Manufacturer Narrative
Reported event: an event regarding loosening involving an unknown gmrs baseplate was reported.The event was confirmed via evaluation of the provided medical records.Method & results: -product evaluation and results: material analysis, visual, functional and dimensional inspections could not be performed as the device was not returned.-clinician review: a review of the provided medical records by a clinical consultant stated the following comment: i have had the opportunity to review documentation related to 2 pi's including the product inquiry summaries, as well as multiple radiographs from august 11, 2022 including ap, and lateral views of a revision gmrs tka with proximally replacing tibial and distal femoral replacing hinge components.In addition an operative report from august 27, 2018 describing a revision surgery resection of the proximal tibia for recurrent giant cell tumor and implantation of the gmrs knee.And a clinic note from august 11, 2022 were reviewed.The x-rays show a gmrs tka with proximally replacing tibial and distal femoral replacing hinge components with cemented stem.There are subtle lucencies around the stem indicating possible early loosening.In addition, there are calcifications at the tip of the stem consistent with stress reaction.The clinic note states that the patient had initially done quite well but 2 months prior to the visit to the clinic had gone an extensive walk and subsequently developed unrelenting significant startup pain limiting her activities.Revision surgery for tibial loosening as a result of recurrent giant cell tumor in the proximal tibia is confirmed as is anterior tibial pain.There are radiographic findings consistent with stress reaction of about the tip of the cemented tibial stem as well as lucencies suggestive of possible early loosening.The root cause of this pain and possible mechanical failure cannot be determined from this limited documentation.Should additional information become available i would be happy to further this assessment.-product history review: could not be performed as the device lot details were not provided.-complaint history review: could not be performed as the device lot details were not provided.Conclusions: should additional information become available i would be happy to further this assessment.No further investigation for this event is possible at this time.If additional information become available to indicate further evaluation is warranted, this record will be reopened.
