In a healthy adult, knee flexion typically reaches up to how many degrees?

Explanation:
Knee flexion range of motion in a healthy adult reaches up to about 140 degrees. From a fully straight leg (0 degrees), the knee can bend to roughly 140 degrees, which supports many daily movements such as squatting, kneeling, and tying shoelaces. While there is some individual variation, 140 degrees is a commonly accepted upper limit for normal knee flexion. Values like 120, 100, or 90 degrees would indicate less than full, typical ROM. Therefore, 0-140 degrees best represents normal knee flexion.
