Ostenil® is a treatment for the symptoms of osteoarthritis. It can be used in the knee, or in any of the other joints in the body that are classified as ‘synovial’. These injections are administered by our specialist physiotherapists who hold an injection therapy qualification.
A synovial joint is one in which the ends of the bones are enclosed in a capsule containing a thick, slippery liquid called synovial fluid. The capsule is made of strong, fibrous tissue and is lined with a membrane called the synovial membrane. The bone ends are covered in a smooth layer of a tough, rubbery substance known as cartilage.
The synovial fluid in the joint capsule has four important functions:
The most important component of synovial fluid is a substance called hyaluronic acid. It is this substance that lets synovial fluid perform its four different functions all at the same time.
The hyaluronic acid in synovial fluid does not stay there for a whole lifetime but is continuously broken down and replaced. Normally, there is an exact balance between the breakdown of old hyaluronic acid and the production of new hyaluronic acid. In osteoarthritis however, this balance is disturbed and breakdown happens faster than production. As a result, the synovial fluid becomes more watery and stops working properly.
Due to the change in the synovial fluid and, for other, more complex reasons, the cartilage in the joint gradually wears away. In some places in fact, the cartilage may eventually disappear altogether. The thinning of the synovial fluid and wearing away of the cartilage lead to the symptoms of osteoarthritis, which include pain, stiffness and swelling.
Osteoarthritis may also occur in younger people, usually (but not always) because these joints have been overloaded. Possible causes of overloading include sports, jobs involving a lof of lifting and carrying, too much body weight and abnormal joint development.
Ostenil® is a solution containing hyaluronic acid. It is injected into the space in the joint that contains synovial fluid and works by restoring the normal balance between the breakdown and production of hyaluronic acid. This effect of Ostenil® means that it can decrease pain and stiffness and improve the other symptoms of osteoarthritis.
The hyaluronic acid in Ostenil® is very pure and is manufactured using a process called fermentation. It contains no animal proteins, which means that it is very unlikely to cause an allergic reaction. Ostenil® has been given to thousands of patients and has not been found to cause any serious side effects. The exact makeup of the hyaluronic acid in Ostenil® has been carefully chosen so that it is as effective as possible in treating osteoarthritis.
If you decide to have treatment with Ostenil®, it will be injected directly into the joint affected by osteoarthritis. This will be done once a week for 3 weeks until you have had 3 injections. The improvement in your symptoms should begin after a few weeks and last for several months. Once the effects of the first course of injections wear off, you can, if you choose, have another. After that, you can continue to have new courses of injections whenever necessary.
