3 Dimensional vs 2 Dimensional Comparison of Knee Valgus Collapse During Vertical Jump Clinical Implications for ACL Risk of Injury Assessment

Introduction

Efficient screening of lower extremity biomechanics is crucial in athletic medicine to prevent anterior cruciate ligament (ACL) injuries. Traditionally, 3D motion capture systems are considered the gold standard for assessing dynamic knee valgus, but they require expensive equipment and time. This study explores the use of 2D kinematic evaluation during a standardized vertical jump assessment to identify injury risks more efficiently.

Key Findings

• 50 collegiate athletes participated in the study, performing vertical jumps as a part of regular performance evaluations.
• The 2D kinematic evaluation demonstrated a strong correlation (P<0.0001) with 3D motion capture, validating its reliability.
• 2D screening was effective in identifying knee valgus and varus patterns, which contribute to ACL injury risk.
• The vertical jump test, commonly used across sports, offers a practical method for integrating injury screening without additional athlete burden.

Clinical Implications and Medical Perspective

The American College of Sports Medicine (ACSM) emphasizes the importance of early injury detection in athletic training. Integrating 2D assessments can enhance the effectiveness of routine screening processes, ensuring proactive injury prevention strategies.
