Why this matters

For years, the disproportionate rate of ACL tears in women's soccer was dismissed as a biological inevitability, sidelining generational talents and cutting careers short. The successful return of players like Galli, combined with the new 'Project ACL' initiative, signals a long-overdue shift toward systemic changes in scheduling, travel, and sports science that will protect the long-term health of female athletes.

Key points

  • Everton's Aurora Galli has returned to the pitch after a grueling 20-month ACL rehabilitation.
  • Female soccer players are two to six times more likely to suffer ACL tears than male players.
  • The NWSL and WSL have launched 'Project ACL' to study the environmental causes of the injury epidemic.
  • The three-year study tracks player workloads, travel burdens, and 'critical zone' match appearances.
  • Only 8 percent of global sports science research currently focuses exclusively on female athletes.
  • Leagues are proactively introducing off-field treatment rules and mandated recovery breaks to protect players.

For Everton midfielder Aurora Galli, the nightmare began 83 minutes into the opening match of the 2024-25 Women's Super League season. Attempting to salvage a loose ball against Brighton, her standing leg buckled beneath her. The Italian international immediately signaled for medical staff, her agonizing screams echoing through Broadfield Stadium. The diagnosis confirmed her worst fears: a ruptured anterior cruciate ligament (ACL), an injury that would steal nearly two years of her prime.[1][2]

The rehabilitation process was a grueling test of endurance. Galli spent 20 months confined to the gym at Everton's Finch Farm training base, battling the profound psychological isolation that accompanies long-term injuries. She later admitted that the mental toll of accepting she could no longer play the sport that defined her life was just as painful as the physical recovery. The night before the injury, she had even dreamt about her ACL tearing—a haunting premonition of the arduous road ahead.[1]

But in May 2026, the darkness finally lifted. On the final day of the WSL season, Galli made a triumphant four-minute cameo against Tottenham. Though brief, stepping back onto the pitch was a monumental victory that fully cleared her for the summer international window. Reintegrated into the Italy national team setup, Galli's return is a testament to individual resilience, but it also casts a spotlight on a systemic crisis that women's soccer is finally attempting to solve.[1]

Galli's story is far from unique. The women's game has been ravaged by an epidemic of knee injuries, claiming high-profile victims like Chelsea's Sam Kerr, Arsenal's Leah Williamson, and the USWNT's Catarina Macario. Statistically, female soccer players are between two and six times more likely to suffer an ACL tear than their male counterparts. For decades, the sports medicine establishment shrugged this off as a biological misfortune, pointing to wider hips and hormonal fluctuations as unavoidable culprits.[5]

Female soccer players face a significantly higher risk of ACL injuries, a disparity researchers are now working to solve.

That narrative is finally being dismantled. Researchers and players' unions are increasingly pointing to environmental factors—often rooted in systemic inequality—as the true drivers of the crisis. Poor pitch standards, congested fixture schedules, a lack of access to elite weight-training facilities, and soccer boots designed exclusively for male feet have all been identified as critical risk factors. As advocates in the space have bluntly summarized: sexism, not just biology, is the risk factor.[4][5]

Researchers and players' unions are increasingly pointing to environmental factors—often rooted in systemic inequality—as the true drivers of the crisis.

To address this, the global soccer community has launched "Project ACL," a pioneering three-year research initiative. Originally spearheaded by the WSL, FIFPRO, Nike, and Leeds Beckett University, the project expanded across the Atlantic in April 2026 when the National Women's Soccer League (NWSL) and its players' association officially signed on. The partnership marks the first time two of the world's top professional leagues have coordinated a cross-league study to combat the injury epidemic.[3][4][6]

The data collection phase for the NWSL began in June 2026, adding 16 clubs and an entirely new set of environmental variables to the research pool. Unlike the geographically compact WSL, the NWSL requires grueling cross-country travel across multiple time zones. By comparing the two systems, researchers hope to isolate exactly how different travel burdens, training cultures, and commercial pressures impact joint health.[6]

The physical demands of modern women's soccer have outpaced the development of female-specific sports science and scheduling protections.

A major focus of Project ACL is tracking "critical zone" appearances—matches played with fewer than five days of recovery time. Using FIFPRO's Player Workload Monitoring tool, the study is building an evidence-based link between scheduling demands, chronic fatigue, and catastrophic ligament failures. The goal is to force competition organizers to treat adequate rest as a non-negotiable piece of league infrastructure rather than an afterthought.[4]

The initiative is also working to correct a glaring blind spot in sports medicine. Currently, a staggering 92 percent of global sports science research focuses on male or mixed-gender cohorts, leaving just 8 percent dedicated exclusively to female athletes. Project ACL is conducting extensive interviews with players to build a massive, female-centric database that will inform everything from bespoke cleat manufacturing to menstrual-cycle-aware training regimens.[4][5]

A staggering lack of female-centric sports science data has hindered injury prevention efforts in women's soccer.

Leagues are not waiting for the final study results to implement protective measures. The NWSL recently introduced an Off-Field Treatment Rule to improve match flow while ensuring injured players receive immediate, unpressured medical attention. Furthermore, the league's new CBA-mandated summer break is providing a crucial recovery window, allowing players managing minor knocks to rehabilitate without the pressure of missing competitive fixtures.[4][5]

For players like Aurora Galli, the systemic changes come too late to prevent the initial trauma, but they offer hope for the remainder of her career. As she builds her match fitness ahead of the 2026-27 WSL campaign, she does so in an ecosystem that is finally taking her physical safety seriously. The era of accepting catastrophic knee injuries as the cost of doing business in women's soccer is coming to an end.[1][3]

Ultimately, the expansion of Project ACL represents a maturation of the women's game. By treating player welfare as a foundational pillar rather than a luxury, global leagues are protecting their most valuable assets. Triumphant returns like Galli's will always be celebrated for their grit, but the true victory will be a future where such grueling comebacks are the rare exception, not the rule.[3][6]

Viewpoints in depth

Recovering Athletes

Focuses on the immense psychological and physical toll of long-term rehabilitation.

For players who suffer catastrophic knee injuries, the physical pain of surgery is often eclipsed by the psychological isolation of rehabilitation. Athletes like Aurora Galli describe the 9-to-20 month recovery process as a test of mental endurance, where the sudden loss of their primary identity—playing soccer—can lead to profound struggles. The triumph of returning to the pitch is celebrated not just as a physical milestone, but as the culmination of a grueling mental battle to reclaim their careers.

Sports Scientists & FIFPRO

Argues that the ACL crisis is an environmental issue rather than a biological inevitability.

Sports scientists and union advocates are aggressively pushing back against the historical narrative that female athletes are simply biologically predisposed to ACL tears due to wider hips or hormonal cycles. Instead, they point to systemic inequalities in the sport's infrastructure. They argue that playing on substandard pitches, wearing boots designed for male feet, and competing in congested schedules without elite recovery resources are the true culprits behind the epidemic. By shifting the focus to these environmental factors, researchers believe the injury rate can be drastically reduced.

League Administrators

Focused on implementing data-driven scheduling and rule changes to protect player health.

For league executives in the NWSL and WSL, the ACL epidemic represents both a moral failing and a massive financial liability. Losing marquee players to preventable injuries damages the on-field product and hurts commercial growth. In response, administrators are increasingly relying on data-driven workload monitoring to optimize schedules. By participating in cross-league studies like Project ACL and implementing mandated rest periods, leagues are attempting to build a sustainable infrastructure that protects their most valuable assets from burnout and catastrophic injury.

What we don't know

  • Whether the findings from Project ACL will lead to mandatory changes in global FIFA scheduling calendars.
  • How quickly major sportswear brands will universally adopt female-specific boot designs based on the study's data.
  • If the NWSL's cross-country travel burden will prove to be a significantly higher risk factor than the WSL's localized travel.
