Values are presented as mean ± standard deviation.
ASES: American Shoulder and Elbow Surgeons, VAS: visual analog scale, SANE: Single Assessment Numeric Evaluation, FF: forward flexion, ER: external rotation, IR: internal rotation, SNA: scapular neck angle, PSNA: prosthesis-scapular neck angle, PGRD: peg rim glenoid distance, SBOD: sphere bone overhang distance.
*Significantly different between the two groups.
