The Medicines and Healthcare products Regulatory Agency (MHRA) has identified increased risks of wear and corrosion associated with specific cobalt-chrome modular neck hip replacements. NHS trusts are advised to identify patients with devices from Aesculap AG, LimaCorporate, Smith and Nephew, Stryker, or Symbios and offer clinical reviews. These implants, no longer available in the UK since 2019, were used between 2007 and 2019, with around 750 patients currently implanted. While most patients experience no serious issues, some may face tissue reactions requiring revision surgery. Patients experiencing new symptoms should consult their surgeon or report concerns via the MHRA’s Yellow Card scheme. The review followed a 2025 assessment of similar devices and found varied revision rates across systems, though no elevated fracture risks were detected.
