Our study findings demonstrated that the modified McLaughlin procedure showed good results over a 2-year minimum follow-up period. The clinical outcomes of this procedure are worse when there is a delay from injury to diagnosis > 6 months. 6 months. The role of the subscapularis in reverse shoulder arthroplasty (RSA) remains controversial. Studies had shown that subscapularis repair has no significant influence on the functional outcome of patients. However, few studies have assessed the postoperative integrity of the subscapularis tendon after RSA. The aim of the current study is to investigate the postoperative healing of the subscapularis after RSA via ultrasound and to evaluate the relationship between tendon integrity and functional outcomes. We hypothesized that subjects with healed subscapularis after RSA would yield higher Constant scores and better internal rotation (IR) compared to those without a healed subscapularis. This is a retrospective review of all patients who underwent primary RSA with subscapularis tenotomy repair performed by a single surgeon with a minimum 2-year follow-up. Inclusion criteria were (1) primary RSA; and (2) complete intraoperative repair of the subscapularis tenotomy if tendon was amenable to repair. Total Constaference in external rotation (p <0.01). The healing rate of the subscapularis following RSA was only 52.6%. IR function in patients with intact subscapularis at 2 years after RSA were significantly better than in patients with failed or absent tendon repairs. Primary repair of reparable subscapularis tendons during RSA should be strongly considered. The healing rate of the subscapularis following RSA was only 52.6%.
