Event Description

Hcp is reporting to nca/bfarm: "(b)(6) 2023: implantation of knee-tep: bicondylar surface replacement prosthesis: cemented left (5-822.G1) implantation of an endoprosthesis at the knee joint: patellar replacement: patellar back surface, cemented left (5-822.81).After knee-tep implantation initially symptom-free interval of 4 months.Cracking noise with forced flexion during physiotherapy.In the course progressing feeling of instability in the area of the left knee and intermittent pain.Radiologically no abnormality is evident, optimal knee-tep in flexion and extension as well as optimal integration of the implanted implants.(b)(6) 2023: during the revision surgery a dislocation of the inlay is detected.The inlay is lifted out of the guide raised in ventral direction.This results in a corresponding ventral dislocation of the inlay.Change of inlay takes place.".

Manufacturer Narrative

Product complaint #: (b)(4).Investigation summary: hcp is reporting to nca/bfarm: (b)(6) 2023: implantation of knee-tep: bicondylar surface replacement prosthesis: cemented left (5-822.G1).Implantation of an endoprosthesis at the knee joint: patellar replacement: patellar back surface, cemented left (5-822.81).After knee-tep implantation initially symptom-free interval of 4 months.Cracking noise with forced flexion during physiotherapy.In the course progressing feeling of instability in the area of the left knee and intermittent pain.Radiologically no abnormality is evident, optimal knee-tep in flexion and extension as well as optimal integration of the implanted implants.(b)(6) 2023: during the revision surgery a dislocation of the inlay is detected.The inlay is lifted out of the guide raised in ventral direction.This results in a corresponding ventral dislocation of the inlay.Change of inlay takes place.The product was returned to depuy synthes for evaluation.The depuy synthes team conducted a visual inspection of the returned device.Visual analysis of the components revealed deformation and breakage on the corners of both posterior grooves intended to slide into the locking feature of the mating tibial tray.This deformation and breakage suggest that the insert was not properly aligned with the tibial tray during insertion attempts.Consequently, it is reasonable to suspect that the insert would disassociate from the tray if not adequately seated.Additionally, witness marks including scratches, pitting, and significant wear were observed on the flat surface of the fixed back side of the insert.Such marks are consistent with the improper seating of the insert from the start.Although the mating tibial tray was not returned, the visual damage observed on the insert provides confirmation of the disassociation event.Moreover, the reported "cracking noise" aligns with the breakage found on the corners of the posterior grooves as the noise likely originated from the corners pushing down on the edges of the mating feature while the knee was flexed, causing the weaker poly material to fail over time.The attune knee system surgical technique (dsus/jrc/0316/1437 rev.K) advises on pages 79-80, ¿for fixed bearing tibial components, angle the tibial insert posteriorly and slide the posterior tabs into the posterior undercuts of the tibial base.The fixed bearing tibial insert is impacted into place on the tibial base, using the fixed bearing insert impactor.Position an impactor at approximately 60 degrees on the insert so that the notch rests on the anterior edge of the center of the insert.Use a mallet to strike the fixed bearing insert impactor.¿ following these steps will successfully locking the insert into the base as intended.The observed damaged condition suggests the posterior grooves on the underside of the tibial insert were not properly aligned with the undercut locking features of the tibial base.This would contribute to disassociation event between the insert and tibial tray.The overall complaint was confirmed as the observed condition of the attune ps fb insert would contribute to the complained device issue.Based on the investigation findings, the potential cause is traced to unintended user error, and no corrective and/or preventative action is proposed.There is no indication that a design or manufacturing issue has caused the reported complaint condition.As part of depuy synthes quality process, all devices are manufactured, inspected, and released to approved specifications.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post-market safety surveillance activities.Device history lot: 1) quantity manufactured: (b)(4).2) date of manufacture: 29-10-2021.3) any anomalies or deviations identified in dhr: none.4) expiry date: 30-09-2026 5) ifu reference: (b)(4).A manufacturing record evaluation was performed for the finished device product description: attune ps fb insrt sz 8 8mm product code: 151640808 lot number: jn3131 and no non-conformances or manufacturing irregularities were identified.- sp.
