Reliability and validity of knee valgus angle calculation at single-leg drop landing by posture estimation using machine learning.

ABSTRACT:

Background

The consensus on anterior cruciate ligament (ACL) injury prevention involves the suppression of dynamic knee valgus (DKV). The gold standard for evaluating the DKV includes three-dimensional motion analysis systems; however, these are expensive and cannot be used to evaluate all athletes. Markerless motion-capture systems and joint angle calculations using posture estimation have been reported. However, there have been no reports on the reliability and validity of DKV calculations using posture estimation.

Research question

This study aimed to clarify the reliability and validity of DKV calculation using posture estimation.

Methods

Fifteen participants performed 10 single-leg jump landings from a height of 20 cm, and the knee joint angle was calculated usin
