The posterolateral corner of the knee. Anatomy, biomechanics and management of injuries.

The structures within the posterolateral corner of the knee have recently been "re-discovered" providing a very important role in maintaining the stability of the knee. Injury to the posterolateral corner is not common but neither is it rare; it is usually damaged in combination with rupture of one of the cruciate ligaments in direct and indirect trauma to the knee. When reconstructing a knee to restore stability following such injuries, it is important to recognise damage to the posterolateral corner so that this can be corrected.

The immature athlete.

The skeletally immature athlete poses unique problems in diagnosis and treatment of injuries to the extensor mechanism of the knee. An accurate and detailed history and physical examination of the knee are essential for making a specific diagnosis and formulating an appropriate treatment plan. This article presents an overview of acute and chronic injuries of the extensor mechanism of the knee that are unique to skeletally immature athletes.
