Table 2 Summary of measured values (mean and standard deviation) grouped by surgeon’s experience. (β) pelvic inclination measured during patient preparation, (Θ) cup inclination measured postoperatively, (LLD) leg length discrepancy measured posoperatively. Statistical significance p between measured values in different groups obtained from Kruskal-Wallis test (β and LLD) and ANOVA test (Θ).
