Orthopedic surgery expert witness advises on woman’s claim that a defective knee replacement component caused her injury. The plaintiff was diagnosed with osteoarthritis and patellofemoral malalignment. She underwent a total knee replacement using a system designed by the defendant. After a few months, the plaintiff was in pain, and another surgery was performed. A piece of the knee prosthesis — a polyethylene tibial insert — was replaced.
After the procedures she developed an infected right total knee prosthesis and underwent a prolonged and debilitating course of multiple extensive surgeries, hospital admissions, rehabilitation and prolonged courses of antibiotics and pain medications.
