Hip and Knee Prostheses

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 hurt 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; but, several prosthetic implants that have been sterilized in polyethylene have required additional surgical procedures.

Several companies use a technique known as gamma irradiation in air to sterilize the hip and knee prostheses. During the procedure, small pieces of the polyehtylene part of the device which was previously sterilized may break down and become stuck in the hip or knee joint of a patient. Osteolysis is a condition that is common in individuals with the extra pieces of material floating in their body. Osteolysis is when the immune system starts to attack healthy bones as well causing decay. Usually additional knee or hip prosthesis replacements will be required and more surgical procedures must occur.

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

. Howmedica Osteonics Corp.

. Howmedica, Inc.
