What is the normal ROM for the knee?

Explanation:
Knee range of motion is about how far the knee can bend from a straight leg. In a healthy adult, full extension is 0 degrees, and the typical maximum bend (flexion) is around 135 degrees. That level of flexion lets you perform most daily tasks comfortably, like standing up, walking, and climbing stairs. Values well below or above this aren’t considered the standard normal for knee flexion; for example, 120 is a bit limited, while 150 or 165 would exceed the usual healthy range. Therefore, 135 degrees is the best representation of normal knee ROM.
