Range of motion is typically measured using a tool called a goniometer. Normal ROM at the knee is considered to be 0 degrees of extension (completely straight knee joint) to 135 degrees of flexion (fully bent knee joint). Most functional activities require 0 to 117 degrees of motion at the knee.
Range of motion or ROM is a medical/anatomical definition not a mathematical one. The range of 180-360 degrees is not factored in, presumably because the lower leg cannot move in an entire circle! To measure degrees of flexion using the goniometer, the zero is on the ankle and the 180 on the hip. Thus full extension is 0 degrees.
