Classification and definition of tendinopathies

Area of Science:

• Orthopedics
• Sports Medicine
• Pathology

Background:

• Tendinopathies are common musculoskeletal conditions affecting tendons.
• Understanding the classification of tendinopathies is crucial for effective treatment.
• Previous classifications may not fully capture the diverse nature of tendinopathies.

Purpose of the Study:

• To classify tendinopathies into distinct categories.
• To differentiate between degenerative and reactive tendinopathies.
• To highlight specific examples of reactive tendinopathies.

Main Methods:

• Review and analysis of existing literature on tendinopathies.
• Development of a new classification system based on lesion origin.
• Categorization of tendinopathies into primary and other types.

Main Results:

• Tendinopathies are classified into two primary categories.
• The majority of tendinopathies fall into the primary category, involving lesions within the tendon substance.
• Not all tendinopathies are degenerative; some, like calcifying tendinitis, are reactive.

Conclusions:

• A two-category classification system for tendinopathies is proposed.
• The distinction between degenerative and reactive processes is important for understanding tendinopathies.
• Calcifying tendinitis serves as a key example of a reactive tendinopathy.
