Osteochondritis Dissecans (OCD)

What is an osteochondritis dissecans (OCD) lesion?

An osteochondritis dissecans (OCD) lesion is a condition where a small piece of bone and the overlying cartilage in the knee joint becomes damaged due to poor blood supply. This can cause the fragment to loosen or break off, leading to pain, swelling, and sometimes locking or catching in the knee. OCD most commonly affects active children and young adults, especially those involved in sports. Early diagnosis is key to preventing long-term joint damage.

The exact cause of osteochondritis dissecans (OCD) isn’t always clear, but it’s thought to result from repetitive stress or microtrauma to the knee that disrupts blood flow to a section of bone. Over time, this weakens the bone and its overlying cartilage. Genetic factors, growth patterns, and joint mechanics may also contribute. OCD lesions often develops in young athletes during growth spurts when bones and cartilage are still maturing.

Diagnosis begins with a physical exam and a discussion of your symptoms, such as knee pain, swelling, or catching during activity. X-rays can often reveal the lesion, especially if the bone fragment is starting to separate. MRI is typically used to assess the size and stability of the lesion, which helps guide treatment decisions.

Treatment depends on age, activity level, and the stability of the lesion. In younger patients, non-surgical options like activity modification, bracing, and physical therapy can help the lesion heal naturally. If the fragment is unstable or has detached, surgery may be recommended to secure, remove, or stimulate new cartilage and bone growth. Early treatment can often prevent long-term knee damage and help patients return to sports. Sachin Allahabadi MD takes into account multiple factors to help guide treatment for OCD lesions.
