Work that demands repetitive motions can stress the joints and increase OA risk, says Ali Askari, M.D., division chief of rheumatology with University Hospitals in Cleveland. Research shows that people whose work requires heavy lifting, or excessive kneeling, squatting, or standing—like farming, mining, construction, or professional dancing—are more likely to develop OA. Can’t avoid it? Remember to take breaks! If OA symptoms are too much, talk to your employer about options, says Bill Robinson, M.D., chief of immunology and rheumatology at Stanford Medicine—he has one patient, a postal worker, who transitioned from a walking route to a desk job after developing knee OA.
