ABSTRACT
The anterior cruciate ligament (ACL) is an important stabiliser of the knee and is commonly torn in sports injuries. Common indications for imaging after ACL reconstruction include persistent symptoms, limitation of motion and re-injury. Important postoperative complications include graft failure, impingement, arthrofibrosis and graft degeneration. This article aimed to familiarise the radiologist with magnetic resonance (MR) imaging appearances of properly positioned intact ACL grafts and to provide a comprehensive review of MR imaging features of complications following ACL reconstruction.

A 48-year-old woman presented with progressive left hip pain over six months, along with left lower limb weakness for two weeks. Magnetic resonance imaging of the left hip showed narrowing of the left ischiofemoral space, oedema of the left quadratus femoris muscle and left sciatic nerve, and mild bone marrow oedema of the left ischial tuberosity. The diagnosis of left ischiofemoral impingement syndrome was made. The imaging features of ischiofemoral impingement syndrome and the associated aetiologies and complications are discussed.
