Clinical and radiographic outcomes of an all-polyethylene fluted central peg glenoid component, implanted utilizing an off-label, uncemented technique, at a minimum 5-year follow-up.

Background: Glenoid component loosening remains an important concern in anatomic total shoulder arthroplasty. The aim of this study was to evaluate the clinical and radiographic results of a fully uncemented all-polyethylene fluted central peg bone-ingrowth glenoid component at a minimum 5-year follow-up.

Methods: Thirty-five shoulders in 31 patients (mean age, 73 years) with a mean follow-up of 100 months were retrospectively evaluated at an early and mid-term time point for Constant score (CS).

Fully uncemented glenoid component in total shoulder arthroplasty.

Background: Loosening of the glenoid component remains the most common problem in total shoulder arthroplasty. It has been described that the round-backed, all-polyethylene components with cemented peg fixation perform better biomechanically and clinically than flat-backed, metal-backed, or keeled components. However, side effects of cementing have been described.

Total ankle replacement outcome in low volume centers: short-term followup.

Background: The indication for total ankle replacement (TAR) as an alternative to ankle fusion continues to be a much-debated topic. The reported survival of TAR at midterm followup is approximately 90%. The aim of this study was to compare functional outcome and survival of TAR in low volume centers versus high volume centers.
