BACKGROUND: While many factors have been shown to influence patient willingness to have total joint arthroplasty, factors associated with changes in patient willingness to have arthroplasty have not been studied. The objective of this research is to identify predictors of change in patient willingness to have total knee arthroplasty (TKA).
METHODS: Patient willingness to have TKA as well as questionnaire, clinical, and radiographic data, were obtained from the Osteoarthritis Initiative (OAI) for individuals with, or at high risk for developing knee OA. Mixed effects ordinal logistic regressions were employed to assess the relationships between 40 predictors and change in willingness to have surgery. Predictors significant in univariate models were included in a multivariable analysis.
RESULTS: Three thousand three hundred and ninety-four OAI patients were included in our analysis. Between baseline and follow-up, 462 (13.6%) became more willing and 533 (15.7%) became less willing to have TKA. After controlling for demographic factors in multivariable analysis, patients with higher income and expected difficulty with postoperative walking were more likely to increase their willingness to have TKA. General health, race, and knee injections within the past six months approached significance with regard to increasing willingness to have TKA over time.
CONCLUSION: Income and expectations of difficulty walking postoperatively were significantly associated with changes in patient willingness to have TKA independent of age, sex, health coverage, employment, marriage status, and knee pain. Understanding factors influencing patient willingness to have surgery may be instrumental in counseling and addressing the mismatch of OA disease burden to surgical utilization.
