Osgood-Schlatter disease, sometimes referred to as Osgood's or OSD, is a condition that causes the bones, cartilage and tendons at the top of the shinbone or tibia where the patellar tendon is attached to become inflamed. The syndrome is most commonly found amongst active young people aged 8 to 15 years old but has also been known to affect some adults too.

Although it is called a disease, Osgood's is more of an injury that develops through overuse of the quadricep muscle, which, in an adolescent, causes strain on the developing tibia causing the bone to flake. This can result in a hard bony bump as the bone heals, which is why Osgood’s has the nickname ‘knobbly knee’.

Symptoms of Osgood-Schlatter Disease

The most common symptoms of Osgood’s include:

  • Swelling and tenderness in the knee
  • Redness around the knee
  • Tightening of the muscles around the knee
  • Worsening knee pain following exercise

These characteristics along with the presence of a small bony bump in the knee makes examinations by your GP relatively straightforward. Doctors will also check your range of movement and if necessary send you for an X-ray to confirm the condition and check the bone flaking.

Preventing injury

Due to the nature of Osgood’s, there are things you can do to reduce the chances of suffering from the condition. For example, during periods of a growth spurt, stretching exercises can be useful to reduce the tightness of muscles in the legs. Other helpful activities include carrying out proper warm up and cool down sessions before and after exercising as well as keeping physical activity to no more than 90 minutes and allowing plenty of time for rest afterwards.

Treatment

There are many different types of treatment available for Osgood’s with the most vital being resting. If the pain is unbearable, a physiotherapist can help create a stretching programme that reduces discomfort, while nonsteroidal anti-inflammatory drugs (NSAIDS) or using ice can provide immediate relief to pain and swelling.

With symptoms likely to come and go with Osgood’s, it is often advised that when symptoms are at their worst any form of physical activity should be stopped. However, when the pain is mild you can continue to be active but should wear suitable sporting accessories, such as shock-absorbent insoles, gel pads and knee pads.

Adult sufferers may be required to have regular massages or use a knee strap or support to reduce the tension to the knees. While in serious cases of Osgood’s, a plaster cast may need to be worn to manage the pain and surgery may be required to rectify any damage to the bones.

How long will it take to recover?

In young people, Osgood’s lasts until the end of their growth spurt, meaning pain can be suffered for weeks, months or even up to two years. Once over the injury, surgery can deal with any bone flaking that hasn’t healed, however, if the small bony lump has already appeared under the knee, this is permanent but will become painless over time.

​5 most important questions to ask your doctor about OA


We all experience aches and pains from time to time. Normally this isn’t a problem. However, when pains become regular they become a cause of concern. Recurring pain or discomfort in the joints may be indications of the onset of osteoarthritis – a condition which, as we age, gradually damages the surfaces of the joints so the joint doesn’t move as smoothly.

​What are the best sources of vitamin C?


We all require vitamin C to maintain good health, and luckily, it's one of the easier vitamins for us to take in through our diets. Vitamin C is found in a huge variety of fruits and vegetables, meaning even the fussiest eaters should be able to find something to their taste. Vitamin C is beneficial to us in all kinds of ways, including helping to maintain our cartilage and blood vessels. It also helps our bodies create dopamine, ATP, tyrosine and peptide hormones. One of the things vitamin C is perhaps best known for is its antioxidant properties. It actually helps reduce oxidative stress to your body, and is even thought to help lower your risk of cancer. This is a pretty impressive list of benefits for a vitamin often given less attention than many others, in the media and health articles.

​What to expect following knee replacement surgery


There are broadly two different types of knee replacement surgery. These are known as partial (sometimes called unilateral) knee replacement, and total or full knee replacement. You may also hear knee replacement being referred to as arthroplasty. Your surgeon will decide which option is best for you depending upon the state of your knee. Partial knee replacement is less invasive and involves less downtime, so if this is a possibility for you, your surgeon will always prefer to choose this option. However, partial knee replacements run a greater risk of the need for revision surgery, so your surgeon will carefully weigh this risk against the short-term benefits.

Treatments for Osteoarthtitis


It has been estimated that the number of people in the UK with osteoarthritis is around 8.75 million with almost half that figure suffering from knee OA. This means that a third of the population aged 45 and older have sought treatment for their condition.

What are the long term effects of pharmaceuticals in managing osteoarthritis?


​Osteoarthritis is a condition that affects your joints. It is caused by everyday wear and tear rather than any specific immune condition, but it is still painful and can be debilitating. It is caused when the cartilage that covers and protects the ends of your bones, where they join, becomes roughened and thickened. The bone underneath the cartilage also thickens, as do the ligaments, the synovium (the inner layer of the joint capsule) and the capsule itself. Sometimes extra synovial fluid is produced, which causes the joint to swell.

What are the long term effects of having knee replacement surgery?


Knee replacement surgery, also known as arthroplasty, involves replacing a damaged, diseased or worn knee joint with an artificial joint. It is an increasingly common surgery, with the majority of patients aged between 60 and 80. There are an increasing number of younger patients undergoing this surgical procedure, however, meaning that more and more people are dealing with the long-term effects.

​What are the most popular treatment options for hip osteoarthritis?


Hip osteoarthritis is a condition that results in the degeneration of cartilage in the hip joint area. When cartilage is lost, friction increases and leads to pain and stiffness. The condition is fairly common and affects around 11% or the population over the age of 45. There is a range of treatment options available to sufferers. However, every treatment has its strengths and weaknesses, and these should be considered carefully.

​Is surgery for osteoarthritis of the knee becoming less popular?


The pain of osteoarthritis of the knee can be almost unbearable, and as one of the most common forms of joint problems, it affects a huge number of patients every year. Eventually, when the knee joint becomes severely damaged, the only real solution is surgery, but there are plenty of options available to sufferers before reaching that point.
