Update on Hard-on-hard Bearings in Hip Arthroplasty: Editorial Comment

SYMPOSIUM: UPDATE ON HARD-ON-HARD BEARINGS IN HIP ARTHROPLASTY Survival of Hard-on-Hard Bearings in Total Hip Arthroplasty

Background Improvements in prosthetic materials, designs, and implant fixation for THA have led to bearing surface wear being the limitation of this technology. Hardon-hard bearings promise decreased wear rates and increased survival. However, there may be different survival rates based on bearing materials, manufacturing technologies, and femoral component designs. Additionally, survival rate ...

SYMPOSIUM: UPDATE ON HARD-ON-HARD BEARINGS IN HIP ARTHROPLASTY Is Resurfacing Arthroplasty Appropriate for Posttraumatic Osteoarthritis?

Background High survival has been reported for resurfacing arthroplasty in patients with femoral deformities. Also, hardware removal may not always be necessary with resurfacing arthroplasty and may eliminate some of the difficulties performing total hip arthroplasty (THA) in patients with posttraumatic osteoarthritis. Questions/purposes We therefore asked: (1) are survivorship higher in patien...

SYMPOSIUM: UPDATE ON HARD-ON-HARD BEARINGS IN HIP ARTHROPLASTY Hip Resurfacing in Patients Who Have Osteonecrosis and are 25 Years or Under

Background Young patients with osteonecrosis (ON) treated with THA often have suboptimal function and radiographic failure with eventual revision. Resurfacing may be an option because of potentially increased functionality and decreased radiographic failure, although neither has been confirmed in the literature. Questions/purposes We therefore compared the clinical scores and radiographic failu...

Ceramic-on-ceramic bearings total hip arthroplasty in young patients

BACKGROUND The results of ceramic-on-ceramic (CoC) total hip arthroplasty (THA) in younger patients were not univocal. This study aims to evaluate the results of CoC bearing THA in patients younger than 50 years. METHODS A total of 90 younger patients performed CoC THAs during March 2003 and May 2008 were included in this study. Hip function and activity were evaluated with Harris hip score a...
