Event or Problem Description
As reported, during the initial implant for this (b)(6) female patient, the polyethylene tibial insert size1, 9mm two (2) pieces were cracked when the surgeon was inserting the tibial insert driver (before impaction).The crack was found damaged in the area in central mushroom hole, peripheral rim and backside of articular surface.The operation time delayed about one hour.The devices will be returned.
Additional Manufacturer Narrative
(h3) the evaluation noted that revision reported was likely the result of seating difficulties from not properly aligning the posterior undercuts of the tibial inserts with the mating geometry of the tibial tray, which prohibited the components from fully seating and led to deformation of the polyethylene.The most probable root cause associated with the reported event of " crack" is associated with assembling or seating a polyethylene component during implantation.This is one of two products involved with the reported event and the associated manufacturer report numbers are 1038671-2021-00198 and 1038671-2021-00199.
