Healing time of high ankle sprains

Diagnosing a high ankle sprain

Accurate diagnosis is essential, as high ankle sprains can be more severe than low ankle sprains. A physical examination often includes the Kleiger’s test, where the ankle is rotated outward to assess pain levels, and the syndesmosis squeeze test, which applies pressure to the lower leg bones to check for ligament damage. Imaging scans such as X-rays, MRI, or CT scans help rule out fractures and provide a clearer picture of ligament injuries. Early diagnosis ensures appropriate treatment and prevents complications.

High vs low ankle sprains

Ankle sprains vary in severity and location. Low ankle sprains are more common and occur when the foot rolls inward or outward, stretching or tearing the ligaments on the outer or inner side of the ankle. These injuries often result from sudden twisting motions and are frequently seen in everyday activities. High ankle sprains, however, involve the ligaments that connect the tibia and fibula above the ankle joint. They typically occur from high-impact movements or excessive twisting while the foot is planted, making them more common in athletes.

What does the treatment look like?

Most high ankle sprains are managed conservatively using the RICE method (rest, ice, compression, elevation) to reduce swelling and promote healing. Immobilisation with a walking boot or brace helps stabilise the joint, while physical therapy focuses on regaining strength and mobility. Severe cases, where the ligaments are significantly torn, may require surgery to stabilise the bones and restore ankle function. Proper rehabilitation is crucial in preventing long-term weakness and ensuring a full recovery.

How long does it take to recover from a high ankle sprain?

Factors influencing recovery time

Several factors can impact how quickly a high ankle sprain heals:

• Severity of the sprain – More extensive ligament damage requires a longer healing process.

• Treatment approach – Immobilisation, physical therapy, and rest significantly affect recovery speed.

• Adherence to rehabilitation – Following a structured recovery plan improves outcomes.

• Age and fitness level – Younger individuals and those in good physical condition tend to recover faster.

• Pre-existing conditions – Weak ankle stability or prior injuries can delay healing.

How does recovery differ by sprain severity?

The severity of a high ankle sprain is classified into three grades, each with a different recovery timeline:

• Grade 1 (Mild Sprain) – Minimal ligament stretching, no significant tearing. Recovery takes around 6-8 weeks with rest, ice, compression, elevation (RICE), and gradual rehabilitation.

• Grade 2 (Moderate Sprain) – Partial ligament tearing, leading to noticeable swelling and pain. Recovery usually requires 8-12 weeks and may involve using a walking boot or brace for stability.

• Grade 3 (Severe Sprain) – Complete ligament rupture, often requiring surgery. Recovery can take 3-6 months, depending on the success of surgery and rehabilitation.

Can rehabilitation speed up the healing process?

Rehabilitation is essential in restoring strength, flexibility, and stability after a high ankle sprain. Once the initial inflammation subsides, physical therapy focuses on improving mobility, strengthening the ankle, and gradually reintroducing weight-bearing activities. Balance exercises help prevent re-injury, while controlled strength training supports long-term stability. Skipping or rushing rehabilitation can lead to lingering pain or instability, prolonging the recovery process.

When is surgery required, and how does it affect recovery?

Surgery is usually necessary for severe high ankle sprains involving complete ligament rupture or fractures. The procedure stabilises the joint with screws or a tightrope technique, holding the tibia and fibula together while the ligaments heal. Post-surgical recovery is longer, often requiring 6-12 weeks of non-weight-bearing movement followed by progressive rehabilitation. Returning to sports or high-impact activities may take six months or longer, depending on individual progress.

How can you prevent re-injury during recovery?

Returning to normal activities too soon can increase the risk of re-injury. Proper ankle support, such as braces or taping, helps stabilise the joint, while gradually increasing activity levels reduces the strain on healing ligaments. Strength and balance exercises should continue even after symptoms improve to prevent future instability. Consulting a healthcare professional before resuming high-impact activities ensures a safe and steady recovery.
