Effectiveness of Blended Instruction on Pain and Requirement for Analgesic after Knee Arthroplasty Surgery

Background and aims: Most patients undergoing knee replacement surgery have pain and limited range of motion during recovery and rehabilitation and due to pain and lack of experience and knowledge are not able to run an effective rehabilitation program. So, this study was aimed to determine the effect of blended instruction on the intensity and the admission palliative of patients undergoing knee surgery. Methods: 64 patients scheduled for knee replacement surgery randomized block Foursome assigned to two experimental and control groups. The training program including film screenings and providing face to face training, manual and training video in the individual manner was implemented days before the surgery for the experimental group. The control group received routine care. Data by demographic and clinical form and pain assessment checklist were collected using a visual analogue scale. Numerical data about the pain from the second to fifth days and one month after surgery were collected and analyzed useing the SPSS software and Independent t-test, Chi-square and Repeated measure tests. Results: The results of this study showed that the experimental group reported significantly less pain than the control group at most times (P=0.012). According to independent t-test statistically significant difference between the 2 groups in terms of the amount of admission palliative at the time was found (P>0.054). However, based on analysis of variance with repeated measures between the admission palliative on study, there was a significant difference in both groups (P<0.001). Conclusion: According to our results, the combined intervention before surgery can reduce the level of pain experienced after surgery and as a training method used to teach these patients after surgery
