Event Description

Revision of a stryker triathlon total stabilized knee. This is the patients 3rd revision. The patient presented to the doctor with tibial pain. X-ray showed there had been potential loosening of the tibial component and deformity. During surgery the doctor identified tibial component with stem had become loose and removed it. The femoral component was also removed because it was not well fixed. The femoral component disengaged from the tibial component (corrosion at the taper of the stem and tibial component). Removed the femur (cemented in with 150mm presfit triathlon stem). Distal femoral replacement connected to stryker monogram rotating hinge. Surgery completed to doctor's satisfaction.

 
Manufacturer Narrative

An event regarding loosening involving a triathlon femoral distal augment 10mm ¿ size 3 right was reported. The event was not confirmed. Method & results: device evaluation and results: burnishing, scratching and third body indentations were observed on the articulating surface of the insert. These are common damage modes of uhmwpe. The post of the insert fractured in fatigue. The debris and discoloration observed on the insert, femoral component and baseplate were consistent with biological material. Debris from the stabilizing post was determined to be inconclusive based on the obtained eds spectrum. No material or manufacturing defects were observed on the surfaces examined. Medical records received and evaluation: based upon the minimal information available for review, no determination can be made regarding the cause of the three revisions of the right total knee arthroplasty. Medical review addendum: ¿based upon review of this additional documentation, no determination can be made regarding the cause of the three revision surgeries of the right total knee arthroplasty in this case. ¿ conclusions: the event could not be confirmed nor the root cause of the reported event determined due to the minimal medical documentation received for the clinician to review and evaluate. The mar report concluded that, ¿the debris and discoloration observed on the insert, femoral component and baseplate were consistent with biological material. ¿ ¿no material or manufacturing defects were observed on the surfaces examined. ¿ based on a visual inspection the augments are affixed to the femoral component and there is a large amount of cement around the devices. The side of the augment that are viewable has abrasions and possible corrosion. No determination can be made if the augments may have contributed to the loosening of the devices. No further investigation for this event is possible at this time as insufficient information was received by stryker orthopaedics. If additional information becomes available, this investigation will be reopened.
