Hip replacement is a surgical procedure in which parts of a hip joint are removed and replaced with a prosthesis, most commonly made of titanium-based alloys. Although considerable advances have been made in this field, the fracture is still one of the main problems associated with hip implant failure. This paper deals with the analysis of the premature failure of hip joint replacement. A 61-year-old patient underwent a left hip replacement in 2008, and revision surgery was required after 10 years. Many possible causes of failure include incorrectly chosen material microstructure, heat treatment, fatigue cyclic loading, or hydrogen embrittlement. This paper focuses on saturating the endoprosthesis with hydrogen. By examining the amount of saturated hydrogen in the Ti6Al4V alloy, it is possible to predict the fatigue life of the endoprosthesis. Comparison the hydrogen content in a used implant and sample saturated by cathode method, we estimate the amount of hydrogen that will be diffused in regular use. The experiment aims to find out and eliminate risk factors and reduce the number of revision surgeries for prematurely failed hip joint replacement. In practice, this means ensuring a dignified life for patients after surgery.
