Patellofemoral disorders, including pain, instability, and arthritis, appear more common in women. This review examines potential sex differences in these conditions, differentiating between sex-based biology and gender-based environmental influences.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Biomedical Science

Background:

  • Sex is biologically determined by chromosomal complement, while gender relates to social roles and presentation.
  • Clinicians observe patellofemoral disorders are more prevalent in females, but supporting literature is limited.
  • Patellofemoral disorders are categorized into pain, instability, and arthritis for analysis.

Purpose of the Study:

  • To review and analyze potential sex differences in patellofemoral disorders.
  • To differentiate between biological sex influences and gender-based environmental factors in these conditions.

Main Methods:

  • Literature review of patellofemoral disorders.
  • Categorization of disorders into pain, instability, and arthritis.

  • Examination of existing evidence regarding sex-based prevalence.

    • Main Results:

    • Anecdotal evidence suggests higher incidence of patellofemoral disorders in women.
    • Literature supporting this sex difference is currently sparse.
    • Further research is needed to clarify the extent and causes of sex disparities.

    Conclusions:

    • Sex differences in patellofemoral pain, instability, and arthritis warrant further investigation.
    • Distinguishing between sex and gender is crucial for understanding these differences.
    • Clarifying these distinctions can inform clinical practice and targeted interventions.
