What should patients do?
Contact your surgeon or health care provider if you have a SMR MB L1 Liner implanted, and you experience any of the symptoms mentioned in the ‘What are the risks’ section above in your implanted device.
What should health professionals do?
Monitor patients who have the SMR MB L1 Liner implanted in the anatomic configuration for potential device wear or bone loss. Consider performing X-rays to further evaluate a patient and their implanted device if you suspect a problem with the SMR MB L1 Liner.
In patients who may have worsening symptoms, based on clinical exam and on a case-by-case basis, discuss the benefits and risks of all relevant treatment options with your patients.
