Which Knee bones?

Knee is a tricompartmental synovial condylar joint which contains following knee bones:

  1. Femur- commonly known as thigh knee bone which joins lower limb from hip to knee joint.
  2. Tibia- Commonly known as shin bone which runs from knee to ankle.
  3. Patella- Commonly known as kneecap bone which is in front of knee joint.






Femur(Thigh Bone)

Femur also known as thigh bone among general population is a longest bone of the human body and also is the strongest bone in human body.

Femur joins the shin bone(tibia) and knee-cap bone(patella) among other knee bones to form a knee joint anatomy.

Knee joint is formed by rounded protrusion on lower end of femur or thigh bone also called femoral condyles. There are 2 condyles which articulates with tibia bone to form tibio-femoral joint.

Patella sits on top of lower end of femur in patello-femoral grove.

The margins of this lower of femur are lined by hyaline cartilage.


Tibia(Shin bone)


Tibia (Shin Bone) is at lower part of knee joint anatomy and basically articulate with femoral condyles to form a tibio-femoral joint.

Upper flat surface of Tibia is known as tibial plateau and is the part of knee bones where all the main ligaments of knee joint attaches. Its also constant contact point for femoral condyles.

Tibia is a long shin bone which also articulates with small long bone called Fibula to form Tibio-fibular joints. They are also integral component that makes knee bones.

Patella(Knee cap)

Patella commonly known among general population is a knee cap is a small triangular knee bones at the front of knee joint.


Patella is a sesamoid bone and it has got two surfaces- anterior and posterior. Posterior surface of patella is lined by cartilage and is under constant wear and tear from repetitive knee forces. When this posterior surface cartilage is eroded it causes knee cap pain as well.



So Knee bones are different bone structures which makes an osteology(science of bone) compartment of knee joint and plays important role in understanding knee pain related issues and also helps doctor understand any bone related issues as well. They have direct attachments for knee muscles, knee ligaments, knee cartilages and bursa.
