Objective:

To investigate the association between pain during daily activities and patient satisfaction following total hip and total knee arthroplasty.

Approach:

Key Findings:

• 93% of total hip arthroplasty patients reported satisfaction compared to 82% of total knee arthroplasty patients.
• Postoperative pain scores had a stronger association with satisfaction than functional scores.
• Each 1-standard-deviation improvement in pain score was associated with 2.8 times the odds of higher satisfaction for hip and 3.6 times for knee arthroplasty.
• Walking on flat ground and stair climbing were most strongly associated with satisfaction.
• Total hip arthroplasty patients were younger, had lower body mass index, and fewer comorbidities compared to total knee arthroplasty patients.

Interpretation:

Pain during common daily activities was more closely linked to patient satisfaction than functional limitations after arthroplasty.

Limitations:

• Outcomes evaluated only at 1 year, limiting generalizability to later follow-ups.
• Exclusions due to missing data may introduce bias.
• Various methods for measuring satisfaction could affect results.
• Complete outcomes were available for 74% of total hip arthroplasties and 72% of total knee arthroplasties.

Conclusion:

Postoperative pain significantly influences satisfaction following total hip and total knee arthroplasty, particularly during specific activities.
