Action On 08/27/2021, the Recalling Firm communicated via email a letter to customers/US surgeons informing them that they are initiating a product recall limited to its 25 mm segment from its knee system due to an out of specification condition that has the potential to pose a risk to patients. Customers are instructed to return unused products. For questions, contact the Director of Customer Service at 949-328-3366 or the Vice President of Marketing at 949-501-8575.

In addition, this updated notification was also informing their customers, if they have any patients with the affected product implanted, the Recalling Firm's investigation did not reveal any reason to suggest that there is any imminent danger to the patient since the noted failure was primarily due to a fall from height. It is up to the medical discretion of the treating physicians regarding whether or not to notify the patient. It is also up to the medical discretion of the treating physician whether or not to consider a revision surgery to replace the affected segment.
