Tissue Damage from Metal-on-Metal Hip Replacements Occurs before Symptoms Show

The absence of pain does not necessarily indicate an absence of damage when it comes to hip implants, according to a new study set to be published in an upcoming issue of the Journal of Bone & Joint Surgery.

About the Metal-on-Metal Hip Implant Study

“The study shows that synovitis exists in asymptomatic people in a fairly high prevalence.” – Hollis Potter, M.D., chief of the Division of Magnetic Resonance Imaging at the Hospital for Special Surgery as published by Science Daily

Researchers at the Hospital for Special Surgery have found that tissue damage caused by defective metal-on-metal hip implants occurs before symptoms appear.

According to Science Daily, the researchers were interested in evaluating the possibility of using magnetic resonance imaging (MRI) to identify adverse events in both symptomatic and asymptomatic metal-on-metal hip replacement patients.

Not only did the researchers find that MRI could be used to accurately identify tissue inflammation associated with hip implant defects, but that synovitis (inflammation of the membrane that lines the synovial joints) had occurred in 68 percent of asymptomatic patients.

Further, the researchers were able to positively identify synovitis in 68 percent of patients who displayed no symptoms in connection to their implants and in 78 percent of patients who had complained of unexplained hip pain.

Defective DePuy Metal-on-Metal Implants

  • Johnson & Johnson is currently facing thousands of lawsuits in connection to inflammation, tissue necrosis and ruptured tendons attributed to their DePuy metal-on-metal hip implants.
  • While the company is currently awaiting approval on a $2.5 billion proposal that would settle roughly 7,500 lawsuits linked to its ASR implants, the company is facing an additional 4,000 lawsuits tied to its Pinnacle implant system which are set to begin in the fall.
  • According to reports, friction between the metal joint and metal socket of the metal-on-metal implants results in the device shedding metal fragments which damage the surrounding tissue or enter the blood stream.
  • Originally designed to extend the time a hip implant would last before failing, previously 15 years, experts now estimate that the metal-on-metal options are prone to failure within 5 years.
