Why Are so Many Patients Dissatisfied With Knee Replacement Surgery? Exploring Variations of the Patient Experience

• Conditions: Total Knee Arthroplasty

• Registration Number: NCT01466920
• Lead Sponsor: University of British Columbia

Brief Summary

The goal of this research is to fill the knowledge gap relating to why up to 20 percent of total knee arthroplasty (TKA) patients are dissatisfied with their clinical outcomes and to answer the research question: What are the drivers of variation in the patient experience with primary (ie. not revision) TKA?

Detailed Description

Purpose: Among patients with a diagnosis of osteoarthritis and who are undergoing total knee arthroplasty:

1. To identify variations in the patient experience with primary knee replacement surgery by measuring clinical outcomes, health status, and patient satisfaction; and

2. To explore the factors contributing to good/poor clinical and patient outcomes, such as surgical factors, health system factors, socioeconomic demographic factors and psychological factors.
