An ankle can twist during an ordinary walk, a weekend workout, or a competitive game. An ankle sprain occurs when the ligaments that support the joint are stretched or torn, and it is a familiar injury for people of nearly every age and activity level. Many people shake it off, while others find that it keeps them from normal activity for weeks.
So how common are ankle sprains? They are among the most common musculoskeletal injuries, but the exact numbers depend on age, activity, how researchers define and count an injury, and whether the data come from sports teams, the general population, or hospital records. This guide walks through seven key facts, explains what each statistic does and does not measure, and shows how the research connects to prevention.
Understanding how often sprains happen, and to whom, can help you recognize your own risk. Completing rehabilitation and addressing risk factors may also lower the chance of a repeat injury. This article provides general information, not individualized medical advice.
Quick answer: Ankle sprains are among the most common musculoskeletal injuries. How frequently they occur depends on age, activity, and how cases are counted. Research shows that sports involving jumping and rapid direction changes can carry increased risk, while previous ankle sprains may raise the chance of another injury. Strength, balance training, and proper rehabilitation can help reduce risk.
How to Read Ankle Sprain Statistics
Different studies measure different things, so their numbers should not be treated as interchangeable. Keeping three kinds of figures apart makes the research easier to interpret.
| Type of figure | What it describes | Limitation |
|---|---|---|
| Incidence in research studies | New injuries in a defined group over time or exposure, such as athletes in a season | May not reflect people outside the studied group |
| Prevalence | How many people have the condition or history at a point or period in time | Depends on how and when people are asked |
| Emergency-department (ED) cases | Injuries treated in hospital emergency departments | Misses sprains managed at home, in clinics, or not treated at all |
Rates measured per person-year, per athlete exposure, and per hour of play are also not directly comparable with one another. The sections below identify the population and setting behind each statistic.
7 Key Facts About Ankle Sprains
1. Ankle Sprains Are Among the Most Common Musculoskeletal Injuries
Ankle sprains are frequently reported in both sports and everyday life. A systematic review and meta-analysis published in Sports Medicine in 2014 pooled 181 prospective studies and identified ankle sprain as a common musculoskeletal injury.
No single global figure is definitive. The total depends on whether researchers count every injury, only sports-related cases, or only those treated in healthcare settings. Studies that miss minor or untreated sprains tend to underestimate how often they occur.
2. Millions of Ankle Sprains Are Treated in U.S. Emergency Departments
A recent study of U.S. national data, The National Epidemiology of Ankle Sprains in the United States: Updates From 2010 to 2024, estimated about 7.4 million ankle sprains treated in emergency departments over that period. It estimated an incidence of 1.53 ED-treated ankle sprains per 1,000 person-years.
This number describes ED cases in that study. It is not every ankle sprain that occurred in the United States, and it is not a global total. Many sprains are treated elsewhere or managed at home, so the real number of sprains is higher than any ED count.
3. Teenagers and Young Adults Account for a Large Share of Cases
In the same U.S. emergency-department study, more than half of the cases occurred in people aged 10 to 24. That pattern makes sense, because many young people play sports that involve jumping, running, and rapid direction changes.
This finding describes ED data from the United States, not all ankle sprains everywhere. Sprains happen at every age. Appropriate conditioning and injury-prevention practices can benefit young athletes, and our guide to preventing ankle sprains covers practical steps.
4. Sports With Jumping and Rapid Direction Changes Can Carry Higher Risk
Basketball, volleyball, soccer, and other activities that involve jumping, landing, and sudden turns expose the ankle to more twisting forces. An awkward landing or contact with another player’s foot can make the ankle roll. In the 2014 systematic review, indoor and court sports had the highest incidence.
Not all sports carry the same injury rate. Risk also depends on the level of play, playing surface, conditioning, and previous injury. Rates reported per athlete exposure or per hour of play should not be compared directly across studies.
5. The Outer Ankle Is the Most Commonly Injured Area
Lateral ankle sprains involve the ligaments on the outside of the ankle and typically happen when the foot rolls inward. The 2014 systematic review found lateral sprains were the most commonly observed type. The American Academy of Family Physicians (AAFP) also notes that most ankle sprains are inversion injuries of the lateral ligaments.
Medial sprains, on the inner side, and high ankle sprains, which involve the ligaments above the ankle joint, are less common. Symptoms alone cannot reliably identify which ligament is injured, so a clinician needs to examine the ankle. Our guides to ankle sprain symptoms in men, in women, and in older adults can help you recognize the signs of an ankle sprain.
6. A Previous Ankle Sprain Can Increase the Risk of Another
An earlier sprain may leave persistent weakness, reduced balance, or instability if recovery is incomplete. Mayo Clinic lists a previous ankle injury among the risk factors for a sprained ankle. This is one reason a gradual return to activity and full rehabilitation matter.
Balance training, strengthening, and suitable ankle support are possible prevention measures, and a clinical practice guideline in the British Journal of Sports Medicine discusses them for recurrent sprains. Not everyone who has had a sprain will have another.

7. Ankle Sprains Can Affect People Outside Competitive Sports
Sprains also happen during walking, exercise, household chores, and other everyday movements. An uneven sidewalk, a misstep on stairs, or an awkward landing can be enough. Mayo Clinic notes that walking on an uneven surface is a recognized risk factor. See our article on what causes ankle sprains for more examples.
Sports studies and emergency-department studies do not capture every injury that happens in daily life. Take ankle pain, substantial swelling, or difficulty bearing weight seriously, whatever caused the injury.
What Do Ankle Sprain Statistics Mean for Prevention?
Statistics show the scale of the problem, but they cannot predict whether you will be injured. These practical lessons follow from the research:
- Build ankle and lower-leg strength gradually.
- Practice balance and coordination exercises.
- Warm up before demanding physical activity.
- Wear footwear appropriate for the activity.
- Consider suitable bracing or taping when recommended, especially after a previous sprain.
- Complete rehabilitation before returning to intense exercise.
- Seek medical assessment for severe pain, deformity, inability to bear weight, or a cold, numb, or discolored foot.
Prevention strategies can reduce risk, but they cannot guarantee that an ankle sprain will never occur. The evidence is stronger for lowering the risk of repeat sprains than for preventing a first one.

When Should You Seek Medical Attention?
A suspected sprain can sometimes be a fracture or another injury, and symptoms alone cannot tell them apart. Seek prompt medical assessment if you:
- Cannot bear weight or walk
- Have severe or worsening pain
- Develop major swelling
- Notice an unusual ankle shape
- Have numbness or changes in foot color or temperature
Persistent pain or repeated ankle instability should also be evaluated. Mayo Clinic explains how a sprained ankle is diagnosed and treated, and our overview of ankle sprain treatment options covers care in more detail.
Frequently Asked Questions About Ankle Sprains
How common are ankle sprains?
They are among the most common musculoskeletal injuries, but no single figure fits every group. One U.S. study estimated about 7.4 million emergency-department-treated ankle sprains from 2010 to 2024. Many sprains never reach an emergency department, so that count understates how often they occur.
What age group gets the most ankle sprains?
In the U.S. emergency-department study, more than half of cases were in people aged 10 to 24. The 2014 systematic review also reported higher incidence in children and adolescents than in adults. These findings reflect the populations studied; sprains occur at all ages.
Which sports have the highest ankle sprain risk?
Sports with jumping, landing, and quick direction changes, such as basketball, volleyball, and soccer, tend to carry more risk. In the 2014 systematic review, indoor and court sports had the highest incidence. Rates vary with level of play, surface, and previous injury, so they should not be compared across studies directly.
Are ankle sprains more common in women or men?
It depends on the group studied. The 2014 systematic review reported a higher incidence in females than in males, but sports participation, exposure, and study methods differ. This finding should not be applied to every woman or man.
Can you sprain your ankle while walking?
Yes. An unexpected twist, a misstep, or uneven ground can sprain an ankle during an ordinary walk. Watching your footing and wearing suitable shoes may help, although no precaution removes the chance of a roll.
Why do ankle sprains happen repeatedly?
A previous sprain can leave weakness, reduced balance, or instability, especially when rehabilitation is incomplete or activity resumes too soon. Other contributors may include footwear, surfaces, and sport demands. A clinician or physical therapist can assess why your ankle keeps giving way.
How can you reduce the risk of an ankle sprain?
Combine balance training, gradual strengthening, warm-ups, suitable footwear, awareness of surfaces, and ankle support when appropriate. Complete rehabilitation after any sprain. The AAFP notes that braces and taping can reduce the risk of sprains during sports. No approach guarantees protection.
When should an ankle sprain be checked by a doctor?
See a doctor if you cannot bear weight, the ankle looks deformed, pain or swelling is severe, or your foot feels numb, cold, or discolored. Also seek care if symptoms are not improving or the ankle repeatedly gives way. Only an examination can rule out a fracture.
Conclusion: Common, but Not Inevitable
Ankle sprains are common, risk varies across activities and populations, and appropriate prevention and rehabilitation can help reduce avoidable injuries. Statistics describe groups, not individuals, so your own risk depends on your activity, history, and conditioning.
If you have pain, ongoing instability, or a recent injury, talk with a healthcare professional about a plan that fits you.
