Knee Anatomy

Keeping your knees healthy is key to keeping a healthy and active lifestyle. As one of the largest joints in your body it plays a vital role in your day-to-day life.

The knee has three main parts:

The knee is made up of the lower end of the thighbone (femur), the upper end of the shinbone (tibia), and the kneecap (patella).

Large ligaments also help connect the tibia and femur together. They give the knee its strength and stabilise the whole knee.

The surface of the bones are covered with a smooth layer called the “articular cartilage”. This can become roughened as a result of injury or arthritis.

To help support the joint there is another type of cartilage, known as the meniscus. This is a half moon shaped cartilage that sits in-between the bones. It acts as a shock absorber and stops the different parts of the knee rubbing together.

The cartilage of the knee is lubricated with a fluid that is released by the synovial membrane. This fluid covers the surface of the knee, without it you wouldn’t be able to freely bend your knees. A healthy knee will experience no friction.

It is when these three parts stop working together that problems arise. This can be due to disease or injury. Symptoms can include pain, muscle weakness or disability, which is why it is important to keep your knees healthy and see your orthopaedic surgeon as soon as possible when you experience any of them.
