What we all know to this point
It has lengthy been recognized that females are round thrice extra more likely to undergo ACL damage in contrast with males. One research estimates {that a} feminine athlete has a one in twenty probability of an ACL damage yearly, nevertheless it’s nonetheless not clear precisely why.

In soccer, defending is a specific threat because it includes unanticipated or reactive positions. And elevated coaching and sport time amongst skilled ladies footballers over current years has resulted in additional publicity to those high-risk conditions.
It has additionally been urged that fatigue might enhance the danger of ACL damage – with drained muscular tissues much less in a position to soak up shock and management actions. But whereas this hyperlink appears logical, ACL accidents don’t happen extra ceaselessly later in a sport or the season, which you’d anticipate if it was all the way down to fatigued muscular tissues. So might or not it’s all the way down to variations in anatomy between women and men?
Anatomical variations
Females have a wider pelvis relative to leg size, which ends up in elevated angulation on the knee. The form of the bones can be totally different in ladies in that the ACL passes by way of a narrower house to connect to the thigh bone, which can make it extra vulnerable to damage. The precise dimension of the ACL can be typically smaller in females, so could also be much less in a position to face up to excessive forces.
In common, females have looser knee ligaments, which has been proven to extend the danger of damage. It’s thought that having looser knee ligaments can diminish joint proprioception – this can be a sense of motion and place which is crucial to carry out motion duties safely.
It has additionally been urged that ladies could also be extra vulnerable to ACL damage at sure instances of their menstrual cycle. This is as a result of altering hormones, particularly when oestrogen ranges are at their highest (round day 12 in a 28-day cycle), can enhance the looseness of joints (hypermobility).
While some analysis exhibits that oral contraceptives could assist to scale back this threat, newer proof means that the tablet has no protecting impact.
Studies additionally present that ladies have delays within the activation of hamstrings are likely to overuse their quadriceps when touchdown from a leap, which will increase the power on the ACL.
Reduced energy within the trunk (core) muscular tissues and the hip have additionally been proven to foretell knee damage in females. Research has additionally discovered that ladies are likely to land on a knee that twists or buckles inwards, which is often seen in ACL accidents.
What could be accomplished?
There’s little question that the elevated price of ACL damage in females isn’t all the way down to anyone factor. Indeed, analysis from 2021 additionally exhibits that social and gender roles in sport could enhance the danger of ACL damage in females – with ladies’s soccer (at each skilled and grassroots degree) nonetheless receiving much less funding and experience in contrast with the boys’s sport.
Though there’s good proof that enhancements could be made by way of particular coaching programmes. It has even been urged that every one feminine athletes, particularly these underneath 18, ought to use these programmes to assist scale back the danger of significant damage.
One research, for instance, discovered that by doing a collection of particular workouts, feminine athletes might scale back their threat of ACL damage by 50% – with a 67% discount for non-contact ACL accidents.
Although the analysis signifies that such interventions could also be more practical in youthful gamers than skilled athletes, these programmes do appear to work and are simple to implement, making them cost-effective with little threat.
At the second, prevention programmes are essentially the most highly effective device we now have to scale back damage. So they need to be promoted broadly and carried out at an early age in all high-risk sports activities to assist stem the catastrophic epidemic of feminine ACL accidents.
