INTRODUCTION: The purpose of this study is to determine which patient factors predict two-year postoperative met expectations in a cohort of patients undergoing knee surgery. Additionally, this study aims to measure the association between met expectations and postoperative outcomes. METHODS: 319 patients undergoing knee surgery at one institution were studied. Patients completed patient-reported outcome questionnaires prior to surgery and again two years postoperatively. Preoperative Expectations and postoperative Met Expectations were measured using the Musculoskeletal Outcomes and Data Evaluation Management System (MODEMS) Expectations domain. RESULTS: The mean Met Expectations score was significantly lower than the preoperative Expectations Score. Worse two-year Met Expectations were associated with older age, higher BMI, greater comorbidities, more previous surgeries, black race, unemployment, lower income, government insurance, Worker's Compensation, smoking, and no injury prior to surgery. Greater Met Expectations were correlated with better scores on all two-year outcome measures as well as greater improvement on most outcome measures. Race, insurance status, function, mental health, and knee pain were found to be independent predictors of Met Expectations. CONCLUSION: This study identified multiple patient factors and outcome measures that were associated with Met Expectations two years after knee surgery.
