Result of investigation: the reason for the revision cannot be confirmed from the information provided, but may be the result of prosthesis wear of the tibial insert as reported, femoral loosening, or due to inclusion of the polyethylene in the packaging recall.However, the reported femoral loosening could not be confirmed and potential contributions of patient-related considerations to the event could not be assessed since relevant clinical information was not provided.Based on the provided images, there does not appear to be wear of the patellar component.
