Osteoarthritis (OA)

A progressive and irreversible degenerative joint disease characterized by cartilage breakdown, bone changes, and chronic pain.

Detailed explanation

Osteoarthritis, also known as degenerative joint disease, is a chronic, progressive condition that affects the joints of pets, leading to pain and reduced mobility. It occurs when the protective cartilage within a joint wears down over time, causing bone to rub against bone. This friction leads to inflammation, pain, and the development of bone spurs. OA can be primary, occurring with age, or secondary to an injury, genetic predisposition (like hip or elbow dysplasia), or obesity. While there is no cure, management focuses on alleviating pain, slowing progression, and improving quality of life through a combination of medications, weight management, joint supplements, physical therapy, and sometimes surgery.
