The location of the hip joint is deep in, the gap is narrow, and the hip joint disease is complex, with both sports injury and joint degeneration, which seriously affects patients’ daily work life. Conventional incision surgery has large incisions and requires intraoperative surgical dislocation of the hip joint before the surgery can be performed, which results in heavy damage, easy infection and slow recovery. With technological advances, we are now able to apply arthroscopy for minimally invasive diagnosis and treatment of hip joint diseases, i.e. hip arthroscopy technology. If the indications are selected accurately, hip arthroscopy has huge advantages over traditional open surgery. The advantages of hip arthroscopy: 1. It can detect lesions that could not be detected in the past, such as round ligament injury and cartilage injury; 2. For specific lesions, such as femoroacetabular impingement (FAI) and synovial lesions, hip arthroscopy is significantly less invasive compared with open surgery, and can minimally invasively remove the impingement factor, remove the diseased synovium, and remove the free body; 3. Hip arthroscopy can remove the impingement factor, remove the diseased synovium, and remove the free body; 3. For glenoid labral and cartilage injuries that cause hip pain, hip arthroscopy can clearly diagnose and minimally invasive forming or repair treatment; 4. lateral approach, anterolateral approach and posterolateral approach, hip arthroscopy can be completed through three 0.5 cm incisions, and most treated patients can quickly relieve symptoms and resume daily work life early, or even return to the sports field. For patients who have hip pain, that is, pain at the root of the thigh, they should seek timely consultation with a specialist for early management and should not delay their condition to avoid late replacement surgery.
