Summary
Most patients are satisfied after posterior stabilized total knee arthroplasty (TKA), but dissatisfaction arises from limitations in daily activities like squatting and climbing stairs, which are crucial for function.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Patient Outcomes Research
Background:
- Total knee arthroplasty (TKA) is a common procedure for end-stage knee arthritis.
- A significant minority of patients report dissatisfaction following TKA.
- Understanding patient dissatisfaction drivers is key to improving surgical outcomes.
Purpose of the Study:
- To assess overall patient satisfaction with posterior stabilized TKA.
- To identify specific functional deficits and residual symptoms contributing to dissatisfaction.
- To rank the importance of various functional outcomes for patients.
Main Methods:
- Retrospective analysis of 1013 posterior stabilized TKAs in 748 Chinese patients.
- Utilized patient-completed validated questionnaires.
- Assessed overall satisfaction and importance ranking of 15 specific functions/symptoms.
Main Results:
- Overall patient satisfaction rate was 87.4%.
- High dissatisfaction was noted for activities such as sitting with legs crossed (55.0%) and squatting (51.7%).
- Key desired outcomes included pain relief, improved walking, stair climbing, and return to household work.
Conclusions:
- Approximately 12.6% of patients were dissatisfied with their overall TKA outcome.
- Dissatisfaction was highest for stair climbing and squatting, activities patients deemed most important.
- Addressing functional limitations in stair climbing and squatting is crucial for enhancing patient satisfaction post-TKA.
