Causes of Achilles Tendon Rupture

Achilles tendon rupture is a common injury that occurs when the Achilles tendon, the largest tendon in the body, tears or breaks apart. Understanding the causes of this condition is essential in preventing and managing it effectively.

Overuse and Repetitive Stress

One of the primary causes of Achilles tendon rupture is overuse and repetitive stress on the tendon. This often occurs in athletes or individuals who engage in activities that involve frequent jumping or running. The constant strain placed on the tendon can weaken it over time, making it more prone to rupture.

Trauma or Sudden Force

Another common cause of Achilles tendon rupture is trauma or sudden force applied to the tendon. This can happen during a fall, landing from a jump, or a direct impact to the back of the leg. The sudden and excessive force placed on the tendon can lead to its rupture.

Achilles Tendonitis

Achilles tendonitis, which refers to inflammation of the Achilles tendon, is also a contributing factor to tendon rupture. When the tendon becomes inflamed, it weakens and becomes more susceptible to tearing or breaking. Chronic inflammation and improper treatment of Achilles tendonitis can increase the risk of rupture.

Certain Medications

In some cases, the use of certain medications can increase the risk of Achilles tendon rupture. Fluoroquinolone antibiotics, commonly prescribed for infections, have been associated with an increased risk of tendon rupture. These medications can weaken the tendon structure, making it more prone to injury.

Medical Conditions

Certain medical conditions can also contribute to the development of Achilles tendon rupture. Conditions such as gout, rheumatoid arthritis, and systemic lupus erythematosus can weaken the tendon and increase the risk of rupture. It is important to manage these underlying conditions to reduce the risk of tendon injuries.

Risk Factors for Achilles Tendon Rupture

While anyone can experience an Achilles tendon rupture, certain factors can increase an individual’s susceptibility to this injury. Understanding these risk factors can help individuals take preventive measures and seek appropriate care.


The risk of Achilles tendon rupture increases with age. Middle-aged and older individuals are more prone to this injury due to the natural aging process, which leads to the degeneration and weakening of the tendon.


Men are more likely to experience Achilles tendon rupture compared to women. This difference may be attributed to the fact that men generally have larger and stronger calf muscles, which can place more stress on the tendon.


Excess weight and obesity can put additional strain on the Achilles tendon, increasing the risk of rupture. Maintaining a healthy weight can help reduce the stress on the tendon and lower the risk of injury.

Weak Calf Muscles

Weak calf muscles can contribute to the development of Achilles tendon rupture. The calf muscles play a crucial role in supporting the Achilles tendon, and if they are weak or imbalanced, the tendon may be subjected to excessive stress.

Steroid Injections

The use of corticosteroid injections for the treatment of conditions such as tendonitis can weaken the tendon and increase the risk of rupture. These injections should be used with caution and under the guidance of a healthcare professional.

Poor Footwear Choices

Wearing inappropriate footwear, such as shoes with inadequate support or high heels, can increase the risk of Achilles tendon rupture. Proper footwear with good arch support and cushioning can help protect the tendon and reduce the likelihood of injury.

Signs and Symptoms of Achilles Tendon Rupture

Recognizing the signs and symptoms of Achilles tendon rupture is crucial for prompt diagnosis and appropriate treatment. If you suspect that you have ruptured your Achilles tendon, it is important to seek medical attention immediately.

Sudden and Severe Pain

One of the most prominent symptoms of Achilles tendon rupture is sudden and severe pain. You may experience an intense shooting or stabbing pain at the back of your leg, near the heel. The pain is often described as being sharp and immediate.

A Snapping or Popping Sound

Many individuals report hearing a snapping or popping sound at the time of Achilles tendon rupture. This audible sign is often accompanied by a sudden onset of pain. If you notice this sound while engaging in physical activity, it is important to seek medical evaluation.

Swelling and Bruising

Following an Achilles tendon rupture, swelling and bruising are common symptoms. The affected area may become visibly swollen, and bruising may develop around the ankle and heel. These signs indicate the presence of internal bleeding and inflammation.

Difficulty Walking or Pointing Toes Downward

Achilles tendon rupture can severely impair the ability to walk and perform certain movements. You may find it challenging to bear weight on the affected leg or point your toes downward. This difficulty is due to the disruption of the Achilles tendon’s function.

Diagnosis of Achilles Tendon Rupture

To diagnose an Achilles tendon rupture accurately, a healthcare professional will conduct a thorough examination and may order imaging tests. Prompt and accurate diagnosis is crucial for determining the appropriate treatment approach.

Physical Examination

During the physical examination, the healthcare professional will assess the affected leg and ankle. They will look for signs of swelling, bruising, and an obvious gap or deformity in the Achilles tendon. They may also ask you to perform certain movements to gauge your range of motion and assess the strength of your calf muscles.

Palpation and Gap Test

Palpation involves feeling the area around the Achilles tendon to identify any defects or gaps. A positive palpation test, where a gap can be felt in the tendon, indicates a possible rupture. Another test called the gap test involves squeezing the calf muscle while assessing the range of motion. A gap or lack of movement suggests a tendon rupture.

Imaging Tests (MRI, Ultrasound)

Imaging tests, such as MRI or ultrasound, are often used to confirm the diagnosis of Achilles tendon rupture and assess its severity. These tests provide detailed images of the tendon, allowing the healthcare professional to evaluate the extent of the tear and plan appropriate treatment.

Thompson Test

The Thompson test is a simple and reliable test used to diagnose Achilles tendon rupture. During this test, you will be asked to lie face down on the examination table with your feet hanging off the edge. The healthcare professional will gently squeeze your calf muscle, and if there is no movement in your foot, it indicates a rupture.

Non-Surgical Treatment Options

In some cases, non-surgical treatment may be appropriate for the management of Achilles tendon rupture. This approach is typically considered for individuals who have a partial tear or those who may not be suitable candidates for surgery due to certain factors.

Rest, Ice, Compression, and Elevation (RICE)

Rest is essential in promoting the natural healing process of the tendon. Applying ice packs to the affected area can help reduce pain and swelling. Compression with an elastic bandage can provide support and minimize further damage. Elevating the leg can also help decrease swelling.

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

Nonsteroidal anti-inflammatory drugs, such as ibuprofen or naproxen, can help manage pain and reduce inflammation. These medications should be taken as directed and under the guidance of a healthcare professional.

Physical Therapy and Stretching Exercises

Physical therapy plays a crucial role in the non-surgical treatment of Achilles tendon rupture. A physical therapist will guide you through specific exercises to strengthen the calf muscles and improve flexibility. These exercises help promote healing and prevent future injuries.

Orthotic Devices

Orthotic devices, such as heel lifts or custom orthotic inserts, can provide support and reduce stress on the Achilles tendon. These devices are designed to correct any biomechanical abnormalities and help optimize the healing process.

Extracorporeal Shock Wave Therapy (ESWT)

Extracorporeal shock wave therapy is a non-invasive treatment option that uses high-energy sound waves to stimulate healing in the Achilles tendon. This therapy can help promote tissue regeneration and reduce pain.

Surgical Treatment Options

Surgical intervention may be necessary in some cases of Achilles tendon rupture, especially for individuals with complete tears or those who require a faster recovery for optimal functionality.

Open Surgery

Open surgery involves making an incision in the back of the leg to directly access and repair the ruptured tendon. This approach allows the surgeon to reattach the tendon securely and address any additional damage.

Minimally Invasive Surgery

Minimally invasive surgery, also known as percutaneous surgery, is a less invasive alternative to open surgery. Instead of making a large incision, multiple small incisions are made to access and repair the tendon. This approach typically results in a quicker recovery and less scarring.

Tendon Transfer

In cases where the Achilles tendon cannot be repaired, a tendon transfer procedure may be performed. This involves transferring an adjacent tendon to replace the function of the damaged Achilles tendon. The transferred tendon is secured to the heel bone and provides the necessary support and functionality.

Rehabilitation and Post-Operative Care

Following surgical treatment, a comprehensive rehabilitation program is essential for optimal recovery. This typically involves physical therapy exercises, range of motion activities, and gradual weight-bearing exercises. The duration and intensity of rehabilitation will depend on the individual’s specific condition and the surgical approach used.

Complications and Risks

While the treatment of Achilles tendon rupture is generally effective, complications and risks may arise, especially if the condition is not properly managed. It is essential to be aware of these potential complications and take appropriate steps to minimize their occurrence.


Infection is a potential complication of any surgical procedure, including the treatment of Achilles tendon rupture. Proper hygiene, wound care, and adherence to post-operative instructions can help reduce the risk of infection. Prompt medical attention should be sought if any signs of infection, such as increased pain, redness, or swelling, are observed.

Nerve Damage

During surgical treatment, there is a risk of nerve damage around the surgical site. This can lead to altered sensation, weakness, or loss of function in the affected area. Surgeons take precautions to minimize this risk, but it is important to be aware of the possibility and report any unusual symptoms to the healthcare team.


In some cases, the repaired Achilles tendon may experience a rerupture, either due to excessive stress or improper healing. This risk can be minimized by following the recommended rehabilitation protocols and gradually returning to activities under the guidance of a healthcare professional.

Stiffness and Limited Range of Motion

After Achilles tendon rupture and its subsequent treatment, some individuals may experience stiffness and limited range of motion in the ankle joint. Physical therapy, stretching exercises, and gradual mobilization can help improve flexibility and restore normal range of motion.
