Research progress in complications of hip arthroscopy

Hip arthroscopy has become a routine treatment for the localized hip lesions. With the rapid development of arthroscopy, the number of surgeries has increased greatly. Though hip arthroscopy is considered as low risk operation, its complications have been constantly reported and noted. There are two major types in hip arthroscopy surgeries: conventional operative complications and special complications. Conventional operative complications include venous thromboembolism, hemorrhage, and pain. Special complications are associated with arthroscopic techniques and local anatomical structures of the hip, such as the perineal nerve, the lateral femoral cutaneous nerve, the acetabular labium or the iatrogenic injury of the cartilage surface of the femoral head. Hip arthroscopy has obvious advantages such as small surgical wound and rapid recovery, but its complications can not be ignored. Joint surgeons must fully recognize it and keep vigilant so as to avoid complications as much as possible. This review will systematically elaborate the complications of hip arthroscopic surgery from general and special aspects so as to provide ideas for reducing the occurrence of complications in hip arthroscopic surgery.
