Evaluation of patellar tendon morphology in Turkish population: a cross-sectional study

Aim: This study aims to investigate the length, width and thickness of the patellar tendon and the type and length of the patella with MRI and to reveal the normal values of patellar tendon morphology specific to the Turkish population. Material and Method: The study was conducted with 348 individuals (137 males, 211 females) who applied to our hospital, had no anterior knee pathology, and had knee MRIs. The length, proximal and distal width and thickness of the patellar tendon, patella type, prepatellar and infrapatellar fat pad signal characteristics and Insall-Salvati ratio were evaluated on knee MRI images of these individuals. Results: Type I patella was detected in 23.9%, type II in 57.2%, type III in 16.1%, and type IV in 2.9% of individuals. The mean length of the patella was 41.26±4.36 mm, the patellar tendon length was 47.36±6.70 mm, the proximal width was 28.86±3.49 mm, the distal width was 23.53±2.69 mm, the proximal thickness was 3,62±1.47 mm, and distal thickness was 5.21±1.1 mm. It was determined that the Insall-Salvati ratio did not cause a statistical difference according to age, but the patella type showed significance with the Insall-Salvati classification. Conclusion: While evaluating MRI images, the effect of social differences on measurements should not be ignored; normal measurement values of the tendon should be known to evaluate pathological measurements.
