Cofield and Daly report outcomes of a chromium-cobalt, porous-coated cementless glenoid component paired with a Neer humeral prosthesis in 32 total shoulder arthroplasties, asking whether uncemented tissue-ingrowth fixation can match cemented glenoid performance over a mean 4+ year follow-up.
When planning cementless total shoulder arthroplasty, adequate glenoid bone stock and achieving intraoperative joint stability are non-negotiable — this series demonstrates that subluxation after surgery drives the majority of glenoid component failures, and that if a firm interference fit cannot be obtained at the time of implantation, conversion to cement is warranted.
