Anatomic shoulder arthroplasty: the correlation between patient resilience, mental health, and outcome

Recovery from anatomic shoulder arthroplasty may be enhanced in patients with good mental health and the resilience to participate in the prescribed postoperative rehabilitation program. To test this concept, we utilized validated and reliable scales in determining whether resilience and mental health are associated with the outcome of anatomic arthroplasty. Three hundred ninety-nine patients (195 ream and run [RnR] and 204 anatomic total shoulder arthroplasty [aTSA]) were surveyed at a mean follow-up of 6.3 ± 3.3 years. Preoperative variables included age, sex, body mass index, history of prior shoulder surgery, diabetes, visual analog scale for pain, Simple Shoulder Test (SST) scores, and Veteran's RAND 12 Mental Component Score (VR-12 MCS). Outcomes collected included the SST, American Shoulder and Elbow Surgeons (ASES) score, revision rate, and patient satisfaction. Resilience was documented using the Connor-Davidson Resilience Scale 10 (CD-RISC 10) at latest follow-up. Univariable and multivariable regression analyses were used to identify factors significantly associated with follow-up postoperative SST, ASES, and satisfaction. In the univariable analysis, CD-RISC 10 was positively correlated with postoperative SST, ASES, and satisfaction after both RnR and aTSA. The mean CD-RISC 10 scores were higher in the RnR cohort (34.3 ± 4.8 vs. 32.5 ± 6.2 for aTSA, P
