Hafkamp FJ, de Vries J, Gosens T, et al. - Hip and knee arthroplasty patients were examined for different trajectories of physical symptoms from presurgery to 1 year postsurgery. In addition, researchers relate this to preoperative anxiety and depressive symptoms. The Hip injury and Osteoarthritis Outcome Score or the Knee injury and Osteoarthritis Outcome Score was obtained for 345 patients to determine their preoperative and postoperative pain, stiffness, and function, presurgery, and 3, 6, and 12 months postsurgery. Analysis revealed significant but different correlation of anxiety and depressive symptoms with the distinct physical symptoms examined. Differential effect of time was observed on pain, function, and stiffness between subgroups of patients. Knee patients mostly had least improvement. A combination of high levels of both anxiety and depressive symptoms characterized least improvement in pain. There was independent correlation of anxiety and depressive symptoms with less reduction in stiffness while higher depressive symptoms characterized little improvement in function.
