INJURY TITLE

Posterior Lateral Corner ‘PLC’ injuries to the knee.

 

INJURY OVERVIEW

Problems with the structures at the back and outside of the knee.  The structures there are very influential in controlling unwanted rotation in the knee. 

 

INJURY IN-DEPTH INFORMATION

The most common mechanisms of injury to the posterolateral corner involve an over-straightening injury (contact or non-contact), direct trauma to the knee, and noncontact sideways force to the knee.  Injuries to the posterolateral corner can be debilitating to patients and require prompt diagnosis and treatment to avoid long term consequences.  Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL).

 

COMMON SIGNS & SYMPTOMS

  • Pain
  • Instability in the knee
  • Possible pins and needles and numbness (nerves can be involved in such injuries)

 

HOW IS IT ASSESSED

  • Clinical examination to assess structural integrity of the knee joint (an injury to the PLC rarely happens in isolation)
  • X-Ray and MRI to assess the extent of the damage

 

GENERAL TREATMENT

  • Treatment depends largely on the degree of damage to the area
  • Mild injuries can be manage with focused and individualised rehabilitation
  • More sever injuries would require surgical opinion and possible intervention

 

Exercise Videos: i.e.

  • Rotator cuff strengthening
  • Pec stretch
  • etc

Put an ‘X’ next to each health professional that most commonly deals with this injury.

i.e. tennis elbow would be Physio and Medic as injections are common, whereas for muscular LBP it would be Physio and not Medic as they would just refer them to a Physio.
