Zirconia-Toughened Alumina Ceramic Wear Particles Do Not Elicit Inflammatory Responses in Human Macrophages Open
Ten percent of patients undergoing total hip arthroplasty (THA) require revision surgery. One of the reasons for THA are wear particles released from the implants that can activate the immune defense and cause osteolysis and failure of the…

Is Surface Metastability of Today’s Ceramic Bearings a Clinical Issue? Open
Recent studies on zirconia-toughened alumina (ZTA) evidenced that in vivo aged implants display a much higher monoclinic zirconia content than expected from in vitro simulations by autoclaving. At the moment, there is no agreement on the s…

Implant Material As A Modifiable Risk Factor For Infection In THA: A Literature And Registry Review Open
Aim: Periprosthetic Joint Infection (PJI) is a rare but serious post-operative complication of hip replacement that often ends in complex implant revision and dramatically impacts the quality of life of the patient. Finally, costs associat…
