China NMPA Product Recall - Modular Total Knee System

The National Medical Products Administration (NMPA) in China announced a Class II voluntary recall by Bangmei (Shanghai) Trading Co., Ltd., on September 28, 2016. This recall, initiated by manufacturer Biomet Orthopedics (also referred to as Zimmer Biomet), concerned specific batches of their Component-Type Total Knee Joint System, identified by National Medical Device Registration Certificate No. 20153462419. The primary issue involved the tibial pad bolts for the modular Vnaguard 360 total knee system. An investigation revealed that the drill bit used for creating the internal hexagonal socket of these bolt heads might exceed acceptable tolerance levels. This manufacturing deviation could prevent the bolts from being fully tightened, posing a potential risk to the stability of the knee joint prosthesis, which is intended for cemented knee replacement revision surgery. Despite the manufacturing defect, it was confirmed that zero affected products were sold within China, and no domestic complaints, adverse events, or deaths related to this issue have been reported. As a corrective action, all remaining frozen inventory of the implicated products was returned to the manufacturer, Biomet Orthopedics, as detailed in the Medical Device Recall Event Report Form dated August 12, 2016. This proactive measure ensures patient safety by preventing potentially faulty devices from reaching the market.
