Pain along the inside of your ankle, discomfort around your foot arch, or difficulty standing on your toes can sometimes indicate posterior tibial tendon dysfunction. This condition affects an important tendon that helps support the arch of your foot and maintain ankle stability.
The posterior tibial tendon runs along the inside of your ankle and attaches to bones within your foot. It plays an important role in controlling foot movement and supporting your arch when walking, running, and standing.
When this tendon becomes irritated, weakened, overstretched, or damaged, it may cause pain and changes in foot shape. In some cases, the arch gradually becomes flatter, making everyday activities more difficult.
In this guide, we explore seven helpful tips for managing posterior tibial tendon dysfunction, understanding its symptoms, and how physiotherapy may support foot and ankle rehabilitation.
What Is Posterior Tibial Tendon Dysfunction?
Posterior tibial tendon dysfunction (PTTD) is a condition affecting the tendon that runs behind the inner ankle bone and underneath the foot.
This tendon helps:
Support the natural arch of the foot.
Stabilise the foot during walking.
Control inward movement of the foot.
Assist with standing on your toes.
Maintain balance during everyday activities.
When the tendon becomes damaged or loses its ability to function effectively, it may no longer provide sufficient support to the foot arch.
This can contribute to a condition known as adult-acquired flatfoot or progressive collapsing foot deformity.
Possible contributing factors include:
Repeated stress on the tendon.
Previous ankle injuries.
Sudden increases in physical activity.
Age-related tendon changes.
Certain foot structures.
Inflammatory conditions.
Increased mechanical loading on the foot.
The condition may develop gradually rather than following one specific injury.
Early assessment is important because symptoms and changes in foot structure can become more significant over time.
Common Symptoms of Posterior Tibial Tendon Dysfunction
Symptoms can vary depending on the severity of tendon involvement.
Common signs include:
Inner ankle pain: Discomfort behind or below the inner ankle bone.
Foot arch pain: Aching along the inside of the foot.
Swelling: Swelling or tenderness around the affected tendon.
Flattening of the arch: A noticeable change in the shape of the foot.
Walking difficulties: Pain or fatigue during prolonged walking.
Reduced strength: Difficulty standing on your toes using the affected foot.
Balance problems: Reduced stability when standing or walking.
Some people initially notice discomfort only after physical activity. As the condition progresses, pain may occur during shorter periods of walking or standing.
A visible change in foot shape, increasing pain, or difficulty performing a single-leg heel raise should be assessed by a healthcare professional.
7 Helpful Tips for Managing Posterior Tibial Tendon Dysfunction
The following strategies may help manage symptoms and support foot function. The appropriate treatment depends on the condition’s severity and your individual assessment.
1. Choose Supportive Footwear
Footwear plays an important role in supporting your foot during everyday activities.
Shoes that provide insufficient support may increase discomfort when the posterior tibial tendon is already irritated.
Consider footwear that offers:
A stable and supportive sole.
Adequate cushioning.
Comfortable arch support.
A secure heel fit.
Sufficient space for your toes.
Sturdy walking shoes or trainers may be more comfortable than very flexible or unsupportive footwear.
Avoid shoes that consistently increase your inner ankle or arch pain.
If you are unsure which footwear is suitable, a podiatrist or qualified healthcare professional can assess your foot structure and recommend appropriate options.
2. Reduce Activities That Increase Inner Ankle Pain
Repeatedly loading an irritated tendon may increase discomfort and make everyday activities more difficult.
If prolonged walking, running, or standing aggravates your symptoms, temporarily adjusting your activity level may help.
Consider the following:
Reduce walking distances when pain increases.
Avoid prolonged standing where possible.
Temporarily modify high-impact exercise.
Take breaks during demanding activities.
Avoid pushing through worsening pain.
You do not necessarily need to stop all physical activity. Lower-impact activities, such as swimming or comfortable cycling, may be suitable alternatives if they do not aggravate your symptoms.
The goal is to manage tendon loading while maintaining an appropriate level of activity.
3. Consider Suitable Arch Supports or Orthotics
The posterior tibial tendon helps support the arch of your foot. When its function is affected, additional support may help reduce discomfort during walking.
A healthcare professional may recommend:
Over-the-counter arch supports.
Custom-made orthotic devices.
Supportive shoe inserts.
An ankle brace.
A more supportive foot and ankle orthosis in selected cases.
The appropriate support depends on your foot structure, symptoms, and the severity of the condition.
Orthotics may help improve comfort and provide additional support, but they do not necessarily reverse an established foot deformity.
Avoid purchasing expensive custom devices without an appropriate assessment. A podiatrist or foot and ankle specialist can help determine whether they are necessary.
4. Manage Pain and Swelling
If the inside of your ankle becomes painful or swollen after activity, reducing the load may help manage your symptoms.
You may consider:
Resting from activities that increase pain.
Elevating your foot when comfortable.
Applying a wrapped cold pack for short periods.
Wearing supportive footwear.
Avoiding unnecessary pressure around the affected tendon.
If using a cold pack, wrap it in a towel and apply it for up to 20 minutes. Never place ice directly against your skin.
Some people may require temporary ankle support or a walking boot, depending on the severity of the condition. These should only be used following appropriate professional advice.
If swelling is significant or you are having difficulty bearing weight, seek medical assessment.
5. Maintain Comfortable Foot and Ankle Movement
Maintaining suitable movement may help you continue everyday activities while managing symptoms.
However, exercises should be selected carefully because excessive loading may aggravate the affected tendon.
Depending on your assessment, a rehabilitation programme may include:
Gentle ankle mobility exercises.
Comfortable foot movements.
Calf flexibility exercises.
Controlled foot and ankle strengthening.
Gradual balance activities.
Avoid forcing your foot into painful positions or performing demanding exercises without guidance.
If your symptoms increase during or after an exercise, reduce the intensity and seek advice about whether the movement is appropriate.
6. Consider Individualised Physiotherapy
Physiotherapy may play an important role in managing early-stage posterior tibial tendon dysfunction.
An assessment may examine:
Foot arch structure.
Ankle and foot movement.
Posterior tibial tendon tenderness.
Calf flexibility.
Foot and ankle strength.
Walking pattern and balance.
Your ability to perform a heel raise.
Based on the findings, your physiotherapist may recommend:
Progressive foot and ankle strengthening.
Appropriate calf stretching.
Balance and stability exercises.
Advice on modifying daily activities.
Guidance on footwear and support.
A gradual return-to-activity programme.
For example, someone experiencing inner ankle pain during longer walks may benefit from adjusting their walking distance and following a suitable strengthening programme.
Exercise rehabilitation should be progressed according to symptoms and physical capacity. More advanced deformity or significant tendon damage may require specialist assessment.
At PAX Physiotherapy in Modbury North, you can enquire about available physiotherapy and exercise rehabilitation services to discuss whether an assessment may be suitable for your foot and ankle concerns.
7. Seek Early Assessment if Your Foot Shape Changes
Posterior tibial tendon dysfunction can sometimes lead to progressive flattening of the foot arch.
Early assessment is particularly important if you notice changes in your foot shape or increasing difficulty walking.
Arrange an assessment if:
Pain continues along the inside of your ankle.
Swelling develops around the tendon.
Your foot arch appears flatter than before.
You have difficulty standing on your toes.
Walking becomes increasingly uncomfortable.
Your ankle feels weak or unstable.
Seek prompt medical advice if you experience sudden severe pain, significant swelling, or an inability to bear weight.
Do not assume that a changing foot shape is simply a normal consequence of ageing. A healthcare professional can assess the condition and recommend suitable management.
How Is Posterior Tibial Tendon Dysfunction Diagnosed?
Diagnosis usually begins with a discussion about your symptoms, medical history, previous injuries, and daily activities.
A physical examination may include:
Checking the shape of your foot arch.
Assessing tenderness along the tendon.
Examining ankle and foot movement.
Testing muscle strength.
Observing your walking pattern.
Assessing your ability to perform a single-leg heel raise.
A single-leg heel raise can provide useful information about posterior tibial tendon function. However, it is not sufficient on its own to confirm a diagnosis.
Imaging may be recommended when the clinician needs more information about the tendon or foot structure.
Possible investigations include:
Ultrasound: May help assess tendon structure and identify certain tendon abnormalities.
MRI: Can provide detailed information about the tendon and surrounding soft tissues.
X-ray: May be used to examine bone alignment and changes in foot structure, particularly when the arch has become flatter.
Not everyone requires imaging. The appropriate tests depend on the clinical assessment and severity of symptoms.
How Can Physiotherapy Help With Posterior Tibial Tendon Dysfunction?
Physiotherapy may help improve foot and ankle function, particularly when the condition is identified before significant structural changes develop.
The rehabilitation programme is usually adjusted according to the severity of tendon involvement.
Early Management
The initial focus may include:
Reducing activities that aggravate symptoms.
Maintaining comfortable movement.
Improving footwear and support.
Managing pain and swelling.
Establishing appropriate daily activity levels.
Strength and Mobility Rehabilitation
As symptoms allow, exercises may gradually target:
Posterior tibial muscle strength.
Calf strength.
Foot and ankle control.
Calf flexibility.
Balance and stability.
Functional Rehabilitation
Later stages may focus on improving your ability to:
Walk longer distances.
Stand comfortably.
Climb stairs.
Perform daily activities.
Return to suitable exercise.
Physiotherapy is not guaranteed to reverse established foot deformity. More advanced cases may require additional treatment from a foot and ankle specialist.
Can Posterior Tibial Tendon Dysfunction Improve Without Surgery?
Many people with early-stage posterior tibial tendon dysfunction begin with non-surgical management.
Depending on the condition, treatment may include:
Activity modification.
Supportive footwear.
Arch-supporting orthotics.
Ankle braces when recommended.
Physiotherapy and strengthening exercises.
Temporary immobilisation in selected cases.
If symptoms remain significant or the foot deformity progresses, a specialist may discuss surgical options.
The appropriate treatment depends on the condition’s stage, tendon damage, foot alignment, and impact on everyday activities.
Early assessment may help identify suitable management options before more significant changes develop.
How Long Does Posterior Tibial Tendon Dysfunction Take to Improve?
Recovery varies depending on the severity of the condition, how long symptoms have been present, and whether there are structural changes in the foot.
Some people with early-stage symptoms improve with activity modification, appropriate support, and rehabilitation. Others may need a longer treatment period.
Factors that may influence recovery include:
The extent of tendon damage.
Changes in foot arch structure.
Previous ankle injuries.
Daily walking and standing requirements.
Consistency with rehabilitation.
Response to footwear or orthotic support.
More advanced conditions may require specialist treatment and a longer recovery period.
If symptoms are not improving or your foot shape continues to change, seek reassessment.
Frequently Asked Questions About Posterior Tibial Tendon Dysfunction
1. What are the first signs of posterior tibial tendon dysfunction?
Early symptoms commonly include pain or swelling along the inside of the ankle and discomfort around the foot arch. Some people notice pain after walking or standing for extended periods.
2. Can posterior tibial tendon dysfunction cause flat feet?
Yes. When the tendon loses its ability to support the foot arch, the arch may gradually flatten. This can change foot alignment and affect walking.
3. Is walking good for posterior tibial tendon dysfunction?
Walking may remain possible, particularly in early cases, but prolonged walking can aggravate symptoms. Adjust your walking distance according to your comfort and follow professional advice about suitable activity levels.
4. Can physiotherapy help with posterior tibial tendon dysfunction?
Physiotherapy may help improve foot and ankle strength, movement, balance, and walking ability. A suitable rehabilitation programme may include progressive strengthening and mobility exercises.
5. Do I need orthotics for posterior tibial tendon dysfunction?
Some people benefit from arch-supporting insoles or custom orthotics. However, the right type of support depends on foot structure and symptom severity. A qualified healthcare professional can assess whether orthotics are appropriate.
6. Does posterior tibial tendon dysfunction require surgery?
Not always. Many early cases are initially managed with supportive footwear, orthotics, activity modification, and physiotherapy. Surgery may be considered when symptoms are severe, structural changes progress, or non-surgical treatment is unsuccessful.
7. When should I see a doctor for inner ankle pain?
Seek medical advice if inner ankle pain persists, swelling develops, your foot arch changes, or you have difficulty standing on your toes. Early assessment is important when symptoms are progressing.
