Abstract

INTRODUCTION: Over the past couple of decades, the definition of success after total knee arthroplasty (TKA) has shifted away from clinician-rated metrics, and towards the patient's subjective experience. Therefore, understanding the aspects of patient recovery that drive three to five-year satisfaction after TKA is crucial. The aims of this study were to (1) determine the one-year postoperative factors, specifically patient-reported outcome measures (PROMs), that were associated with three- and five-year postoperative satisfaction and (2) understand the factors that drive those who are not satisfied at one-year postoperatively to become satisfied later in the postoperative course.METHODS: This was a retrospective study of 402 TKA patients who were gathered prospectively and presented for their 1 year follow-up. Demographics were collected preoperatively, and patient-reported outcomes were collected at one-, three-, and five-years postoperatively. Logistic regressions were used to identify the factors at one-year that were associated with three- and five-year satisfaction.RESULTS: Associations between 1-year PROMs with 3-year satisfaction were observed. Longer term satisfaction at five-years was more closely associated with EuroQol 5 Dimension Mobility, Activity Score, and Numerical Rating Scale Satisfaction. Of those who were not satisfied at one-year, EQ-5D Mobility, Knee Disability Osteoarthritis Outcome Score Function in Sport and Recreation, and Satisfaction were associated with becoming satisfied at three-years.CONCLUSIONS: The one-year PROMs were found to be associated with satisfaction at three to five years after TKA. Importantly, many of the PROMs that were associated with three- to five-year satisfaction, especially in those who were not originally satisfied at one-year, were focused on mobility and activity level.
