Early to midterm outcomes of anatomic shoulder arthroplasty performed on dysplastic glenoids

BackgroundTreatment of primary osteoarthritis with glenoid dysplasia or Walch type C glenoids remains controversial. There is scant literature available on patient outcomes after anatomic shoulder arthroplasty in patients glenoids. The purpose this study was to evaluate the total (TSA) for dysplastic standard (nonaugmented) components compared TSA concentric wear and minimal erosion (Walch A1). We hypothesized that performed can reliably produce successful results at short- midterm follow-up.MethodsWe identified all who had a prospective registry collected from 2004 present time. Twenty-nine met inclusion criteria preoperative glenoid, treatment using components, minimum 2-year clinical follow-up. A matched cohort 58 A1 follow-up served as control group. American Shoulder Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), satisfaction, complications, revisions were evaluated both cohorts.ResultsThe mean 4.5 years (standard deviation, 2.6 years; range, 2-10 years). Baseline measures not significantly different between group (all P > .05).
