title: [Painful hip arthroplasty: a diagnostic algorithm].
abstract: The number of implantations of hip prostheses in Germany is now approximately 190,000 per year. By improving the implants and the development of modern surgical techniques and instruments the revision rate has been significantly reduced. The survival rate of the implants could be further increased in recent years, however, up to 22% of patients complain about persistent pain after hip arthroplasty. The diagnosis of existing pain after total joint replacement of the hip joint to achieve a causal therapy needs a systematic approach because of the heterogeneity of the symptoms and diseases. The etiology of the pain can be joint-associated and also hip joint independent. Often the causes of pain are multifactorial so that a standardized assessment should be conducted using an algorithm. The clarification of pain begins with the history, inspection and palpation followed by a clinical examination. It is then useful to perform radiological imaging followed by invasive procedures if necessary. The exploratory revision is nowadays considered to be obsolete in the literature.
