Knee Injuries – MCL Tear and LCL Tear Injury

Information About MCL Tear and LCL Tear Injuries

Brockton Personal Injury Attorneys

Knee InjuriesThe medial collateral ligament (MCL) and the lateral crucial ligament (LCL) are two of the four ligaments that stabilize the knee joint. Both are located on the sides of the knee. The MCL is located on the inside of the knee while the LCL is located on the outside of the knee. The MCL and LCL, also known as the collateral ligaments, control the sideways movement and stability of the knee.

The knee relies heavily on these ligaments for stability and as a result both the MCL and LCL are easily injured. The MCL is injured more often than the LCL. MCL tears usually accompany an injury to the meniscus. Other structures in the knee joint usually sustain an injury when the LCL is injured. An LCL tear is usually accompanied by an ACL tear or a PCL tear.

What Causes an MCL Tear and LCL Tear

The MCL and LCL are injured in several ways. However, most tears require great force:

  • A direct blow that forces the knee sideways.
  • MCL tears are usually the result of a blow to the outside of the knee. The ligament tears when the knee is force inward in the direction of the other knee.
  • LCL tears are usually the result of a blow to the inside of the knee.


  • Pain located on the inside and or outside of the knee. Pain on the inside of the knee for MCL injuries and pain on the outside of the knee for LCL injuries.
  • Swelling might appear in some case but might not appear in other cases.
  • Knee Instability or a feeling that your knee has giving way.
  • Lack of side to side range of motion or flexibility.


The doctor will perform a physical examination on the knee to determine if there is a strain, tear or rupture. The doctor will perform a test called the varus knee test by applying slight pressure to the inner knee joint. The patient will be sent for an MRI which will pinpoint the extent of the injury and rule out injuries to other structures in the knee. X-Rays could also be ordered to determine if the femur or tibia sustained a fracture.
