China NMPA Product Recall - Unicompartmental knee joint system components

Biomet UK LTD., in conjunction with its distributor Zimmer Medical (Shanghai) International Medical Trading Co., Ltd., initiated a voluntary global recall for specific components of its Oxford Unicompartment Knee Joint System, notably the uncemented tibial type. This regulatory action, documented under National Medical Products Administration (NMPA) Index No. JGXX-2017-10407, was reported around May 2017. The primary concern arose from patient reports of tibial plateau fractures, with a worldwide incidence of 0.12%. Investigations confirmed that the product met design specifications, attributing the fractures primarily to the critical importance of adherence to specific surgical techniques and the product's instructions for use. While a global field safety notification was enacted, Biomet UK LTD. verified that the affected product batches were not distributed or sold within China, and consequently, no domestic adverse events or complaints have been recorded. The NMPA instructed provincial Food and Drug Administrations to enhance supervision over similar medical devices. The required action emphasizes strict compliance with established surgical protocols and product guidelines to minimize risks and ensure patient safety.
