What condition involves scar tissue forming around the shoulder joint?

Adhesive capsulitis, often referred to as frozen shoulder syndrome, is a condition characterized by the formation of scar tissue around the shoulder joint, which leads to stiffness, pain, and a significant decrease in range of motion. The capsule surrounding the shoulder joint becomes thickened and tight, resulting in limited movement. This condition can develop due to various factors, including prolonged immobility following injury or surgery, diabetes, or other health conditions.

Although frozen shoulder syndrome is another term commonly used for adhesive capsulitis, the term "adhesive capsulitis" is the more precise medical terminology that specifically describes the pathological development of this condition. The formation of scar tissue is a hallmark of adhesive capsulitis, which differentiates it from other shoulder conditions like a rotator cuff tear or shoulder dislocation, where the mechanisms and implications of injury are distinct.
