There are three bones that come together at the knee joint. The shin bone (tibia), the thigh bone (femur), and the kneecap (patella) are each important parts of the knee joint. A fourth bone, the fibula, is located just next to the shin bone (tibia) and knee joint, and can play an important role in some knee conditions. The tibia, femur, and patell...
There are two types of cartilage of the knee joint. Articular cartilage is the smooth lining that covers the end of the bone. When the smooth articular cartilage is worn away, knee arthritis is the result. Cartilage is a resilient structure that resists damage, but when injured it has a difficult time healing.
The other type of cartilage in the knee joint is called the meniscus. When people talk about 'cartilage tears,' they are usually referring to a meniscus tear. The meniscus is a shock absorber that sits between the end of the thigh bone and the top of the shin bone. One ligament is on each side of the knee joint; the medial collateral ligament on th...
Muscles propel the knee joint back and forth. A tendon connects the muscle to the bone. When the muscle contracts, the tendons are pulled, and the bone is moved. The knee joint is most significantly affected by two major muscle groups. The quadriceps muscles provide strength and power with knee extension (straightening) and the hamstrings muscles a...
The synovium is the lining of the joint space. The synovium is a layer of tissue that defines the joint space. The synovial cells produce a slippery, viscous fluid called synovial fluid within the joint. In conditions that cause inflammation of the joint, there can be an abundance of synovial fluid produced, that leads to swelling of the knee joint...
A bursa is a structure in your body it is placed between Two moving parts. In your knee, there is a prominent bursa just in front of your knee, and underneath the skin. The bursa functions as a means to allow for smooth movement between these two structures (skin in the bone). There are actually hundreds of bursa spread throughout your body, but if...
- Knee Bone Anatomy. The most basic component of knee joint anatomy are the bones which provide the structure to the knee. There are four knee bones that fit together to make two different knee joints
- Knee Joint Cartilage Anatomy. A really important part of knee joint anatomy is the cartilage. There are two different types of knee cartilage: Articular Cartilage: a thin layer of cartilage which lines the surfaces of the knee joints.
- Knee & Leg Muscle Anatomy. When looking at knee and leg muscle anatomy, the main knee muscles controlling the leg are the: Quadriceps: four muscles on the front of the thigh which straighten the knee - rectus femoris, vastus medialis, vastus lateralis and vastus intermedius.
- Knee Ligament Anatomy. When thinking about knee joint anatomy in terms of stability, it is the knee ligaments that are most important as they are the main stabilising structures of the knee preventing excessive movements and instability.

Learn about the structure and function of the knee joint, a synovial hinge joint formed by the femur, tibia, and patella. Explore the bones, cartilage, ligaments, bursae, and muscles of the knee with interactive 3D models.
Oct 30, 2023 · The knee joint is a synovial joint that connects three bones; the femur, tibia and patella. It is a complex hinge joint composed of two articulations; the tibiofemoral joint and patellofemoral joint.

Bones and Joints. The knee is the meeting place of two important bones in the leg, the femur (the thighbone) and the tibia (the shinbone). The patella (or kneecap, as it is commonly called) is made of bone and sits in front of the knee. The knee joint is a synovial joint.
