These procedures were grouped into 2 cohorts: all polyethylene-bearing glenoid components with either XLPE or non-XLPE. The cumulative percent revision was determined using Kaplan–Meier estimates of survivorship and hazard ratios from Cox proportional hazard models adjusted for age, sex, humeral head size, humeral fixation, type of primary (total stemmed or stemless anatomic), glenoid component type (modular and nonmodular metal-backed glenoid, cemented polyethylene glenoid, and polyethylene glenoid with modified central peg), and surgeon volume (after 2008).

The overall study population was 74% female, and the average age was 72.6 years (23-95). The most common diagnosis was cuff tear arthropathy [35.2%], followed by proximal humerus fracture [19.5%], and rotator cuff tears [14.9%]. Patient-reported outcome measures improved significantly when comparing preoperative and postoperative values. ROM, including forward elevation, abduction, and external rotation, also improved significantly postoperatively. The overall complication rate was 14.7% (n = 981). The most common complications were implant loosening (3.3%, n = 219) and instability or dislocation (3.3%, n = 218). The overall revision rate was 5.5% (n = 310). The device survivorship rate at a minimum of 5 years was 94%.</div></div><div><h3>Conclusion</h3><div>This systematic review demonstrated that outcomes of rTSA performed for a variety of shoulder pathologies demonstrate significant improvement in nearly all patient-reported outcome scores as well as significant improvement in ROM at long-term follow-up. The overall complication rate of 14.7% is relatively low, and the device survivorship is good at 94% at a minimum of 5 years.</div></div>","PeriodicalId":39885,"journal":{"name":"Seminars in Arthroplasty","volume":"34 4","pages":"Pages 953-963"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142748287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
