Abstract

Background

The younger patient with glenohumeral arthritis presents a challenge because of concerns about activity and frequency of failure. The purpose of this study was to define the results, complications, and frequency of revision surgery in this group.

Materials and Methods

Between 1986 and 2005, 46 total shoulder arthroplasties and 20 hemiarthroplasties were performed in 63 patients who were aged 55   years or younger and had chronic shoulder pain due to glenohumeral osteoarthritis. All 63 patients had complete preoperative evaluation, operative records, and minimum 2-year follow-up (mean, 7.0   years) or follow-up until revision.

Results

Nine shoulders underwent a revision operation. The implant survival rate was 92% (95% confidence interval, 77%-100%) at 10   years for total shoulder arthroplasty and 72% (95% confidence interval, 54%-97%) for hemiarthroplasty (Kaplan-Meier result). Patients who underwent total shoulder arthroplasty had less pain (P = .01), greater active elevation (P = .05), and higher satisfaction (P
