Neyton L, et al. - Through a retrospective multicenter study performed on 202 patients aged 60 years or less who underwent either hemiarthroplasty (HA) or total shoulder arthroplasty (TSA) for primary glenohumeral osteoarthritis, the researchers intended to determine the outcomes of shoulder arthroplasty in young patients with primary glenohumeral osteoarthritis. A significantly better range of motion, pain, subjective shoulder value, and constant score in young patients when compared with HA was noted as a result of TSA with no important difference in longitudinal survivorship in comparison with patients treated with HA was observed.
