What Anatomy Articulates To Form The Knee Joint?

What are the three articulations of the knee joint?

The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or “kneecap”, and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations

What are the 2 bones which articulate to form the knee joint?

The Knee is a hinge joint made up of two bones, the thigh bone (femur) and the shinbone (tibia). There are two round knobs at the end of the femur called femoral condyles which articulate with the flat surface of the tibia called the tibial plateau.

Which bones make up the knee joint?

The knee consists of three bones: femur – the upper leg bone, or thigh bone. tibia – the bone at the front of the lower leg, or shin bone. patella – the thick, triangular bone that sits over the other bones at the front of the knee, or kneecap.

What muscles articulate the knee?

The quadriceps muscles of the knee meet just above the patella and attach to it through a tendon called the quadriceps tendon. The patella further attaches to the tibia through a tendon called the patella tendon. The quadriceps muscle, quadriceps tendon and patellar tendon all work together to straighten the knee.

How does the knee work as a joint?

The knee is a hinge joint, formed where the thighbone (femur) and the shinbone (tibia) meet. Healthy cartilage absorbs stress and allows the knee to bend easily. Muscles power the knee and leg for movement. Tendons attach the muscles to the bones.

What is the side of your knee called?

Knee pain is common and can be a symptom of many different knee conditions or injuries. The inside of your knee, also called the medial knee or the medial compartment, is the area of the knee that’s closest to your opposite knee. Medial knee pain typically occurs because of a deterioration of cartilage.

What causes pain on the inner side of the knee?

Inner knee pain can be the result of an injury caused by a sport or exercise, such as running, that puts a strain on the knee joint. This pain can also be caused by trauma, where a person has fallen on their knee or been in an accident. This condition occurs due to inflammation in a tissue in the knee called a bursa.

Why does the side of my knee hurt?

For instance, pain on the inside or medial side of the knee (the side closest to the other knee ) can be caused by medial meniscus tears, MCL injuries, and arthritis, whereas pain on the outside of the knee, or lateral side, can be caused by lateral meniscus tears, LCL injuries, IT band tendonitis, and arthritis.

What is the muscle on the side of your knee?

The MCL and the LCL sit on the sides of the knee, and they help give stability to the knee if your knee gets hit from the sides. The ACL and PCL are inside the knee and cross each other as they run front to back and vise versa. These 2 ligaments are responsible for giving the knee stability from front to back.

What does it mean when the back of your leg hurts behind the knee?

Some of the most common causes of pain behind the knee (posterior knee pain ) include, Baker’s cyst, arthritis, infection, injury, tumor, or deep vein thrombosis. Since the knee is the largest and most complex joint in the body, it makes sense that it might hurt sometimes.

What is the most common knee injury?

ACL injuries are one of the most common types of knee injuries and account for about 40 percent of all sports-related injuries. An ACL injury can range from a small tear in the ligament to a severe injury –when the ligament completely tears or becomes separated from the bone itself.

What are the 4 main ligaments of the knee?

The four main ligaments in the knee connect the femur (thighbone) to the tibia (shin bone), and include the following:

  • Anterior cruciate ligament (ACL).
  • Posterior cruciate ligament (PCL).
  • Medial collateral ligament (MCL).
  • Lateral collateral ligament (LCL).

What do collateral ligament do at the knee?

The medial collateral ligament’s main function is to prevent the leg from extending too far inward, but it also helps keep the knee stable and allows it to rotate. Injuries to the medial collateral ligament most often happen when the knee is hit directly on its outer side.

  • Pain, often sudden and severe.
