Background: The quadriceps angle (Q-angle) affect the biomechanics of the lower extremities and is important in assessing the knee joint function. Increasing Q-angle can increase the risk of knee injury and also the chance of an athlete withdrawing from training or competition. Ligament laxity, gender, and high body mass index are proposed as risk factors for increasing Q-angle. Only a few research have investigated the correlation between these risk factors and Q-angle in competitive athletes, especially in Indonesia. This study aims to determine the correlation between Beighton score, genders, body mass index and Q-angle in competitive athletes in Indonesia.
Method: This study was a non-reactive study that used medical records from 94 competitive athletes collected to determine the subjects’ characteristics and research variables. The sampling technique was proportional random sampling. Ordinal regression tests were performed to assess the correlation between Q-angle and Beighton Score, Genders, and Body Mass Index in competitive athletes.
Result: There is a significant correlation between Beighton score and Q-angle in the supine position (p=0.000, R=2.829) and standing position (p=0.000, R=2.839), as well as body mass index and Q-angle in the supine position (p=0.003, R=0.23) and standing position (p=0.002, R=0.259), but there is no significant correlation between genders and Q-angle in the supine position (p=0.262, R=0.517) and standing position (p=0.235, R=0.550).
Conclusion: In competitive athletes, there is a strong correlation between Beighton score and Q-angle in both positions, as well as body mass index in both positions; nevertheless, there is no correlation between genders and Q-angle.
