A reflective commentary by Maurice Muller distilling five core principles from 30 years of total hip arthroplasty. It covers preoperative planning, component materials, operative technique, loosening detection, and standardized documentation. The piece frames polyethylene as the weak link in modern THA.
When you see progressive socket migration on serial films, act early rather than waiting for symptoms to catch up. Muller's central teaching is that the radiograph leads the patient: a hip can be failing structurally while the patient reports only vague discomfort. Delaying revision until pain is severe means operating into destroyed bone stock that then requires allograft and reinforcement cages.
His second lesson reframes the loosening debate. He argues polyethylene wear debris, not cement, drives most late acetabular osteolysis. This is the conceptual root of what later became the well-established understanding of particle-induced osteolysis.
For tracking failure, remember the hierarchy: migration and cavitation matter more than radiolucent lines. Measure cranial migration from the tear drop and watch for socket angle change signaling advanced loosening. This is a single-surgeon commentary, so treat the specific claims as expert opinion rather than controlled data.
