China NMPA Product Recall - Acetabular cobalt-chromium-molybdenum alloy liner (trade name: R3)

The National Medical Products Administration (NMPA) published a voluntary recall initiated by Smith & Nephew, Inc. ASD Division for its R3 Acetabular Cobalt-Chromium-Molybdenum Alloy Liner, effective June 20, 2012. This action was prompted by a significantly higher-than-expected number of revision surgeries associated with the product, which is utilized in primary and revision total hip arthroplasty. The main issue identified was a potential risk of patient pain or restricted movement. Under the NMPA's regulatory guidance, provincial food and drug administrations were requested to strengthen supervision of this product type. The required actions included an immediate inspection of affected inventory, leading to the freezing of 52 boxes of the product. These affected units are to be returned from Smith & Nephew's Shanghai warehouse to its U.S. division for comprehensive recall processing, ensuring patient safety and product accountability.
