Which condition is also known as Degenerative Joint Disease?

Degenerative Joint Disease (DJD) is indeed the correct answer, as it is commonly known as osteoarthritis. This condition is characterized by the degeneration of joint cartilage and the underlying bone, which leads to pain, stiffness, and decreased mobility in the affected joints. DJD is often related to wear and tear on the joints over time and can occur as a result of aging, previous joint injuries, or repetitive stress on the joints.

Understanding DJD is essential in the context of joint health since it highlights the importance of managing joint mechanics and mitigating risk factors associated with its progression. Compared to other conditions such as rheumatoid arthritis, osteoporosis, and chronic pain syndrome, DJD specifically targets the deterioration of joint structures, making it distinct and identifiable under its alternate name.
