The impact of mental health conditions on clinical and functional outcomes after shoulder arthroplasty: a systematic review.

BACKGROUND

Shoulder arthroplasty (SA) has been shown to improve quality of life, though outcomes may vary between individuals. Multiple factors may affect outcomes, including preoperative mental health conditions (MHCs). The goal of this systematic review was to evaluate the clinical and functional outcomes after SA in patients with MHC compared to patients without MHC.

METHODS

This systematic review was performed in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines outlined by Cochrane Collaboration. A search of PubMed, the Medline Library, and EMBASE was conducted from inception until September 2023 to obtain studies reporting outcomes after total shoulder arthroplasty and reverse total shoulder arthroplasty in patients with and without MHC. Study characteristics and information on clinical and functional outcomes were collected. All included studies were case-control studies. The methodological quality of the included primary studies was appraised using the methodological index for nonrandomized studies scoring.

RESULTS

Eleven articles published between 2016 and 2023 met inclusion criteria. In total, 49,187 patients, 49,289 shoulders, and five different MHC were included. 8134 patients in the cohort had a diagnosed MHC. The mean patient age was 67.8 years (range, 63.5-71.6 years), and 52.6% of the patients were female. The mean follow-up time was 35.5 months (range, 16.2-58.3 months). Reverse total shoulder arthroplasty was the most common type of procedure (25,543 shoulders, 51.8%). Depression and anxiety were the most reported psychiatric diagnoses (7990 patients, 98.2%). Patients with versus without MHC reported mean improvements of 38 and 42 in American Shoulder and Elbow Surgeons shoulder score and mean Visual Analog Scale pain improvements of 4.7 and 4.9, respectively. Mean complication rates of 31.4% and 14.2% were observed in patients with versus without MHC, respectively. The most prevalent surgical complication in patients with MHC was infection (1.8%), followed by prosthetic complication (1.7%), and adhesive capsulitis (1.6%).

CONCLUSIONS

Patients with MHC may have lower preoperative range of motion, worse postoperative shoulder function, and higher postoperative pain levels than patients without MHC. Patients with MHC demonstrated improvements in range of motion and functional outcomes after SA but had higher reported complication and revision rates when compared to patients without MHC. Depression and anxiety were the leading conditions correlated with lower outcomes in patients with MHC after SA. Preoperative physical therapy, mental health counseling, and expectation setting may help these patients reach the maximal achievable benefit from SA.
