a Data are presented as mean ± SD (median). Boldface P values indicate a statistically significant difference between groups or time points (P < .05). ASES, American Shoulder and Elbow Surgeons; CMS, Constant-Murley score; postop, postoperatively; Preop, preoperatively; VAS, visual analog scale.
b Mann-Whitney U test for VAS pain; Student t test for CMS and ASES.
c Friedman test for VAS pain; repeated-measures analysis of variance for CMS and ASES.
