Fontana MA, Islam W, Richardson MA, et al. - This study was undertaken to investigate employed patients’ presenteeism and absenteeism before and after total joint arthroplasty (TJA). Researchers assessed presenteeism (0-100 scale, 100 full performance) and absenteeism using the World Health Organization’s Health and Work Performance Questionnaire before and after TJA among a convenience sample of employed patients. In this study, 636 primary, unilateral TJA patients responded to an enrollment email, confirmed employment, and completed a pre-operative survey (mean age: 62.1, 55.3% female). According to the findings, presenteeism and absenteeism were similarly costly among employed patients before TJA. The outcomes highlighted that after, employed patients reported increased performance, concentrated among those with declining performance leading up to surgery.
