Knee ligaments are bands of tissue that connect the thigh bone in the upper leg to the lower leg bones. There are four major ligaments in the knee: ACL, PCL, MCL and LCL. Injuries to the knee ligaments are common, especially in athletes. A sprained knee can range from mild to severe.
The four main ligaments in the knee are: Medial Collateral Ligament: found on the inner side of the knee. Lateral Collateral Ligament: found on the outer side of the knee. Anterior Cruciate Ligament: found in the middle of the knee. Posterior Cruciate Ligament: found in the middle of the knee.
In the knee ligament anatomy section we look at each of the different ligament in-depth including how they work, what their role is, how they get damaged and how to make the best recovery from ligament injuries.
Knee anatomy involves more than just muscles and bones. Ligaments, tendons, and cartilage work together to connect the thigh bone, shin bone, and knee cap and allow the leg to bend back and forth like a hinge.
The ligaments of the knee joint can be divided into two groups; extracapsular ligaments and intracapsular ligaments. These ligaments connect the femur and tibia, holding them in place, providing stability, and preventing dislocation.
There are two types of ligaments in your knee: Collateral ligaments: The two collateral ligaments are like straps on opposite sides of your knee. The medial collateral ligament (MCL) is on the inner side of your knee.
The knee, also known as the tibiofemoral joint, is a synovial hinge joint formed between three bones: the femur, tibia, and patella. Two rounded, convex processes (known as condyles) on the distal end of the femur meet two rounded, concave condyles at the proximal end of the tibia.
Ligaments. The major ligaments in the knee joint are: Patellar ligament – a continuation of the quadriceps femoris tendon distal to the patella. It attaches to the tibial tuberosity. Collateral ligaments – two strap-like ligaments. They act to stabilise the hinge motion of the knee, preventing excessive medial or lateral movement
Introduction. A diarthrodial joint that allows simultaneous rotation and translation. ACL. Function. prevents anterior translation of the tibia relative to the femur. Anatomy. extrasynovial but intracapsular. origin. lateral femoral condyle. PL bundle originates posterior and distal to AM bundle (on femur) insertion. broad and irregular.
Inside the knee joint, two other important ligaments stretch between the femur and the tibia: the anterior cruciate ligament (ACL) in front, and the posterior cruciate ligament (PCL) in back. The MCL and LCL prevent the knee from moving too far in the side-to-side direction.
