Preoperative health-related quality of life is independently associated with postoperative mortality risk following total hip or knee arthroplasty : seven to eight years’ follow-up.

The primary aim was to assess whether preoperative health-related quality of life (HRQoL) was associated with postoperative mortality following total hip arthroplasty (THA) and knee arthroplasty (KA). Secondary aims were to assess whether patient demographics/comorbidities and/or joint-specific function were associated with postoperative mortality.
