What is the typical range of motion considered full active knee extension?

Explanation:
Full active knee extension means the knee is straight with no bend at the joint. In goniometry, 0 degrees is the neutral, straight position, and any movement beyond that toward flexion increases the angle, while moving past straight into hyperextension would be recorded as a negative or beyond-0 value. So the typical range that represents "full extension" is exactly 0 degrees. The other ranges imply residual flexion or extension beyond neutral, which does not define full extension.
