The DePuy Attune Knee System from Johnson & Johnson Has Been Linked to Severe Problems
Like the Pinnacle metal on metal hip and the ASR hip system before it, the DePuy Synthes knee system has been the subject of significant adverse events reported to the United Stated Food and Drug Administration. These reports have prompted the FDA to issue a recall for an Attune Knee Tibial Articulation Surface instrument, after discovering that the Balseal, or the small wire spring coil used in the range of motion testing to aid in tibial location prior to drilling peg holes, can become damaged and detach. This is not the only problem with the Attune Knee system either as noted in the Journal of Knee Surgery in September of 2017. Individuals who received this knee replacement have reported premature device failure, some occurring within months of surgery. Most knee implants that are not dangerous or defective are expected to last for many years and in some cases decades. Thus, failure soon after the initial implantation is uncommon and serious. Many reports of early device failure related to a lack of bonding and loosening of the tibial base plate. Located at the base of the knee, the base plate bears a significant amount of weight from the body and its stability is vital. A loosening tibial baseplate may result in serious pain, bone loss, or muscle damage.These injuries can then impact other joints, such as the hips, and the rest of the body. The failure of a DePuy Attune Knee Replacement often requires painful and invasive revision surgery, and some of the damage caused by these defective knee implants may be irreversible.
The Attune Knee System, manufactured by Johnson & Johnson subsidiary DePuy Orthopaedics, is a major device on the market. It provides a great deal of revenue to Johnson & Johnson which is raking in huge profits as its knee business has grown 2.3% year to year and serves as a major part of the $6.3 billion the company made last year. Approved by the Food and Drug Administration (FDA) through the often criticized 510(k) process in 2010, the DePuy Attune Knee System was touted as being able to provide patients with increased stability and a better range of motion. DePuy marketed the device heavily by sending paid consultants and representatives into doctor's offices, and in certain circumstances, directly into the operating rooms during surgery. A large number of patients claim that the Attune knee replacement implants have not lived up to those expectations. In the years since its approval, the FDA has received numerous complaints from DePuy Attune patients who reported complications with their implant, including loosening of tibial components that necessitated painful and invasive revision or reconstructive surgeries. All of these complaints are available at the FDA website.
Thousands of the 600,000 knee implants performed each year are Johnson & Johnson Attune knee systems and patients have been implanted with the Attune Knee System. Symptoms associated with premature failures of the Attune Knee System include:
Instability and Loosening
Decreased Range of Motion
