Using a thickness within this range helps restore the correct joint height without overstuffing the joint or leaving the ligaments too loose. Thickness options outside this range are not the standard offerings for this system and could lead to suboptimal tension or motion. So the true statement is that the insert thicknesses for JOURNEY II UK span 8–14 millimeters.
