Comparison of Return-to-Sports Rates Between Male and Female Australian Athletes After ACL Reconstruction

BACKGROUND: Return to sports (RTS) is a goal for most patients who undergo anterior cruciate ligament reconstruction (ACLR). Although it has been reported that women RTS at a significantly lower rate compared with men, demographic and contextual factors that may be associated with this have not been investigated. PURPOSE: To compare RTS rates between men and women and investigate factors that may be associated with different rates of RTS in an Australian context. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A total of 1338 patients who underwent primary ACLR between January 2014 and December 2017 were invited to complete a detailed sports participation questionnaire 2 to 7 years after surgery. RTS rates were calculated and compared between men and women overall and after stratifying by age at surgery (<20, 20-29, 30-39, or ≥40 years) and geographical location (metropolitan or rural). Contingency analysis was performed to compare factors associated with rates of RTS. RESULTS: The survey completion rate was 81% (1080/1338). Overall, women had a significantly lower RTS rate compared with men (65.4% vs 74.9%; P = .001). However, when patients were grouped by age, the lower rate of RTS for women was significant only in the 20- to 29-year age group (P = .01). For athletes who returned to sports, there was no sex-based difference when comparing the levels of RTS. When grouping patients based on geographical location, there was a significantly lower rate of RTS in metropolitan-based women compared with metropolitan-based men (P < .001) and rural-based women (P = .042). CONCLUSION: Although women returned to sports at a lower rate than men overall, this difference was predominantly seen in the 20- to 29-year age bracket and in those who lived in metropolitan areas. There was no difference between men and women regarding the RTS level.
