Selected Papers from the 2015 European Knee Society MeetingA New Prediction Model for Patient Satisfaction After Total Knee Arthroplasty
Section snippets
Materials and Methods
All patients were identified from an established and prospectively collected arthroplasty outcome database at our center, which is in use since 2013 and was specifically developed to evaluate patient-reported outcomes. At the time of analysis, 436 primary TKA patients were included in this database of which 113 met the eligibility criteria outlined hereafter.
(1) Undergoing primary TKA for arthritis (including primary osteoarthritis [OA], rheumatoid arthritis, and posttraumatic OA), (2) ability
Results
The mean age of patients was 65.2 (SD 9.1, range 41-91). Fifty-six percent were female and 50% were right knees. The mean BMI was 29.3 (SD 4.8, range 17-46).
Patient demographics and characteristics are listed in Table 1 and Table 2.
No significant demographic differences were observed between satisfied and dissatisfied patients (Table 3).
Overall satisfaction rate in our study was found to be 88%. Breakdown into different groups according to the possible answers revealed that 41 patients were
Discussion
The overall satisfaction rate of 88% observed in this study is similar to previous reported studies 6, 9. While most other studies dichotomize patient satisfaction in 2 groups, namely satisfied and dissatisfied 6, 20, we consider satisfaction as a continuous variable based on the KSS satisfaction subscore. After categorizing this score into satisfied (a score of ≥20), neutral (score = 20), and dissatisfied (score < 20), 79% was found to be satisfied, 9% neutral, and 12% dissatisfied. However,
Conclusion
We have demonstrated that patient satisfaction at 3 months following TKA is correlated with several preoperative variables including symptoms, pain, awareness of the knee, and anxiety/depression. The development of this new sensitive prediction tool for patient satisfaction following TKA may allow surgeons and patients to evaluate the risks and benefits of surgery on an individual basis. The predictive 10-question score will anticipate on 36% of the postoperative satisfaction with a sensitivity
