Difference between osteoarthritis and tenosynovitis

Osteoarthritis and tenosynovitis are two different diseases that differ mainly in where they occur and what causes them. Osteoarthritis primarily affects the cartilage in the joints, while tenosynovitis involves the sheath around the tendon. Treatments include medication, physical therapy, and lifestyle changes.

1. Causes and treatment of osteoarthritis

Osteoarthritis is a degenerative joint disease that is primarily related to the wear and degeneration of articular cartilage. Genetic factors may increase the risk of the disease, especially in people with a family history of osteoarthritis. Environmental factors such as long-term overuse of joints, obesity or joint trauma can also accelerate cartilage degeneration. Physiological factors such as aging and changes in hormone levels can also affect joint health. Pathologically, osteoarthritis may progress from mild joint pain to severe joint deformity and dysfunction.

Treatments include:

Drug treatment: Nonsteroidal anti-inflammatory drugs such as ibuprofen, joint lubricant injections such as hyaluronic acid, and analgesics such as acetaminophen are commonly used.

Physical therapy: Heat, cold, ultrasound therapy, and range of motion exercises are used to relieve symptoms.

Lifestyle adjustments: Controlling weight, avoiding overuse of joints, and choosing low-impact exercises such as swimming and cycling can help reduce joint burden.

2. Causes and treatment of tenosynovitis

Tenosynovitis is an inflammation of the sheath surrounding a tendon, usually caused by overuse or repetitive motion. Environmental factors such as long-term manual labor, sports injuries or poor posture may lead to tenosynovitis. Physiological factors such as tendon aging or chronic diseases such as diabetes also increase the risk of tenosynovitis. Pathologically, tenosynovitis may progress from mild local pain to severe limitation of movement.

Treatments include:

Drug treatment: Use nonsteroidal anti-inflammatory drugs such as diclofenac and local hormone injections such as prednisolone to relieve inflammation.

Physical therapy: Rest, ice, massage, and stretching exercises are used to relieve symptoms.

Lifestyle adjustments: Avoiding repetitive movements, using protective gear to protect the affected area, and adjusting working posture can help prevent recurrence.

Although osteoarthritis and tenosynovitis have similar symptoms, their causes and treatments are different. Osteoarthritis focuses on protecting and repairing the joint cartilage, while tenosynovitis focuses on reducing inflammation and pressure around the tendons. Early diagnosis and targeted treatment are the key to improving prognosis. If symptoms persist or worsen, it is recommended to seek medical attention in a timely manner for professional evaluation and treatment.
