Which age group is particularly prone to osteoarthritis in the lower extremities?

The correct answer identifies middle-aged and older adults as the age group particularly prone to osteoarthritis in the lower extremities. Osteoarthritis is a degenerative joint disease that tends to develop due to wear and tear on the joints over time, making it more prevalent in individuals as they age.

As people grow older, their cartilage, which cushions the joints, naturally loses elasticity and can deteriorate, leading to pain, stiffness, and decreased mobility. Factors such as previous joint injuries, obesity, genetics, and certain occupations that stress the joints can further increase the risk of developing osteoarthritis in this demographic.

Younger populations, including teenagers and young adults, typically have more resilient joints and fewer instances of osteoarthritis as it is less common in these groups. Children also usually have healthy joint structures, making them less susceptible to this type of degenerative condition. Hence, middle-aged and older adults are the demographic most affected by osteoarthritis in the lower extremities.
