Early outcomes of shoulder arthroplasty according to sex
HYPOTHESIS: Among patients undergoing shoulder arthroplasty (SA), female patients would have worse outcomes than their male counterparts.
METHODS: A multicenter prospective cohort of 2364 patients (1365 female and 999 male patients) treated with total SA or reverse total SA from 2007 to 2015 was retrospectively analyzed. Results were assessed using several validated outcome measures and range-of-motion testing. A multivariable analysis identified differences in preoperative values, postoperative values, and preoperative-to-postoperative improvements while adjusting for possible confounders.
