Return to sports and physical work after anatomical and reverse shoulder arthroplasty

Background No consensus has been reached on the return to sports or physical work after shoulder arthroplasty due to a shortage of literature. The purpose of this study was to investigate return to sports or physical work after anatomical total shoulder arthroplasty (aTSA) and reverse shoulder arthroplasty (RSA), as well as the clinical and radiographic outcomes. Methods The inclusion criteria were as follows: 1) aTSA or RSA between 2012 and 2017, and 2) patients who preoperatively participated in sports or physical work. The exclusion criteria were as follows: 1) revision arthroplasty, 2) fracture/dislocation, 3) fracture sequelae, 4) postinfection, and 5) <2-year follow-up. Sports and physical work were classified as low-, medium-, or high-load activities. Range of motion, Constant score, sport or work return, and radiographic findings were evaluated and compared between aTSA and RSA groups. Results The subjects who met the criteria were 90 shoulders in 86 patients. The aTSA group consisted of 30 shoulders (10 men and 20 women) with a mean age of 71 ± 8 years (range, 56-85). The RSA group consisted of 60 shoulders (39 men and 21 women) with a mean age of 72 ± 6 years (range, 56-83). Active range of motion significantly improved after surgery in all directions in the aTSA group but only in flexion and external rotation in the RSA group. Postoperative external and internal rotations, as well as postoperative Constant scores and satisfaction, were significantly better in the aTSA than in the RSA group. In the aTSA group, the return rate was 93%, and the complete return rate was 70%. In the RSA group, the return rate was 83%, and the complete return rate was 30%. The complete return rate was significantly higher in the aTSA than in the RSA group. Only one aTSA shoulder showed loosening of the glenoid implant, and 8 RSA shoulders demonstrated low-grade scapular notching. Conclusion The return to sports or physical work rates after aTSA and RSA were high; however, the complete return rates were significantly higher in the aTSA group than in the RSA group. No radiographic failures were identified except for one asymptomatic glenoid loosening with a midterm follow-up.
