Hinge Joint- Knee
The knee joint is the largest joint in the body, consisting of 4 bones and an extensive network of ligaments and muscles.
What is the scientific name of this joint?
The knee joints that make up the knee are split into three parts. The femur meets the tibia to form the main knee joint. This joint has an inner called medial and an outer called lateral compartment. The patella joins the femur to form a third joint, called the patellofemoral joint. The patella protects the front of the knee joint.
What bones make up this joint?
The Bones that make up the knee are the femur, the patella, the fibula and the tibia.
They all connect to the joint and the patella protects the joint.

o Lateral collateral ligament (LCL)-
The ligament that gives stability to the outer knee.
o Patellar ligament- attaches to the kneecap to the tibia.
Tendons-
There are two main tendons of the knee and they help stabilise the knee-
The quadriceps tendon connects the quadriceps muscles of the thigh to the kneecap and provides the power for straightening the knee. It also helps hold the patella in the patellofemoral groove in the femur. The patellar tendon connects the kneecap to the tibia.
Cartilages- o Medial meniscus- made of fibrous, crescent shaped cartilage and attached to the tibia, on the inside of the knee.
o Lateral meniscus- made of fibrous, crescent shaped cartilage and attached to the tibia, on the outside of the knee.
o Articular cartilage- is on the ends of all bones in any joint.
Muscles-
The muscles in the leg keep the knee stable, well aligned and moving.
The quadriceps and hamstrings, they are two of the main muscle groups-
The quadriceps are made up of 4 muscles on the front of the thigh and are responsible for straightening the knee by bringing a bent knee to a straight
