Achilles Tendonitis vs Tendinosis: What’s the Difference?

Understanding Achilles Tendonitis and Tendinosis

At Foot & Ankle Associates of Southern NH, located in Derry, New Hampshire, we often encounter patients confused about Achilles tendon pain. Two common conditions, Achilles tendonitis and Achilles tendinosis, sound similar but have distinct characteristics. Understanding their differences can be crucial for effective treatment and recovery.

What is Achilles Tendonitis?

Achilles tendonitis is an inflammatory condition of the Achilles tendon, the band of tissue that connects your calf muscles to your heel bone. This condition typically occurs due to overuse, particularly in runners or individuals who engage in sports that involve repetitive stress on the tendon, such as basketball or tennis.

What Causes Achilles Tendonitis?

• Overuse: Repeated stress can cause tiny tears in the tendon.
• Poor biomechanics: Flat feet or high arches can lead to abnormal stress on the tendon.
• Inadequate footwear: Wearing worn-out shoes or improper footwear can exacerbate the condition.
• Sudden increase in activity: Starting a new workout routine too quickly can trigger inflammation.

Symptoms of Achilles Tendonitis

Symptoms may include:

• Localized pain along the Achilles tendon, particularly during activity.
• Swelling and tenderness at the back of the heel.
• Stiffness in the morning that improves with movement.
• A feeling of warmth or tightness in the tendon area.

What is Achilles Tendinosis?

Unlike tendonitis, achilles tendinosis is a degenerative condition stemming from chronic overuse. This implies that the tendon has undergone substantial biological changes, including microtears and the degeneration of collagen fibers within the tendon.

What Causes Achilles Tendinosis?

• Long-standing tendonitis: If untreated, acute tendonitis can progress to tendinosis.
• Age-related changes: The tendon's ability to repair itself diminishes with age.
• Chronic overload: Continuous high-impact activities without adequate recovery can lead to degenerative changes.
• Tendon structure changes: Collagen breakdown and disorganization can occur, altering the structural integrity of the tendon.

Symptoms of Achilles Tendinosis

Common symptoms include:

• Chronic pain in the heel that may vary in intensity.
• Stiffness that persists, particularly during prolonged periods of inactivity.
• A noticeable thickening of the tendon.
• Pain during physical activity that may worsen after activity.

How are Achilles Tendonitis and Tendinosis Diagnosed?

At Foot & Ankle Associates of Southern NH, our experienced podiatrists perform a comprehensive evaluation which may include:

• Physical examination to assess pain levels and range of motion.
• Ultrasound or MRI, if necessary, to visualize tendon changes.
• Patient medical history to understand previous injuries or activity levels.

How Can I Treat Achilles Tendonitis and Tendinosis?

Treatment strategies differ between the two conditions:

For Achilles Tendonitis:

• Rest: Reducing or completely eliminating activities that exacerbate pain.
• Ice therapy: Applying ice packs to reduce inflammation.
• Physical therapy: Exercises designed to strengthen the calf muscles and improve flexibility.
• Anti-inflammatory medications: Over-the-counter drugs can help alleviate pain and swelling.

For Achilles Tendinosis:

• Rehabilitation exercises: Focused on gradual loading and strengthening of the tendon.
• Shockwave therapy: Promotes healing in degenerative tendons.
• Surgery: In cases of severe degeneration, surgical options may be considered to repair the tendon.
• Custom orthotics: Can help alleviate stress on the tendon and improve biomechanics.
