Plaintiff sued the manufacturer of his hip replacement for product liability failure to warn and defective manufacture.  This decision affirms summary judgment for the defendant.  The failure to warn claim failed because plaintiff’s doctor who chose and implanted the hip replacement testified that he kept closely abreast of developments in hip replacement surgery and was aware from reading scientific journals of the risk of release of metal ions–the risk that plaintiff claimed defendant had failed to warn about.  Since the doctor already knew of that risk, the failure to warn could not have caused plaintiff’s injury.  The manufacturing defect claim failed because the hip parts were inspected at the factory before shipping and by the doctor before the operation, and were found free of defects both times.  That the FDA had criticized defendant for lack of validation of suppliers processes meant nothing.  Plaintiff had to show a defective product, not a defective process of inspection.
