Today’s decision is that simple. Actually, it’s that simple and it’s that surprising that plaintiffs tried to side-step this golden rule of complex drug/device products liability litigation. You must have expert testimony.
In Chatman v. Zimmer, Inc., 2016 U.S. Dist. LEXIS 78657 (S.D. Miss. Jun. 16, 2016), plaintiff alleged she suffered injury as a result of implantation and subsequent failure of her knee implant. The device was implanted in 2006 and in 2013 plaintiff started experiencing pain that led to revision surgery. Id. at *2. Rather than producing an expert to opine regarding product defect or medical causation, plaintiff informed the court she would be relying on “her own accounting of the events, records from her treating physicians, and a recall notice.” Id. at *3. We don’t need to know anything else. There is no way any of those three sources could satisfy the requirement that plaintiff produce expert testimony as to the alleged defect.
The court first threw out the recall notice because it pertained to a different knee replacement device than that implanted in plaintiff. Plaintiff apparently cited to cases involving commercial products to argue the admissibility of substantially similar circumstances. But this wasn’t similar circumstances, it was an entirely different product. Therefore, the recall is irrelevant. Id. at *5.
So plaintiff is down to “her own accounting” and her “medical records.” Plaintiff’s “own accounting” cannot establish product defect or medical causation. Plaintiff did not appear to be either a biomedical engineer or an orthopedic surgeon. The fact that her knee implant eventually failed after seven years and that she experienced pain are facts – but they have no connection to liability without expert testimony on defect and cause.
