Which of the following joints are most commonly affected by osteoarthritis?

Osteoarthritis is a degenerative joint disease that commonly affects joints subject to significant weight and pressure over time. Weight-bearing joints, including the hips, knees, and spine, are particularly prone to this condition due to their role in supporting the body's weight during movement and activities. The wear and tear on the cartilage in these joints leads to pain, stiffness, and decreased mobility, which are hallmarks of osteoarthritis.

While other joints, such as the shoulders, elbows, and finger joints, can also be affected by osteoarthritis, the prevalence is significantly higher in weight-bearing joints because they endure more mechanical stress throughout daily life. Understanding this distinction is crucial for recognizing how osteoarthritis impacts mobility and quality of life for affected individuals.
