The Effect of Showing Intraoperative Cartilage Damage and Post-Implantation Range of Motion Photos to Patients on Early Clinical and Functional Outcomes in Patients Undergoing Total Knee Arthroplasty Objective: The aim of this study is to determine the early clinical and functional effects of showing photos of intraoperative cartilage damage and range of motion after prosthetic implantation to patients who undergo Total Knee Arthroplasty as part of the treatment for advanced gonarthrosis (stage 3-4). Patients and Methods: The study was initiated at Bezmialem Vakıf University with approval from the Ethics Committee (Approval Number: E.167479) on 03.10.2024. With a 95% confidence level and 80% power (average difference of 4 units, standard deviation of 6.3), at least 40 patients per group (2 groups) are required. Data will be analyzed using IBM SPSS Statistics 22.0 software. The t-test will be used to compare the mean differences of continuous variables between groups, the Chi-square test will be used for the distribution of categorical variables between groups, and Pearson correlation coefficient will be used to analyze the relationship between continuous variables. Descriptive statistics will include mean, standard deviation, correlation coefficient (r), frequency, and percentage values. A p-value of \<0.05 will be considered statistically significant. Exclusion criteria for our study include revision total knee arthroplasty surgeries, total knee arthroplasty surgeries following high tibial osteotomy, total knee arthroplasty surgeries after unicompartmental knee arthroplasty, and surgeries with advanced deformities requiring the use of revision implants.
