Abstract BACKGROUND: Total knee arthroplasty (TKA) can cause operational anxiety in patients. The
purpose of this study was to determine the effects of a hospital rehabilitation program on operational
anxiety in patients following TKA.
MATERIALS AND METHODS: A nonrandomized clinical trial was conducted on 96 patients who
were total knee replacement (TKR) candidates in Milad Hospital, Tehran, Iran. The participants
were allocated to two groups of control and experiment each with 48 participants. A rehabilitation
training program was implemented in the experimental group and the routine care program was
administered to the control group. The data collected through demographic form and Spielberger
anxiety questionnaire. The collected data were analyzed using Fisher’s exact test, covariance,
independent t‑test, and paired t‑test (P = 0.5).
RESULTS: The results of the paired t‑test indicated that the mean score of anxiety in both groups
was decreased. Independent t‑test showed that there was a significant difference between the two
groups in terms of the mean scores of anxiety so that it was significantly higher in the control group
compared to the experimental group (P < 0.001).
CONCLUSIONS: The implementation of the rehabilitation education by a rehab nurse can improve
the surgical outcomes in patients under TKR. Despite the positive results in this study, the results
should be interpreted and clinically used with caution given the small number of participants and the
specific circumstances of this study.
