    ICJR CASES: Managing Revision Total Hip Arthroplasty Patients

    A patient who underwent staged bilateral total hip arthroplasty (THA) 10 years earlier with metal-on-metal implants presents for a second opinion. She’s had increasing pain in both hips, left worse than right, for about a year. Her formerly low cobalt and chromium levels are now markedly increased, and imaging shows massive soft tissue collection around both hips.

    She clearly needs a revision THA. What would be your plan for this procedure? Now, factor in that her body mass index (BMI) is 50 and that she has a history of bilateral deep vein thrombosis (DVT). How does that change your thought process?

    This is 1 of 4 cases presented by Mark W. Pagnano, MD, from Mayo Clinic, Rochester, Minnesota, during a panel discussion on revision THA at the ICJR East ISK Hip & Knee Course. Panel members included Michael P. Bolognesi, MD; Richard Iorio, MD; and Ran Schwarzkopf, MD, MSc, and during the session, they discussed how they would manage the following cases:

    Case 1

    • Male patient who underwent staged bilateral THA in 1991, with revisions for polyethylene wear, acetabular loosening, and osteolysis in 1997 (right hip) and 1999 (left hip)
    • Patient fell in 2015; no fracture
    • Patient presents in 2017 with progressively increasing hip pain that interferes with activities of daily living

    Case 2

    • 74-year-old female patient who underwent staged bilateral THA in 2007 with metal-on-metal implants
    • Asymptomatic, but has undergone intermittent chromium and cobalt level testing since 2010
    • Developed bilateral deep vein thrombosis requiring stenting of her left external iliac and femoral veins
    • Patient presents with a 1-year history of bilateral hip pain, left greater than right

    Case 3

    • 54-year-old male patient with trisomy 21 and dementia
    • Complained of right hip pain after an unwitnessed fall
    • Previously able to ambulate, but refused to walk after the fall
    • Diagnosed with displaced femoral neck fracture and undergoes primary THA

    Case 4

    • 69-year-old male patient who underwent right THA in 1999 and left THA in 2001
    • Patient presents with worsening groin pain and no history of trauma
    • Imaging shows massive lysis around both sockets
