Patient expectations of total knee arthroplasty (TKA) can be managed through education. E-learning is the application of information technology to education. Providing information to patients at the place and time of their choosing, e-learning has the potential to broaden the reach of existing services for patients. This study evaluated whether an e-learning tool could affect whether patients felt their expectations were met and whether they were satisfied with surgery one year following primary TKA. We recruited consecutive patients with osteoarthritis and randomized them to either standard patient education (n=207), or to our standard patient education plus a new e-learning tool (n=209). Preoperative measures were completed following the patients’ Pre-Admission clinic (PAC) visit and prior to accessing the e-learning tool. Postoperative patient reported outcome measures (PROMs) were completed at six weeks, three months and one year after TKA. We used the Postoperative Expectation Questionnaire to measure the degree to which patient expectations had been met and the Patient Acceptable Symptom State (PASS) question to measure patient satisfaction at one year postoperative. We collected several PROMs for descriptive purposes including: new Knee Society Knee Scoring System (KSS); (Pre-Op and Post-Op versions), Knee injury and Osteoarthritis Outcome Score (KOOS), the Medical Outcomes Study 12-Item Short Form Health Survey, version 2 (SF-12), Hospital Anxiety and Depression Scale (HADS), Pain Catastrophizing Scale (PCS), University of California at Los Angeles (UCLA) Activity Score, and the Social Role Participation Questionnaire (SRPQ).Purpose
