The JOURNEY II UK femoral lug diameter is how many millimeters?

• A. 6.9 mm
• B. 5.5 mm
• C. 7.0 mm
• D. 6.5 mm

Answer: (A)

The lug diameter is the width of the protruding lugs on the femoral component, a dimension that must match the instrument set and the bone preparation used for this knee system. For the JOURNEY II UK version, that specified diameter is 6.9 millimeters. This exact size ensures the instrument guides seat the component correctly and that fixation sits within the intended bone and cement/bonding space. If the diameter were smaller, there could be inadequate engagement and stability; if it were larger, it could interfere with bone structures or the alignment guides. The other close options don’t reflect the manufacturer’s specified dimension for this UK version, which is why 6.9 mm is the correct choice.
