FDA Approves New Depuy Hip Implant

On June 14, the FDA announced that it approved a new artificial hip system from DePuy Orthopaedics and Johnson & Johnson. The Pinnacle Complete Acetabular Hip System is the first ceramic-on-metal hip system approved by the FDA. Unlike the DePuy recalled hips, the new system features a ceramic ball in a metal socket. The ceramic-on-metal design may avoid the problems that plague metal-on-metal hip implants. The presence of ceramic may decrease the risk of metal debris since there is less grinding metal. However, ceramic-on-metal hip implants may not differ substantially from metal-on-metal implants.

A two-year research study showed no clinical difference between the new ceramic-on-metal hip replacement system and metal-on-metal implants. The study served as a basis for the FDA's approval decision, despite the hundreds of personal injury lawsuits that Johnson & Johnson faces for the damage caused by its metal-on-metal hip implants. Over 93,000 patients worldwide had FDA-approved DePuy defective hips implanted that were later recalled.
