Basic Calcium Phosphate (BCP) disease

Basic Calcium Phosphate (BCP) disease is a condition characterised by the deposition of calcium phosphate crystals in soft tissues, particularly in joints and tendons, leading to inflammation and pain. It is clinically significant as it can mimic other forms of arthritis and contribute to joint degeneration, complicating diagnosis and management. A key association is its link to rotator cuff disease, where BCP deposits can exacerbate shoulder pain and dysfunction.
