What is another name for degenerative joint disease?

• A. Rheumatoid arthritis
• B. Post-traumatic arthritis
• C. Osteoarthritis
• D. Infectious arthritis

Answer: (C)

Degenerative joint disease is more commonly known as osteoarthritis. This condition is characterized by the deterioration of cartilage and the underlying bone in joints, leading to pain, stiffness, and decreased mobility. It is typically associated with the wear and tear of the joints over time, making it prevalent in older individuals or those who have experienced joint injuries or stress. Osteoarthritis primarily affects weight-bearing joints such as the hips and knees, but can also impact the hands and spine.

Rheumatoid arthritis, on the other hand, is an autoimmune condition that results in joint inflammation and damage due to the body's immune system attacking its own tissues. Post-traumatic arthritis develops after a joint injury, while infectious arthritis is caused by infections in the joint, which is entirely different from the degenerative process seen in osteoarthritis. Thus, osteoarthritis is accurately identified as another name for degenerative joint disease, highlighting the nature of the condition as one associated with degeneration rather than inflammation or infection.
