The patella is a small, triangular bone which sits in the quadriceps muscle at the front of the knee. ![]() When looking at the anterior aspect of knee joint anatomy, you will find the patella (kneecap). You can find out more in the knee swelling section. If the joint capsule is damaged, swelling is no longer confined to the joint so tends to actually be less obvious. This is like a bag that surrounds the joint containing synovial fluid to nourishĪnd lubricate the knee allowing it to move smoothly and freely.Īny swelling that occurs in the joint is contained inside the capsule, which is why injuries can cause the knee to "balloon". Knee Anatomy Joint CapsuleĪnother important part of knee anatomy is the joint capsule. In the knee bursa anatomy section we look at each of the bursa, where they are, what they do, how they get injured and how to make a full recover from bursitis. If there is excessive friction on the bursa, usually due to muscle weakness, tightness or repetitive pressure, then the bursa gets inflamed, known as knee bursitis.

Now let's have a look at knee bursa anatomy.
