Abstract: Introduction-Aim: Reverse shoulder arthroplasty (RSA) is a valid option for several degenerative conditions of the shoulder. This study aimed to analyze mid-term functional outcomes and complications rates of cementless stem. METHODS: From January 2016 to December 2020, retrospective review of cementless RSA for degenerative conditions was established. Clinical outcomes were assessed using visual analog scale (VAS), University of California Los Angeles (UCLA) score, Constant score and range of motion (ROM). Radiographic findings were evaluated during follow-up. Complications rates was reported. RESULTS: At mid-term follow up of 39 months, 40 shoulders were included with sex-ratio= 0.53 Mean age was 67.7 years (60 -82). VAS score improved from 5.0 to 2.2 (p = 0.014). UCLA score increased from 17.2 to 25.7 (p = 0.002) and Constant score improved from 31.89 to 70.2 (p < 0.001). Active anterior elevation, abduction, and external rotation showed enhancement respectively 80° to 141.2°, 71° to 132.2° and 5.8° to 19.7° (p values < <0.0001). The mean calcar filling ratio was 0.86 (0.32 - 1.17 +/- 0.22). The mean proximal and distal filling ratios were 0.62 (0.48 - 0.73 +/- 0.06) and 0.56 (0.36 - 0.71 +/- 0.09) respectively. The overall rate of postoperative complications was 22.5%. CONCLUSION: Cementless stem improve functional outcomes at mid-term follow up. Stems were correctly aligned with the humeral axis and canal filling ratios were <0.7 in all cases. Stress-shielding was slightly higher without impact on clinical outcomes.
