Ankle impingement treatment depends on where the ankle is being compressed, what caused the problem and which movements reproduce your pain, with physiotherapy often focusing on restoring mobility, strength and movement control.
Does your ankle hurt when you bend it, squat, climb stairs or push off while walking or running?
One possible explanation is ankle impingement, a condition in which bone or soft tissue is compressed around the ankle during particular movements.
The pain may occur at the front, back or side of the ankle depending on which structures are involved.
Quick Answer: Why Does Your Ankle Hurt When You Bend It?
Pain when bending the ankle can have several causes, including ankle impingement, joint stiffness, tendon problems, previous ankle injury or other joint conditions.
With anterior ankle impingement, pain is typically felt at the front of the ankle when the foot moves upward toward the shin. With posterior ankle impingement, pain is more commonly felt at the back of the ankle when the foot points downward.
Physiotherapy can help identify contributing factors such as restricted mobility, weakness, poor movement control or inappropriate loading. Persistent symptoms or suspected structural problems may require medical assessment and imaging.
Ankle impingement is more common in people who repeatedly load the ankle through a limited range, including athletes, dancers and people with previous ankle injuries.
However, pain when bending the ankle does not automatically mean that impingement is the cause.
A physiotherapy assessment can help determine whether the problem is related to joint mobility, muscle weakness, previous injury, movement control, tendon irritation, instability or a structural problem requiring further investigation.
What Is Ankle Impingement?
Ankle impingement occurs when tissues around the ankle become compressed during a particular movement.
The structure involved may be bone, cartilage, synovial tissue, scar tissue, a ligament or a tendon.
This can create a characteristic pattern where the ankle feels relatively comfortable during ordinary movement but becomes painful at a particular point in the range.
Ankle impingement can be broadly described according to its location.
Anterior impingement occurs toward the front of the ankle, while posterior impingement occurs toward the back.
There can also be anteromedial, anterolateral and posteromedial patterns, depending on the structures involved.
Recent research emphasizes that anterior ankle impingement is not a single uniform condition and that different structural and soft-tissue patterns may require different approaches to diagnosis and management. (Yang et al., 2026)
Key Takeaways About Ankle Impingement
- Ankle impingement occurs when tissues around the ankle become compressed during certain movements.
- Anterior impingement commonly causes pain at the front of the ankle during dorsiflexion.
- Posterior impingement commonly causes pain at the back of the ankle during plantarflexion.
- A previous ankle injury can contribute to altered ankle mobility, strength or movement control.
- Pain during squatting does not automatically mean that a bone spur is present.
- Physiotherapy may address mobility, strength, balance, movement control and activity tolerance.
- Imaging may be appropriate when a structural problem is suspected, but scan findings should be interpreted alongside symptoms and clinical examination.
- Persistent pain, locking, swelling or progressive loss of movement should be medically assessed.
Why Does the Ankle Hurt When You Bend It?
The direction of movement and location of pain provide useful clues.
When the foot moves upward toward the shin, the movement is called dorsiflexion.
Pain at the front of the ankle during dorsiflexion can occur with anterior ankle impingement.
When the foot points downward, the movement is called plantarflexion.
Pain at the back of the ankle during plantarflexion can occur with posterior ankle impingement.
For example, a person with anterior impingement may experience pain when performing a deep squat because the ankle requires substantial dorsiflexion.
Someone with posterior impingement may experience pain when repeatedly pointing the foot downward during activities such as dancing, kicking or jumping.
The movement pattern is helpful, but it does not establish a diagnosis by itself.
What Is Anterior Ankle Impingement?
Anterior ankle impingement produces pain toward the front of the ankle and is commonly aggravated by dorsiflexion.
People may notice symptoms during:
- Deep squats
- Lunges
- Stair climbing
- Uphill walking
- Uphill running
- Sprinting
- Jumping and landing
- Repeated ankle bending
The sensation may be described as pinching, catching, pressure or a feeling that something is blocking the ankle.
Anterior impingement can involve bony changes such as osteophytes, but soft-tissue structures can also become involved.
Previous ankle trauma, repetitive loading, instability and degenerative joint changes may contribute to the development of symptoms. (Talusan et al., 2014)
What Is Posterior Ankle Impingement?
Posterior ankle impingement affects structures toward the back of the ankle and is commonly aggravated by plantarflexion.
It is particularly associated with activities involving repeated or forceful pointing of the foot.
Symptoms may occur during:
- Dancing
- Kicking
- Jumping
- Sprinting
- Repeated push-off
- Downhill movement
- Activities requiring deep plantarflexion
One possible contributor is an os trigonum, an accessory bone located behind the ankle.
A prominent Stieda process can produce a similar problem.
The flexor hallucis longus tendon and posterior ankle capsule may also become involved.
Posterior ankle impingement is particularly recognized in athletes and dancers who repeatedly load the ankle in plantarflexion (Ishibashi et al., 2023)
Can an Old Ankle Sprain Cause Ankle Impingement?
An old ankle injury can contribute to the development of symptoms, but it is not the only possible cause.
Following an ankle sprain, some people develop persistent changes in ankle mobility, strength, proprioception or movement control.
Repeated sprains may also contribute to chronic instability and altered loading around the ankle.
These changes can influence how the ankle moves under load and may contribute to symptoms in some individuals.
This is why a physiotherapist should not assess only the painful area.
The examination may also include ankle stability, calf strength, balance, gait, single-leg movement and the history of previous injuries.
What Does Ankle Impingement Feel Like?
Symptoms vary according to the location and structures involved.
Common symptoms include:
- Pain at the front or back of the ankle
- Pinching during a specific ankle movement
- Pain at the end of the available range
- Stiffness
- Reduced ankle movement
- A sensation of catching or blocking
- Swelling after activity
- Pain during squatting
- Pain during running or jumping
- Discomfort during repeated push-off
Some people notice symptoms only during specific activities rather than during normal walking.
That activity-specific pattern can be useful during a physiotherapy assessment because it helps identify which movement or load is reproducing the symptoms.
Why Does Squatting Cause Front-of-Ankle Pain?
A deep squat requires the ankle to move into dorsiflexion while the foot remains in contact with the floor.
If the front of the ankle becomes painful during this movement, anterior impingement is one possible explanation.
However, front-of-ankle pain during squatting does not prove that there is a bone spur.
Restricted ankle mobility, joint stiffness, previous injury, altered foot mechanics and other musculoskeletal conditions can also affect the way the ankle behaves during a squat.
A physiotherapist may compare ankle movement during different weight-bearing positions and assess whether the restriction changes with technique, foot position or loading.
This helps distinguish a mobility problem from pain associated with compression or another underlying condition.
How Is Ankle Impingement Diagnosed?
Diagnosis begins with a detailed history and physical examination.
A physiotherapist may ask:
- Where exactly is the pain?
- Which ankle movement causes it?
- Did the symptoms begin after an injury?
- Does squatting reproduce the pain?
- Does running aggravate it?
- Is there swelling?
- Does the ankle feel unstable?
- Does the ankle catch or lock?
- Has ankle movement gradually become more restricted?
The physical assessment may include:
Ankle Range of Motion
Dorsiflexion and plantarflexion can be assessed in both weight-bearing and non-weight-bearing positions.
Muscle Strength
Calf and ankle muscle strength may be assessed to determine whether reduced capacity is contributing to poor load tolerance.
Joint and Soft-Tissue Assessment
The physiotherapist may assess how the ankle and surrounding tissues respond to movement and loading.
Balance and Proprioception
Previous ankle injuries can affect sensorimotor control, so single-leg balance may be relevant.
Functional Movement
Squatting, stepping, hopping or running may be assessed when appropriate.
The purpose is not simply to reproduce pain. The aim is to understand why the pain occurs and what factors are modifiable.
Does Ankle Impingement Need an X-Ray or MRI?
Not every person with ankle pain needs imaging.
The decision depends on the clinical presentation and whether a structural problem is suspected.
X-rays can be useful when bony abnormalities such as osteophytes or other osseous changes are suspected.
MRI can provide information about cartilage, bone marrow changes and soft-tissue structures.
Ultrasound can also be useful for assessing certain superficial or dynamic soft-tissue problems.
Importantly, imaging findings should be interpreted alongside symptoms and physical examination.
This is particularly important with posterior ankle impingement.
A systematic review found insufficient evidence to establish a reliable relationship between imaging findings and symptoms because suitable comparisons between symptomatic and asymptomatic individuals were lacking. (Baillie et al., 2022)
Can Physiotherapy Help Ankle Impingement?
Yes, physiotherapy can be an important part of conservative management, particularly when symptoms are influenced by modifiable factors such as restricted mobility, weakness, poor movement control or inappropriate loading.
However, physiotherapy should not be presented as a universal cure for every type of impingement.
The treatment depends on what the assessment identifies.
A physiotherapist may use:
- Activity modification
- Progressive strengthening
- Ankle mobility exercises
- Balance and proprioception training
- Movement retraining
- Running or sport-specific rehabilitation
- Manual therapy when clinically appropriate
- Gradual return to activity
The objective is to improve the ankle’s ability to tolerate the movements required for everyday activities and sport while reducing unnecessary irritation.
What Exercises Can Help Ankle Impingement?
There is no single exercise routine that is appropriate for every person with ankle impingement.
Exercise selection should depend on the location of symptoms, the suspected tissue involved, mobility restrictions, strength deficits and the person’s functional goals.
Potential exercises may include:
Controlled Ankle Mobility
Gentle dorsiflexion or plantarflexion movements can be introduced when mobility is restricted and the movement can be performed without significantly aggravating symptoms.
Calf Raises
Progressive calf strengthening can improve the capacity of the ankle and lower leg to tolerate walking, running and other loading activities.
Bent-Knee Calf Raises
This variation can provide a different loading stimulus to the calf complex and may be incorporated according to the individual’s assessment.
Step-Down Exercises
Step-downs challenge ankle and lower-limb control during weight-bearing and can help bridge the gap between isolated exercises and functional movement.
Single-Leg Balance
Balance exercises may be appropriate when previous ankle injury has affected sensorimotor control.
Functional Squatting
If squatting is painful, the movement can sometimes be modified by adjusting depth, load or technique before gradually rebuilding tolerance.
The goal is progressive capacity, not repeatedly forcing the ankle into a painful end position.
Should You Stretch an Ankle That Hurts When You Bend It?
Not automatically.
If pain is caused by compression at the end of a joint’s range, repeatedly forcing the ankle further into that position may irritate the symptoms.
Stretching may be useful when a genuine mobility restriction is contributing to the person’s movement problem, but this should be established through assessment.
An ankle that feels “tight” does not necessarily need aggressive stretching.
The limitation could be related to pain, joint stiffness, altered mechanics or a structural restriction.
Myth vs Fact: Ankle Impingement
Myth: Every stiff ankle needs aggressive stretching.
Fact: An ankle that feels tight may have several possible causes. If pain is related to compression at the end of the joint’s range, repeatedly forcing the ankle further may aggravate symptoms.
Myth: Front ankle pain during a squat always means a bone spur.
Fact: Front-of-ankle pain can have several causes, including mobility restrictions, joint stiffness, previous injury and other musculoskeletal problems.
Myth: An MRI showing an abnormality automatically means surgery is needed.
Fact: Imaging findings need to be interpreted alongside symptoms, physical examination and functional limitations. An abnormal scan does not automatically identify the cause of pain or determine the need for surgery.
Myth: Physiotherapy for ankle impingement only involves stretching.
Fact: Physiotherapy may include activity modification, progressive strengthening, mobility work, balance training, movement retraining and gradual return to activity depending on the assessment.
Myth: You should completely stop all activity until the ankle is pain-free.
Fact: Some people can continue modified activity while symptoms are managed. The appropriate activity level depends on symptom severity, the underlying condition and professional assessment.
Can Manual Therapy Improve Ankle Movement?
Manual therapy may be used as an adjunct to exercise-based rehabilitation.
Joint mobilisation techniques can produce short-term improvements in ankle dorsiflexion in some populations. However, the certainty of evidence remains limited.
A 2025 systematic review and meta-analysis found an improvement in dorsiflexion following manual therapy compared with sham treatment, but rated the certainty of evidence as very low because of heterogeneity, limited trials and imprecision. (Loures de Paula et al., 2025)
For this reason, manual therapy should generally be viewed as one component of rehabilitation rather than a replacement for progressive exercise, movement retraining and appropriate activity modification.
What Does Physiotherapy Rehabilitation Look Like?
A useful rehabilitation program usually progresses according to the person’s symptoms and physical capacity.
Stage 1: Reduce Unnecessary Irritation
Activities that repeatedly reproduce sharp or escalating pain may be temporarily modified.
This does not necessarily mean complete rest.
The aim is to maintain appropriate movement and activity while reducing excessive aggravation.
Stage 2: Restore Mobility and Strength
Where appropriate, the physiotherapist addresses restricted ankle movement and develops calf and ankle strength.
Stage 3: Improve Balance and Movement Control
Single-leg balance, controlled stepping and functional exercises can be introduced when relevant.
Stage 4: Restore Higher-Level Loading
For active individuals, rehabilitation may progress to hopping, landing, running, jumping or sport-specific movements.
Stage 5: Return to Normal Activity
The final stage involves gradually increasing exposure to the movements and loads that previously caused symptoms.
This progression is individualized rather than based on a fixed number of days.
Can You Keep Running With Ankle Impingement?
Some people may be able to continue modified running, while others may need a temporary reduction in running.
The decision depends on the severity and behavior of symptoms.
Running may need modification if it consistently causes increasing pain, swelling, loss of movement or a worsening sensation of mechanical blockage.
Possible adjustments include:
- Reducing running distance
- Reducing speed
- Temporarily avoiding hills
- Changing training frequency
- Choosing a more predictable running surface
- Adding recovery days
- Continuing appropriate strengthening
The objective is not simply to stop running indefinitely.
It is to find a level of activity that the ankle can tolerate while rehabilitation addresses the underlying problem.
What About Athletes and Runners?
Athletes may need additional assessment because their ankles experience higher and more repetitive loads.
A runner may need to tolerate repeated dorsiflexion during stance and push-off, while a dancer or footballer may repeatedly move into plantarflexion.
Therefore, rehabilitation should eventually reflect the actual demands of the person’s sport.
A runner may progress from walking and controlled strengthening to jogging, faster running, hills and eventually sport-specific training.
A dancer may require progressive exposure to plantarflexion and pointe-related positions where appropriate.
The final rehabilitation stage should therefore be activity-specific, rather than simply based on being pain-free during ordinary walking.
When Might Surgery Be Considered?
Surgery is not automatically required when ankle impingement appears on an X-ray or MRI.
Conservative treatment is often considered initially when clinically appropriate.
If symptoms persist despite appropriate non-surgical management, or if a significant structural abnormality is clearly contributing to persistent symptoms, an orthopaedic or foot-and-ankle specialist may consider surgical options.
A systematic review of ankle impingement treatment found that arthroscopic management can provide favorable outcomes in appropriately selected patients, although outcomes depend on the type of impingement and underlying pathology. (Hamberger et al., 2025)
Arthroscopic treatment can be effective for appropriately selected patients with anterior ankle impingement, particularly when a structural lesion is responsible for persistent symptoms. (Talusan et al., 2014)
However, the presence of an abnormality on imaging should not be interpreted in isolation.
The decision should consider symptoms, examination findings, functional limitations, imaging and response to conservative treatment.
What Happens After Ankle Impingement Surgery?
Physiotherapy remains important after surgery.
Rehabilitation may include:
- Managing postoperative swelling
- Restoring ankle movement
- Gradually rebuilding strength
- Improving balance
- Restoring walking mechanics
- Progressing to running or sport-specific activities
The exact progression depends on the procedure performed and any additional pathology that was treated.
The aim is not simply to regain movement but to rebuild the capacity needed for the person’s normal activities.
How Is Ankle Impingement Different From Other Ankle Problems?
Ankle pain during bending can have many causes.
For example, Achilles tendon problems can cause pain toward the back of the ankle, while ankle arthritis may cause stiffness and pain with loading.
A previous sprain may produce chronic instability.
Tendon disorders, osteochondral lesions, fractures and other joint conditions can also produce pain during ankle movement.
This is why self-diagnosing every painful squat or lunge as “ankle impingement” can be misleading.
The location of pain, mechanism of onset, aggravating movements and physical examination all matter.
When Should You See a Physiotherapist?
A physiotherapy assessment is worthwhile if:
- Ankle pain repeatedly occurs when bending the ankle
- Squatting consistently causes pain
- The ankle feels blocked or catches
- Running repeatedly aggravates the symptoms
- You have a history of ankle sprains
- The ankle feels unstable
- Movement has become progressively restricted
- Swelling returns after activity
- The symptoms are affecting exercise or daily activities
A physiotherapist can assess whether the presentation is consistent with impingement or whether another condition should be investigated.
When Should You Seek Medical Assessment?
Some presentations require medical assessment rather than self-management.
Seek prompt medical care after significant trauma, if the ankle is visibly deformed, if you cannot bear weight, if pain is severe or rapidly worsening, or if there is significant unexplained swelling.
Persistent locking, recurrent swelling, progressive loss of movement or symptoms that fail to improve should also be assessed.
If a structural lesion is suspected, medical imaging or referral to an orthopaedic or foot-and-ankle specialist may be appropriate.
Can Ankle Impingement Be Prevented?
Not every case can be prevented, particularly when structural or degenerative changes are involved.
However, maintaining ankle strength, mobility and movement control may help reduce modifiable contributors to symptoms.
For people with previous ankle sprains, appropriate rehabilitation is particularly important.
The clinical practice guideline for lateral ankle sprains and chronic ankle instability supports therapeutic exercise, including strength, balance and movement-control interventions, as part of evidence-based ankle rehabilitation. (Martin et al., 2021)
Prevention should therefore focus on maintaining adequate physical capacity rather than trying to force the ankle into extreme ranges of motion.
A Physiotherapist’s Approach to Painful Ankle Bending
When a patient says, “My ankle hurts when I bend it,” the first question should not be, “Which stretch should I give?”
The more useful questions are:
Where does it hurt?
Which direction reproduces the pain?
When did it begin?
Was there an injury?
What activities make it worse?
Is the ankle weak, stiff or unstable?
Is there a mechanical restriction?
Does the person need further investigation?
This approach allows treatment to be based on the individual’s presentation rather than assuming that every painful ankle requires the same exercise.
Final Thoughts
Ankle pain when bending can have several causes, and ankle impingement is one possible explanation. Anterior ankle impingement is typically associated with pain toward the front of the ankle during dorsiflexion, while posterior ankle impingement more commonly causes pain toward the back during plantarflexion.
Physiotherapy can be valuable when symptoms are influenced by restricted mobility, weakness, poor movement control, previous injury or inappropriate loading. Treatment may include activity modification, progressive strengthening, mobility work, balance training and gradual return to normal activity.
The goal is not simply to force the ankle to bend further. It is to understand why the ankle hurts during that movement and restore comfortable, functional movement in a way that matches the person’s daily and sporting demands.
