    INTRODUCTION: The knee is a widely studied joint due to its high incidence of injuries. Most studies correlate these lesions with the valgus during flexion of the knee (dynamic), which is attributed mainly to the poor performance of the gluteus medius muscle. OBJECTIVE: This study had the aim to evaluate the association between the hip medial rotation and the valgus angle (in two dimensions) during the stair descent test obtained through photogrammetry (SAPO software). METHODS: 104 female volunteer athletes were evaluated in the measurement of the hip internal rotation (Craig's test) and the angle value of knee valgus during the descending of a step; the analyses were submitted to inter-rater reliability assessment observed with the Bland and Altman plot. The data were analyzed through multiple linear regression in order to adjust the results to the age of the evaluees. RESULTS: The angle generated in the medial rotation of the hip presented average of 45.3 degrees, with the increase of the knee valgus, while the valgus during the descent movement presented average of 8.6 degrees. Significant inverse relation in the association of the medial rotation and knee valgus was found. CONCLUSION: The presented data show a possible association between the reduction of the medial rotation of the hip with the increase of the knee valgus; however, the data are not conclusive since the evaluation was bidimensional. The obtained results suggest the need of more conclusive studies.
