OCD Lesions of the Talus

OCD lesions of the talus occur when the protective cartilage at the top of the ankle bone (talus) is damaged. Pain from OCD lesions range from mild to severe and can lead to osteoarthritis and limited joint function when not treated.

Causes

Researchers are still unsure what causes OCD lesions to occur. It often happens after a sprained ankle or from repetitive use that crushes and tears cartilage between bones. The talus can also fracture, limiting blood supply to the bone.

Symptoms

Symptoms vary based on the severity of cartilage damage. Pain, swelling, and tenderness are all common, and the ankle may feel weak. Range of motion is also impacted and a popping sensation may be noticeable with movement.

Diagnosis

Physicians will review symptoms and medical history to diagnose OCD lesions of the talus. A physical exam will take place to verify symptoms such as swelling and tenderness. Imaging tests may also be used to identify the location of the OCD lesion.

Treatment

In most cases, OCD lesions of the talus can be treated with rest, pain medications, bracing or casts, and physical therapy. However, minimally invasive surgery may be required to repair the damaged cartilage if conservative treatments are not effective.
