Range of motion

The range through which the knee can bend and straighten (flex and extend).

A straight leg is said to zero (0) degrees of flexion. Full flexion is about 135-143 degrees, depending on the muscle/fat bulk of the limb.

Range of motion of the knee

Normally, a person can actually go beyond 0 degrees, and slightly 'hyper-extend', so full extension might be -6 degrees.
