Osteochondritis Dissecans

What is osteochondritis dissecans?

Osteochondritis dissecans is a joint condition in which a small segment of cartilage, along with the underlying bone (subchondral bone), becomes loose and separates from the surrounding area. This most often occurs in the knee, particularly on the medial femoral condyle, but it can also affect other joints such as the ankle, elbow, or shoulder. Physiotherapy plays a key role in managing symptoms and supporting recovery from this condition.

How does osteochondritis dissecans develop?

The exact reason why osteochondritis dissecans develops is not fully understood. However, it is believed to be associated with reduced blood supply to the affected bone, which weakens the area. In some cases, it may also be triggered by repetitive stress, overuse, or a previous joint injury.

What are the symptoms of osteochondritis dissecans?

The most common symptom of osteochondritis dissecans is a persistent, dull ache in the affected joint. This may be accompanied by swelling, stiffness, and a noticeable reduction in movement. In some cases, small fragments of bone or cartilage may become loose, causing additional symptoms such as:

  • Clicking or locking of the joint
  • Weakness in the surrounding muscles
  • Difficulty with walking or running (gait problems)
  • Reduced balance and stability

What should I do if I suspect osteochondritis dissecans?

If you are experiencing symptoms, it is important to seek a professional medical opinion. A physiotherapist or doctor may recommend investigations such as X-rays or MRI scans to confirm the diagnosis. Depending on the severity, treatment may involve physiotherapy, activity modification, and strengthening exercises. In more advanced or long-standing cases, surgery may be suggested. This is often performed arthroscopically (keyhole surgery) to smooth or stabilize the affected joint surface and help relieve pain.

What shouldn’t I do if I have osteochondritis dissecans?

Avoid ignoring your symptoms or continuing with high-impact activities that place stress on the affected joint. Putting excessive weight or pressure through the injured area can worsen the condition and delay recovery. Rest, proper rehabilitation, and following professional advice are essential for long-term joint health.

Physiotherapy treatment for osteochondritis dissecans

Physiotherapy plays a vital role in recovery from osteochondritis dissecans, whether or not surgery is required. Your physiotherapist will design a tailored programme based on your condition, lifestyle, and rehabilitation goals. The focus is on restoring mobility, reducing pain, and strengthening the joint to prevent further injury.

After surgery, cryotherapy is often recommended to help reduce swelling and discomfort. As your recovery progresses, additional physiotherapy treatments may include:

  • Electrotherapy – to relieve pain and support healing
  • Hydrotherapy – gentle water-based exercises to improve mobility and reduce joint stress
  • Exercise programmes – structured stretching and strengthening routines to restore balance and stability
  • Soft tissue therapy – techniques to release tension and improve circulation around the joint

Could there be long-term effects from osteochondritis dissecans?

If physiotherapy begins early and rehabilitation is carefully followed, long-term effects are usually minimal. A gradual, well-structured recovery programme helps restore function, reduces the risk of re-injury, and supports long-term joint health. However, delayed treatment or neglecting symptoms can increase the chance of ongoing pain, stiffness, or reduced mobility.
