Morphometric analysis of chondromalacia patella and patella types

Abstract

Aims: The present study was conducted to determine patella types, chondromalacia patella finding in the Turkish society, and to evaluate the differences between gender and age groups to with Magnetic Resonance Imaging (MRI). Methods: The study had a retrospective design, and included 256 people (122 females, 134 male) who were between the ages of 18 and 81 admitting to the Orthopedic Clinic of Kozan State Hospital with various complaints in knee joints and different preliminary diagnoses between January 2015 and December 2017. The evaluations made on MR images in the study. We evaluated in our study were patella types, chondromalacia classification and comparison according to age and gender. Results: Patella types did not differ between the genders at significant levels; however, significant differences were detected between the genders in the chondromalacia patella (p=0.03). Patella types were classified, and it was found that Type II Patella was the most common patella type, and Type IV was identified as the least common. Conclusion: We believe that the data obtained in our study will be useful in understanding morphometry of patella in anatomy, radiology and orthopedics fields. Based on our findings, we concluded that the anatomical shape of the patella is an important anatomic parameter, which may reflect the development of defects in the patellofemoral region It is also clinically important in terms of identifying knee pathologies more clearly in the aging process, and revealing the differences between societies, and in many pathologies that involve patella.
