TENDINITIS, TENDINOSIS, AND TENDINOPATHY

Are you experiencing tendon pain and hearing terms like tendinitis, tendinosis, and tendinopathy without fully understanding the difference? Don’t worry—you’re not alone. In this article, we clarify these often-confused terms and explain how to recognize, treat, and effectively recover from a tendinopathy, including the common supraspinatus tendinopathy in the shoulder.

 

Tendinopathy, Tendinitis, or Tendinosis: What’s the Difference?

Let’s start by clarifying the difference between tendinitis and tendinopathy:

• Tendinitis: The suffix “-itis” indicates inflammation. Tendinitis is an acute inflammation of the tendon, usually occurring after unusual or excessive stress.
• Tendinopathy: A broader term describing any tendon-related pain, whether or not inflammation is present. It encompasses tendinitis, tendinosis, and other tendon disorders.
• Tendinosis: Refers to chronic degeneration of the tendon, with disorganized fibers and no active inflammatory process.

In other words, tendinitis is a specific type of tendinopathy, but not all tendinopathies are tendinitis.

 

How Does Tendinopathy Develop?

Tendinopathy often arises after:

• Unusually intense effort (e.g., painting a house in a weekend)
• Resuming sport after a long period of inactivity (e.g., hockey, tennis)
• Repetitive movements without proper preparation

Initially, there may be inflammation (tendinitis), but if not properly managed, the tendon can progress to tendinosis, where fibers become disorganized, weaker, and cause chronic pain.

 

Supraspinatus Tendinopathy: A Common Location

Among the most common tendinopathies, the supraspinatus tendon is frequently affected in individuals performing repetitive arm movements (swimming, tennis, baseball, hockey) or in occupations requiring heavy shoulder use.

The supraspinatus is part of the rotator cuff at the top of the shoulder. Its irritation or degeneration causes:

• Pain when lifting the arm above shoulder height
• Difficulty sleeping on the affected side
• Weakness during lifting or rotating the arm

 

Effective Treatments for Tendinopathy

Treatment is based on several key principles:

1. Load Management

   • Relative rest is essential: limit painful movements while maintaining adapted physical activity to ensure good blood flow. Full immobilization is rarely recommended.

2. Progressive Eccentric Exercises

   • Eccentric exercises are fundamental. They stretch and strengthen the tendon under controlled load, promoting fiber reorganization and tendon strengthening.

   • Your physiotherapist will guide you to:

     • Start without excessive pain

     • Gradually increase load

     • Ensure proper movement control to prevent recurrence

3. Motor Control

   • Quality of movement is critical to prevent re-irritation. Specific motor control work is integrated, especially for supraspinatus tendinopathy, to optimize arm-lifting movements.

    

 

Complementary Approaches

Additionally, physiotherapists may use:

• Manual Therapy: Joint mobilizations and myofascial releases to improve mobility
• Cryotherapy and Thermotherapy: Ice or heat application to temporarily reduce pain
• Therapeutic Education: Guidance on activity dosing and correcting posture or movement errors
• Neural Mobilizations: If secondary nerve tension worsens symptoms

 

Recovery Time for Tendinopathy

Healing depends on:

• Severity (mild inflammation vs established tendinosis)
• Promptness of intervention
• Adherence to a progressive exercise plan

Average recovery times:

Type of Tendinopathy	Estimated Recovery Time
Acute Tendinitis	2–6 weeks
Chronic Tendinopathy / Tendinosis	2–6 months

Patience, gradual progression, and consistency are key to successful recovery.
