Key Takeaways
- A high ankle sprain affects the ligaments that connect the tibia and fibula above the ankle joint rather than the outer ankle ligaments.
- Symptoms often include pain higher up in the ankle region, especially during twisting or weight-bearing movements.
- This type of injury is commonly caused by rotational forces that place stress on the syndesmotic ligaments connecting the lower leg bones.
- Recovery may take longer because the injured structures are involved in stabilising the lower leg during everyday activities such as walking.
Why Does a High Ankle Sprain Take Longer to Heal?
Ankle sprains are common injuries, but not all sprains affect the same structures or follow the same recovery timeline. A high ankle sprain involves the ligaments that connect the tibia and fibula above the ankle joint, rather than the ligaments on the outside of the ankle that are more commonly injured.
Because these ligaments help maintain the relationship between the lower leg bones during movement, injuries in this area can affect walking, turning, and weight-bearing activities. Understanding how the injury occurs and why recovery may differ from other ankle sprains can help set realistic expectations during the healing process.
What Is a High Ankle Sprain?
A high ankle sprain affects the syndesmosis, the group of ligaments located above the ankle joint that helps hold the tibia and fibula together.
These ligaments help maintain stability between the lower leg bones during walking, running, and changes in direction. Unlike a typical ankle sprain, which usually affects the ligaments on the outer side of the ankle, a syndesmosis injury affects the structures located between the tibia and fibula.
Because these ligaments contribute to the stability of the ankle and lower leg, an injury in this area can affect how the ankle moves and bears weight during everyday activities.
How Does the Injury Occur?
This type of injury usually occurs when a twisting or rotational force is applied to the ankle while the foot is firmly planted on the ground.
This movement can place stress on the ligaments that connect the tibia and fibula. In more severe cases, it may result in abnormal widening or movement between the two bones, affecting the stability of the ankle. Such injuries are commonly associated with activities that involve sudden changes in direction, pivoting, jumping, or contact with another player or object.
Unlike a typical ankle sprain, which often occurs when the foot rolls inward, a high ankle sprain is more commonly linked to rotational forces acting through the ankle and lower leg. Because swelling may be less obvious than expected, the injury is sometimes mistaken for a less serious ankle sprain during the early stages.
Why Does the Pain Feel Different?
One feature that often distinguishes this injury from other ankle injuries is the location of the pain.
Many people experience ankle pain above the ankle joint level, often between the tibia and fibula rather than around the outer side of the ankle. The discomfort may become more noticeable during activities that place rotational stress on the ankle, such as turning, pushing off while walking, climbing stairs, or changing direction.
The pain is not always present at rest. In some cases, symptoms are only triggered by certain movements or weight-bearing activities, which can make the injury seem less serious than it actually is during the early stages.
Why Recovery Often Takes Longer
Everyday Movement Continues to Place Stress on the Injury
Recovery from the injury can be slower for several reasons. One factor is that the injured area is involved in many everyday activities, including walking and weight-bearing movements. Depending on the severity of the injury, activity modification, bracing, or temporary restrictions may be recommended to reduce stress on the healing ligaments.
Even with appropriate protection, gradual loading is often required as recovery progresses, which can make rehabilitation more complex than some other ankle injuries.
Stability Must Also Be Restored
Recovery is influenced not only by ligament healing but also by the overall stability of the ankle and lower leg.
In some cases, the injury remains stable and responds well to non-surgical management, which may include activity modification, bracing, or rehabilitation. In others, there may be widening between the tibia and fibula, associated fractures, or more extensive ligament damage.
This is one reason why the recovery time for a high ankle sprain varies considerably between individuals and may be longer than recovery from a typical ankle sprain.
Common Symptoms to Look Out For
Symptoms can vary depending on the severity of the condition and the structures involved.
These may include:
- Pain above the ankle joint
- Discomfort that worsens during twisting or turning movements
- Pain when walking, running, or bearing weight
- Tenderness between the tibia and fibula
- Swelling around the ankle or lower leg
- A feeling of instability or weakness
- Difficulty walking confidently on uneven surfaces
One characteristic of the injury is that swelling may not always be as noticeable as people expect. As a result, the injury can sometimes appear less serious than it actually is, even when the ligaments involved have been significantly affected.
How Is the Injury Assessed?
Clinical Examination
Assessment typically begins with a clinical examination and a discussion of how the injury occurred and the symptoms experienced since then.
The doctor will assess the location of the pain, evaluate ankle stability, and perform specific movements designed to place controlled stress on the syndesmosis. Tests involving rotation or compression of the lower leg may help determine whether the ligaments connecting the tibia and fibula have been affected.
Individuals experiencing ongoing symptoms after an ankle injury may consider seeking assessment at an orthopaedic clinic to determine whether the syndesmosis or other structures are involved.
Imaging Studies
Imaging may be recommended if further evaluation is needed.
X-rays can help assess the alignment of the tibia and fibula and identify any widening between the bones or associated fractures. They may also help distinguish the injury from a broken ankle or other injuries that can cause similar symptoms.
In some cases, an MRI scan may be used to provide a more detailed view of the ligaments and surrounding soft tissues.
The information gathered from imaging helps clinicians assess the severity of the injury, determine whether the ankle remains stable, and identify any associated damage that may influence treatment and recovery.
What Affects Recovery Time?
Recovery from the injury can vary significantly from person to person.
Factors that may influence recovery include:
- The severity of the injury
- Whether the ankle remains stable after the injury
- The individual’s activity demands
- Response to treatment and rehabilitation
- The presence of any associated injuries
Recovery often involves a gradual return to activity, with progression based on symptoms, functional improvement, and overall ankle stability.
When Should You Seek Medical Attention?
Medical assessment is generally recommended if:
- You are unable to bear weight comfortably after the injury
- Pain or swelling continues to worsen rather than improve
- The ankle feels unstable during walking
- Symptoms persist despite rest and activity modification
- You have difficulty returning to work, exercise, or sports
- The injury does not seem to be progressing as expected
Because the injury can sometimes be mistaken for more common ankle injuries, persistent or worsening symptoms may warrant further evaluation. If symptoms continue to interfere with daily activities, consultation with an ankle specialist may help clarify the cause and guide appropriate management.
Understanding Why the Injury Requires Careful Assessment
High ankle sprains can sometimes be more complex than they initially appear. Symptoms may not always reflect the severity of the injury, and recovery can vary depending on factors such as ligament damage, ankle stability, and the presence of associated injuries.
Recognising when symptoms are not improving as expected and seeking appropriate assessment can help identify the structures involved and guide the next steps for recovery.
If you are experiencing persistent pain above the ankle or difficulty returning to normal activities after an injury, consider consulting Specialist Orthopaedic Centre. A thorough evaluation can help clarify the cause of your symptoms and determine the most appropriate next steps for recovery.
