Systematic review demonstrates improved outcomes and lower revision rates with bone grafting in primary versus revision shoulder arthroplasty, highlighting elevated risks during revisions.
PURPOSE: We performed a systematic review of the studies including clinical/functional outcomes and complications of bone grafting for glenoid defects in reverse total shoulder arthroplasty (RTSA). METHODS: The PubMed and Cochrane databases were searched for relevant papers. RESULTS: Thirteen articles were included. The mean clinical/functional subjective scores significantly improved postoperatively. The implant revision rate for primary and revision RTSA was 3.1% and 21.1% respectively. The reoperation rate was 3.5% and 24.4% respectively. CONCLUSIONS: There was moderate evidence that bone grafting is effective for glenoid defects in primary RTSA. Further high-quality research is required about revision RTSA for moderate-to-severe glenoid defects.
