LATERAL ANKLE SPRAIN IN ATHLETES: What the current research evidence really suggests

Ankle Sprains: More Than Just a “Simple Twist”

A sudden roll, a sharp twist, and Boom! Your game is on pause. Ankle sprains are often dismissed as minor bumps in everyday life, but in the world of sports, they can be a game-changer. What starts as a sudden twist can sometimes lead to long-term problems like repeated sprains, persistent instability, or even end up in surgery if not properly managed.

Fast-paced sports like football, basketball, netball, and handball put athletes at risk of ankle sprains, with rapid cuts, jumps, and sudden stops pushing the ankle to its limits. Around 75% of these injuries target the lateral ligaments, making them the most common ankle injury in football.

In this blog, we’ll take you through everything you need to know about ankle sprains, from assessment, early diagnosis, rehab strategies, to return-to-sport decisions. Understanding the latest evidence can guide you to protect your ankles and get back in the game smarter and faster by understanding the difference between a quick recovery and a lingering problem.

The Assessment

History matters the most: 

A thorough history is the cornerstone of every assessment. Understanding the story behind the injury can reveal a lot and often provides critical insights. A careful assessment can uncover key information, such as:

  • Mechanism of injury – Was the ankle twisted, subjected to a fall, or hit directly?
  • Weight-bearing capacity – Were you able to stand or walk immediately after the injury?
  • Sensations during the injury – Did you hear a popping sound or experience instability in the joint?
  • Previous injuries– Have you had prior sprains or ankle problems that could affect recovery?
  • Red flag symptoms – Are you experiencing locking, catching, numbness, or tingling, which may indicate more serious complications?

 

A well-documented history, combined with a structured physical exam, often offers more diagnostic value than imaging alone, guiding effective and timely care.

Ottawa Ankle Rules (OAR):

The Ottawa Ankle Rules help doctors decide if an ankle X-ray is necessary. According to OAR, radiological  imaging is recommended only when a patient has:

  • Pain around the posterior edge or tip of the lateral malleolus (outside of the ankle), or
  • Pain around the posterior edge or tip of the medial malleolus (inside of the ankle).
  • Inability to bear weight – Not being able to walk four steps, both right after the injury and during the examination at the hospital.

Why Do These Rules Matter?

According to a systematic review, OARs have consistently demonstrated high sensitivity in ruling out ankle fractures, making them a reliable first-line screening tool. So, they are helpful for:

  • Reducing unnecessary X-rays – Avoid over-testing and extra radiation when it’s not needed.
  • Speeding up care – Faster decision-making helps patients get the right treatment sooner.
  • Co-relating with clinical judgment – When combined with professional expertise, OAR ensures safer, smarter care. 

Use of special tests: What You Need to Know

  • Accuracy is limited – No single test consistently delivers accurate, reliable or valid results.
  • Some tests are useful but never in isolation – A 2022 systematic review by Smith J, et al. shows that Anterior drawer, anterolateral palpation, and reverse anterolateral drawer have either good sensitivity or specificity, but aren’t definitive on their own.
  • Clinical expertise is key –  Tests should be interpreted alongside the patient’s history and symptoms to ensure a more accurate diagnosis and effective care. (2)

The Imaging

Know when to Image

  • X-ray: Only when OAR is positive
  • Ultrasound: Dynamic, cost-effective, and good for visualising ligament tears, joint effusion, or peroneal tendon pathology.
  • MRI: Gold standard if symptoms persist beyond 4–6 weeks or when suspecting osteochondral lesions, syndesmotic injuries, or unexplained instability.

Start with clinical judgment and OAR. Escalate to imaging only when red flags or persistent dysfunction suggest “something more than a sprain”.

The Treatment

Does Ice Actually Help?

Clinician’s note: Ice has long been prescribed to reduce pain and swelling. But a 2021 systematic review found no clear benefit for pain, swelling, range of motion, or function compared with other treatments.

Athlete’s Takeaway: Ice may provide temporary relief from pain, but it doesn’t speed up healing or prevent further injury. Use it for comfort if needed, but focus more on structured rehab and movement rather than relying on cold therapy alone. (3)

What About Compression Bands? 

Clinician’s note: Compression bandages have been widely used in the past, but current research does not support them as a standalone treatment for acute ankle sprains. While compression may offer subjective support, it does not improve clinical outcomes.

Athlete’s Takeaway: Compression wraps may provide a sense of support, but they won’t necessarily speed up your recovery. So, focus on active rehabilitation and movement instead. (4)

Should I Do Weight-Bearing or Not?

Clinician’s Note: Strong evidence supports early, supported weight-bearing even in Grade III injuries. Early weight bearing using aids like lace-up or semi-rigid braces encourages faster pain reduction, mobility, and swelling control compared to rigid immobilisation.

Athlete’s Takeaway: Start walking as soon as it feels safe, with support if needed. The sooner you move, the better your recovery. (5)

So, what can be done?

As per the Clinical Practice Guidelines 2021,  

✅ Strongly Advised

Early protected activity: Gradual return to function with the help of external support (semi-rigid braces, taping)  if needed in the early phase, but it isn’t a long-term solution.

Early supervised rehabilitation: Therapeutic exercises for strength, balance, and coordination speed recovery and reduce time away from sport. Careful monitoring ensures better outcomes.

Tailored rehab program: Customised to the individual’s injury, goals, and recovery; progression guided by symptoms 

 

➖ Can Be Considered

– Manual therapy & joint mobilisation: Offers short-term relief when combined with exercises, but shouldn’t be used alone.

❌  Not Necessary

– Electrotherapy, diathermy, ultrasound: Limited and inconsistent evidence; should only be used as adjuncts, not as core treatments.

– Long-term immobilisation: Rarely needed except in severe injuries or fractures; delays functional recovery. (6)

When do I have to consider surgery?

Surgery is considered when severe ankle instability or failed conservative rehab prevents patients from returning to their desired activities. It’s most commonly recommended for chronic lateral ankle instability (CLAI), where repeated sprains lead to persistent instability, reduced performance, and impaired function. As indicated in a systematic review, surgery offers excellent outcomes, with most athletes returning to sport within a few months, but factors like age and BMI must be considered, and recovery should also address psychological readiness and sport-specific rehab for the best long-term results. (7)

The Return To Sports

Returning to sport after an ankle sprain is often the biggest milestone for athletes, and is also the stage with the highest risk of re-injury if not handled carefully. Current evidence-based approaches ensure that athletes don’t just return quickly, but return safely, with reduced risk of setbacks and stronger long-term performance.

PAASS framework:

The PAASS framework provides a structured, evidence-based approach for guiding return-to-sport decisions following an acute lateral ankle sprain developed through an international multidisciplinary consensus using the Delphi method. (8)

CategoryWhat to AssessObservable Factors / Cut-offs
P – Pain severityPain during sport participation
Pain over the last 24 hours
Pain > 4/10 during activity
Pain persists > 24–72 hours → may indicate incomplete healing
A – Ankle impairmentsAnkle range of motion (dorsiflexion, plantarflexion, inversion, eversion)
Ankle muscle strength, endurance, and power
Dorsiflexion < 20–25°
Plantarflexion < 30–40°
Strength deficit > 20% compared to non-injured limb
Power deficit > 15–20%
A – Athlete perceptionPerceived ankle confidence/reassurance
Perceived ankle stability
Psychological readiness to return to sport
Self-reported readiness scale < 7/10
Avoidance of cutting or jumping drills
Fear of reinjury interfering with performance
S – Sensorimotor controlProprioception
Dynamic postural control and balance
Single-leg stance < 30 seconds
SEBT anterior reach < 4 cm deficit compared to uninjured limb
Poor corrective reactions during perturbations
S – Sport / Functional performanceHopping and jumping ability
Agility
Sport-specific activities
Ability to complete a full training session without symptoms
Limb Symmetry Index (LSI) < 90%
Inability to perform or compensations in:
– Single-leg hop for distance
– Triple hop
– Side hop test
– Agility T-test
Unable to train at full intensity

Ultimately, return-to-sport decisions after an ankle sprain should be guided by a comprehensive, multidimensional assessment rather than relying on a single test or measure. Frameworks like PAASS remind clinicians to consider pain, functional impairments, sensorimotor control, athlete confidence, and sport-specific performance together and never based on time alone. Combined with clinical judgment and individualised rehab progress, this approach ensures safety and supports a confident, sustainable return to play.

 

Is the limb symmetry index enough for decision-making?

While the Limb Symmetry Index (LSI) has long been used to guide return-to-sport decisions, recent evidence suggests it cannot tell the full story on its own. Athletes can achieve symmetrical scores yet still have subtle deficits in balance, agility, or power that increase re-injury risk.

 

To make return-to-sport decisions safer and more individualised, LSI should be combined with functional performance testing, including

 

  • Y-Balance Test 
  • Star Excursion Balance Test
  • Single Leg Squat
  • Side Hop Test
  • Figure-of-8 Hop
  • Modified Agility T-Test
  • Single Hop for Distance
  • Triple Crossover for Distance

 

Research evidence advocates that this multidimensional approach captures both strength and movement quality, ensuring better accurate evaluation of readiness for returning to play. (9)

The Prognosis

Most patients can experience pain relief and improved function within two weeks after a lateral ankle sprain, but recovery can vary. Studies show that 5–33% still experience pain after one year, and 5–25% have symptoms even after three years. Around 50–85% fully recover within three years, regardless of the sprain’s severity. Persistent instability beyond a year may lead to chronic ankle instability, affecting up to 33% of cases. Early, structured rehabilitation is the strongest factor in determining long-term recovery rather than the initial injury severity. (6)

The Risk of Re-injury

Recurrent ankle sprains are a common challenge, especially for athletes returning to sport after an initial injury. The report says that several factors may influence this risk, such as 

  • Higher BMI
  • Delayed or insufficient rehab
  • Persistent ankle instability
  • Poor pain management (10)

Gender-Specific Risk Factors: 

What’s more interesting is that the risk factors differ between men and women

  • Men: Weak hips, poor balance, higher body weight
  • Women: Limited ankle strength

These insights highlight the need for gender-specific assessments and tailored prevention strategies, helping athletes break the cycle and stay strong, confident, and injury-free. (11)

Personalisation is the Key:

Even though recent studies strongly recommend exercise-based rehabilitation significantly lowers the risk of re-injury compared to usual care, it’s never a one-size-fits-all approach. The type, intensity, volume, frequency and type of exercises need to be tailored to each person’s unique needs to ensure the best and safest return to sport. (12)

The Wrap Up

Ankle sprains may seem simple, but the journey from injury to safe return to sport is far from straightforward. 

 

Successful recovery is not just about exercises; it’s about holistic care, which means addressing not only strength, balance, and movement quality, but also rest, sleep, nutrition, mental readiness, and other lifestyle habits that influence healing and recovery.

 

The key is listening to the body, following structured rehabilitation, and making every decision thoughtfully. With the right combination of exercises, guidance, supportive strategies, and overall wellness, most people can recover completely, prevent future injuries, and regain confidence in their activities and sports. 

 

Every ankle has its own story. Approach it wisely, progress steadily, and you’ll not only heal, but also come back stronger and more resilient.
