Tenosynovitis vs. Tendonitis — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on April 26, 2024
"Tenosynovitis" is the inflammation of the sheath surrounding a tendon, causing pain and swelling, while "tendonitis" refers to the inflammation of the tendon itself, often leading to localized pain and impaired function.

Key Differences
Tenosynovitis involves inflammation of the synovial sheath that encases a tendon, which can cause pain, swelling, and movement difficulty. On the other hand, tendonitis focuses on the inflammation of the tendon fibers themselves, typically resulting from overuse or strain.
While tenosynovitis can lead to a feeling of stiffness or creaking when moving the affected tendon (a phenomenon known as crepitus), tendonitis usually presents as localized pain that worsens with movement of the affected area.
Tenosynovitis often affects tendons that are enclosed within a synovial sheath, commonly seen in the hands, wrists, and ankles. Conversely, tendonitis is common in larger tendons such as the Achilles, rotator cuff, and patellar tendons, which are frequently subjected to repetitive stress.
Diagnosis of tenosynovitis may involve imaging tests to view the inflamed sheath and fluid around the tendon, whereas tendonitis might be diagnosed primarily based on medical history and physical examination focusing on tenderness and pain in response to tendon movement.
Management of tenosynovitis often includes rest, immobilization, and anti-inflammatory medications, and in some cases, corticosteroid injections or surgery. Tendonitis treatment typically emphasizes rest, ice, compression, and elevation (RICE), along with physical therapy to strengthen surrounding muscles and relieve stress on the tendon.

Tenosynovitis
Inflammation of the synovial sheath surrounding a tendon.
Repetitive wrist movements can lead to tenosynovitis, causing pain along the thumb side of the wrist.
Tendonitis
Symptoms include pain that intensifies with movement.
He experienced sharp pain in his shoulder, indicative of tendonitis.
Tenosynovitis
Often associated with systemic inflammatory diseases.
Rheumatoid arthritis often manifests as tenosynovitis in various joints.
Tendonitis
May lead to tendon degeneration if chronic.
Chronic tendonitis can weaken a tendon over time, leading to higher risk of tears.
Tenosynovitis
Can occur from infection, repetitive use, or injury.
Improper use of garden tools frequently leads to tenosynovitis.
Tendonitis
Treatment aims to reduce inflammation and stress on the tendon.
Physical therapy for tendonitis focuses on strengthening and flexibility exercises.
Tenosynovitis
Treatment may involve surgical intervention in severe cases.
Severe tenosynovitis might require surgery to release the tendon sheath.
Tendonitis
Commonly affects athletes and older adults.
Tendonitis is a frequent issue for tennis players.
Tenosynovitis
Characterized by swelling and a creaking sensation during tendon movement.
She felt a creaking sensation in her ankle, a symptom of tenosynovitis.
Tendonitis
Inflammation of a tendon, typically due to overuse.
Jogging with improper footwear can cause Achilles tendonitis.
Tenosynovitis
Tenosynovitis is the inflammation of the fluid-filled sheath (called the synovium) that surrounds a tendon, typically leading to joint pain, swelling, and stiffness. Tenosynovitis can be either infectious or noninfectious.

Common Curiosities
Can both conditions lead to decreased range of motion?
Yes, both can impair movement, but tenosynovitis may also cause a gritty feeling or crepitus due to inflammation of the sheath.
What differentiates the pain between tenosynovitis and tendonitis?
Tenosynovitis pain can be more diffuse along the course of the tendon sheath, whereas tendonitis pain is often more focused at a specific point on the tendon.
Are there specific stretches or exercises recommended for recovery from tendonitis?
Yes, gentle stretching and strengthening exercises tailored to the affected tendon can aid recovery and prevent future injuries, often guided by a physical therapist.
How long does it typically take to recover from tenosynovitis or tendonitis?
Recovery can vary from weeks to months, depending on severity and treatment efficacy.
Can tenosynovitis and tendonitis be prevented?
Yes, by avoiding repetitive strain, using proper techniques and equipment, and engaging in exercises to strengthen the muscles around tendons.
Are tenosynovitis and tendonitis only caused by physical activity?
No, both can also result from inflammatory diseases, and tenosynovitis can be caused by infection.
Can lifestyle changes help manage tenosynovitis or tendonitis?
Yes, lifestyle changes such as ergonomic adjustments, regular exercise, and proper rest can help manage symptoms and prevent recurrence.
What are the long-term effects of untreated tenosynovitis or tendonitis?
Untreated tenosynovitis can lead to chronic pain and limited mobility, potentially causing permanent damage to the tendon sheath. Chronic tendonitis can result in tendon weakening or rupture.
What are common misconceptions about tenosynovitis and tendonitis?
A common misconception is that they are minor issues that do not require medical attention. Both can lead to serious complications if not properly treated.
What role does diet play in the treatment of tenosynovitis and tendonitis?
A diet rich in anti-inflammatory foods can help reduce symptoms. Foods high in omega-3 fatty acids, antioxidants, and vitamins can support tendon health.
s surgery a common treatment for either condition?
Surgery is more common for severe or chronic tenosynovitis to release the tendon sheath, while it is less commonly required for tendonitis unless there is a tendon rupture or significant degeneration.
How does one differentiate between tenosynovitis and tendonitis in early stages?
Early differentiation can be challenging without medical imaging, but tenosynovitis may present with more swelling and a rubbing or creaking sensation, while tendonitis typically shows localized tenderness and pain during movement.
