The company informs that despite the low potential risk of this LPDE enclosure adhere to the polished surfaces, the manufacturer Zimmer Biomet is collecting the potentially affected products remaining in the stock. The company concluded that the adhesion of the LPDE bag is unlikely to cause a detrimental effect on the patient or the function of the implant. This conclusion is based on the following considerations: 1. LDPE material is biocompatible, similar to ultra high molecular weight polyethylene (UHMWPE). /// 2. LPDE is less hard than the two UHMWPE and cobalt-chromium molybdenum combination materials and therefore, no additional damage or wear is expected on the implant surfaces. /// 3. If there are wear particles generated from the adhered LDPE film or shell residue, similar biological reactions would be expected with those of UHMWPE that do not increase the likelihood of peri-prosthesis osteolysis.
