title: Recurrent hematomas within the iliopsoas muscle caused by impingement after total hip arthroplasty.
abstract: Impingement of the iliopsoas muscle after total hip arthroplasty is a potential cause of postoperative groin pain. In addition, hematoma within the iliopsoas sheath has been documented as a cause of groin pain in patients on long-term anticoagulation. We present the case of a patient on long-term anticoagulation presenting after total hip arthroplasty with recurrent, symptomatic iliopsoas sheath hematomas. We believe this was due to iliopsoas impingement caused by a malpositioned acetabular component. His pain was relieved after revision of the acetabular component and debridement of the inflamed psoas tendon.
