What is the typical knee range of motion for flexion?

The typical knee range of motion for flexion is generally recognized to be around 135 degrees. This degree of flexion allows for essential functions such as walking, running, and sitting, and it is considered the standard range for healthy individuals. Normal flexion enables the knee to bend sufficiently for various activities, and movements beyond this typically represent hyper-flexion or are less common in everyday activities.

In the context of human anatomy and physical activity, understanding the normal range of knee flexion is crucial for evaluating joint function, engaging in rehabilitation protocols, and implementing training programs that ensure joint health and mobility. A knee flexion of 135 degrees reflects the biomechanics of the joint during movements, reinforcing its importance in both health and fitness spheres.
