TL;DR: The growth rates of upper extremity arthroplasty were comparable to or higher than rates for total hip and knee procedures, and of particular concern was the increased revision burden.

TL;DR: The purpose of this study was to investigate the reasons for revision and to assess the amount of bone ingrowth in retrieved porous tantalum components, and to observe full depth penetration of bone into the porous tantalu layer for the acetabular shells and femoral stems.

TL;DR: Rim damage was the predominant cause of polyethylene wear in 7 specimens retrieved at revision arthroplasty and direct contact between the humeral component and inferior metaglene screws is concerning because this could lead to accelerated ultra-highmolecular weight poly methylene wear and also induce mechanical loosening of the glenoid component.

TL;DR: In this study, no correlation was observed between the taper angle clearance and the visual fretting-corrosion scores in either the ceramic or the metal cohorts.

TL;DR: RSA is performed with similar frequency to TSA and almost twice as much as SHA in the Medicare population and lower-volume surgeons perform most RSAs, and a majority of surgeons perform more RSAs than all anatomic shoulder arthroplasties combined.
