Analysis of the relationship between meniscal tears and medial patellofemoral rupture according to the treatment method and gender

Abstract

Objective: The aim of this study was to make a detailed anatomical analysis of the parameters of patellar height, the congruence angle, the lateral patellofemoral angle in patients with medial patellofemoral rupture, according to the treatment method (surgical or conventional), gender and whether or not there is a lateral and medial meniscus tears. Methods: This study was planned as retrospective study between January 2010 and January 2021. Magnetic resonance images (MRI) of 61 knees (61 individuals) were obtained for analysis. Of those, 38 knees were left, and 23 were right. One orthopaedic surgeons and two anatomist independently measured patellar morphology, patellar height and patellar alignment and evaluation lateral and medial meniscus tears. Knee MRI protocol including axial T2-weighted turbo spin echo (TR:3600, TE:87 ms; slice thickness 5 mm; gap 1.5 mm) was used. Results: There was a significant difference patellar height (surgery; 1.21±0.27 and conventional; 0.99±0.16), the congruence angle (surgery; -4.94±4.72 and conventional; 4.93±5.72), the lateral patellofemoral angle (surgery; -35.61±16.62 and conventional; 10.93±15.00), except for age parameter (surgery; 27.06±6.20 and conventional; 27.47±5.33) between the conventional and surgical treatment groups (p
