 Papers and Topic Sentences

Extensively Porous-Coated Femoral Revision for Severe Femoral Bone Loss: Minimum Ten-Year Follow-up (Podium No. 195)

Revision with an extensively porous-coated femoral component is an effective long-term reconstructive technique for patients with extensive femoral bone loss. Abstract

In Vivo Deterioration of Baseplate Locking Mechanisms in Modular Knee Implants (Podium No. 24)

Back to top

This study shows that locking mechanism stability deteriorates in vivo, thereby increasing motion at the insert-baseplate interface and creating debris.

Abstract

The Accuracy & Reproducibility of Radiographically Assessing Stress Shielding: A Postmortem Analysis (Podium)

Back to top

 Based on this study, we question radiographic evaluation of periprostheitc bone resorption, since it is not reproducibly recognized until 70% of bone is lost.

Abstract

Revision of Failed Unicompartmental Knee Arthroplasty (Podium #185)

Back to top

This paper evaluates the outcome of revision surgery for failed unicompartmental arthroplasties.

Abstract

Posters

A Single Center's Experience with Total Hip Arthroplasty Using Porous-Coated Acetabular Components (Poster #PE399)

Back to top

Acetabular component fixation employing a porous-coated surface has demonstrated excellent long-term integrity among a variety of hemispheric cup designs.

Summary and photos

Comparison Between Wear Measured Radiographically and Wear Measured from Explanted Polyethylene Liners: The Effect of Multiple Deformation Vectors (Poster)

Back to top

Unlike cups with a single deformation vector, radiographic measurements from cups with multiple deformation vectors.

 

Comparison of 3 Computer-Assisted Wear Measurement Systems on Optimal and Suboptimal X-rays (Poster)

Back to top

This study demonstrates the susceptibility of computer-assisted head penetration measurements to radiographic technique.

Abstract

Correlation Between Tibial Baseplate Wear and Locking Mechanism Micromotion in Modular Knee Implants (Poster #PE415)

Back to top

Locking mechanism instability heightened wear of modular tibial baseplates, there generating additional wear debris that could contribute to osteolysis.

 

Ten-Year Outcome of THA with Cementless Components Among Patinets with Developmental Hip Dysplasia (Poster #PE398)

Back to top

 This study demonstrated the ability of femoral head grafts to augment superior acetabular coverage and to maintain their structural integrity at 10-year follow-up. Distal osteolysis among the modular SROM stems was a concern. Based on the excellent clinical results achieved with extensively porous-coated femoral components, the authors continue to use them among patients with DDH.

The Effect of Knee Alignment on the Outcome of Unicompartmental Knee Arthroplasty (Poster #PE454)

Back to top

This poster presents a study evaluating the effect of knee alignment on the outcome of unicompartmental knee arthroplasty.
