The Facts: Failure of the ATTUNE® Total Knee Replacement System
These researchers evaluated clinical and radiographic findings and findings occurring during revision surgery on patients who had the ATTUNE® knee replacement. They reviewed the findings from the MAUDE database and three hospital databases.
Within two years after receiving the ATTUNE® total knee replacement system, patients presented with symptoms including:
- Pain with bearing weight
- Pain in the front of the knee localized in the tibial area
- Effusion (increased fluid within a joint cavity)
- Decreased range of motion
Radiographic and intraoperative findings revealed gross loosening of the tibial (inner lower leg bone) component at the implant cement interface. Researchers found 21 reports of this tibial loosening in a two-month period in the MAUDE database.
