Objective test results: a Surgery time: when performed as the first test, RRA-SST significantly shortened the surgery times for Crowe’s classifications III and IV; b Ideal rotator center discrepancy (IRCD): when performed as the first test, RRA-SST produced accurate IRCDs for Crowe’s classification III; c Inclination: when performed as the first test, the inclination of Group A for Crowe’s classification III and Group B for Crowe’s classifications II, III, and IV were not within the qualifying range, but the differences in inclination for Groups A and B for Crowe’s classification III were still statistically significant; d Anteversion: when performed as the first test, RRA-SST can make anteversion for Crowe’s classification III significantly better; e Number and constituent ratio of the ideal cup size discrepancy (ICSD): when performed as the first test, RRA-SST could increase the number of perfect and qualifying ICSDs and reduce the number of unqualified ICSDs
