Abstract: Total hip arthroplasty (THA) has been performed for nearly 50 years. Between 2006 and 2012, more than 600,000 metal-on-metal THA procedures were performed in the United States. This article reviews the production of metal wear debris in a metal-on-metal articulation and the interaction of cobalt and chromium ions that ultimately led to a dramatic decline in the use of metal-on-metal THA articulations. Additionally, the article reviews mechanisms of metal wear, … Read the Rest
The survivorship of total hip arthroplasty in younger patients is dependent on the wear characteristics of the bearing surfaces. Long-term results with conventional polyethylene in young patients show a high failure rate. This study assessed the long-term results of a first-generation annealed highly cross-linked polyethylene (HCLPE) in uncemented total hip arthroplasty in young, active patients…
…The current study found no significant oxidation effect or polyethylene wear that would cause adverse clinical … Read the Rest

Nine surgeons with 11 years and 1,100 ceramic-hip experience have never heard a squeak…
…What is more interesting is the severity and frequency of the squeaking. We have seven surgeons who have used the Accolade/Trident implant combination, and all seven have heard squeaking in their office. We have nine surgeons with more than 10.5 years experience with 1,100 hips with flush-mounted liners and none … Read the Rest
I have a Stryker ceramic and titanium hip replacement and have had it since 10/2/03 I first noticed the squeak while making love, it worsened: and going up stairs is actually quite noisy.
