*2.3. Statistical Analysis*

For statistical analysis, a comparison was made between the values originally collected postoperatively and those collected at the follow-up examination. If the Shapiro–Wilk test did not obtain a normal distribution, the Wilcoxon test for paired samples was used instead. We also used descriptive statistics for data evaluation. The data were evaluated and compared using Origin Pro® 9.0 (OriginLab Corp, Northampton, MA, USA) and SPSS® 26.0 software (IBM Corp, Armonk, NY, USA). OriginLab® was used to create a Kaplan– Meier plot for the endpoints defined as revision for conversion to RSA and revision for any reason. Furthermore, common statistical methods, such as the mean values, medians, effect sizes, ranges, and standard deviations (SDs), were used in this study.
