About knee pain

Your joints are involved in almost every activity you do. Simple movements such as walking, bending, and turning require the use of your hip and knee joints. Normally, all parts of these joints work together and each joint moves easily and without pain. But when a joint becomes diseased or injured, the resulting pain can severely limit your ability to move and work. Pain in your knee can be debilitating, making it difficult for you to walk, climb stairs, or even pick up an object from the floor. It can limit your freedom of movement and ability to function independently.

There are many treatments that may relieve knee pain, helping you move more freely and rediscover some of the physical activities you once enjoyed. If you’re feeling pain in your knee, the first thing you should do is ask your GP for advice. There are a number of treatment options that he/she may recommend.

 

How does the knee work?

Your thigh bone (femur) turns on the upper end of the shin bone (tibia), while your kneecap (patella) slides in a groove on the end of the thigh bone. Bands of tissue called ligaments connect these two bones and help keep the knee joint steady. The long muscles on the front of the thigh, called quadriceps, help strengthen the knee.

A smooth substance (called articular cartilage) covers the surface of the bones where they touch each other within the joint, and acts as a cushion between the bones. A thin, smooth tissue liner (called the synovial membrane) covers the rest of the surfaces of the knee joint, and provides fluid that lubricates the joint and prevents your bones from rubbing against
