Section h10: the navio surgical system uk, part number rob00049, used for treatment was not returned for evaluation.A relationship between the reported event and the device could not be established.The clinical/medical investigation concluded that without the requested medical documentation, definitive clinical factors which could have contributed to the reported event could not be concluded.Of note, blood loss with subsequent transfusion(s) is a known potential occurrence during and/or post-surgical procedures and does not support a component malperformance.A complaint history review for similar reported/confirmed complaints concluded this was an isolated event.While all products meet required manufacturing specifications prior to release a serial number, lot number, part revision or software version is required to link the device to a dhr or nc investigation.As with any surgical procedure, there is risk involved.Potential complications accompanying surgery may occur, including: allergic reaction (anaphylactic and minor), infection, mild to serious physical injury, localized static shock, delay in the operation, surgical site nerve injury, vascular injuries of the lower extremity, soft tissue damage, major bone gouging at the surgical site, bone fracture, immature implant failure, unstable knee joint, limited or restricted knee range of motion, major blunt impact injury, unintended laceration/puncture wound, and osteonecrosis.The risk review could not be completed as no sufficient information was provided that relates the specific failure mode to the device.No reasonable contributing factors could be identified based on the received complaint information and investigation results.Based on the investigation, the need for a corrective action is not recommended or required at this time.Should any additional information be received the complaint will be reopened.The failure mode will continue to be closely monitored through complaint investigation and trended through post market surveillance activities.Internal complaint reference number: (b)(4).
