ABSTRACT
Transvers geniculate ligament does not exist in all people and in some articles it was mentioned as a normal variation. The aim of this study was to assess the prevalence of transverse geniculate ligament in an Iranian's people sample. It was a descriptive-analytic and prospective study. It was conducted on one hundred and fifteen patients with different indication for knee MRI. Transverse ligament prevalence with 95% confidence intervals for its length and width were calculated through SPSS software. Finding showed that prevalence of transverse genicular ligament was 53.9%. There was no statistically relationship between exist of this ligament and sex of patients [P=0.5]. Average length and width of this ligament were 30.158; 95%CI [20.0-42.70] mm and 2.299; 95%CI [0.5-4.20] mm respectively. There wasn't statistically relationship between exist of this ligament and age of participants either [P=0.161]. Although our study sample possessed partly high frequency of transverse ligament prevalence, it still need to be more studies in different people in other races and countries to evaluate true prevalence of this ligament. Also physicians must be informed about this partly high frequency.
