Event or Problem Description
As reported, approximately ten months post initial tka, this male patient had a revision for loosening femoral component.No additional information available.
Additional Manufacturer Narrative
After further review of additional information received the following sections d4, g3, g6, h2, h3, h4 and h6 have been updated accordingly.(h3) the revision reported was likely the result of an insufficient bond between the femoral component and the bone, which led to aseptic (non-infected) femoral loosening.The most probable root cause associated with the reported event of "loosening - femoral" is associated with weakened integration of the femoral component at the bone-implant interface due to loss of fibrous and/or bony tissue and leading to compromised anchorage of the device.
