%X <B>BACKGROUND: </B>The aim of this study was to compare outcomes and complications in patients with and without a history of prior rotator cuff surgery who underwent reverse total shoulder arthroplasty (RTSA).<BR><B>METHODS: </B>Two-hundred and nine consecutive patients who had undergone RTSA for rotator cuff insufficiency with a minimum 12-months follow-up period were reviewed. A total of 35 patients with a history of prior rotator cuff surgery were made the study group (PS group). Using propensity score matching for age and sex, these patients were matched 1:3 with a control group of 105 patients with no history of prior surgery (NPS group). The mean follow-up period was 41.4 months.<BR><B>RESULTS: </B>Both groups showed a significant improvement of clinical scores and range of motion after RTSA. The PS group showed a significantly higher final visual analog scale (VAS) pain score compared with the NPS group (P = 0.020). The PS group showed a significantly higher incidence of acromial stress fracture compared with the NPS group (17.1% vs 4.8%, P = 0.018), but no significant difference in the overall complication rate was observed (25.7% vs 13.3%, P > 0.05). The PS group showed a significantly higher reoperation rate compared with the NPS group (14.3% vs 1.9%, P = 0.004).<BR><B>CONCLUSIONS: </B>Our study demonstrated that a history of prior rotator cuff surgery was associated with a high incidence of acromial stress fracture and reoperation after RTSA as well as a high final VAS pain score, although satisfactory clinical outcomes after RTSA were achieved in both groups.
