Why Female Athletes Are at Greater Risk for ACL Injuries: Insights from a Melbourne Sports Chiropractor
As a leading sports chiropractor in Melbourne, at Shannon Clinic we see firsthand the impact of ACL injuries on athletes’ careers and lives. Anterior Cruciate Ligament (ACL) tears are a common nightmare for female athletes, often sidelining them from the sports they love like soccer, AFL, and basketball. Did you know that women are up to three times more likely to suffer these injuries than their male counterparts in similar sports?
This alarming disparity isn’t just a statistic—it’s a call to action for better prevention and care. In this post, we’ll dive into the data from high-quality systematic reviews and meta-analyses, explore the key risk factors, and discuss emerging research on protective strategies. Whether you’re a female athlete in Melbourne’s CBD seeking a chiropractor for injury prevention or a coach looking to safeguard your team, understanding these insights can make all the difference
How Much Higher Is the ACL Injury Risk for Female Athletes?
Let’s start with the numbers. A high‑quality systematic review and meta‑analysis showed a clear pattern: female athletes experience ACL injuries 1.5–2.7 times more often than males in the same sports.. This holds true across contact sports, where women sustain ACL injuries at three times the rate of men, according to a systematic review of injury risks by sex and sport classification. In soccer, for instance, the incidence is notably higher for females, with studies reporting rates up to 0.391 per 1,000 person-days in college players—far surpassing those in high school or male equivalents.
Basketball tells a similar story. The same meta-analysis highlights a threefold increase in ACL tears for women, emphasizing the non-contact nature of many incidents. Even in Australian favorites like AFL, where explosive pivots and tackles are routine, female players face elevated risks, aligning with broader patterns in high-impact sports. Overall, adolescent female athletes have nearly a 1 in 10,000 athlete-exposure risk, about 1.5 times that of males. These figures aren’t just from isolated studies; they’re backed by comprehensive reviews that underscore the need for targeted interventions. As a CBD chiropractor specializing in sports injuries, we’ve helped countless Melbourne athletes recover and prevent such setbacks through personalized alignment and strength programs.

Unpacking the Risk Factors: Why Women Bear the Brunt
The question arises: why are female athletes more prone to ACL injuries? It’s a mix of anatomical, hormonal, and historical factors, all supported by robust research. Let’s break it down.
Anatomical Differences: Tibial Slope and Q Angle
Anatomy plays a pivotal role. Women often have a steeper posterior tibial slope, which increases stress on the ACL during dynamic movements like landing or cutting in soccer or basketball. A systematic review confirms that increased tibial slope is a significant risk factor for ACL injury. Similarly, the Q angle—the angle formed by the quadriceps muscle relative to the patella tendon—is typically larger in females due to wider pelvises, leading to greater knee valgus (inward collapse) and instability.
Studies link this increased Q angle directly to higher ACL rupture rates, with one assessment showing it as a key predisposing factor. As a sports chiropractor in Melbourne, we at Shannon Clinic focus on biomechanical assessments to address these issues, helping athletes optimize their form and reduce strain.
The Hormonal Debate: Menstrual Cycle Influences
Hormones add another layer of complexity. Fluctuations during the menstrual cycle, particularly peaks in relaxin—a hormone that loosens ligaments—may weaken ACL integrity. A systematic review found hormone variations linked to increased injury risk, especially around ovulation. Some evidence points to the mid-luteal phase as a high-risk period for non-contact ACL tears. Relaxin surges have been correlated with higher ACL injury rates in reviews examining menstrual cycle effects. While the debate continues, these findings suggest tracking cycles could be part of prevention strategies. Our chiropractic team in Melbourne’s CBD integrates hormonal awareness into training advice for female clients.
Historical Barriers: Access to High-Performance Programs
Beyond biology, systemic issues contribute. Historically, female athletes have had limited access to high-quality high-performance programs and sports medicine care, leading to inadequate strength training and injury prevention. A review notes that youth female athletes often lack structured conditioning, exacerbating ACL risks. This disparity is evident in underrepresentation in rehabilitation studies and prevention initiatives, with women facing 2-8 times higher injury rates partly due to these gaps. Fortunately, programs like those reducing ACL injuries by up to 67% in females are gaining traction, but access remains uneven. At Shannon Clinic, our chiropractor services in Melbourne bridge this gap with tailored sports medicine approaches.

Could Oral Contraceptives Offer Protection?
Emerging research explores whether oral contraceptives (OCs) could mitigate ACL risks by stabilizing hormone levels. A meta-analysis suggests a protective association, with limited evidence indicating OCs might reduce injury likelihood. One study found women on hormonal birth control had a statistically decreased risk of ACL surgery. Retrospective data shows OC users may be at reduced risk, potentially by dampening relaxin effects and knee laxity. However, results are mixed—a systematic review found no strong protective effect against musculoskeletal injuries overall. Although ACL-specific studies lean positive the evidence is not yet conclusive. Always consult a healthcare professional before considering OCs for this purpose. As a Melbourne chiropractor, we recommend combining such strategies with chiropractic care for holistic protection.
