The biomechanics study of the hip is aims to understand and explore the dynamic principles of weight transfer through the hip joint. This basic science knowledge can be applied in a variety of areas, including degenerative joint diseases and hip replacement arthroplasty. In particular, understanding of the biomechanics of the hip has led to the development of materials, design and fixation of implants, and it can be applied in various areas, such as the selection of surgical methods and the location of the implant. Moreover, it is essential to have good knowledge of the biomechanics of the hip to achieve better clinical results for patients. Therefore, this paper introduces the basic knowledge and biomechanical characteristics of a normal hip and hip replacement arthroplasty, which are needed to approach the biomechanics of the hip.
