Peroneal tendon tear: Cause, Symptoms, Treatment, Exercise

What is a Peroneal tendon tear?

Peroneal tendon tear

Peroneal tendon tear is a condition where one or both tendons that run down the outer side of the lower leg, behind the ankle and into the foot, are partially or completely torn. These tendons are responsible for stabilizing the ankle and foot during movement, especially during activities that involve twisting or turning of the foot. 

A tear in the peroneal tendons can lead to pain, weakness, swelling, and instability in the ankle and foot. It can be caused by repetitive strain, overuse, or traumatic injury to the tendons. Treatment for peroneal tendon tear may involve rest, immobilization, physical therapy, or surgery depending on the severity of the injury.

Related Anatomy

The peroneal tendons are two fibrous cords that originate from the muscles in the outer part of the lower leg, the peroneus longus, and peroneus brevis muscles. The peroneus longus tendon runs under the foot and attaches to the first metatarsal bone, while the peroneus brevis tendon runs behind the ankle and attaches to the fifth metatarsal bone. 

These tendons work together to stabilize the ankle and foot during movement, especially during activities that involve twisting or turning of the foot. The tendons are surrounded by a protective sheath and held in place by ligaments and other soft tissues. The blood supply to the peroneal tendons is limited, which can make them susceptible to injury and slow to heal.

Causes of Peroneal tendon tear

Peroneal tendon tears can be caused by a variety of factors, including:

• Repetitive Strain: Activities that involve repetitive motions, such as running, jumping, and dancing, can put a strain on the peroneal tendons and lead to small tears over time.
• Ankle Sprains: A severe ankle sprain or twisting injury can cause a peroneal tendon tear.
• Overuse: Overuse of the peroneal tendons without adequate rest and recovery can lead to tendon damage and eventually tears.
• Degeneration: Aging and wear and tear can lead to degeneration of the peroneal tendons, making them more prone to injury.
• Abnormal Foot Mechanics: Certain foot deformities, such as flat feet or high arches, can place extra stress on the peroneal tendons and increase the risk of tears.
• Trauma: Direct trauma to the ankle or lower leg, such as a fall or impact injury, can cause a peroneal tendon tear.
• Improper Footwear: Wearing shoes that do not fit properly or provide adequate support can increase the risk of peroneal tendon injuries.

Symptoms of Peroneal tendon tear

The symptoms of a peroneal tendon tear can vary depending on the severity of the injury. Common symptoms include:

• Pain: The most common symptom of a peroneal tendon tear is pain on the outside of the ankle and foot, especially when bearing weight or moving the foot.
• Swelling: The affected area may be swollen and tender to the touch.
• Weakness: A peroneal tendon tear can cause weakness in the ankle and foot, making it difficult to move the foot or maintain balance.
• Instability: The ankle may feel unstable or give way, especially when walking on uneven surfaces.
• Clicking or popping: A popping or clicking sound may be heard or felt when moving the ankle or foot.
• Redness or warmth: The skin around the affected area may be red or warm to the touch.
• Limited range of motion: A peroneal tendon tear can limit the range of motion of the ankle and foot, making it difficult to perform activities such as walking, running, or jumping.

It is important to seek medical attention if you experience any of these symptoms, as untreated peroneal tendon tears can lead to chronic ankle instability and other complications.

Risk Factor

Several risk factors may increase the likelihood of developing a peroneal tendon tear, including:

• Age: Tendon degeneration and wear and tear increases with age, making older individuals more susceptible to tendon injuries.
• Overuse: Repetitive activities that place stress on the peroneal tendons, such as running or jumping, increase the risk of developing a tear.
• Improper Footwear: Wearing shoes that do not fit properly or provide adequate support can increase the risk of developing a peroneal tendon tear.
• Foot Deformities: Certain foot deformities, such as flat feet or high arches, can put extra stress on the peroneal tendons and increase the risk of developing a tear.
• Trauma: A traumatic injury, such as a fall or ankle sprain, can cause a peroneal tendon tear.
• Sports Participation: Participation in sports that involve twisting or turning of the foot, such as soccer or basketball, can increase the risk of developing a peroneal tendon tear.
• Weakness or Tightness in Muscles: Weakness or tightness in the muscles surrounding the ankle and foot can affect the alignment of the foot, putting additional stress on the peroneal tendons.

It is important to be aware of these risk factors and take steps to prevent peroneal tendon tears, such as wearing appropriate footwear, using proper technique during physical activity, and maintaining strong and flexible muscles in the lower leg and foot.

Differential Diagnosis

The symptoms of a peroneal tendon tear can be similar to those of other conditions affecting the ankle and foot. Therefore, it is important to consider other possible diagnoses when evaluating a patient with these symptoms. Some of the differential diagnoses that may need to be ruled out include:

• Ankle sprain: An ankle sprain is a common injury that can cause pain, swelling, and instability in the ankle. It occurs when the ligaments that support the ankle joint are stretched or torn.
• Achilles tendonitis: Achilles tendonitis is an overuse injury that affects the Achilles tendon, which connects the calf muscles to the heel bone. It can cause pain, swelling, and stiffness in the back of the ankle and lower leg.
• Stress fracture: A stress fracture is a small crack in a bone that can occur due to overuse or repetitive stress. It can cause pain, swelling, and tenderness in the affected area.
• Plantar fasciitis: Plantar fasciitis is a condition that affects the plantar fascia, a thick band of tissue that runs along the bottom of the foot. It can cause heel pain, especially in the morning or after prolonged periods of standing or walking.
• Tarsal tunnel syndrome: Tarsal tunnel syndrome is a condition that occurs when the posterior tibial nerve, which runs through a narrow passage in the ankle, becomes compressed. It can cause pain, numbness, and tingling in the ankle and foot.
• Arthritis: Arthritis is a condition that causes inflammation in the joints, which can lead to pain, swelling, and stiffness. It can affect any joint in the body, including the ankle and foot.

It is important to consult a healthcare professional for an accurate diagnosis, as treatment can vary depending on the underlying cause of the symptoms.

Diagnosis

The diagnosis of a peroneal tendon tear typically begins with a physical examination by a healthcare professional. During the examination, the healthcare professional will look for signs of swelling, tenderness, instability, and weakness in the ankle and foot. They may also ask about the patient's medical history, including any previous injuries or conditions that may affect the ankle or foot.

If a peroneal tendon tear is suspected, imaging tests may be ordered to confirm the diagnosis and determine the severity of the injury. Common imaging tests used to diagnose a peroneal tendon tear include:

• X-ray: An X-ray may be ordered to rule out the possibility of a bone fracture or other bony abnormalities.
• Magnetic resonance imaging (MRI): An MRI uses a magnetic field and radio waves to produce detailed images of the soft tissues in the ankle and foot, including the peroneal tendons. It can help to identify the location and severity of a peroneal tendon tear.
• Ultrasound: An ultrasound uses high-frequency sound waves to produce images of the soft tissues in the ankle and foot, including the peroneal tendons. It can help to identify the presence and location of a tear.

Once a diagnosis is confirmed, the healthcare professional will develop a treatment plan based on the severity of the injury and the patient's individual needs and goals. Treatment may include rest, ice, compression, elevation, physical therapy, and in some cases, surgery.

Peroneal tendon tear Test

There are several tests that can be performed to help diagnose a peroneal tendon tear. These tests are usually performed by a healthcare professional, such as a doctor or physical therapist. Some common tests include:

• Palpation: The healthcare professional may gently press and feel along the path of the peroneal tendons to check for tenderness or swelling.
• Range of motion: The healthcare professional may check the range of motion of the ankle and foot, looking for any limitations or pain during movement.
• Resistance tests: The healthcare professional may apply resistance to the ankle and foot to check for weakness or pain.
• Functional tests: The healthcare professional may ask the patient to perform specific movements, such as standing on the affected foot or walking on their toes or heels, to assess function and stability.
• Imaging tests: Imaging tests, such as X-rays or MRI, may be ordered to provide more detailed information about the extent of the injury.

It is important to seek prompt medical attention if you suspect a peroneal tendon tear, as an accurate diagnosis is key to developing an effective treatment plan.

Treatment of Peroneal tendon tear

The treatment for a peroneal tendon tear will depend on the severity of the injury. In general, treatment options may include:

• Rest and immobilization: The first step in treating a peroneal tendon tear is to rest and protect the affected foot and ankle. A healthcare professional may recommend immobilization with a cast, brace, or walking boot to limit movement and allow the tendon to heal.
• Ice and compression: Applying ice and compression to the affected area can help to reduce swelling, inflammation, and pain.
• Physical therapy: Physical therapy exercises can help to strengthen the muscles and improve the range of motion in the ankle and foot. This may involve stretching, range of motion exercises, and strengthening exercises.
• Medications: Over-the-counter pain medications, such as acetaminophen or ibuprofen, may be recommended to help manage pain and inflammation.
• Corticosteroid injections: In some cases, a healthcare professional may recommend a corticosteroid injection to help reduce inflammation and pain.
• Surgery: If the tear is severe or does not respond to non-surgical treatments, surgery may be necessary. Surgery may involve repairing the torn tendon or, in some cases, transferring a nearby tendon to replace the damaged peroneal tendon.
• Orthotics: Wearing a supportive brace or custom orthotics can help to provide additional support and prevent further injury.

It is important to follow a healthcare professional's recommendations for treatment and allow sufficient time for the tendon to heal before returning to physical activity. With proper treatment and rehabilitation, most people with a peroneal tendon tear can return to their normal activities.

Can Peroneal tendon tear heal without surgery?

In many cases, a peroneal tendon tear can heal without surgery, particularly if it is a partial tear or if the tear is detected and treated early. However, the specific treatment plan will depend on the severity and extent of the tear, as well as other factors such as the patient's age, overall health, and activity level.

Conservative treatment options for a peroneal tendon tear may include rest, ice, compression, elevation, and physical therapy to help improve strength, flexibility, and range of motion. In some cases, a brace or cast may be recommended to immobilize the ankle and foot and allow the tendon to heal.

Surgery may be necessary for more severe or complex peroneal tendon tears, such as complete tears or tears that involve multiple tendons. Surgery may also be recommended if conservative treatments have not been effective in improving symptoms or if the tear is causing significant instability or dysfunction of the ankle and foot.

It is important to work closely with a healthcare professional to determine the most appropriate treatment plan for a peroneal tendon tear. Delaying treatment or failing to properly address the injury can increase the risk of complications and long-term problems.

Is Peroneal tendon surgery worth it?

Whether or not peroneal tendon surgery is worth it depends on several factors, including the severity of the injury, the patient's overall health and activity level, and the potential risks and benefits of the surgery.

In some cases, surgery may be necessary to repair a complete or complex peroneal tendon tear or to address other structural problems in the ankle or foot that are contributing to the injury. Surgery may also be recommended if conservative treatments have not been effective in improving symptoms or if the tear is causing significant instability or dysfunction of the ankle and foot.

However, surgery also carries risks, including the potential for infection, nerve damage, or other complications. Recovery from surgery can also be a lengthy process, and may require a period of immobilization, physical therapy, and activity restrictions.

Ultimately, the decision to undergo peroneal tendon surgery should be made in consultation with a healthcare professional, who can help weigh the potential risks and benefits of the procedure and determine the most appropriate treatment plan based on the individual patient's needs and circumstances.

Can a peroneal tendon tear heal on its own?

In some cases, a peroneal tendon tear can heal on its own, particularly if it is a partial tear or if the tear is detected and treated early. However, the specific treatment plan will depend on the severity and extent of the tear, as well as other factors such as the patient's age, overall health, and activity level.

Conservative treatment options for a peroneal tendon tear may include rest, ice, compression, elevation, and physical therapy to help improve strength, flexibility, and range of motion. In some cases, a brace or cast may be recommended to immobilize the ankle and foot and allow the tendon to heal.

However, complete tears of the peroneal tendon or more severe injuries may not heal on their own and may require surgical intervention to repair the tendon.

It is important to work closely with a healthcare professional to determine the most appropriate treatment plan for a peroneal tendon tear. Delaying treatment or failing to properly address the injury can increase the risk of complications and long-term problems.

How long does it take to heal a torn peroneal tendon?

The length of time it takes to heal a torn peroneal tendon can vary depending on the severity and extent of the tear, as well as the specific treatment approach used. In general, it can take several weeks to several months to fully heal a torn peroneal tendon.

For minor or partial tears, conservative treatment options such as rest, ice, compression, and physical therapy may be effective in promoting healing and reducing symptoms. With these treatments, patients may begin to see improvement in their symptoms within a few weeks and may be able to gradually return to their normal activities over the course of several months.

For more severe or complete tears, surgery may be necessary to repair the tendon. Following surgery, patients may need to wear a cast or brace for several weeks to allow the tendon to heal. Physical therapy and rehabilitation exercises will also be necessary to help rebuild strength and restore range of motion.

It is important for patients to follow their healthcare professional's recommended treatment plan and allow for sufficient healing time to avoid reinjury or other complications.
