How does psoriatic arthritis affect tendons
How does psoriatic arthritis affect tendons Psoriatic arthritis (PsA) is a chronic autoimmune condition primarily known for its effects on the skin and joints. While much attention is given to its impact on the larger joints, it also has a significant influence on tendons, which are the fibrous tissues connecting muscles to bones. Tendons play a crucial role in facilitating movement and providing stability, and their health is vital for maintaining everyday function.
In PsA, the immune system mistakenly targets healthy tissues, leading to inflammation that can affect not only the joints but also the entheses — the specialized sites where tendons and ligaments attach to bones. This inflammation at the entheses is a hallmark of psoriatic disease and can lead to a condition called enthesitis. Enthesitis manifests as pain, swelling, and tenderness at these attachment points, commonly affecting areas such as the heels, Achilles tendons, elbows, and the base of the fingers.
How does psoriatic arthritis affect tendons The inflammation caused by PsA can weaken tendons over time. Chronic enthesitis leads to tissue damage, and in some cases, can result in tendon thickening, calcification, or even partial tears. This deterioration impairs the tendons’ ability to perform their functions efficiently, often causing pain and reducing mobility. For instance, inflammation at the Achilles tendon can make walking or standing uncomfortable, while involvement of the tendons in the fingers can impair grip and dexterity.

This condition can cause swelling, warmth, and increased pain along the affected tendons. Over time, persistent inflammation and resulting tissue damage may lead to fibrosis, reducing the tendons’ elasticity and further impairing movement.
The effects of PsA on tendons are not just localized; they can also have systemic repercussions. Degenerative changes in tendons can increase the risk of spontaneous ruptures, especially in areas subjected to frequent stress. This risk underscores the importance of early diagnosis and effective management to prevent long-term damage. How does psoriatic arthritis affect tendons
Managing tendon involvement in psoriatic arthritis involves a combination of medication and physical therapy. Non-steroidal anti-inflammatory drugs (NSAIDs), biologic agents, and disease-modifying antirheumatic drugs (DMARDs) are commonly used to control inflammation. Biologic therapies targeting specific immune pathways have shown promising results in reducing enthesitis and tenosynovitis. Physical therapy and exercises tailored to strengthen surrounding muscles and improve flexibility are also vital, helping to alleviate pain and prevent further injury.

In conclusion, psoriatic arthritis significantly impacts tendons through mechanisms of inflammation and tissue degeneration. Recognizing the signs of tendon involvement and seeking prompt medical care is essential for reducing long-term damage and maintaining quality of life. Early intervention can help preserve tendon function, minimize pain, and prevent complications such as tears or ruptures, ultimately improving outcomes for individuals living with this complex autoimmune disease.
