The Effect of Hallux Valgus Angle on Dynamic Knee Movement Pattern

Abstract Background/aim: Little is known about the relationship between hallux valgus and the alignment of proximal joints. Dynamic knee valgus is a movement pattern characterized by excessive knee abduction along with femoral adduction, internal rotation, and relative external tibial rotation. It is more prevalent in females and exacerbates during landing in jumping, predisposing athletes to injuries. The aim of this study is to investigate the effect of hallux valgus deformity on dynamic knee movement pattern and lower extremity injuries in athletes.

Materials and methods: This is a cross-sectional observational study. The study included 92 athletes with at least 3 years of experience in their respective sports.

About this study

Athletes without acute injuries that could affect performance tests were included. Demographic data were collected, and the hallux valgus angle was measured using a goniometer. A standard warm-up protocol was then administered. A drop jump test from a 30cm platform was conducted, and images captured during the test were analyzed in 2D using Kistler+Noraxon Measurement Device cameras.

Primary outcomes

Drop Jump Test

Time frame: 30 minutes

The drop jump test from a 30cm platform was conducted, and images captured during the test were analyzed in 2D using Kistler+Noraxon Measurement Device cameras. Two cameras were used, one placed in the coronal plane to view the participant from the front, and the other placed in the sagittal plane to view from the left side. Reflective markers were attached to the reference points for measurements

Secondary outcomes

Hallux Valgus Angle Measurement

Time frame: 10 minutes

Hallux valgus angle involves measuring the angle between the long axis of the first metatarsal bone and the longitudinal axis of the first phalanx [15]. The normal value ranges from 8˚ to 10˚. However, some authors suggest lateral deviation up to 15˚ may be considered normal
