Manufacturer Narrative

An event regarding tibial baseplate loosening in the right knee involving an unknown bone cement was reported. The event was confirmed. Method and results: device evaluation and results: not performed as the product was not returned. Medical records received and evaluation: development of radiolucent lines at 6-months is very early and as such points to a very severe inadequate cementation of the baseplate. This relates to surgical technique and has no relationship with either bone cement, that has standardized properties, or the tibial baseplate device that has a standard surface understructure to serve optimal cemented fixation. The surgeon is responsible for quality of cementation as part of his surgical technique. This loss of fixation below the medial baseplate section contributes to micro-motion between cement and bone where it is known that micro-motion causes bone resorption. This process causes a self-accelerating downward spiral of progressive micro-motion and further progressive bone loss as evident in the progressive subsidence of the baseplate until complaints were so severe that revision was required after only some 2-years of implantation. Baseplate only cementation is the principal root cause of failure to provide suboptimal baseplate fixation with rapid disintegration of implant-bone interface and device subsidence requiring revision. Completely procedure-related event with minor secondary contribution by the patient overweight condition. Device history review: not performed as no device details were provided. Complaint history review: not performed as no device details were provided. Conclusions: medical review indicated that baseplate only cementation is the principal root cause of failure to provide suboptimal baseplate fixation with rapid disintegration of implant-bone interface and device subsidence requiring revision. Completely procedure-related event with minor secondary contribution by the patient overweight condition. No further investigation is possible at this time. If product details and additional information becomes available to indicate further evaluation is warranted, this record will be reopened.
