Jacqueline Lum's attorneys allege that the replacement failed shortly after its implantation, causing significant pain and necessitating the imminent replacement of a year-old device intended to last up to 15 years.

Her attorneys also claim that irregularities in the device have resulted in the deposition of heavy metals like cobalt and chromium in Lum's bloodstream.
They further assert that DePuy Orthopedics was aware of its device's defects more than two years in advance of Lum's August 2009 surgery.
According to the news source, DePuy issued a worldwide recall of the faulty device in August 2010, stating that "...more people than expected who received the ASR hip system experienced pain and other symptoms that led to a second hip replacement surgery," although they went on to note that most recipients of the device reported no problems.
