Ankle Cartilage Damage: When Is Surgery the Right Choice?

You expected your ankle to feel better weeks after the sprain. Instead, there is a deep ache with every step, swelling that comes and goes, and uneven ground makes you slow down. When pain lingers after what seemed like a simple ankle injury, the problem may be more than a stretched ligament. 

Cartilage injuries are a common reason for ongoing ankle pain after a sprain. In fact, research finds that up to 70% of acute ankle sprains are associated with cartilage injuries of the talus, which is the bone that forms the lower part of the ankle joint. Treating these injuries early makes a huge difference in preserving joint function and reducing the risk of arthritis later in life.

Continue reading to learn how ankle cartilage damage is diagnosed, when surgery is recommended, and where to find the best ankle surgeon in West LA.

Why Does My Ankle Still Hurt After an Ankle Sprain? 

Persistent ankle pain after a sprain can mean the injury involves more than stretched ligaments. An osteochondral lesion of the talus (OLT) develops when the smooth cartilage covering the talus, along with the bone beneath it, is damaged during an ankle injury. While ligaments often heal over several weeks, cartilage has a limited blood supply, making it much slower to repair. If the damaged cartilage becomes loose or unstable, it can continue to irritate the joint every time you walk, pivot, or climb stairs.

With this injury, patients often describe symptoms differently than a typical ankle sprain. Instead of pain only along the outside of the ankle, they notice a deep ache inside the joint that never completely goes away. Swelling may appear after activity rather than immediately after the injury. Some people feel clicking, catching, or even brief episodes where the ankle seems to lock. These symptoms suggest the joint surface itself may be involved.

One misconception is that normal X-rays or the ability to walk mean the injury has healed. In reality, many cartilage injuries are not visible on standard X-rays, especially during the early stages. Experienced foot and ankle specialists in West LA become suspicious when pain lasts well beyond the expected recovery from a sprain or when patients cannot return to their usual activities despite completing physical therapy. With this in mind, if your ankle continues to hurt weeks or months after a sprain, cartilage damage should be considered as a possible cause rather than assuming the injury simply needs more time.

How Do Foot and Ankle Specialists in West LA Diagnose Ankle Cartilage Injuries?

Diagnosing ankle cartilage damage requires combining your symptoms, a detailed physical examination, and advanced imaging. While ankle specialists may suspect an osteochondral lesion during the examination, MRI is usually the best test for confirming cartilage injury because it shows both cartilage and the underlying bone. 

Can Ankle Cartilage Heal Without Surgery? 

Some ankle cartilage injuries improve without surgery, particularly when the lesion is small, stable, and symptoms are mild. Treatment often begins with activity modification, physical therapy, anti-inflammatory medication, bracing, or a temporary period of protected weight-bearing. 

Surgery is a more effective treatment when pain persists despite conservative treatment, when imaging shows unstable cartilage or loose fragments, or when the damaged area is large enough that it is unlikely to heal on its own. Younger, active patients often benefit from addressing significant cartilage injuries before secondary arthritis develops. Waiting until severe arthritis is present may limit the number of joint-preserving options available.

What Happens During Surgery for an Osteochondral Lesion?

Smaller lesions are often treated arthroscopically through tiny incisions. During this minimally invasive procedure, the best ankle surgeon in West LA removes unstable cartilage and may perform microfracture, which creates small openings in the bone to stimulate the growth of new repair tissue.

Larger or more complex lesions may require cartilage restoration procedures. These can include osteochondral grafting, which transfers healthy cartilage and bone into the damaged area, or advanced cartilage transplantation techniques that replace larger defects. The decision also takes into account your age, activity level, previous surgeries, and overall ankle health.

What Is Recovery Like After Ankle Cartilage Surgery?

Recovery after ankle surgery takes time because cartilage heals much more slowly than skin or muscle. Most patients spend several weeks protecting the ankle with limited or no weight-bearing, followed by progressive physical therapy that restores strength, balance, flexibility, and normal walking mechanics. Returning to sports or high-impact activities often takes several months, depending on the procedure performed.

One of the biggest milestones specialists look for is restored ankle stability, normal movement patterns, and the ability to tolerate increasing activity without swelling afterward. Patients usually start to feel better before the cartilage has fully matured, which is why following rehabilitation instructions remains important even when symptoms improve. Protecting the healing cartilage during rehabilitation gives the joint the best chance for long-term success.

Finding the Best Ankle Surgeon in West LA for Recurring Ankle Sprains

Cartilage damage in the ankle does not always require surgery, but persistent pain, catching, or swelling after an injury should never be dismissed as a sprain that simply needs more time to heal.
