Anatomy of the Knee
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 largest joint in the body, the knee is also one of the most easily injured. Problems with any part of the knee's anatomy can result in knee pain, stiffness, and difficulty walking.
This article details knee anatomy. It explains the different parts that make up the knee joint, how the knee works, and common knee problems.
Bones Around the Knee
Three important bones come together at the knee joint:
- The tibia (shin bone)
- The femur (thigh bone)
- The patella (kneecap)
A fourth bone, the fibula, is located just next to the tibia and knee joint, and can play an important role in some knee conditions.
The tibia, femur, and patella all are covered with a smooth layer of cartilage where they contact each other at the knee joint.
There is also a small bone called a fabella, that is often located behind the knee joint. The fabella is a type of bone called a sesamoid bone (meaning it sits within a tendon). It's of little consequen

The knee joint is a hinge type synovial joint, which mainly allows for flexion and extension (and a small degree of medial and lateral rotation). It is formed by articulations between the patella, femur and tibia.
In this article, we shall examine the anatomy of the knee joint &#; its articulating surfaces, ligaments and neurovascular supply.

The knee joint consists of two articulations &#; tibiofemoral and patellofemoral. The joint surfaces are lined with hyaline cartilage and are enclosed within a single joint cavity.
- Tibiofemoral – medial and lateral condyles of the femur articulate with the tibial condyles. It is the weight-bearing component of the knee joint.
- Patellofemoral – anterior aspect of the distal femur articulates with the patella. It allows the tendon of the quadriceps femoris (knee extensor) to be inserted directly over the knee &#; increasing the efficiency of the muscle.
As the patella is both formed and resides within the quadriceps fe
Knät är kroppens största led men också en av de mest känsliga. Leden är nämligen uppbyggd av flera komponenter som gör den mottaglig för skador. De fyra främsta komponenterna, som tillsammans utgör knäts anatomi, är skelettben, brosk, ledband och menisker. Runt knäleden finns en ledkapsel och sedan muskler. Knäskålen ligger inne i den stora lårmuskeln på framsidan och stabiliserar leden. Lårben och underben binds samman av ledband och muskler. När det pratas om knän talas det även ofta om ligament, som är ett annat ord för ledband.

Detta beror på att knät är uppbyggt med olika ledband som hjälper till att hålla ihop leden. Inuti knät finns två strama ledband som kallas för korsband. De stabiliserar ledens rörelse framåt och bakåt. På sidorna av knät sitter en annan typ av ledband, sidoledbanden eller kollateralligamenten, vars syfte
Click to View Larger Image The knee joint is one of the strongest and most important joints in the human body. It allows the lower leg to move relative to the thigh while supporting the body's weight. Movements at the knee joint are essential to many everyday activities, including walking, running, sitting and standing. 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. The patella lies in front of the femur on the anterior surface of the knee with its smooth joint-forming processes on its posterior surface facing the femur. The joint-forming surfaces of each bone are covered in a thin layer of hyaline cartilage that gives them an extremely smooth surface and protects the underlying bone from damage. Between the femur and tibia is a figure-eight-shaped layer of tough, rubbery fibrocartilage known as the meniscus. The meniscus acts as a shock absorber inside the knee to prevent the collision of the leg bones during strenuous
