What joints show evidence of degeneration in nearly all individuals as aging progresses?

Nearly all individuals show evidence of degeneration in the knee and hip joints as they age. These joints are weight-bearing and experience significant stress over time, leading to conditions such as osteoarthritis. Additionally, the spine, particularly the intervertebral discs and facet joints, often exhibits degenerative changes with aging. These degenerative processes can result in pain, reduced mobility, and decreased quality of life.
