Knee Ligament Injury and Treatment

One of the more common injuries to the knee ligament occur as an ACL injury. This is when the anterior cruciate ligament of the knee gets torn or sprained during physical activity. At the time of injury, it is common to hear a popping localised in the knee, at which point rapid swelling and pain follow suite. The treatment of any knee ligament injury will require rest and rehabilitation. How long one must commit to the healing process will be determined by the severity of the injury. 

What are the ligaments of the knee?

Within the knee are three bones that serve to attach the knee joint to the thigh bone. Ligaments, which are strong band-like tissues, connect these three bones to each other, keeping the knee bone in place.

On the sides of the knee, inside and outside are the collateral ligaments. These serve to protect and control the knee as it moves sideways.

  • Inside Knee: Medial Collateral Ligament (MCL)
  • Outside Knee: Lateral Collateral Ligament (LCL)

Forming a criss-cross inside the knee are the cruciate ligaments, they act to protect and control the motion of the knee as it moves back and forth.

  • Front of Knee: Anterior Cruciate Ligament (ACL)
  • Back of Knee: Posterior Cruciate Ligament (PCL)

The knee is a relatively vulnerable region of the body, which suffers from injury frequently. When there is an injury to a knee ligament, it is usually referred to as a “sprain”. Sprains are graded by the severity of the injury. When injury does occur, it is a particularly timely process if the severity of the injury is significant. To hasten the recovery time, injury repair and recovery peptides may offer support.


Common Causes of Knee Ligament Injury


  • Sudden change of motion / direction or stopping suddenly
  • Pivoting with your foot stationary
  • A bad landing from a jump
  • A collision that causes a direct hit to the knee.


Prevent knee injury through proper training and exercise

To reduce the liklihood of sustaining a knee ligament injury, specific exercises and training techniques can be highly effective. Exercises that focus on promoting muscular strength within the leg are key to preventing further injury. One should practice landing from jumps, ensuring correct technical placement of the knee.  Training can also be focused on how best to stop, shift direction and pivot for injury prevention. Training this way means that eventually one’s landing technique and motion will become second nature.

Preventing a knee injury from occuring again, one should also commit to the specified healing time and not resume activity. Not giving yourself adequate time to repair, sets you up for further damage and a weakened constitution.
