Osteoarthritis (OA) is the most common type of arthritis, characterized by pain, swelling, heat, loss of motion, and tenderness in the affected joint. It occurs due to aging and the breakdown of the articular cartilage. Treatments include lifestyle changes, medications, and joint replacement surgery.

Step-by-step explanation:

Osteoarthritis (OA), which is the most common type of arthritis, typically affects large joints like the knee. It is characterized by symptoms such as pain, swelling, heat, loss of motion, and tenderness in the affected joint. Osteoarthritis occurs due to aging and the gradual breakdown of the articular cartilage that covers the bone surfaces in the joint. Risk factors for developing osteoarthritis include joint injuries, physical labor, certain sports activities, and being overweight. Although there is no cure for osteoarthritis, treatments such as lifestyle changes, medications, and joint replacement surgery can help manage the symptoms.
