Discussion
This systematic review on work status after THA and TKA and its determinants shows that the literature on work status afterTHA is more extensive than forTKA. Overall, the majority of patients who are employed before THA or TKA return to work postoperatively. Factors related to work status after THA or TKA included sociodemographic, health and job characteristics. Overall, the methodological quality of the studies was moderate to low, and comparisons of rates and speed of return to work among and between studies on THA and TKA were hampered by large variations in patient selection and measurement methods. Regarding the overall favourable effect of THA and TKA on work status seen in the studies included in this review, we have no similar synthesis of the literature for comparison.
