As reported, approximately 3 years and 5 months post left total knee arthroplasty (tka), revision of the prosthesis was performed due to wear on the patella and tibial insert as well as the femur ¿debonded¿ from the cement.Everything was removed and replaced with a competitor prosthetic.There was no reported breakage of the device and no surgical delay/prolongation.The patient was last known to be in stable condition following the event.

Report numbers: 1038671-2024-04045, 1038671-2024-04047 this follow-up report is being submitted to relay additional and/or corrected information.The product associated with the reported event is within the scope of recall z-0021-2022; however, there is insufficient information to evaluate whether the subject issue of the recall was a cause or contributor to the reported event.The following sections were corrected: b2 d10 concomitant: 1069721095 a10012 - gps implant kit v2, 1076421014 a10012 - gps implant kit v2, 6556906 02-012-45-2525 - lgc tibial fit tray cem sz 2.5f / 5t, 6837180 201-78-81 - 3 trocar, mod.Hex 2pk, 6872961 201-78-15 - holding pin mini sharp point 4 pk, s007833 521-78-32 - threaded pin size 3.0 collarless, s058427 02-012-51-2509 - logic tib insert impl crc, sz 2.5, 9mm, s084448 521-78-23 - threaded pin size 2.3 collared, s084460 521-78-23 - threaded pin size 2.3 collared.The revision reported may have been the result of prosthesis wear and femoral loosening, as stated in the experience report.However, the images of the revised tibial insert do not show signs of extensive wear inconsistent with being implanted for over 3 years.The aseptic (non-infected) loosening of the femoral component may have been due to an insufficient bond at the cement-implant interface.However, potential contributions of user or patient-related considerations to the event could not be assessed as the devices were not returned for evaluation, and no relevant clinical information, radiographs, or images of the patella component were provided.If any further information is obtained that would change or alter any information provided, a supplemental report will be filed accordingly.
