Glenohumeral arthritis is a degenerative disease of the shoulder joint. When the rotator cuff is intact there is limited evidence in existing literature in superiority of outcomes between total shoulder arthroplasty (TSA) and hemiarthroplasty (HA). The purpose of this systematic review was to compare patient reported outcome measures (PROMs) and rate of complication between these two interventions in patients with primary glenohumeral arthritis and an intact rotator cuff. Previous systematic reviews have focused on only results from randomized controlled trials, demonstrating mixed outcomes in PROMs and no difference in postoperative complications or rate of revision. Our study is the first, to our knowledge, to assess all comparative studies including prospective and retrospective observational studies, assessing a combined 1317 patients. Using the ratio of means, data from different PROMs was pooled to analyze and compare the total combined relative effect change following intervention.
We undertook literature review of the reference databases until March 2021. We included randomized controlled trials in addition to comparative observational studies and case series (more than 10 patients). Study participants were adults suffering from primary glenohumeral arthritis with an intact rotator cuff. Meta-analysis was performed by the ratio of means for PROMs and risk ratio for revision and complication data.
