Johnson & Johnson/Depuy Recall
Defects have been reported in the Johnson and Johnson and Depuy Ultra High Molecular Weight Polyethylene knee and hip prostheses, leading to a recall of the medical device manufacturer’s products. The material used by Johnson & Johnson and Depuy to manufacture the hip and knee prostheses is polyurethane, a type of plastic and rubber composite that has been known to degrade at a fast rate when exposed to radioactive waves.
Apparently, Johnson & Johnson and Depuy, in an effort to sterilize the hip and knee replacement prostheses, exposed them to gamma radiation, which ultimately caused the majority of the prostheses to crack, break, and develop an overall brittle material quality.
Smith & Nephew Implant Recalls
In early 2008, Smith & Nephew announced a recall of their Oxinium Genesis II and Oxinium Profix II knee replacement systems. The Smith & Nephew knee prostheses, in which the femoral component was “macrotextured”, has had a high degree of failure due to loosening of the femoral component. Patients who received an implantation of the defective Smith & Nephew knee replacement prosthesis have required revision surgery.
Stryker Corporation Subsidiary Howmedica Implant Recalls
After an investigation led by the U.S. Food and Drug Administration in 2007, the Stryker Corporation issued a recall notice for two of its hip prostheses, the Trident Acetabular PSL and the Hemispherical Acetabular Cup. Individuals who have undergone surgery to receive one of the Trident model ceramic hip replacement prostheses began noticing, above all, an odd squeaky noise coming from the prosthesis during joint movement. Patients have also suffered from severe pain, bone fractures, and fragmentation and cracking of the ceramic prosthesis.
Biomet Implant Recalls
In 2001, Biomet was one of eight U.S. medical device manufacturers who collectively and voluntarily recalled hip prosthesis models that included zirconia ceramic femoral heads made by a French company called St. Gobain Desmarquest. The recall was prompted by reports of the zirconia ceramic femoral heads cracking, fracturing, and breaking only a year after being used as a component in a hip prosthesis.
The 2007 Biomet recall involved improper laser etching execution for size in a specific model of the medical device manufacturer’s tibial bearings. In 2008, Biomet released another recall for the Modular Microplasty Cup Inserter, a major component of Biomet’s hip prostheses.
Sulzer Medica Recalls (Now Centerpulse Orthopedics)
In 2001, Sulzer Orthopedics, which is a branch of Sulzer Medica, a pharmaceutical and medical device company based in Switzerland, announced a recall of its knee prostheses due to the discovery of a critical defect. The recalled knee prosthesis system is known as the porous-coated stemmed tibia base plate. It came to light that during the manufacturing process, despite efforts to meet cleanliness standards for the production of medical devices, Sulzer Orthopedics was distributing knee prostheses that were covered in a mineral oil residue.
Evidently, the Sulzer knee prosthesis, when the oil residue was present, was completely unable to meld with adjacent bones, resulting in a poor fit, knee and joint pain, and further damage and injury.
Wright Medical Conserve Hip Replacement Recalls
Wright Medical announced a recall in 2004 of their hip replacement system within the Conserve line of hip prostheses. The Conserve and Conserve Plus hip prosthesis systems involved a metal on metal design, which often resulted in metal fragments coming loose and entering the patient’s body. Wright Medical’s Conserve hip replacement system included a manufacturing defect in the metal acetabular hip cups involving the inclusion of a metal ridge in the interior metal acetabular cup.
With implantation of the Wright Medical hip replacement system, it became clear that metal fragments were being rubbed off of the metal ridge, and entering the patient’s body, causing both severe pain and serious health problems as well as necessitating revision surgery to correct the defective Wright Medical hip replacement prosthesis.
Encore Orthopedics Recalls
A labeling error sparked the recall process in 2004 by Encore Orthopedics, a medical device manufacturer. Due to the wrong labels being applied on Encore’s 3D Knee System medical devices and their Foundation Knee System medical devices, Encore initiated a voluntary recall of all of the products within these lines of knee replacement prostheses.
Furthermore, in 2008, Encore Orthopedics announced another recall, this time of the Foundation Knee System Tibial Fixed Impactor component. According to Encore Orthopedics representatives and knee replacement surgeons, an integral component, the Nitronic 60 screw in the knee replacement prosthesis system, was starting to show signs of cracking, and in some cases was breaking apart entirely, during surgical operations.
Zimmer Durom Metasul Hip Cup Replacement Recall
The defective status of the Zimmer Durom Metasul Hip Cup came to light in early 2008, which is when surgeons began taking notice of the large quantity of revision surgeries necessary only a couple of years after individuals had received an implantation of the Zimmer Durom Metasul Hip Cup. As of 2008, approximately 13,000 individuals had undergone surgery to receive the Zimmer Durom Metasul Hip Cup.
As most hip prostheses are designed for older patients who will not significantly wear down their hip replacements through years of activity, the design objective behind the Zimmer Durom Hip Cup was to stand in contrast to the traditional hip replacement prostheses targeted for the elderly. The Zimmer Durom Hip Cup was designed with durability in mind, and geared towards younger, more active individuals.
Unfortunately, the Zimmer Durom Hip Cup had a huge design flaw, resulting in the metal portions of the hip cup being unable to fuse with adjacent bones.
It is understood that the knee and hip replacement prostheses outlined above are defective, have the potential to malfunction, cause serious harm, require revision surgery, break, fragment, and become loose. Patients with these defective and recalled knee and hip replacement prostheses often need further surgical operations, known as revision surgery, that result in another exhausting and painful recovery period.
Furthermore, the need for revision surgery accrues medical and financial expenses and compromises the well being of patients by exposing them to complications from surgical operations.
