Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information.The following sections were updated: b2, b4, b5, d1, d2a, e1, g1, g3, g6, h1, h2, h3, h6, h11.Disease progression of osteoarthritis can continue in native bone structures as a patient continues to age.Other patient comorbidities, lifestyle, physical activities and some medications can increase the patient¿s risk for progressive osteoarthritis.Additionally, females have an inherent risk.Partial knee replacement is done to decrease pain, and increase flexibility, mobility and overall improve quality of life, as this is one of the least invasive approaches.Patients with disease progression of osteoarthritis in the affected joint develop knee pain and decrease in joint flexibility.As osteoarthritis progresses a loss of cartilage in the previously unaffected area of the knee has deteriorated to a point in which the patient and doctor may elect to take an approach to convert to a full knee replacement to alleviate symptoms.No product was returned or pictures provided; visual and dimensional evaluations could not be performed.The root cause of the reported event was determined to be unrelated to the device.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
