Prior to confirmation of the settlement, rumors were swirling about the amount the company would have to pay.

Early reports said the company was willing to pay more than $4 billion to settle thousands of lawsuits over its faulty ASR hip implants, according to Bloomberg news, which cited three sources familiar with the deal.

The settlement resolved more than 7,500 lawsuits filed against JNJ’s DePuy Orthopaedics unit in state and federal courts by patients who have had the defective replacement joints removed.

The company spent months preparing for the first federal trial involving its recalled ASR implants but the case was postponed three times due to difficulties scheduling expert witnesses and depositions.

Dr. Russ Nevins will perform a revision total knee replacement using the Sigma® TC3 RP and M.B.T. Revision Tray system from DePuy Orthopaedics, Inc. The broadcast will be moderated by Dr. William Barrett (Renton, WA). This broadcast will take place from Spring Valley Hospital Medical Center in Las Vegas, NV.

At 4PM Pacific (7PM EDT), Dr. Nevins will perform the revision total knee replacement surgery featuring the Sigma TC3 RP, a rotating platform knee implant design. This system helps diffuse loosening forces from the increased mechanical constraint typical in revision implant systems and offers surgeons enhanced fixation options through the use of metaphyseal sleeves on the femoral and tibial side.

About Revision Knee Replacement
Currently there are over 50,000 revision total knee surgeries performed every year in the United States.1 Although there are a variety of reasons that a primary knee replacement ultimately fails, the most common causes are for infection, instability, and loosening of the tibial/femoral implants.2 During a revision knee surgery, it is important to consider an implant system that is able to address these complex surgical issues. The DePuy Sigma TC3 Revision incorporates rotating platform technology that features an insert that is free to rotate about a central post. This motion decouples the torsional forces between the tibial insert and the tibial tray. In published studies, a mobile bearing construct has been shown to decrease loosening forces by 68-73%.3
As with any medical treatment, individual results may vary. Only an orthopaedic surgeon can determine whether an orthopaedic implant is an appropriate course of treatment. There are potential risks, and recovery takes time. The performance of the new joint depends on weight, activity level, age and other factors.

Evidence - ATTUNE® Knee System - Clinical Evidence

The new knee is designed to provide better range of motion and address the “unstable” or “wobbly” feeling some patients report during everyday activities, such as bending, going down stairs, or even something as routine as getting out of a car, officials said.

To achieve an improved feeling of stability for patients, the team at DePuy had to throw out convention and come up with a new implant that might at first glance appear to be the same as other knee replacement technology, but upon closer inspection differs from previous generations of devices in shape, form and function.
