Sport injuries of knee in relation to malalignment in top athletes

Skeletal system of Athletes could be deformed due to specific demands and tensive performances of them. Also it seems personal factors could be affected to postural malalignment. The aim of this investigation is the study of relationship between knee alignment and sport injuries, age, weight and years of history playing in four groups of sports. The subjects in this study included 100 men with mean age 20.66 ± 4.37 years and mean years of tournament playing of 3.81 ± 2.77 years. Data were collected through questionnaire and examination. Measuring of genuvarum and genuvalgum were done by using modified industrial caliper (accuracy: 1.10mm) and measuring Q angle by standard drawing method and universal goniometer in standard positions. Collected data were analyzed by Pierson correlation coefficient, ANOVA and post hock scheffe test in the P < 0.05. The result indicated the significant difference between Athletic groups with regard to genuvarum, genuvalgum and Q angle (P? 0.05). Furthermore results indicated a significant relationship between knee alignment and sport injuries, also results indicated no significant relationship between age, weight and history playing and knee alignment (P < 0.05).The findings of study emphasis on screening of knee malalignment for preventing of injuries in athletes.
