Event Description
|
Primary procedure, left stryker partial knee.It was reported that upon opening the box for a size 4 left medial tibial baseplate, the device and implant stickers inside the box were for a 3x8 left medial tibial insert.The surgeon elected to wait for the correct implant to be retrieved, but after 1 hour 15 minutes (both with and without use of tourniquet) decided to cement in a size 3 tibial baseplate.The original 3x8 insert was not used, a 4x8 insert which had been opened (as per original surgical plan) was wasted, and a different 3x8 insert was used to complete the surgery successfully.The outer box, device stickers, and device in its sterile blisters have been retained.

An event regarding a product swap involving a triathlon baseplate was reported.The event was not confirmed.Method & results: device evaluation and results: visual inspection was performed as part of the material evaluation and indicated the following comments: the carton received is labeled with "triathlon pkr tibial baseplate" on the side panel.Catalog number listed is "5620-b-401".Lot number listed is "jszna".Clinician review: no medical records were received for review with a clinical consultant.Device history review: all devices were manufactured and accepted into final stock with no relevant reported discrepancies.Complaint history review: there have been no other similar events for the reported lot.Conclusion the product manufacturing cell representative reviewed the event and stated: no indication of quarantine or nonconformances were found to be documented within either dhr for each of the products tied to this complaint manufacturing dates for both devices are over a year apart.This is evidence that this potential product swap was not created from a manufacturing error.Therefore, this complaint does not require escalation to a non conformance.No further investigation for this event is possible at this time as insufficient information was received by stryker orthopaedics.If additional information become available to indicate further evaluation is warranted, this record will be reopened.
