BackgroundThe aims of this study were to assess patients' preoperative expectations of the outcome of total hip or knee arthroplasty (THA/TKA) regarding specific aspects of functioning and to determine to what extent each expectation was fulfilled after 1 year.MethodsThis was a prospective cohort study. Preoperative expectations and their fulfillment after 1 year were measured with the Hospital for Special Surgery Hip/Knee arthroplasty Expectations Surveys. Preoperative and postoperative scores were subtracted to calculate whether expectations were unfulfilled, fulfilled, or exceeded.ResultsA total of 343 THA and 322 TKA patients with complete follow-up were included. Preoperatively, >60% of patients (both THA/TKA) expected to get back to normal or have much improvement in 19 of 20 (THA) and 12 of 19 (TKA) items. Expectations were fulfilled or exceeded in >60% of patients in all 20 items for THA and 17 of 19 items for TKA. In THA, items with the largest proportions patients with unfulfilled expectations (>30%) were "improvement in walking ability: long distances" (31%), "walking stairs" (33%), and "improve ability to cut toenails" (38%). In TKA, expectations for 12 of 19 items were unfulfilled in >30% of patients, with the largest proportions seen for "being able to kneel down" (44%) and "being able to squat" (47%).ConclusionAlthough for most items, >60% of THA and TKA patients indicated that their expectations were met or exceeded, there was a substantial number of patients, particularly TKA patients, having unfulfilled expectations. These need more attention in preoperative patient information and education.Copyright © 2016 Elsevier Inc. All rights reserved.
