What Are The Symptoms Of Osgood-Schlatter Disease
If you suffer from Osgood-Schlatter disease you will feel pain and tenderness in the bony prominence at the front of the tibia (shin bone) just below the knee.
This area is known as the tibial tuberosity. Early on there may be just pain, before a bump develops. The pain is worse with exercise, better with rest.
What Causes Osgood-Schlatter Disease?
The condition probably arises as a result of repetitive stresses, (overuse) where the patellar tendon joins the shin bone. The stresses lead the body to try to heal the area by creating new bone, called an apophysis.
X-rays may reveal this separate, prominent piece of bone. You can see this clearly on the x-ray shown here.
What Is Bursitis?
A bursa is a lubricated sac of tissue which lies between two structures allowing them to glide easily over each other.
There are several bursa around the knee. For example, there is one which lies between the kneecap and the skin (the pre-patellar bursa – seen in the first image here), and one which lies between the lower end of the patellar tendon, the bony prominence at the front of the tibia and the skin (the infra-patellar bursa – the image in the next section below).
The bursa may become inflamed and irritated due to constant friction between the skin and underlying area. It may swell up with fluid, sometimes quite dramatically. This is particularly common in some professions involving kneeling (e.g. carpet fitting, joinery, plumbing). You may see pre-patellar bursitis and infrapatellar bursitis described by the old-fashioned terms ‘housemaid’s knee’ and ‘clergyman’s knee’ respectively.
What Is Runner’s Knee?
Sometimes called ITB syndrome or runners knee.
Runner’s knee, ITB or ilio-tibial band friction syndrome affects the firm, broad band of tissue which you may feel running down the lower part of the outer thigh towards the knee.
Repetitive stresses and irritation between the ITB and the underlying structures can cause pain. This is usually made worse with certain vigorous activities, especially running.
