The aim of this correlational study was to examine patients’ expectations to postoperative outcomes among older adults undergoing total knee arthroplasty and its related factors. The eighty-four older adults whose ages were sixty and over with severe knee osteoarthritis scheduled for total knee replacement surgery were enrolled. Before getting surgery, participants were asked to complete the Demographic and Health Information Questionnaire; the Knee Injury and Osteoarthritis Outcome Score (KOOS ADL); and the Hospital for Special Surgery Knee Replacement Expectations Survey (HSS-Knee Survey). Data were analyzed using descriptive statistics, independent t-test, and Pearson product moment correlation coefficient.
The results showed that the participants had a high level of postoperative outcome expectation score (M= 69.41, SD=13.87). When considering each item of their expectations, “regaining walking ability in a short distance” (M=3.69, SD=.51) and “improving psychological well-being" were highly expected (M=3.63, SD=.62). However, “improving sexual activity” (M=.55, SD=1.17) and “being employed for monetary reimbursement” (M=.68, SD=1.38) were the least of expectations. The participants with the difference in gender and preoperative functional ability had significant differences in postoperative outcome expectation score (t=3.363, p=.001 and t=3.911, p=.000, respectively). Moreover, gender and preoperative functional ability were only two factors significantly related to patients’ expectations (rbi=-.348, p=.001 and rp=.382, p=.000 respectively). The study highlights basic information for the healthcare team to understand patients’ expectation after receiving total knee arthroplasty and to design any intervention that could be resulting in patients’ expectation satisfaction and the desired surgical outcomes.
