Healthy knee angles measured in motion: new study seeks early warning signs
NCT ID NCT05894551
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study measured the quadriceps angle (Q angle) in 130 healthy adults aged 18-25 to understand how it changes in different positions—lying down, standing, and during walking. Researchers used photos and video recordings to compare static and dynamic measurements. The goal was to identify early signs of knee alignment changes that could lead to future problems.
