Polyethylene wear: an under-reported cause of failed shoulder arthroplasty

Surgeons should be aware of the possible sequelae of PE wear in patients after shoulder arthroplasty, especially those with conventional, noncrosslinked PE. New onset pain and weakness after a symptom-free holiday (years) are common after aTSA. New onset instability and pain after a symptom-free holiday (years) are common after rTSA. Radiographic findings can include humeral and glenoid bone loss, a narrowed glenoid clear space, and eccentricity of the articulation. The diagnosis is provisionally made and confirmed intraoperatively. Revision poses unique challenges and should include aggressive synovectomy, débridement, and individualized bone loss management. Further studies are crucial for understanding this emerging phenomenon after shoulder arthroplasty.
