Background Failure rates of constrained cups for treating recurrent dislocation in revision
THA range from 40% to 100%. Although constrained liners are intended to stabilize the hip …

We analysed data from 155 revisions of identical cementless hip prostheses to determine
the influence of patient-, implant-and surgery-related factors on the polyethylene wear rate …

Wear of UHMWPE acetabular components is the most serious threat to the long-term
success of hip replacements. Consequently numerical and experimental wear simulations …

In hip replacement the use of hard bearing materials, which have been shown to have lower
wear rates than traditional metal-UHMWPE couples, has been encouraged in an effort to …

Total hip arthroplasty has yielded excellent results in decreasing pain and enhancing
function in patients with hip degenerative disease. However, the problems associated with …

Background Aseptic loosening remains a challenging problem after total hip arthroplasty.
Accurate cup placement and supplementation of antioxidants in acetabular liners might …

Introduction Glenoid component wear and loosening is the Achilles heel of total shoulder
replacement. Analysis of failed, revised implants might give an insight into the causes of …

BACKGROUND Polyethylene (PE) particles produced by wear of the acetabular insert are
thought to cause osteolysis and thereby aseptic loosening of the implant in total hip …

Because of their unique geometry, characterization of wear damage in total disc
replacement (TDR) is difficult. In the article, we developed and validated an automated …

The purpose of this study was to evaluate the reliability of the PowerPoint (PP)(2007
Version; Microsoft, Redmond, Wash) method for measuring polyethylene liner wear after …
