Morphometric Findings in Medial Patellofemoral Ligament Rupture Compared to Individually-Matched Controls

Abstract

BACKGROUND The purpose of the present study was to evaluate patellar height and trochlear groove angle in individuals with and without medial patellofemoral ligament rupture for surgical reconstruction and possible clinical use. METHODS The study had a retrospective design, and included 149 people (53 females, 96 men) who were between the ages of 18 and 36 admitted to the Orthopedic Clinic of Bartın State Hospital with various complaints in knee joints and different preliminary diagnoses between January 2005 and December 2020. The study population was examined as two groups, those with and without medial patellofemoral rupture. The study included 61 patients with medial patellofemoral ligament rupture and 88 patients without medial patellofemoral ligament rupture. Patellar morphology, patellar height, trochlear morphology, and patellar alignment were measured from digital MRI images. RESULTS As a result of the study, while significant differences were detected in trochlear groove angle, there wasn’t significant differences in patella elevation (patellar height) between the groups (with and without medial patellofemoral ligament rupture). CONCLUSIONS Our study has versatile evaluation parameters, it will make a significant contribution to the literature.
