Negligent Hip Replacement Surgery Allegedly Causes Implant To Fail

    Orthopedic Surgery Expert

    This case involves an 80-year-old male patient who underwent a hip replacement revision for his left hip. He required a revision due to infection in his first implant. Because of the infection, the patient required a second implant as well as a femur implant. The patient was transferred to a rehabilitation facility for physical therapy. Approximately 3 weeks into physical therapy, the patient was being lifted in a Hoyer lift when he felt a sudden severe pain. He was taken to the hospital where it was discovered that his hip replacement had dislocated and he required emergency surgery. The patient suffered numerous complications as a result of the third surgery. An expert orthopedic surgeon was sought to speak to causation and damages.

    I am an orthopedic surgeon with 20+ years of experience in the field of orthopedic surgery. I specialize in total hip replacements and knee arthroplasty, and I perform approximately 300 hip replacements per year. Some indications that the implant for a patient with a hip replacement was not properly placed at the initial surgery, leading the hip to be more prone to dislocation, include the following: the femoral component excessively anteverted or retroverted, the femoral stem not axial aligned down the femur or not in the canal.
