Johnson & Johnson’s own internal review of the hip implant known as the Articular Surface Replacement, or ASR, indicates that approximately 40% of the implants would fail within the first five years of implantation. Johnson & Johnson recalled the troubled hip implant in mid- 2010, yet did not release their internal analysis until after the recall.
The ASR recall is one of the largest medical device failures in years and raises questions as to what the managers of the DePuy Orthopedics Division of Johnson & Johnson knew about the hip implant’s problems before the implant was recalled. The ASR hip implant uses both a cup and ball component made of metal. Over time the grinding of the metal-on-metal device tends to produce metallic debris which damages the surrounding bone and tissue.
About 93,000 patients worldwide have received the Johnson & Johnson ASR. More than 30,000 of those patients are in the United States. Seven thousand ASR lawsuits have been consolidated in a federal court in Ohio and an additional 2,000 claims have been consolidated in a California state court action.
