As part of the post-market surveillance activities, the firm recently received and analyzed new data regarding the ASR platform which suggests a higher than expected revision rate for the ASR XL Monoblock Metal-on-Metal (MoM) System linked to usage of monoblock MoM cups with corresponding head sizes below 50mm in diameter. As a result of the findings, DePuy Orthopaedics issued a Field Safety Notice to share the new data with the surgeons and reiterate the importance of correct implant positioning and patient selection in achieving optimal implant performance and survivorship.”
