Which age group is most commonly affected by osteoarthritis?

Osteoarthritis is a degenerative joint disease that typically occurs as a result of wear and tear on the joints over time. The condition primarily affects older adults due to the gradual breakdown of cartilage, which cushions the joints. As individuals age, the likelihood of developing osteoarthritis increases significantly, particularly after the age of 50. This is largely because the cumulative effects of biomechanical stress, previous joint injuries, and genetic predisposition become more pronounced in older populations. While osteoarthritis can, in some rare cases, affect younger individuals, it is most prevalent in older adults who are more likely to experience its symptoms, such as joint pain, stiffness, and decreased mobility. Therefore, stating that older adults, usually over 50, are the age group most commonly affected captures the epidemiology of osteoarthritis accurately.
