Hip surgery has been a slow-growing specialty in orthopedics and sports medicine. The development of imaging and minimally invasive arthroscopic surgery techniques has brought opportunities for this branch. Compared with other minimally invasive joint techniques, hip arthroscopy develops more slowly due to high equipment requirements, difficult operation and long learning curve. However, with continuous breakthroughs in disease diagnosis and surgical techniques, hip arthroscopy technology has stayed in a fast track for the past 20 years, and has become the most rapidly developed field in sports medicine. Especially in the past decade, China's hip arthroscopy society has developed rapidly in both surgery volumes and types. With an increasing population of hip doctors, the technical level and related research gap between China and the outside world narrowed. In some research fields, China even surpassed them. In general, both domestic and overseas studies show that the effect of hip arthroscopy is positive with significant improvement of symptoms in most patients. However, some patients complained poor recovery and residual hip pain, which indicates that hip diseases are still not totally understood, and the development of hip arthroscopy technology is still in an early stage. Therefore, accurate diagnosis and indication selection, detailed assessment of patients' exercise needs and psychological status, perfect preoperative planning, skilled surgical operation, and strict functional rehabilitation are the keys to success, which should be kept in mind by every hip arthroscopy doctor. They are also the main research direction for hip arthroscopy doctors. Continuous efforts on clinical and basic research should be made for the development of hip arthroscopy to establish a more optimized and comprehensive diagnosis and treatment system.
