Osteoarthritis

Sex differences in patellar facet shape among healthy and osteoarthritic cohorts

Osteoarthritis CartilagePublished Cross-sectional study

Authors' conclusion

Medial and lateral facet shapes showed different patterning of variation by sex and healthy/OA status.

Study context

Population
Healthy and patellofemoral osteoarthritis (OA) knees (OA individuals on a waitlist for total knee replacement)knees scanned via CT
Participants
97 vs 67
Exposure
Females vs males, in healthy and patellofemoral OA knees
  • Healthyn = 97reference
  • OAn = 67
Outcome
Sex and healthy/OA differences in patellar morphology (2D measurements and 3D medial and lateral facet shape)
Methodological detailsCT-based 3D patellar morphology, Procrustes analysis of variance (ANOVA), Principal Component Analysis
  • CT-based 3D patellar morphology
  • Procrustes ANOVA
  • Principal Component Analysis

Main finding

As reported in the abstract

  • Differences in patellar 2D measurements between healthy and OA individuals were smaller than differences between males and females
  • Sex and healthy/OA differences most pronounced for medial facet shape: posteriorly-curving, taller, narrower facet in males vs females
  • Lateral facet shape variance higher in OA cohorts vs healthy groups

Observational data: associations, not effects.
