Osteoarthritis tends to involve joints in an uneven, one‑sided way rather than affecting many joints on both sides. This asymmetric pattern comes from degenerative wear and tear that hits certain joints harder due to load, prior injury, or localized stress, so radiographs show changes in individual joints rather than across the whole limb or body at once. Typical radiographic signs at affected joints include narrowing of the joint space with the formation of osteophytes and subchondral sclerosis, reflecting local cartilage loss and bone response.

This asymmetric, often focal distribution helps distinguish OA from inflammatory arthritides like rheumatoid arthritis, which usually shows symmetric involvement across multiple joints.
