Osteochondral dissecans is a joint condition that happens when the bone underlying the joint surface cartilage doesn’t have enough blood supply. This lack of blood flow causes the section of bone to die. This can sometimes cause pain and in some cases can even break loose, and cause pain and locking of the joint. An osteochondral fracture can cause similar symptoms, but is an acute injury from trauma.
Osteochondritis dissecans can affect any joint but is most common in the knees. The cause of this joint condition is unknown. For children and teens that are still growing, the injury might heal itself. For older teens, adults and patients with detached bone fragments, surgery might be necessary to help you regain full joint mobility.
Symptoms, Diagnosis and Outlook
Patients with osteochondral dissecans can experience the following symptoms:
Our team of orthopaedic specialists at Penn State Health will evaluate your injured joint for areas of pain and swelling. In some cases, our experts might be able to feel a joint fragment within the joint. To confirm your diagnosis, your physician will order imaging like X-ray, computerized tomography (CT) or magnetic resonance imaging (MRI) to get a comprehensive look inside of your joint.
If you are diagnosed with osteochondritis dissecans, initial treatment might include using crutches, resting the joint and utilizing physical therapy. If you have a loose bone fragment, surgical recommendation is more likely. If the bone fragment is not loose and you are experiencing any relief with conservative treatment options, surgery to address the lesion may also be an option.
