Ankle Catching or Deep Pain After a Sprain: Could Cartilage Be Injured?

Your ankle sprain seemed to be settling down, but something still does not feel right. The joint aches deep inside, swells after activity, or occasionally catches when you move. Returning to your usual routine has become a series of trial-and-error decisions.

Persistent symptoms deserve reassessment. One possible explanation is an osteochondral lesion of the talus: an injury involving the ankle bone's joint surface and the cartilage above it. It is one of several potential causes of ongoing ankle pain, and symptoms alone cannot confirm it.

What does “osteochondral” mean?

The word refers to bone and cartilage. The talus forms the lower part of the ankle joint, and its cartilage helps the joint move smoothly. An injury to this surface may follow a sprain or other trauma. Symptoms can include a deep ache, recurrent swelling, catching, or a feeling that the ankle gives way. Some people do not remember a specific injury.

When to return for another evaluation

Book a reassessment when recovery stalls or ordinary activity repeatedly brings back symptoms. Tell the clinician if the joint actually locks, if movement becomes restricted, or if swelling returns after you increase activity. A painless click is not the same as a joint that catches and will not move normally.

Do not force a locked ankle to bend. Seek prompt care for a newly locked joint, severe pain, or inability to bear weight. A cold or numb foot, an open injury, or obvious deformity needs emergency assessment.

Why another test may be useful

Your clinician will review the injury and examine the joint. X-rays are useful, but a cartilage injury may require MRI or CT to better understand it. The decision depends on the examination and the information already available. Additional imaging is not automatically necessary for every ankle sprain.

If you have already completed treatment elsewhere, bring the dates, imaging reports, and details of any rehabilitation program. Describe what improved and what did not. “It swells every time I try a longer walk” is a practical observation that can help guide the discussion.

What are the treatment options?

Selected lesions can be treated with protection, restricted weightbearing, and rehabilitation. Surgery may be considered for certain injury patterns or symptoms that persist despite appropriate care. Not every lesion progresses, and an imaging finding without symptoms does not always need intervention.

Some procedures can be performed through arthroscopy, using a small camera and instruments. Others need a different approach depending on the lesion's size and location. Restore's ankle arthroscopy information explains this treatment area. Having persistent pain does not, by itself, establish that surgery is the next step.

Make your next visit more productive

Write down the activities that matter most: walking at work, climbing stairs, exercising, or playing with your children. Ask which activities are appropriate while the diagnosis is being clarified. If you have a race or travel date in mind, share it without treating it as a deadline the ankle must meet.

Useful questions include: What is the likely source of pain? Is the joint stable? Would another image change the treatment plan? What does progress look like? When should we revisit the plan? Ask for clear instructions about braces or mobility aids if they are recommended.

Common questions

Does a normal first X-ray rule this out?

Not necessarily. Persistent symptoms may justify further assessment even after an earlier reassuring X-ray.

Can I exercise through the catching?

Do not repeatedly provoke painful catching. Discuss suitable activity with your clinician instead of testing the joint at higher intensity.

Is this the same as a ligament sprain?

No. Ligaments and joint cartilage are different structures, although one injury can affect more than one area.
