Women & ACL Injuries: Know Risks, Steps for Prevention
August 10, 2021
Whether you’re a casual jogger or elite athlete, you’re at risk for an injury to your anterior cruciate ligament (ACL). If you’re a woman, you are at even greater risk for these injuries.
But there are steps you can take to prevent them.
“Among athletes, women are more than twice as likely to have an ACL injury than men,” says Nithin Natwa, M.D., a sports medicine specialist and primary care physician at Henry Ford Health System. “Once you have an ACL injury, you are at greater risk for having further soft tissue injuries in the future. That’s why it is important to prevent these injuries and follow your treatment plan if injured.”
What Is An ACL Injury?
An ACL injury is a strain or tear in the ACL, one of the four major ligaments that support the knee so it can flex and bend. The ACL is a strong band of tissue that helps connect your thigh bone (femur) to your shin bone (tibia). “An ACL injury usually occurs without contact when you turn suddenly while running or land off-balance on one leg. These actions overload the knee joint and cause the ACL to be torn,” says Dr. Natwa.
In the United States, 100,000 people have ACL injuries each year. Anyone can experience an ACL injury, though athletes participating in sports like football, basketball, soccer and gymnastics are at highest risk. And summer is a peak time for outdoor sports injuries.
Seek immediate care if you have any of these signs of an ACL injury:
• An audible “pop” in the knee
• Intense knee pain and rapid-onset swelling (within hours)
• Loss of range of motion
• An unstable feeling or locking of your knee
The most common treatment for ACL injuries is surgery followed by physical therapy. After treatment, you can expect to return to normal activities in 6 to 9 months. However, peak athletic performance can take up to two years.
Why Are Women At Higher Risk For ACL Injuries?
According to Dr. Natwa, the differences in athletic training techniques for males versus females have left women at greater risk for ACL injuries. “There has been more emphasis on overall conditioning and mechanics for boys participating in sports compared to girls,” he says.
As a result, women are at greater risk for ACL tears and sprains due to:
• Differences in neuromuscular control: Without conditioning from an early age, women may not have the same ability to land and perform athletic motions that men do. For example, women are at higher risk for an ACL injury after landing from a jump.
• Strength imbalance for muscles that support the knee: Female athletes tend to have more defined quadriceps muscles but weaker hamstrings than men, putting them at greater risk for injury.
According to Dr. Natwa, there are many theories about women’s risk for ACL injury that lack scientific evidence, including:
• Width of the pelvis: Some people have suggested that the wider width of a woman’s pelvis puts more pressure on the knee joint and increases the risk for injury. However, this difference has not been shown to impact a women’s risk for ACL tears or sprains.
• Knee anatomy: The ACL runs through a section of the femur called the intercondylar notch. Women tend to have a narrower notch than men. Regardless of gender, individuals who possess smaller notch dimensions appear to be at greater risk for injury than individuals with larger notches.
• Hormones: Men and women have different hormone levels. But there is currently no concrete evidence that female hormones place women at higher risk for ACL injures.
Steps To Prevent ACL Injuries – Conditioning Early, Often
“The best way to prevent ACL injuries is to begin and maintain regular conditioning exercises at an early age,” Dr. Natwa says. “The more frequently you engage in proper exercises, the lower your risk for injury.”
Consult with a sports medicine specialist, physical therapist or athletic trainer to develop a training routine to prevent ACL and other injuries. Your training program should include exercises that:
• Strengthen the muscles that support your knee: Add strength training to build up your calves, hamstrings and quadriceps muscles. These muscles help stabilize your knee as you move. By strengthening these muscle groups evenly, you can lower your risk for injury.
• Improve overall neuromuscular control: Focus on adding neuromuscular exercises that train your nerves and muscles to react and communicate. For example, you may work on your balance by standing on one leg or sit upright on an exercise ball for short periods of time. And core exercises can strengthen the muscles that support your abdomen and back and help improve your posture as you move. These moves can strengthen your joints and help you learn appropriate balance and technique.
“Exercise really is the best medicine. It can improve your balance and agility as you participate in a sport or prevent injury as you move through your daily activities,” says Dr. Natwa. “Consider adding these exercises to your wellness program.”

Macomb Lutheran North Standout on Mend After Knee Injury
October 3, 2023
Macomb Lutheran North freshman Emiliana Manzo has already achieved a long list of accomplishments, including a 3.8 grade-point average while juggling two sports she loves.
As a point guard, she led her basketball team to an undefeated season in its division. She is also a center attacking midfielder, sometimes playing forward, on the 2009 Nationals Girls Academy Blue soccer team, ranked No. 1 in Michigan and 14th in the country.
In June of 2022, Emiliana hit a detour on her sports journey when she was participating in a club soccer national championship in Oceanside, Calif. With a few seconds left in the game and her team up 2-1, she ran 20 yards full speed to get to the ball. Hyperextending her left knee, she felt two pops. It was the first time she experienced an injury.
“I was screaming and crying and got taken off the field on a golf cart,” explains Emiliana. The trainer felt she was OK. Fortunately, she had the next day off and her knee was feeling better. The following day she played again, and 20 minutes into the game she knew there was an issue.
“Someone hit me from behind and I heard the pop again. I knew there was a problem.”
Emiliana’s father Vince Manzo said she experienced swelling, and the athletic trainer thought she may have a meniscus injury; however, she was able to continue to walk around during the championship in California before heading home.
Finding the Right Provider
Back in Michigan, Emiliana saw a few surgeons during her evaluation to seek treatment. When she met with Vasilios Bill Moutzouros, MD, chief of Sports Medicine at Henry Ford Health, she felt she met the right match.
“He treated me like an athlete and made me feel really comfortable,” she says.
Vince adds that both he and Emiliana were also appreciative of something Dr. Moutzouros said during her evaluation: “He emphasized to Emiliana that she was an athlete before this injury, and she would be an athlete after the injury.”
A detailed evaluation by Dr. Moutzouros revealed Emiliana had a complete anterior cruciate ligament (ACL) tear and medial and lateral meniscal tears. The meniscus, a C-shaped piece of tough, rubbery cartilage, acts as a shock absorber between the shinbone and the thighbone. It is one of the most common knee injuries. The ACL, one of the strong bands of tissue that help connect the thigh bone (femur) to the shinbone (tibia), is also prone to injury during sports when there are sudden stops or changes in direction.
Emiliana required physical therapy to get the swelling down and increase mobility before surgical repair.
Dr. Moutzouros reconstructed her ACL with her own patellar tendon graft and repaired her medial meniscus.
“She handled the surgery well and has been working very hard in her rehabilitation,” he says. “Her high-level soccer experience likely helped in her recovery as her range of motion and strengthening advanced so quickly.”
Understandably, Emiliana was nervous and scared when she went into surgery but expressed appreciation for the little things from Henry Ford like hearing “great music” as she was entering surgery, which gave her a sense of calm.
“That’s when I knew I picked the right doctor,” she said.
The Road to Recovery
As part of her recovery, after surgery which took place in July of 2022, Emiliana has undergone six months of physical therapy to increase mobility and strength training to get her leg strong again.
She also participated in the Return to Sport Program at the Henry Ford Center for Athletic Medicine to optimize recovery.
“We loved it,” says Vince. “It gave us peace of mind.”
Dr. Moutzouros explains that ACL prevention and rehabilitation programs are critical, especially for women because they have a four times greater risk of ACL tear than men. He says performance training post-surgery, along with an injury prevention program for those playing cutting sports, can markedly reduce the likelihood of future ACL injury.
“At Henry Ford, we work with physical therapists across the Midwest as well as our own. They do a great job in following our Henry Ford specific post-ACL reconstruction protocol,” he says. “After therapy runs its course, we strongly encourage our athletes to undergo performance training to allow a smooth transition back to sport.”
Nick Parkinson, supervisor of Athletic Training and Sports Performance at Henry Ford Health, emphasizes that the return to sport program is designed to bridge the gap between rehabilitation and returning to full activity in your chosen sport.
“Many times, insurance limits rehabilitation to regaining activities of daily living and not necessarily rebuilding the skills needed to play a sport or return to activity,” Nick says. “This program provides an affordable option to fill this need and return athletes to competition at the highest level.”
As for Emiliana, who hopes to play soccer in college and pursue a career in the medical field, she says this experience has taught her to not be afraid of injuries and treatment. She has also used the experience to volunteer for a program through the Girls Academy which serves as an advisory board to come up with ideas to help with mental and physical issues girls her age may be facing.
“For other kids who experience injuries, I’ve learned that this does not define you,” she said. “You can push through it, recover from it and be way better than you even were before.”
