Acetabular fractures and their associated injuries to acetabular, femoral cartilage and femoral head blood supply will frequently lead to post-traumatic arthritis, avascular necrosis, or both. For displaced fractures, surgical intervention with open reduction and internal fixation (ORIF) has been demonstrated to optimize joint function and ultimately reduce the risk of developing posttraumatic arthritis but even after anatomic reduction, defined as ≤ 1 mm of displacement, posttraumatic arthritis develops in 12% to 67%.There are two main reconstructive arthroplasty options: acute (early) and delayed (late) total hip arthroplasty. Acute or early THA refers to performing THA as a definitive treatment during the acute fracture setting where ORIF would predictably lead to a poor clinical outcome
