Hip impingement syndrome, also known as femoroacetabular impingement syndrome, is a disorder in which abnormal contact or collision occurs between the proximal femur and the acetabular rim at the end of hip motion due to abnormal anatomical patterns of the femoral head and acetabulum, which in turn causes cartilage damage to the glenoid labrum and acetabular rim, resulting in hip pain. It is one of the most common causes of hip pain in young people. Patients mostly feel pain at the root of the thigh, hip and hip, usually deep pain and soreness, especially after repeated deep squatting, standing up from a sedentary position, and walking long distances. Some patients are unable to walk freely, and even have difficulty wearing shoes and socks, and some patients may be affected by driving. Repeated friction and collisions can cause glenoid labral damage, and in severe cases, the torn labrum becomes embedded in the joint space, causing pain and interlocking. It is difficult for the torn labrum to heal on its own, and if it is not repaired in time, the damage may continue to expand. The lack of a “cushion” to protect the hip joint will accelerate cartilage wear and tear, leading to osteoarthritis and, in severe cases, even the need for total hip replacement. The treatment of hip impingement syndrome includes conservative treatment and surgery. For patients with mild lesions, minor clinical symptoms, little impact on daily work and life, and low demand, conservative treatment includes lifestyle changes, exercise changes (running and jumping intense exercise → slow walking and swimming and other soothing exercises) and oral non-steroidal anti-inflammatory painkillers. For patients with more severe lesions and obvious clinical symptoms (especially limp, short walking distance, difficulty in pain relief, interlocking popping, etc.), which affect daily work life, surgical treatment can be considered, including arthroscopic minimally invasive surgery and open surgery.
