Osteochondritis dissecans, or OCD, is a rare condition caused when a fragment of bone becomes loose in the joint. The condition’s cause differs depending on your age. For adults, OCD forms after the physis or epiphyseal plate has closed, while for young people, it can occur while still growing.

It is not only limited to the knee but can occur in the elbow, ankle, wrist, hand, shoulder or hip. The exact causes are unknown but it is believed there a number of contributing factors responsible, including:

  • Biochemical
  • Genetic predisposition
  • Repetitive trauma
  • Ischaemia
  • Ligamentous laxity
  • Abnormal ossification

Certain sports, such as rugby, football, boxing or running may also be a cause and can make the condition worsen significantly quicker.

The four stages of OCD

There are four stages to the condition, with each stage increasing the severity:

  • Stage 1 - the articular cartilage will thicken.
  • Stage 2 - the articular cartilage is interrupted.
  • Stage 3 - the underlying subchondral bone undergoes changes
  • Stage 4 - bone has become loose in the joint

Symptoms of OCD

OCD is likely to display symptoms during a person’s teenage years with knee pain being the first signal. Other symptoms include swelling, a sensation in the knee, joint locking and a feeling that the joint is going to give way.

If you suspect OCD, it is important that you make an appointment with your GP as soon as possible so they can make a diagnosis and prescribe suitable treatment. Your doctor can diagnose your condition in a number of ways, including:

  • An X-ray
  • A magnetic resonance imaging (MRI) scan
  • A computed tomography (CT) scan
  • Scintigraphy

Treatment

The earlier the condition is diagnosed, the better outlook for recovery. If the condition is caught while you are young, there is a greater chance of quicker healing. Otherwise, aggressive treatments may need to be used.

Non-drug treatments include stopping all activities, limiting walking and attending physiotherapy regularly to strengthen the muscles around the knee. Immobilising or protecting the knee joint with a brace are also viable options.

If the pain is unbearable, painkillers and other NSAIDS can be used to reduce it but will not alleviate the disease.


Surgical solutions are only taken as a last resort, for severe cases or when other treatments have not worked. Keyhole surgery or arthroscopy is usually the method used for one of the following options:

  • Arthroscopic subchondral drilling
  • Arthroscopic excision, drilling and curettage
  • Open removal of all loose bones
  • Bone grafting
  • Autologous chondrocyte transplantation

Depending on the type of surgery you have undergone, recovery can take between 6-10 weeks. Patients should ensure they rest to allow the injury to heal, follow the instructions of any doctors or physiotherapists and make an appointment should symptoms persist.

Stages of Recovery from Knee Replacement


The knee is a vital joint that enables movement and stability in the leg. If the health of the knee is affected and other treatments have not given relief, the entire joint may be replaced with surgery. It can take months to recover after this type of surgery, and it may even be a year before the knee has full strength and endurance, so it is not an operation to undergo lightly. However for those whose knees are worn, damaged or causing great pain, a knee replacement can give great relief.

​Remarkable surgical techniques involved in a hip replacement?


Hip osteoarthritis is a condition that affects around 11% of the UK population over the age of 45. It is caused by a loss of cartilage around the hip joint, and this results in pain, stiffness and reduced mobility. While age is the biggest factor in developing hip osteoarthritis, other factors such as being overweight or not taking enough exercise can also play a role. After someone has been diagnosed with hip osteoarthritis, hip replacement surgery might be prescribed. This procedure may sound drastic but is actually relatively straightforward and not as invasive as it sounds.

Knee arthroscopy versus tibial osteotomy versus knee replacement surgery


All these options have different benefits and are suitable for different requirements and scenarios. A treatment that has been deemed suitable for your friend may be completely inappropriate for you as all treatment options are dependent entirely upon your unique medical circumstances (even your social circumstances).

The OA knee


OA is the shortening for osteoarthritis, a condition whereby a sufferer develops problems with movement in the knee joint, including pain and stiffness. Read on to discover more about the symptoms of this condition, the probable causes, possible complications, treatments and ways to live with the condition comfortably.

#

Why is it important to focus on multiple treatment options simultaneously?


Because there is no stand-out, totally effective single treatment for osteoarthritis, people with the condition often find it best to put together a personal portfolio of treatments that will work together to help relieve pain and improve mobility. The combination that works for one person may not work for another, so it’s important to understand what’s available, how effective it is and whether it will help your personal condition.

What are the top 10 most common causes of osteoarthritis?


Osteoarthritis, or OA, is a degenerative joint condition that affects over 8 million people in the UK. This disease is the most common form of arthritis, and is particularly prevalent amongst the older population. Affecting the cartilage in a joint, osteoarthritis can result in pain, stiffness and reduced mobility.
