# What is the range of motion for a knee?

What is the range of motion for a knee? The knee works as a hinge and only moves in one plane of movement, flexion and extension. A knee that is completely straight will measure 0° and a knee fully bent will have a flexion of at 135° degrees. These measurements are that of a knee with a normal range of motion.

How long does it take to get full range of motion after knee replacement? Most of your improvement after a knee replacement will take time. However, the one thing that you must feel some urgency to accomplish is getting good range of motion of your knee (flexibility).
