Ligaments of the knee joint

anterior cruciate ligament Ligaments are tough bands of fibrous tissue that connect bone to bone and provide stability to the joints. There are four ligaments involved in the knee joint. Two ligaments are present inside the knee joint (CRUCIATE LIGAMENTS) and two ligaments are present on the outside (COLLATERAL LIGAMENTS).

Cruciate Ligaments
Cruciate ligaments (also cruciform ligaments) are pairs of ligaments arranged like the letter X.


» Anterior Cruciate Ligament (ACL):
anterior cruciate ligament injuryIt lies within the knee joint and is about 4cm long, binding the tibia to the femur. The ACL prevents forward slipping of the tibia on the femur and stops hyperextension of the knee. The ACL runs through a special notch in the femur called the intercondylar notch and attaches to a special area of the tibia called the tibial spine. Read More>>


» Posterior Cruciate Ligament (PCL):
posterior cruciate ligamentThe posterior cruciate ligament (PCL) lies just behind the ACL and similarly connects the femur and tibia but runs in a different direction. The PCL is the primary stabilizer of the knee and the main controller of how far backward the tibia moves under the femur. This motion is called posterior translation of the tibia.


Collateral Ligaments
The collateral ligaments are extra-articular (outside the knee joint). The medial collateral ligament is present on the inner side and lateral collateral ligament is present on the outer side of the knee. Read More>>

» Medial Collateral Ligament (MCL):

Injuries to the MCL are usually caused by contact on the outside of the knee & are accompanied by sharp pain on the inside of the knee. Being fairly large & vascular the medial collateral ligament has an excellent ability to heal. Read More>>


» Lateral Collateral Ligament (LCL):
lateral collateral ligament injuryThe lateral collateral ligament (LCL) connects the femur to the fibula and stabilizes the outer side of the knee. Injury to lateral collateral ligament : (LCL) occurs when the force is applied to the inner part of the knee and the knee buckles outwards. Read More>>
