Papers of the Week

A 19-year-old male amateur footballer was referred to our center with complaints of relapsing and remitting pain, swelling, and reduced range of motion of the left knee. History, radiological, and laboratory findings were unrevealing, except for chronic synovitis. On arthroscopy, a 3.3 × 0.3-cm thorn was found embedded in the anteromedial aspect of the anterior cruciate ligament and was carefully removed. The postoperative course was uneventful.
