Psychological Factors Associated with Function and Health-Related Quality of Life Outcomes following Total Hip or Knee Arthroplasty: An Umbrella Review of Systematic Reviews

There is growing interest in identifying psychological factors associated with outcomes following total hip arthroplasty (THA) or total knee arthroplasty (TKA). However, the available evidence is heterogeneous, and uncertainty remains regarding which psychological factors are most consistently associated with postoperative outcomes following arthroplasty. The aim of this study was to provide an overview of available evidence of association between psychological factors and function or health-related quality of life (HRQoL) after arthroplasty.
