Abstract

The aim of this study was to investigate the effect of hallux valgus deformity on dynamic knee movement pattern and lower extremity injuries in athletes. This was a cross-sectional observational study. The study was included 92 athletes (male: 62, female: 30). 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 applied. A drop jump test from a 30 cm platform was conducted, and images captured during the test were analyzed in 2D using Kistler+Noraxon Measurement Device cameras to determine the dynamic knee movement pattern based on the knee-foot ratio. The dynamic knee movement pattern was determined that values greater than 1 were determined dynamic knee varus and values less than 1 were considered dynamic knee valgus. Dynamic knee movement pattern did not show a significant relationship with hallux valgus angle (p>0.05). However, a greater hallux valgus angle was observed in female athletes with a history of injury (p<0.05). This finding was considered an additional observation complementing the primary objective of the study. Sport-based analysis revealed a significantly higher incidence of dynamic knee varus in female weightlifters and dynamic knee valgus in female judoka in our study. The present findings indicate that hallux valgus deformity does not directly alter dynamic knee mechanics. Nevertheless, variations observed among female athletes with prior injuries may reflect secondary biomechanical adaptations rather than a primary effect of the deformity itself.
