What is Osteoarthritis?
Osteoarthritis (also known as arthrosis, osteoarthrosis or OA) is a degenerative disease, which causes the cartilage that protects the ends of your bones to wear down, causing pain, swelling and problems with mobility. This is a result of the protective fluid in your joint losing its shock-absorbing abilities, causing bones to rub against each other.
The condition is sometimes referred to as 'wear and tear' and causes the bones to thicken and stick out, a symptom know as spurs. OA will also cause the capsules and ligaments, bands that hold the joint together, to thicken along with extra fluid in the joint resulting in swelling. These symptoms are a result of the body attempting to repair the joint; something that can sometimes occur relatively pain free. In severe cases, the cartilage can become so thin that it doesn't cover the end of the bone leaving it exposed and consequently changing the shape of the joint due to the excessive wearing away of the bone and the presence of bony spurs.
Any joint in the body can be affected by OA but the most common damage is found in the knees, hips, lower back, neck, fingers and toes.
For further information on the condition, take a look at the "What is Osteoarthritis of the Knee" guide from Arthritis Research UK which offers a comprehensive review of the condition and how the charity can help sufferers.
Who can be affected?
There is no direct cause of OA and almost anyone can get the condition, including children. However, you’re more likely to suffer OA if you fall under any of the following categories:
- You are a woman
- You are 40 years old or older
- Your parents have had OA
- You are overweight
- You have had a previous joint injury
- You are in a physically demanding job
- Your joints have been affected by another disease, for example, gout or rheumatoid arthritis

Types of Osteoarthritis
Osteoarthritis is the most common type of arthritis in the UK. Other types of arthritis that cause pain and inflammation in the joints include:
- Ankylosing spondylitis
- Cervical spondylosis
- Enteropathic arthritis
- Psoriatic arthritis
- Rheumatoid arthritis
- Reactive arthritis
- Secondary arthritis
- Polymyalgia rheumatica

Common symptoms of Osteoarthritis
The most common symptoms of OA are pain and stiffness in the joint, with some people experiencing swelling, tenderness and a grating sound when using the damaged joint.
The severity of symptoms differs from person to person with some feeling mild discomfort that can come and go and others suffering continuous debilitating pain, which can make it difficult to go about their daily activities.
If you’re showing the symptoms of OA, you should make an appointment with your GP who can diagnose the condition and prescribe relevant treatment.

Diagnosing and treating Osteoarthritis
Your GP can usually diagnose OA based on your symptoms and a physical examination of your joints. However, your doctor may also ask for a blood test, X-ray or a Magnetic Resonance Imaging (MRI) scan. For more information on diagnosing OA, visit our ‘Diagnosis’ page.
Even though OA is a long-term, incurable condition, treatments can be prescribed to ease the symptoms, improve the condition and prevent it from getting worse. There are a number of treatment options available, including non-surgical solutions, such as exercising, bracing and medication, as well as surgical solutions, like arthroscopy, tibial osteotomy and full knee replacements.
