Preoperative mental health significantly impacts patient satisfaction after joint replacement surgery. Lower mental health scores before surgery predict dissatisfaction one year later.

Area of Science:

  • Orthopedic Surgery
  • Patient-Reported Outcomes
  • Psychological Health

Background:

  • Patient dissatisfaction after total joint arthroplasty affects up to 30% of individuals.
  • Identifying preoperative predictors is crucial for improving patient outcomes.

Purpose of the Study:

  • To identify patient-level factors before surgery that predict dissatisfaction one year after hip or knee replacement.
  • To understand the relationship between preoperative psychological status and postoperative satisfaction.

Main Methods:

  • 1720 patients undergoing primary hip or knee replacement were surveyed.
  • Demographic data, BMI, sex, comorbidities, and education were collected.
  • The Western Ontario McMaster University Osteoarthritis Index (WOMAC) and SF-36 (including Mental Health) assessed function and quality of life pre- and post-surgery.

Main Results:

  • No demographic differences were found between satisfied and dissatisfied patients.
  • A lower preoperative SF-36 Mental Health score was an independent predictor of dissatisfaction (p < 0.05).
  • Patient satisfaction did not correlate with changes in WOMAC scores.

Conclusions:

  • Preoperative mental health is a key determinant of patient satisfaction following joint replacement.
  • Further research should explore preoperative psychological interventions to enhance subjective surgical outcomes.
