Summary
Patient expectations significantly impact total knee arthroplasty outcomes. Unfulfilled expectations correlate with dissatisfaction, highlighting the need for realistic preoperative counseling to improve patient satisfaction after knee replacement surgery.
Area of Science:
- Orthopedic Surgery
- Patient Outcomes Research
- Health Psychology
Background:
- A significant percentage of patients (5-10%) report dissatisfaction following total knee arthroplasty (TKA).
- Unrealistic patient expectations are frequently cited as a contributing factor to this dissatisfaction.
- A comprehensive systematic review on this topic is currently lacking.
Purpose of the Study:
- To systematically review the existing literature on the relationship between preoperative expectations and patient satisfaction after total knee arthroplasty.
- To synthesize the evidence regarding how different types of expectations influence TKA outcomes.
- To identify gaps in current research and provide recommendations for future studies.
Main Methods:
- A systematic literature search was conducted across multiple databases (PubMed, MEDLINE, Embase, Cochrane, PsycINFO, CINAHL, Web-of-Science).
- Inclusion criteria comprised prospective and retrospective studies with a minimum six-month follow-up.
- Study selection, quality assessment, and evidence synthesis were performed independently by two reviewers.
Main Results:
- Eight studies met the inclusion criteria from an initial search of 6802 articles.
- Limited evidence suggests no significant link between expectations and satisfaction regarding recreational limitations, walking distance, walking aid use, or recovery time.
- Conflicting evidence exists regarding general improvement and pain reduction expectations, while moderate evidence indicates unfulfilled expectations are linked to higher dissatisfaction.
Conclusions:
- Prospective research on expectations and TKA patient satisfaction is limited and yields heterogeneous results.
- Conclusions drawn from current data should be interpreted with caution due to study variability.
- Future research requires standardization and the use of validated questionnaires to clarify the relationship between expectations and satisfaction.
