Does Medial Knee Position Reflect Dynamic Knee Valgus? Comparing Kinematic Timing and Magnitude During a Three-Task Movement Screen

The authors aimed to investigate the relationship between medial knee position and dynamic knee valgus by analyzing the timing and magnitude of knee abduction during various movement tasks in adolescent female volleyball players. Their findings indicate that while medial knee collapse occurs before maximum knee abduction in certain tasks, the two-dimensional assessment of knee position does not fully capture the three-dimensional dynamics of knee valgus. This suggests that while 2D measurements can be useful clinically, they may not adequately reflect the complex movement patterns involved in knee injuries.
