Impact of socioeconomic factors on outcome of total knee arthroplasty

Abstract

Background: Several factors are associated to negative outcomes of total joint replacement such as inappropriate expectations, contralateral knee pain, higher psychological distress, high body mass index, use of a walking aid, advanced age, female gender, lower OA grade and thyroid disease Nonetheless, these findings are often not consistent across studies and the exact strength of the associations between these factors and the outcomes remain elusive. It thus remains a challenge to identify which TKA candidates will likely do well, or do poorly following TKA.
