The prevalence of knee injuries in women's soccer has been caused by a lack of research and investment, former Australia forward Sarah Walsh said ahead of the Women's World Cup.
Several players will miss the Women's World Cup, which kicks off on Thursday, after tearing their anterior cruciate ligaments . Other key players missing with ACL injuries include Janine Beckie , Delphine Cascarino and Marie-Antoinette Katoto , Vivianne Miedema and Catarina Macario and Mallory Swanson .
Theories as to why women are more likely to suffer from ACL injuries range from women playing in boots designed for men to anatomical differences in female players and changing hormones during women's menstrual cycles.
