Prosthetic Implants

By: Alan Haburchak

A prosthesis is an artificial replacement of or substitute for a part of the body. Prostheses may be removable or may be permanently implanted. A prosthesis is used for functional or cosmetic reasons or in many cases, a prostheses is used for both. Hip and knee prostheses are permanently implanted to replace a hip or knee that was not functioning properly or has had years of wear and tear from an individual.

Hip and knee replacements are among the most common surgical procedures in all of orthopedic surgery. The procedure involves replacing damaged or deteriorated joints with artificial replacements, which include parts made of high molecular weight polyethylene, similar to pliable plastic. Most patients who undergo a hip or knee replacement gain improved agility, flexibility, and reduced pain; however, due to the practice of sterilizing polyethylene, some replacements have failed prematurely, resulting in injury, and causing the need for further surgery to replace the failed parts.

Several companies use a technique known as gamma irradiation in air to sterilize the hip and knee prostheses. This sterilization process has caused the polyethylene part of the devices, once implanted in the body, to break into small pieces which then can lodge into the patient's hip or knee joint. In the body's fight to rid itself of those pieces, the immune system can also attack the patient's healthy bone, causing it to decay, a condition known as osteolysis. The patient inevitably needs another potentially risky surgery to replace the hip or knee prosthesis long before expected.

Several of the following manufacturers are under investigation for faulty hip and knee implants that were manufactured in the early 1990s:

. Depuy

. Howmedica Osteonics Corp.

. Howmedica, Inc.

. Osteonics Corp.

. Zimmer

. Biomet

A detailed evaluation of an individual's medical records is one way to determine compensatory and physical damages incured for patients of knee or hip replacement with prostheses.

However, for those who have been involved in knee or hip replacement, the possibility to develop a hip or knee replacement lawsuit is available. To learn about hip or knee prostheses litigation, contact an experienced law firm. The victim, or plaintiff, may have the possibility to develop a medical lawsuit to seek compensatory damages for pain and suffering as well as overall medical bills.
