Knee Ligament Injury (Medial / Lateral Ligament Injury)

What is Knee Ligament Injury (medial /lateral ligament injury)?

The Medial and Lateral Ligaments are situated on the inside (medial) and outside (lateral) of your knee. They both contribute to knee stability especially in an active knee in preventing sideways movement of the knee. They also assist to a lesser degree in preventing pivoting of your knee.  You may hear a ‘crack’ or feel a ‘pop’ in your knee if you have a major tear in one of these ligaments. Both of these ligaments are injured from different movements involving your knee either moving ‘outwards’ or ‘inwards’. In some cases the immediate pain you will feel may subside quickly however you will not be stable on your knee and should NOT continue in sport. 

Your knee may not swell if you have injured these ligaments in isolation. You may have also injured your cartilage or other ligaments around the knee and this will also determine what management is best for you. You should consult our practitioners immediately for assessment or for after hours assistance for direction.

How long will it last?

Medial and Lateral Ligament tears do have a capacity to heal. Rehabilitation following either ligament being injured is advised for a full recovery. Practitioners follow you through to the completion of your program and provide you specific functional tests to clear you to resume playing sports. Medial and Lateral Ligament injury may take between 3-6 weeks for recovery, if there is no other injury to your knee and longer if you have complete disruption (grade 3 tear).


The symptoms of Knee Ligament Injury are:

  • ‘Crack’ or ‘pop’ on the inside or outside of your knee.
  • Pain and weight bearing, sideways movement or twisting.
  • Stiffness in the knee after a few days.
