Abstract:Since the 21st century, sports medicine makes progress rapidly. However, hip arthroscopy development is relatively late due to the complexity, deep site of the joint structure that brings operation difficulty, compared to other major joint. As deepening researches on femoroacetabular impingement (FAI) , more and more hip arthroscopy techniques emerges, which leads incredible increase of the num- ber of hip arthroscopic procedures with technique advances by leaps and bounds. In recent years, domestic experts in hip arthroscopy in- herit the solid foundation laid by the older generation of experts, actively absorb international hip arthroscopy advanced concepts and tech- nology, adhere to self-innovation and development, hip arthroscopy has been well popularized, and gradually keep up with the pace of in- ternational development. During this period, a series of new ideas and techniques were generated, which laid a good foundation for the in- novation, development and popularization of hip arthroscopy in China, and also played a positive role in promoting the global development in this field.
