Out of 96 patients included in the study, 48 patients had ACL tear (Group A) and 48 patients did not have an ACL tear (Group B). Demographic data and clinical information were noted for all patients. Descriptive variables were expressed as mean and standard deviation for quantitative variables and frequency and percentages for qualitative variables. The data was analyzed using SPSS® version 21.0.
