Abstract: Objective:Discuss the choice of operative methods and difficulties of ipsilateral inguinal hernia after total hip arthroplasty.Methods:From March 2010 to May 2018，21 patients with history of total hip replacement and ipsilateral new inguinal hernia were retrospectively reviewed.The anatomical characteristics and surgical methods of the patients were analyzed and summarized.Results:Laparoscopic transperitoneal extraperitoneal hernia repair（TAPP）was performed in 7 cases and laparoscopic total extraperitoneal hernia repair（TEP）in 2 cases，Open surgery was performed in 12 cases，with Lichtenstein operation.There were 17 patients with different degrees of pubicbladder space adhesion，difficult to separate the anteromedial peritoneal space，difficult to fully expose the pubic ramus.However，Lichtenstein operation has clear clearance and smooth operation.Conclusion:Patients with ipsilateral inguinal hernia after total hip arthroplasty may have different degrees of pubicbladder space adhesion.Lichtenstein was chosen as the main surgical method to reduce the large area separation of pubicbladder space.
