Abstract

Highlights: It is estimated that the femoral and acetabular cups will run-in at 1–2 million cycles in a hip joint simulator or 1–2 years in vivo. Ceramic-on-ceramic and ceramic-on-metal bearings combination have a lower running-in wear rate compared to other pairs. The diametral clearances between 50 and 150 μm exhibit minor wear. Abstract: Total hip arthroplasty is a short-term solution for replacing a damaged hip joint with synthetic biomaterials. Total hip arthroplasty comes in two flavors: single and dual mobility. Mechanical and biological factors may degrade the quality of biomaterials over time. This may lead to implant failure and second surgical treatment. Wear is the crucial element leading to damaged bone and debris release throughout the body over time. Running-in is the initial wear phase between two surfaces before the steady-state phase. The stage of running-in is critical for understanding hip joint wear. Running-in and wear behavior have been extensively studied in single-mobility total hip arthroplasty, but aseptic loosening is the leading reason for restoration in arthroplasty registries. This paper seeks to summarize running-in behavior on single mobility hip implants, emphasizing its key aspects and recent developments.
