ACL Injuries in Female Soccer Players
What is the ACL, and how does it impact female soccer players?
Anterior Cruciate Ligament (ACL) injuries are one of the most significant challenges female soccer players face. This injury can impact both their performance and long-term physical health. This blog will analyze the female population, anatomical analysis, treatment that can help prevent injury, and rehabilitation methods. Understanding why soccer players are more likely to have an ACL injury, and more specifically, why female athletes are at higher risk, will be answered by the end of this blog. Understanding why soccer players, especially female athletes, are at higher risk for ACL injuries will be a key focus, with insights from the physical therapists at Austin Manual Therapy Associates. This blog will emphasize the role of expert rehabilitation, injury prevention strategies, and personalized treatment plans provided by our clinic to help all types of athletes, male or female, stay strong and reduce their risk of injury.
What is the ACL?
The Anterior Cruciate Ligament (ACL) is one of four primary ligaments in the knee, along with the Medial Cruciate Ligament (MCL), Lateral Cruciate Ligament (LCL), and Posterior Cruciate Ligament (PCL). These ligaments have crucial roles in attaching the superior (upper) and inferior (lower) parts of the lower extremities. More specifically, the ACL connects the femur to the tibia, which prevents excessive movement of the knee. The knee functions as a hinge joint, which allows for flexion (bending) and extension (straightening) while maintaining appropriate rotation. This biomechanical function is essential for activities such as walking, sitting, and maintaining balance. Injury to the ACL, commonly resulting from abrupt pivoting or direct trauma, can lead to partial or complete ligament rupture. ACL tears are often associated with significant pain, instability, and functional impairment and will often require a long rehabilitation period and, in many cases, surgical intervention to restore joint stability and function.
Why are females more prone to ACL tears?
Females are the most prone to ACL tears due to a combination of anatomical, biomechanical, and hormonal factors. Their anatomical structure is very different from men's, as women have a naturally wider pelvis, which helps during childbirth. This alignment will impact the angles at which the lower extremity will naturally move, as the Q-angle increases (the angle formed between the quadriceps muscle and the patellar tendon). A higher Q-angle places greater stress on the knee joint and can contribute to instability, increasing the likelihood of ACL injuries.
Females tend to have a higher percentage of body fat in the waist and thigh regions, as there is more estrogen in those regions that are vital for reproduction. Their natural body shapes and sizes can place greater stress on the knees, making them more susceptible to difficulties in sustaining both basic and complex movements.
The age of 16 is a particularly common time for females to experience ACL tears, as this stage of puberty brings significant physiological changes, including increased hormone levels, muscle growth, and fluctuations in muscle laxity during the menstrual cycle. When laxity increases, it is hard for the muscles to hold strength and stabilize, which can cause shifting and tearing in the muscles.
Additionally, soccer players experience the highest rate of ACL injuries among all sports. This statistic is largely attributed to the dynamic movements required in the sport, as well as the playing conditions and environment.
Common Causes of ACL Injuries
ACL injuries often result from movements like rotation, inversion, eversion, and torsion. Sudden direction changes, such as pivoting or tackling, put excessive strain on the ligament, especially when the body is unprepared or not strong enough to handle pinpointed weight at the knee. As a vital knee stabilizer, the ACL prevents excessive tibial movement and controls rotation. Abrupt, unsteady motions can overstretch or tear the ligament.
External factors also contribute to ACL injuries, with playing surfaces being a major risk factor. Turf fields create more friction than grass, increasing non-contact injuries. Even grass fields can be hazardous when wet or uneven. Footwear also plays a role, as cleats with longer studs may cause the foot to get stuck during quick directional changes.
Planted feet combined with rapid upper-body rotation generate significant knee torque, increasing the risk of ACL tears. Poor landing mechanics, especially with extended or inward-angled knees, add to the strain. Weak quadriceps, hamstrings, and glutes further reduce stability, making the knee more vulnerable.
Female athletes face a higher risk due to anatomical, hormonal, and biomechanical differences. Hormonal fluctuations can increase ligament laxity, making the ACL more susceptible to injury. Strength training, neuromuscular control exercises, and proper warm-ups help reduce risk. Injury prevention is crucial in high-risk sports like soccer, basketball, and football.
An ACL injury not only weakens the ligament but also impacts surrounding muscles like the quadriceps and hamstrings, which support the hip and ankle. Without proper strengthening, these muscles can weaken, increasing the risk of further injury. Recovery typically requires six to nine months of rest, combined with strength training to maintain lower-body stability. Working with a physical therapist during this time is essential, as they provide targeted exercises that gradually increase in difficulty as strength and mobility improve.
What are the types of ACL injuries?
ACL injuries range from mild sprains and strains to complete ruptures, which often require surgical intervention. Severe cases can also damage nearby bones, muscles, tendons, or ligaments, further complicating recovery. Additionally, conditions like rheumatoid arthritis, which causes joint inflammation and limited mobility, can worsen ACL-related issues.
Long-term complications of ACL injuries may contribute to bone health concerns, including osteoporosis, due to reduced activity and muscle weakening. Proper management involves a comprehensive approach, including medical treatment, rehabilitation, and lifestyle adjustments to restore stability and prevent further damage.
How to Prevent ACL Injuries
Warm Ups and Cool Downs
A comprehensive warm-up is crucial in preventing ACL injuries. Before physical activity, individuals should engage in dynamic stretches and exercises that activate key muscle groups, such as the quadriceps, hamstrings, and calves. Dynamic stretching, such as leg swings, high knees, and lunges, helps improve flexibility, range of motion, and muscle coordination. This prepares the muscles and joints for the demands of intense activity, especially in sports involving rapid direction changes. A proper warm-up ensures the body is ready for explosive movements, reducing the risk of overstretching and tearing the ACL during sudden pivots or stops.
One of the most effective ways to prevent ACL injuries is by learning and applying proper movement techniques. Athletes should focus on knee alignment, posture, and landing mechanics, particularly when jumping or cutting. Training programs that reinforce proper landing techniques with the knees slightly bent and aligned with the toes can reduce stress on the ACL. Additionally, understanding and avoiding valgus collapse, where the knee caves inward during movement or sudden change in direction, puts excessive strain on the ACL. By ingraining proper movement patterns, athletes can reduce the risk of ACL injuries.
Consistent Active Lifestyle
Maintaining strength and stability in the muscles surrounding the knee joint is crucial for injury prevention. Strengthening exercises for the quadriceps, hamstrings, and glutes help create a balanced musculature that can better absorb impact and support the knee during physical activity. Exercises such as squats, lunges, and leg presses can be highly effective in building strength. In addition to muscle strengthening, neuromuscular training, which improves coordination and balance, plays a vital role in controlling body movements and reducing the likelihood of awkward or risky movements that could strain the ACL. Living an active lifestyle plays a vital role in preventing ACL injuries. Regular physical activity, such as walking, cycling, or swimming, helps keep the muscles, ligaments, and joints strong and flexible, which in turn supports overall knee stability. Staying active also improves cardiovascular health and enhances coordination, balance, and agility, all of which are essential for preventing injuries during sports and daily activities. In addition to traditional exercises, incorporating functional movements like balance training, agility drills, and multi-directional exercises can further enhance joint function and reduce the risk of ACL injury. By maintaining an active routine that prioritizes joint health, individuals can reduce the likelihood of sustaining serious knee injuries over time.
How to Treat ACL Injuries
There are several effective treatments for recovering from an ACL injury, each offering unique benefits. Based on research, three key treatments that can be advised by physical therapists have been proven to help those healing from this injury: strengthening exercises, stretching, and Physical therapy, while getting better and solving the original reason for the injury. At Austin Manual Therapy Associates, we offer a comprehensive approach to ACL injury recovery, utilizing proven treatments to help you heal and return to your daily activities safely. Our therapists guide you through specific lower-body stretches targeting the quadriceps, hamstrings, calves, glutes, and hips to relieve tightness and prevent stiffness. You’ll receive a tailored stretching routine with recommendations for frequency and duration, progressing as your recovery advances.
Strengthening Exercises
Strengthening exercises play a crucial role in both the prevention and rehabilitation of ACL injuries. Focusing on key muscle groups such as the quadriceps, hamstrings, glutes, and core muscles can enhance stability, reduce strain on the ACL, and improve overall joint function. Below are some recommended strengthening exercises:
Quadriceps Strengthening: Leg extensions, step-ups, and wall sit help develop the quadriceps, which assist in knee stabilization.
Hamstring Strengthening: Leg curls, Romanian deadlifts, and bridges target the hamstrings, reducing strain on the ACL.
Glute Activation: Squats, lunges, and hip thrusts improve glute strength, which supports knee stability.
Core Stability: Planks, side planks, and bird dogs enhance overall balance and movement control.
Proprioception & Balance Training: Single-leg stands, Bosu ball exercises, and agility drills improve coordination and neuromuscular control.
Performing these exercises consistently, with gradual progression, will contribute to improved knee resilience and a reduced risk of ACL injuries.
Physical Therapy
Most clinics across the United States consider the first eight weeks of treatment the standard care period for ACL injuries. At Austin Manual Therapy Associates, we take pride in having fellowship-trained physical therapists specializing in advanced techniques and individualized care for our patients. After the initial eight weeks, patients typically enter the recovery phase, which can last anywhere from 10 months to a year, depending on the individual’s progress and rehabilitation needs.
Our approach at Austin Manual Therapy Associates is centered on addressing the root causes of the ACL tear rather than just focusing on the symptoms. Our goal is not only to restore the function of the knee but to make the patient stronger and more resilient than they were before the injury, and to solve the reason why the injury was caused in the first place. One of the key factors we focus on during rehabilitation is muscle strength and activation, particularly in the gluteus medius and hamstrings.
The gluteus medius plays a crucial role in stabilizing the hip and knee, while the hamstring, which attaches to the lateral side of the knee, works in coordination with the ACL. Weakness or imbalance in these muscle groups can put excess strain on the ACL and surrounding structures, making the knee more vulnerable to injury. Our treatment approach includes targeting these specific muscle groups to help improve strength, stability, and overall movement patterns, reducing the risk of re-injury and promoting a faster and more effective recovery.
By focusing on building a strong foundation of muscle support, we aim to not only help our patients recover but also optimize their performance, ensuring they can return to their activities stronger and more confident than before the injury.
When to see a Physical Therapist
It's important to see a physical therapist as soon as possible after an ACL tear, especially if you're dealing with significant pain, swelling, or difficulty moving the knee. The sooner you begin rehab, the better the chances of restoring strength, mobility, and function to the knee.
Here are some key signs that it’s time to see a physical therapist:
Post-Surgery Rehab: If surgery is required for the ACL tear, physical therapy is crucial after the procedure to regain range of motion, strength, and function.
Pre-Surgery Rehab: If surgery isn’t immediately necessary or you're managing an ACL tear conservatively, starting physical therapy can help you strengthen the surrounding muscles and improve stability before the procedure.
Weakness or Instability: If the knee feels unstable, weak, or like it might "give out," a physical therapist can guide exercises that will improve strength and stability.
Limited Range of Motion: If you're having trouble bending or straightening your knee, therapy can help restore movement.
Pain Management: A physical therapist can offer techniques to manage pain, improve swelling, and prevent further injury.
Seeing a Physical Therapist early on can also help with injury prevention in the future, especially if you're planning to return to a high-demand sport like soccer. If the injury is recent, it's worth starting as soon as you feel ready or once you're cleared by your doctor.
