Which condition affects the joints and can lead to pain and disability, especially in weight-bearing areas?

Osteoarthritis is a degenerative joint disease that primarily affects the cartilage in joints, particularly those that bear weight, such as the hips, knees, and spine. As the cartilage wears down over time, it can lead to pain, stiffness, and loss of movement, which may severely affect a person's ability to perform daily activities. This condition is characterized by the deterioration of the joint structure and is often associated with aging, though it can also result from previous joint injuries or overuse.

The nature of osteoarthritis as a weight-bearing issue is significant, as the joints under the most stress during daily activities are often the most affected. Therefore, individuals with osteoarthritis may experience increased discomfort and functional limitations as they engage in weight-bearing activities, further emphasizing how this condition uniquely impacts the quality of life.
