The Zimmer Persona knee replacement system is a semiconstructed knee prosthesis that is used by many people suffering from conditions from arthritis and knee injuries. The system is comprised of modular components between the articular surfaces and tibial plates.

The Zimmer Persona knee replacement system is manufactured by Zimmer Inc., an Indiana-based company. The function of the device is to replace the articulating surfaces of the femoral bone, patellar bone and tibial bone.

However, reports have indicated that particular components of the system are associated with severe adverse health risks and complications. These complications, moreover, may possibly require revision surgery and other medical treatments.

The Zimmer Persona knee replacement system was manufactured to function as a replacement device for patients suffering from knee pain and disability. These patients may suffer from these conditions due to the following causes that include: failed previous attempts to fix the knee, post-traumatic loss of joint configuration, rheumatoid arthritis, osteoarthritis, and collagen disorders.

In recent years, the Zimmer Persona knee replacement system has been subject to a voluntary recall by the manufacturer, which was designated as a Class II recall by the FDA, particularly as a result of an increase in reports of loosening and radiolucent lines.

Patient complaints that led to the discovery of these complications include inflammation, knee tightness, knee instability, loss of mobility, and persistent pain.

The Zimmer Persona knee replacement device and Trabecular Metal Tibial Plate was voluntarily recalled by Zimmer Inc. in March 2015. The recall was marked by the U.S. Food and Durg Administration as a Class II recall.

According to the report of the recall, the recall affected all sizes and lots. It included the C-J Left and Right, and uncemented Trabecular Metal Tibial component.

Moreover, while Zimmer Inc. had announced the recall, they had also alerted the medical community, including doctors and hospitals of the plan to collect all quarantined medical devices and to, additionally, complete an Inventory Return Certification prior to having the recalled medical devices shipped back and returned to the manufacturer.

According to other reports of complaints pertaining to the Zimmer Persona knee replacement, the knee replacement device also had a tendency to loosen from where it had originally been implanted. MRI and X-ray reports illustrate gaps appearing between the implant and the bone, a problem known as “poor seating.”

Reports maintain that radiolucent lines form and appear on X-ray when an implant begins to loosen.

Although revision surgery may help decrease the issues resulting from a faulty Zimmer Persona knee replacement, it does come with its own set of complications. Complications and additional risks associated with knee implant revision surgery may include bone loss, infection, blood clots, fractures, and pain.
