What is the normal knee flexion ROM?

Explanation:
Knee flexion ROM is how far you can bend the knee from a straight leg. It’s measured from zero degrees at full extension up to the maximum bend. In healthy adults, full knee flexion is typically about 135 to 150 degrees, with 150 degrees often cited as the upper end of normal. So 150 degrees reflects maximal flexion that a normal knee can achieve. Lower values like 120 or 90 degrees would indicate limited flexion and possible tightness or stiffness, while 130 degrees sits comfortably within normal range but isn’t the upper limit. When testing, you’re looking for how far the knee can bend in a relaxed, pain-free athlete, and reaching around 150 degrees is considered full or near-full flexion in many standard references.
