What Does the Research Say?
Sex Differences in Patellofemoral Pain: Why Women Are at Higher Risk
The gap is real, consistent, and driven by more than anatomy. Understanding why helps you build better prevention and treatment programs.
2×
Women demonstrate nearly double the incidence of patellofemoral pain compared to men, a finding consistent across military, athletic, and primary care populations.
Primary Care Gap
4.6 vs. 2.3
Incidence per 1,000 person-years in females vs. males aged 7 to 24, from a study of over 300,000 patients.
Dynamic Knee Valgus
↑
Women show greater contributions from hip adduction and internal rotation to dynamic valgus during single-leg tasks, increasing lateral patellofemoral contact pressure.
Load Carriage Stress
↑
Even after controlling for body mass, height, and quadriceps strength, women showed significantly greater patellofemoral joint stress increases with added load.
Young Gymnasts
33.3%
Prevalence of patellofemoral pain in artistic gymnasts. Reduced knee extensor and hip abductor strength were key modifiable risk factors.
3 Takeaways for Your Practice
1
Assessment Strategy
Prioritize Hip Strength Testing in Female Patients
Women demonstrate greater hip adduction and internal rotation contributions to dynamic valgus. Targeted assessment of hip abductor and external rotator strength should be standard in female patients presenting with anterior knee pain.
2
Training Modification
Slow the Load Progression for Women in Loaded Activities
Biomechanical research shows women experience greater patellofemoral stress during load carriage even after accounting for body size and strength differences. Hiking, backpacking, and military training programs may need slower progressions for women.

Youth Prevention
Screen Female Adolescents During Growth Spurts
The peak incidence at age 13 for both sexes, combined with girls' elevated vulnerability during puberty, makes targeted neuromuscular screening in young female athletes one of the highest-yield prevention strategies available.
