Achilles Tendon Injury: Symptoms, Causes, Treatment & Recovery

There exist various types of Achilles tendon injuries characterised by their unique symptoms and causes. Delving deeper, we can explore some of the frequently observed ones.

1. Achilles Tendinitis: When the Achilles tendon is repeatedly stressed or overused, it tends to become inflamed. Characterised by tenderness, stiffness, and discomfort in the backside of the ankle, this condition is often aggravated in the morning or after prolonged sitting.

2. Achilles Tendinosis: The condition bears resemblance to tendinitis, but with a slight variation: rather than inflammation, the tendons undergo a degenerative process, leading to fibre breakdown. Such degradation may cause discomfort, swelling, and debilitation in the ankle region.

3. Achilles Tendon Rupture: When there is sudden stress on the Achilles tendon due to forceful movements such as jumping or pivoting, it may result in a complete tear. The symptoms of this condition include experiencing a popping sound accompanied by sharp pain and facing walking problems.

4. Insertional Achilles Tendinopathy: When the tendon that attaches to the heel bone gets injured, it brings about this condition. Indications of this problem entails discomfort, enlargement, and sensitivity at the rear of the heel.

5. Non-Insertional Achilles Tendinopathy: The condition bears resemblance to tendinosis, however, the affected area of the tendon is situated at a higher position. The manifestation of the ailment includes discomfort and inflexibility in the ankle, notably following physical exertion. 

Here are the symptoms of Achilles Injury:

1. Pain: Discomfort in the posterior part of the ankle or heel is a prevailing indication of an Achilles tendon injury. The severity of this unpleasant sensation may vary from a minor irritation to acute agony and may be persistent or sporadic contingent on specific movements or actions.

2. Swelling: Swelling in the vicinity of the Achilles tendon is also prevalent. This can either be confined to a particular region or stretch up towards the rear of the calf.

3. Stiffness: Stiffness in the ankle joint can be a common aftermath of Achilles tendon injuries, which may impede the smooth movement of the foot and walking pattern.

4. Tenderness: An injury to the Achilles tendon may cause sensitivity in the surrounding area, resulting in discomfort when applying pressure on the ankle or wearing shoes that create friction against the tendon. Experiencing tenderness while touching the affected area is a common symptom.

5. Loss of strength: The ankle and foot may experience a loss of strength in situations where the Achilles tendon injury is more serious. This can result in challenges while performing day-to-day tasks such as standing, walking, or engaging in any other physical activity.

6. Popping sound: At times, when an injury occurs, an abrupt and piercing popping noise might be audible. Subsequently, this is frequently chased by instantaneous discomfort and obstacles in walking. 

Achilles tendon injury can be caused by a variety of factors, including overuse, sudden trauma, degeneration, and certain medical conditions. Here are the common causes of Achilles tendon injury:

1. Overuse: Amongst the causes of Achilles tendon injury is overuse. Repetitive stress and strain on the tendon can cause it to become inflamed, swollen, and painful. This is especially true for individuals who are in high-impact activities.

2. Sudden trauma: A sudden, forceful impact to the tendon can also cause Achilles tendon injury. This can occur during sports, falls, or other types of accidents. In some cases, a complete rupture of the tendon may occur, requiring surgery to repair.

3. Degeneration: As we age, our tendons naturally lose elasticity and strength, making them more prone to injury. This is especially true for the Achilles tendon, which can undergo degradation over time, resulting in weakness, stiffness, and an increased risk of injury.

4. Poor conditioning: Individuals who are not physically active or who have poor conditioning are more susceptible to Achilles tendon injury. Weak muscles, poor flexibility, and poor circulation can contribute to an increased risk of injury.

5. Medical conditions: Certain medical conditions can increase the risk of Achilles tendon injury. These conditions can affect the strength and flexibility of the tendon and make it more prone to injury.

6. Medications: Some medications can weaken the tendon and increase the risk of injury.

Certain factors can increase the risk of Achilles tendon injury, including:

1. Age: The risk of Achilles tendon injury increases with age, as the tendon becomes less flexible and more prone to injury.
2. Gender: Men are more likely to experience Achilles tendon injury than women.
3. Physical Activity: Engaging in high-impact activities such as running, jumping, or dancing can increase the risk of Achilles tendon injury.
4. Medical Conditions: Certain medical conditions such as obesity, diabetes, and arthritis can increase the risk of Achilles tendon injury.
5. Medications: Certain medications such as corticosteroids can weaken the Achilles tendon and increase the risk of injury.

Preventing Achilles tendon injury requires taking a proactive approach to maintain the strength and flexibility of the tendon. Here are some tips to prevent Achilles tendon injury:

1. Warm-Up and Stretch: Before engaging in physical activity, it is essential to warm-up and stretch the muscles and tendons, including the Achilles tendon.

2. Wear Proper Footwear: Wear well-fitting shoes that provide proper support and comfort for the feet and ankles.

3. Gradual Increase in Physical Activity: Gradually increasing the intensity, duration, and frequency of physical activity can reduce the risk of overuse injury.

4. Cross-Training: Incorporating different types of physical activities can promote overall fitness.

5. Proper Nutrition: Take a balanced diet rich in nutrients to help maintain strong bones and muscles.

Achilles tendon injury is diagnosed through a physical examination and imaging tests, such as an X-ray, MRI, or ultrasound. During a physical examination, the doctor will check for swelling, tenderness, and range of motion in the ankle and foot. Imaging tests can provide detailed images of the tendon, allowing the doctor to determine the severity and extent of the injury.

Achilles tendon injury typically progresses through three stages:

1. Inflammation: This is the initial stage of injury when the tendon becomes inflamed and swollen, causing pain and stiffness in the heel and calf.
2. Partial Tear: In this stage, the tendon is partially torn or stretched, leading to more severe pain, swelling, and stiffness.
3. Complete Tear: This is the most severe stage of injury, in which the tendon is completely ruptured, leading to sudden, severe pain and an inability to walk or stand.

The treatment for Achilles tendon depends on the severity and type of injury. Here are some common treatment options for Achilles tendon injury:

1. Rest and Ice: Rest the affected leg and apply ice.
2. Physical Therapy: Physical therapy exercises can help improve range of motion, strength, and flexibility of the Achilles tendon and surrounding muscles.
3. Immobilisation: Wearing a cast, brace, or walking boot can immobilise the affected leg and allow the tendon to heal.
4. Medications: Over-the-counter pain relievers can help reduce pain and inflammation.
5. Surgery: In severe cases of Achilles tendon injury, surgery may be necessary to repair or reconstruct the tendon.

The recovery and aftercare of Achilles tendon injury involve several steps to ensure a safe and effective return to physical activity. Here are some essential steps in the recovery and aftercare process:

1. Gradual Return to Physical Activity: Gradually reintroduce physical activity, starting with low-impact exercises and gradually increasing the intensity and duration.
2. Physical Therapy: Continue with physical therapy exercises to maintain strength and flexibility of the Achilles tendon and surrounding muscles.
3. Follow-Up Care: Regular follow-up visits with the doctor can monitor the healing process and ensure proper aftercare.
4. Proper Nutrition and Hydration: Maintaining a balanced diet and staying hydrated can promote healing and reduce the risk of further injury.
5. Wear Proper Footwear: Continue to wear shoes that provide adequate support and cushioning for the feet and ankles.
6. Injury Prevention: Continue to engage in injury prevention strategies such as warm-up and stretching, gradual increase in physical activity, and cross-training.
