Sutured knee. View of a sutured knee showing metal staples and psoriasis following a knee joint replacement operation. The wound edges have been held together by the insertion of equally spaced staples. Knee joint replacements are most commonly performed in elderly patients with osteoarthritis or rheumatoid arthritis. Psoriasis can be seen as thickened patches of inflamed, red skin partially covered by silvery scales. Psoriasis is a chronic disease that tends to recur due to various causes. Skin damage is a possible trigger in this case.
