Posterolateral Knee Injury

The knee joint is supported by a group of soft tissues - tendons and ligaments. In case of a Posterolateral (PLC) injury, these structures tend to break away from their normal position and cause discomfort in the knee. Any external stress to the joint may also damage or weaken these bony structures causing instability and loss of joint function. PLC injuries may be classified into different grades depending on the severity and gap size between the joints. The condition generally affects athletes involved in contact sports like football, basketball, ice hockey etc.

  • Grade 1- gap size of about 3-5 mm
  • Grade 2- gap size of 5-10 mm
  • Grade 3- gap size of more than 10mm
