Personality, function and satisfaction in patients undergoing total hip or knee replacement.

Area of Science:

• Orthopedics
• Psychology
• Health Outcomes Research

Background:

• Investigating the link between personality and patient-reported outcomes in total hip (THA) and knee arthroplasty (TKA).
• Understanding how personality influences perceived function and health before and after joint replacement surgery.

Purpose of the Study:

• To examine the association between personality types and joint-specific function, general physical health, and mental health in THA and TKA patients.
• To determine if personality traits are independent predictors of surgical outcomes.

Main Methods:

• Utilized the Eysneck Personality Questionnaire (EPQ-BV) for personality assessment.
• Employed the Short-Form 12 (SF-12) and EuroQol (EQ-5D) for general health measures.
• Assessed joint-specific function using the Oxford hip or knee score.

Main Results:

• An "unstable introvert" personality was linked to poorer pre-operative function and health in hip arthroplasty patients.
• Poorer general health was observed in knee arthroplasty patients with "stable extrovert" and "unstable introvert" types.
• Pre-operative function and health, not personality, were the primary predictors of surgical outcomes; comorbidity was a significant covariate.

Conclusions:

• Personality may influence how patients perceive and interact with their health and function post-arthroplasty.
• Identifying specific personality traits could aid in tailoring patient education and management strategies.
• Characterizing personality traits may improve the interpretation of patient-reported outcome measures in arthroplasty research.
