Female footballers are up to six times more likely to suffer an ACL injury than their male counterparts, and Inside the WSL sat down with players, physios and doctors to try and find out why.

Unfortunately, it’s not an uncommon sight to see a women’s club announce a player will be sidelined with a ruptured ACL. Just 12 minutes into Arsenal’s WSL match against Manchester United on Wednesday, England captain Leah Williamson ruptured hers, and will miss this summer’s World Cup.

She follows club and country team-mate Beth Mead into the treatment room, after she ruptured her ACL in November, which also puts her World Cup participation in doubt. Arsenal forward Vivianne Miedema picked up the same injury a week after Mead, and has missed much of the season as she goes through the rehab process.

The issue also came to the fore during the summer’s European Championships. Ballon d’Or winner Alexia Putellas missed the tournament after rupturing her ACL just days before Spain’s opening game. Simone Magill also picked up the same injury in Northern Ireland’s opening game of the tournament against Norway, just days after signing for Aston Villa.

France striker Marie-Antoinette Katoto also limped off in their second group game against Belgium, having also ruptured her ACL. She had been one of the favourites to win the Euro 2022 Golden Boot.

You could keep reeling off the names of female players who have gone through the long process of ACL rehabilitation, but as yet, very little scientific research has been done into why women are more likely to suffer from the injury than men.

There are theories such as menstrual cycles playing a key role, although as yet, there hasn’t been enough research to support it.

Mead: More research needed into ACL injuries in women's game

Speaking last month, Arsenal and England star Beth Mead said she hoped there would be more research into ACL injuries in the women’s game.

“It’s important it’s looked into and researched more for ACLs,” she told FIFPRO. “Obviously my rehab so far is going really well. But yes, we’re sitting down, reflecting and having time to have to actually sit down and chill a little bit.

“I think it is important for myself, and Viv [Miedema] also, who’s going through the exact same thing as me right now.

“I think it’s important that we as a collective try and get more done for ACLs and research into it. I think it is way too common in the women’s game. If that ever happened in the men’s game, a lot more would have been done sooner.”

“It’s important for us to drive the different factors and aspects around why it’s happening so often and it will be something that we’ll be delving into and pushing out there to try and get to the bottom of it.”

Speaking to Inside the WSL earlier this season, female health specialist Dr Emma Ross explained: “We know female athletes are up to six times more likely to have a non-contact ACL injury than their male counterparts.

“We published a paper about a year ago which showed that, in sport and exercise science research, only about six per cent of the studies are done exclusively on females – meaning they study things that are happening to the female body – so we don’t have a lot of research on female athletes.

“But what we do know about the menstrual cycle and injury is that the changing hormones across the cycle can impact the physiology and biomechanics of the body.

“For example, when oestrogen is elevated in the menstrual cycle, and that happens in about the second week, it can affect the stability of joints. It can interfere with the collagen in our joints and it can create looser, more lax joints. A loose joint is therefore less stable and more inclined to injury.

“So we do have some information about loose joints, but what we don’t have is the end step of whether that really does increase the risk for injury in female athletes.”

Report author Dr Katrine Okholm Kryger points out women’s feet differ from men’s in shape and volume, and said there’s a risk of injury from ill-fitting boots which can squeeze the foot in unwanted places.

The senior lecturer in sports rehabilitation at St Mary’s University in London told Sky News that “we know that women have a two to five times higher risk of anterior cruciate ligament (ACL) injuries”, which affect the knee.

Other risks include foot deformation, skin conditions like blisters, and even stress fractures.

Many of the major manufacturers are developing women’s specific boots which should be available for the FIFA Women’s World Cup in 2023, but Dr Okholm Kryger said the lack of available football boots is a general concern.

She said she hopes to start a discussion and “kindly nudge manufacturers and research towards to the need to pay more attention is this area”.

One WSL player who has had two ACL injures in recent years is Manchester United defender Aoife Mannion. Shortly after joining Manchester City, she suffered a serious ACL injury in October 2019. Coupled with Covid postponements, Mannion spent 458 days away from pitch and made just 11 appearances for City.

She left the club at the end of her contract, moving to the other side of Manchester last summer. But after a good start under Marc Skinner, ruptured her ACL again in March 2022. She has recently returned to action.

“The first time I did it, it was a clear out-of-body experience,” she told Inside the WSL. “I knew that something had happened, I’d be saved of some of the pain that some people have but I certainly heard it go.

“I’ve had one where it was a very simple ACL and previous one was a very complex one. In terms of contributing factors, we’ve spoken about menstrual cycles maybe. It’s hard as a footballer to start to think in that way in terms of ‘is my body at certain times of the month making me more likely to have an ACL injury’.

“Everything I do is to give me the best chance of not doing it again and getting back to full fitness. I’m aware of the research, I love looking at things and hearing people’s experiences, people who are passionate about ACL rehabs and stuff like that.

“I guess I’m a bit of a geek in that category. At the moment, I’m rehabbing an ACL so I like to hear the research.”

Mannion has been open about both of her ACL injuries and the rehabilitation process, often posting on social media to give updates on her progress.

When asked why, she explained: “The motivation is slightly selfish because I know when I share, kind-hearted people will encourage me and why wouldn’t you want that.

“I would encourage everyone to do a bit of that, to share what they’re doing because people who are on the same wavelength and get it will send encouragement and you have to take all the encouragement you can get.

“I think one of the reasons people don’t share their rehab is they think that either it’s tempting fate of being reinjured or there will have a setback and they’ll look silly. It’s my view that if you’re going to get injured, you’re going to get injured, so why not share the good bits along the way.”

This all leads to the big question – what can be done to help prevent so many female footballers from suffering with ACL injuries?

Dr Ross gave her view, saying: “We need to start measuring the hormones because they are changing across a month and we think that might be impact on things like joint stability and injury risk.

“That comes at a cost and it’s quite an involved way of researching because you have to follow athletes and get them to track hormones, track their symptoms and track their cycle.

“You also have to wait for them to be injured. The one big challenge about injury research is that it’s mostly done retrospectively because we don’t know who’s going to get injured when and why.

“There are a lot of myths out there about the menstrual cycle and injury. In fact, when we go and talk to athletes and footballers, they often say they’re nervous if they get their period and have a game because they think they might be injured, particularly if they’ve been injured before.

“This is an anxiety that they will take into their performance and unfortunately, we don’t have strong enough evidence to say ‘yes, there is a definite time of your cycle when you are more likely to be injured’, but we have lots of headlines which suggest it. Players will read that and start to get worried.

“At the moment, the best we can do is get players to track their cycles and if they are someone who does feel like their hamstring is tighter or their back niggle flares up at a certain time of their cycles, they are better informed to work with their physios and coach to do something about that.

“When people find approaches that have really been useful for them as a female athlete working with their female body, sharing that with other female athletes who may not have access to that information is super helpful.

“We have to consider that everyone is unique and the same approach may not work the same for someone else, but sharing best practise and successful rehabilitation is really important so that we can improve everyone’s understanding of what could work when it comes to injury and injury resilience in footballers.”
