Which type of arthritis is characterized by wear and tear on the joints?

Osteoarthritis is characterized by the wear and tear on the joints, which occurs primarily due to the aging process and repetitive stress on the joints over time. This degenerative joint disease results in the breakdown of cartilage, leading to pain, stiffness, and loss of joint function. The cartilage, which normally provides a smooth surface for joint movement, becomes damaged, leading to symptoms that can significantly affect an individual's quality of life.

Factors that contribute to osteoarthritis include obesity, previous joint injuries, and genetics, alongside the natural aging process. Unlike rheumatoid arthritis, which is an autoimmune condition causing joint inflammation and deformity, osteoarthritis is primarily mechanical in nature, resulting from cumulative damage rather than an immune response. This distinction helps in the understanding of its pathophysiology and treatment approaches.

Therefore, recognizing osteoarthritis as a degenerative joint condition informs healthcare providers and patients about the need for management strategies focused on pain relief and maintaining mobility.
