Tendonitis vs. Tendinosis: Deciphering the Differences in Diagnosis and Treatment

Tendon injuries are common afflictions that can cause pain and limit mobility. Among the various tendon conditions, tendonitis and tendinosis are often confused due to their similar names. However, understanding the disparities between the two is crucial for effective diagnosis and treatment. In this blog post, we'll delve into the disparities between tendonitis and tendinosis, shedding light on their causes, symptoms, diagnostic methods, and treatment approaches.

Differentiating Tendonitis and Tendinosis

1. Tendonitis: Tendonitis, also known as tendinitis, refers to inflammation of a tendon, usually resulting from overuse or repetitive stress. It typically involves acute pain, swelling, and tenderness in the affected area. Tendonitis often occurs in areas prone to repetitive movements, such as the shoulders, elbows, wrists, knees, and ankles.

2. Tendinosis: In contrast, tendinosis is a chronic degenerative condition characterized by microtears, collagen degeneration, and tissue breakdown within the tendon. Unlike tendonitis, tendinosis does not involve significant inflammation, and symptoms may develop gradually over time. Common symptoms include chronic pain, stiffness, and weakness in the affected tendon.


1. Tendonitis Diagnosis: Tendonitis is typically diagnosed based on clinical evaluation, medical history, and physical examination. Imaging tests such as ultrasound or MRI may be used to assess the extent of inflammation and rule out other potential causes of pain.

2. Tendinosis Diagnosis: Tendinosis diagnosis often involves a combination of clinical assessment and imaging studies. Ultrasound or MRI may reveal signs of tendon degeneration, including changes in tendon thickness, texture, and integrity.

Treatment Approaches

1. Tendonitis Treatment: Treatment for tendonitis focuses on reducing inflammation, relieving pain, and promoting healing. Common interventions include rest, ice therapy, anti-inflammatory medications, physical therapy, and activity modification. In severe cases, corticosteroid injections or surgery may be considered.

2. Tendinosis Treatment: Tendinosis treatment aims to stimulate tendon healing and promote tissue regeneration. Modalities such as eccentric exercise therapy, shockwave therapy, platelet-rich plasma (PRP) injections, and extracorporeal shockwave therapy (ESWT) may be employed to facilitate tendon repair and improve function.


While tendonitis and tendinosis share similarities in symptoms and presentation, they represent distinct pathological conditions with different underlying mechanisms. Understanding the disparities between tendonitis and tendinosis is essential for accurate diagnosis and appropriate treatment selection. By recognizing the nuances of these conditions and implementing targeted interventions, healthcare providers can effectively manage tendon injuries and optimize patient outcomes.
