What Causes an Osteochondral Lesion of the Talus?

An ankle sprain or twist can compress the cartilage and bone on the talar joint surface. Repeated sprains, ankle instability and impact may prevent the injury from healing. The lesion may not be visible on the first X-ray.

Symptoms

• Deep ankle pain that increases with weight bearing
• Joint swelling at the end of the day or after a long walk
• Catching or clicking during ankle movement
• Uncertainty on stairs or uneven ground

Frequently Asked Questions

How is a talar osteochondral lesion treated?

Treatment depends on lesion size, displacement and the patient's age. Reducing load, protecting the ankle and rehabilitation may be tried first. If symptoms continue, MRI or CT findings guide options such as arthroscopic cleaning, bone stimulation or cartilage repair.
