Defective Knee Replacement Device Complications
There have been several complaints of serious complications associated with knee replacement products. Many of the defective knee replacement devices are manufactured by Zimmer Biomet, and the DePuy ATTUNE Knee System has also recently been the subject of litigation.
Complications include component loosening, radiolucent lines, osteolysis, and component fracture. Many of these issues can cause the knee implant to fail. When this happens, replacement or revision surgery can be necessary to correct the problem.
Knee Replacement Component Loosening
Loosening of the installed device can cause the entire device to fail. This can be extremely dangerous because it can immobilize an individual as well as become extremely painful.
Component loosening has been a reported issue in almost every Zimmer knee recall issued by the FDA. Component loosening has been a documented issue with the Persona Trabecular Metal Tibial Plate, the MIS Tibial Components, and the NexGen LPS-Flex GSF Femoral Component.
It is also the major problem with the ATTUNE Knee System. The unusually high rate of early failure in ATTUNE Knee System is a result of tibial components loosening, causing pain and decreased range of motion as early as two years after surgery.
Knee Replacement Radiolucent Lines
Radiolucent lines are small holes or gaps that lie between the device and the bone, or between device components. Usually, radiolucent lines occur because the device was not installed and secured properly. Issues arise when these gaps fill with joint fluid or tissue. Additionally, debris from implant wear can become lodged in the radiolucent lines. If untreated, osteolysis, or bone damage, can occur. This can also lead to component loosening and failure.
Knee Replacement Osteolysis
Osteolysis is the process of reverse ossification, or bone damage. The placement of foreign objects inside the body can cause the body to attack its own bone cells. In the case of knee replacement, radiolucent lines can become filled with fluid or debris, which can lead to serious bone damage.
Knee Replacement Device Fracture
Device fracture is a serious complication associated with some artificial knee devices. The January 2012 recall of the Natural-Knee II Durasul All-Poly Patella made by Zimmer occured because several reports had identified that the device was prone to fractures. This caused device failure and additional patellar problems.
