Lonergan TM, et al. - After primary anatomic total shoulder arthroplasty (TSA), the impact of mood disorders on pain, narcotic use, and length of hospital stay, as well as complications, was studied among 133 primary anatomic TSA cases. Investigators included 29 cases (32 shoulders) out of the 133 with mood disorders. No significant differences between groups concerning age, operative indication, body mass index (BMI), or comorbidities were recorded. They did not find significant differences in visual analog pain scores or oral morphine equivalents narcotic use at any of the recorded time points. No statistically significant differences were estimated in length of hospital stay or postoperative complications. The postoperative course for TSA patients with a mood disorder and TSA patients without depression or anxiety seem to be similar.
