Relationship Between Q Angle and Knee Injuries Prevalence in Elite Volleyball Players

Abstract

Recent study was performed to determine relationship between Q angle and knee injury prevalence in 70 elite volleyball players (35 male and 35 female, age of 26.43 ± 3.56 years old and volleyball background of 7.32 ± 1.23 years) with no musculoskeletal pathology that influence the Q angle. Participants fulfilled contest form and injury prevalence was collected by standard Australian injury questionnaire. The Q-angle was measured using a universal Goniometer with the subject in the erect weight-bearing position. Injury prevalence was reported 12.52%, 11.89%, 11.53% and 11.25% in right and left knee in male and female respectively. Mean average and standard deviation of Q angle was 12.34 ± 2.36° for right and 12.48 ± 2.62° for left leg. Results of pair t-test showed no significant differences between right and left Q angle in male and female but independent t test showed significant differences between right legs in male and female as well as left. Significant relationship was determined between Q angle and injury prevalence using chi-square tests.
