Manufacturer Narrative

It was reported that, during a total knee arthroplasty, using the rt plus monoblock loan instruments, the surgeon could not assemble the tibial rt plus monoblock loan cutting jig in the reamer, instead had to use the gen ii tibial cutting jig.The procedure was completed with a delay less than or equal to 30min, using smith-nephew back-up devices.No patient injury or other complications were reported.The device, intended for use in treatment, was not returned for investigation.The production documentation review could not be performed since the lot number was not provided.A complaint history review was performed.Based on performed medical investigation, smith+nephew is unable to rule out a procedural variance as a contributing factor to the reported event.According to the report, the surgeon was able to be complete the procedure with a delay less than 30min, using s+n compatible back-up devices.The reported procedural modification did not result in patient injury, so no further medical assessment is warranted at this time.Normal wear and tear through repeated use is known to contribute to the reported event.According to document "processing (cleaning, disinfection and sterilization) of instruments from smith & nephew orthopaedics ag" (lit.N°03389-en 1363 v3 11/19), all devices must be inspected and controlled for proper functioning after cleaning/disinfection.Furthermore, instruments should only be used in their original condition (lit.No.Lit.No.12.24, ed.07/10).The failure mode and the severity of the reported issue are covered in the corresponding risk management file of s+n.However, the reported connection problem cannot be investigated any further due to lack of information.Hence, a relationship between the reported event and the device cannot be confirmed and the root cause could not be determined conclusively.Based on the available information it is not possible to investigate whether the reported device met manufacturing specifications upon release for distribution.The need for corrective or further actions is not indicated at the time.Should more information become available, the investigation will be reopened.Smith+nephew will continue to monitor for similar issues.
