Achilles Tendonitis Complete Guide

Achilles Tendonitis Complete Guide


What is Achilles Tendonitis?

Achilles tendonitis is an overuse injury that causes inflammation, pain, and stiffness in the Achilles tendon—the thick band of tissue that connects the calf muscles to the heel bone. It is a common condition among athletes, runners, and people who engage in repetitive activities that put stress on the tendon.


Classify Achilles Tendonitis

Injury / Condition – Achilles tendonitis is classified as a tendon injury caused by repetitive stress, inflammation, and micro-tears in the Achilles tendon. If left untreated, it can develop into a chronic condition or even lead to a tendon rupture.


Achilles Tendonitis Statistics

  • Achilles tendonitis affects about 5-10% of all runners.
  • It is more common in men than women, especially in middle-aged individuals who engage in sports.
  • Around 30% of people with Achilles tendonitis have a history of tight calf muscles or improper footwear.
  • Cases of Achilles injuries are increasing, especially due to a rise in high-impact fitness activities.

Types of Achilles Tendonitis

There are two primary types of Achilles tendonitis:

  1. Non-insertional Achilles Tendonitis – Inflammation occurs in the middle portion of the tendon, usually affecting younger or more active individuals.
  2. Insertional Achilles Tendonitis – Inflammation occurs at the point where the tendon attaches to the heel bone. It can be associated with bone spurs and affects both active and inactive individuals.

Health Signs and Symptoms

Early Detection

Achilles tendonitis usually starts as mild discomfort but can worsen if not managed properly. Paying attention to early symptoms can help prevent long-term issues.

Common Signs and Symptoms:

  • Pain and stiffness in the Achilles tendon, especially in the morning
  • Swelling or thickening of the tendon
  • Increased pain after exercise or activity
  • Tenderness when touching or squeezing the tendon
  • Difficulty flexing the foot or standing on tiptoe
  • A cracking or popping sound when moving the ankle

Anatomy and Physiology

Body Parts Affected:

  • Achilles Tendon – The largest and strongest tendon in the body, connecting the calf muscles to the heel bone.
  • Calf Muscles (Gastrocnemius & Soleus) – Provide power for movement and push-off during walking and running.
  • Heel Bone (Calcaneus) – The point where the Achilles tendon attaches.
  • Ankle Joint – Movement is affected when the tendon is inflamed or injured.

Causes of Achilles Tendonitis

Achilles tendonitis is caused by repetitive stress on the tendon, often due to overuse or improper movement patterns.

Common Causes:

  1. Overuse and Repetitive Strain – Running, jumping, or excessive walking without proper rest.
  2. Sudden Increase in Activity – Rapidly increasing workout intensity or mileage.
  3. Tight Calf Muscles – Limited flexibility puts extra stress on the Achilles tendon.
  4. Improper Footwear – Shoes without proper support can increase strain.
  5. Flat Feet or High Arches – Alters the way force is distributed across the foot and tendon.
  6. Aging & Wear-and-Tear – Natural degeneration of the tendon over time.
  7. Obesity or Excess Weight – Extra weight increases stress on the tendon.

Common Triggers of Achilles Tendonitis

  • Running on hard or uneven surfaces
  • Wearing high heels frequently
  • Playing high-impact sports (basketball, soccer, tennis)
  • Exercising without warming up properly
  • Ignoring early pain or discomfort in the heel or calf

Complications

If left untreated, symptoms may worsen and affect your day-to-day life. Possible complications include:

  • Chronic Pain – Persistent discomfort that limits physical activity.
  • Tendon Weakness – Increased risk of tendon rupture.
  • Achilles Tendon Rupture – A complete tear that may require surgery.
  • Heel Spurs – Bony growths that cause additional pain and stiffness.

Risk Factors

  • Age (Most common in people 30-50 years old)
  • Gender (More frequent in men)
  • High-impact sports participation
  • Poor footwear choices
  • Tight calf muscles
  • Sudden increase in physical activity

Achilles Tendonitis Stages

  1. Mild Stage – Minor discomfort, stiffness in the morning, and slight tenderness.
  2. Moderate Stage – Noticeable pain after activity, slight swelling, and limited ankle movement.
  3. Severe Stage – Pain even at rest, difficulty walking, possible thickening of the tendon.
  4. Tendon Degeneration or Rupture – Severe, chronic pain, tendon weakness, or a full tear.

Prevention

  • Stretch before and after exercise to keep the calf muscles flexible.
  • Wear proper footwear with good arch and heel support.
  • Gradually increase activity levels to avoid overuse injuries.
  • Strengthen the calf muscles to reduce tendon strain.
  • Avoid high heels and unsupportive shoes for prolonged periods.

Achilles Tendonitis Diagnosis

Diagnosis is typically based on a physical exam, medical history, and imaging tests if necessary. A doctor will check for tenderness, swelling, and range of motion limitations in the Achilles tendon.


Tests & Examinations

To confirm Achilles tendonitis and rule out other conditions, a doctor may recommend:

  • Physical Examination – Assessing tenderness, swelling, and flexibility.
  • X-ray – To check for bone spurs or calcification near the tendon.
  • Ultrasound – Visualizes tendon movement and detects inflammation.
  • MRI (Magnetic Resonance Imaging) – Used in severe cases to check for tendon tears.
