What is an example of a condition that results from periarticular fibrosis?

• A. Osteoarthritis
• B. Frozen shoulder
• C. Tendonitis
• D. Ligament sprain

Answer: (B)

Periarticular fibrosis refers to the development of fibrous tissue around a joint, which can occur as a response to injury, inflammation, or immobilization. Frozen shoulder, also known as adhesive capsulitis, is characterized by stiffening and inflammation of the shoulder joint, leading to pain and restricted mobility. This condition results from the thickening and tightening of the shoulder capsule, which is a manifestation of periarticular fibrosis.

In frozen shoulder, the fibrous tissue that develops restricts the normal motion of the shoulder joint and can greatly affect a person's quality of life, leading to difficulty with everyday activities. Understanding that frozen shoulder stems from periarticular fibrosis allows practitioners to target treatment options to reduce inflammation and restore mobility in affected individuals.

While conditions like osteoarthritis and tendonitis involve joint and surrounding soft tissue pathology, they do not specifically result from periarticular fibrosis. Ligament sprains also involve damage but do not equate to the formation of fibrous tissue around a joint in the same way frozen shoulder does. Therefore, frozen shoulder is the condition most directly associated with periarticular fibrosis.
