Magnetic Resonance Imaging Study of Age and Sex Variation in the Anatomy of Patellofemoral Articulation
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 9
Abstract
Background: The knee joint is one of the strongest and most complex joints in the human body. The knee is a tricompartmental joint. It is formed by union of the patellofemoral joint (PFJ) and the medial and lateral tibiofemoral joints. PFJ is a complex structure comprising the extensor mechanism of the knee and the femoral trochlea. Females are more prone to recurring dislocations of the PFJ. They are afflicted by isolated PF twice as frequently as males. The anatomical background for this prevalence needs to be studied. Aim of Study: The aim of the study was to study the age and gender variations in various morphometric parameters of the PFJ to the highest possible accuracy using magnetic resonance imaging (MRI) in South Indian Population aged 20–70 years; to provide a baseline data of PFJ morphometric parameters in South India. Materials and Methods: The parameters studied in the study were knee joint MRI obtained from the records of Department of Radiology with the following settings: (1) All studies were performed with a Signa 1.5 T MRI System (GE, Milwaukee, WI, USA). (2) At the time of imaging, every patient was made to lay supine with the knee joint straightened and neutrally rotated. (3) T2-weighted sagittal and axial images of knee joint were studied. (4) The slice thickness for all the sequences was 4 mm. The PF anatomy and congruence were assessed using a total of 22 parameters. Observations and Results: Out of the 140 knee MRI records, 70 (50%) were males, and 70 (50%) were females. Among the 70 males MRI records, 31 (44.3%) were of the right knee and 39 (55.7%) of the left knee. Of the 70 female Knee MRI, 39 (55.7%) were of the right and 31 (44.3%) of the left knee. The mean value reveals statistically significant difference (P ≤ 0.05, Student’s unpaired t-test) across gender for 18 out of the 22 parameters denoting sex variation in the PFJ among the South Indian population. Conclusions: From our present MRI study in 70 males and 70 females representing the South Indian population, it was concluded that 18 out of the 22 morphometric parameters of the PFJ depicted significant gender variation (P ≤ 0.05, Student’s unpaired t-test). 16 parameters were found to be statistically highly significant with a P value below 0.001.
