Abstract

Although it is well known that extension block in the injured knee is usually attributed to a meniscus tear or anterior cruciate ligament rupture, it is vary rare to cause mechanical extension block by the torn posterior cruciate ligament. We report a case of posterior cruciate ligament partial rupture who presented persistent extension block caused by a nodule formation in a 12-year-old boy after knee trauma and was treated with arthroscopic resection of the nodule.
