Osteochondral Lesion Treatment at Foot Foundation
An osteochondral lesion is an injury to the cartilage and underlying bone, often after sprains or trauma.
At Foot Foundation, we provide accurate diagnosis, orthotics, and structured rehabilitation, with referral to orthopaedics where required.
What are Osteochondral Lesions of the Ankle?
Osteochondral lesions of the ankle (also known as osteochondritis dissecans or osteochondral defects) are injuries to the cartilage and underlying bone of the talus (ankle bone). They often occur following an ankle sprain or trauma, when a piece of cartilage and subchondral bone becomes damaged, loosened, or in some cases displaced.
This condition can cause chronic ankle pain, swelling, catching, or locking, particularly during weight-bearing. If untreated, it may progress to early ankle arthritis.
Causes & Risk Factors
Trauma – most commonly ankle sprains or fractures
Repetitive microtrauma – long-term overloading in athletes
Poor ankle stability – chronic ankle instability increases risk
Biomechanical factors – abnormal joint alignment causing focal stress
Reduced blood supply to subchondral bone (rare)
Genetic predisposition – some patients may have inherent cartilage weakness
Treatment at Foot Foundation
Activity modification – reduce high-impact loading while healing occurs
Custom orthotics – redistribute forces across the ankle joint
Footwear modification – cushioned shoes, possible rocker soles
Strengthening and proprioception programs – improve stability and reduce recurrence
Shockwave therapy – to stimulate bone and cartilage healing in certain cases
Referral to orthopaedics – if the lesion is large, unstable, or not responding to conservative care (arthroscopy, microfracture, grafting, or fixation procedures)
Symptoms
Deep ankle pain, often worse with weight-bearing
Swelling and stiffness after activity
Catching, locking, or “giving way” of the ankle joint
Tenderness over the talus with palpation
Loss of confidence in the ankle during activity
Diagnosis
At Foot Foundation, diagnosis is made through:
Clinical history (trauma or recurrent ankle sprains)
Physical examination – joint palpation, range of motion, stability testing
Imaging:
X-ray – may show bone fragments or defect
MRI – gold standard for assessing cartilage integrity, lesion size, and stability
CT scan – in complex or pre-surgical planning cases

Frequently Asked Questions
What is an Osteochondral Lesion?
An Osteochondral Lesion is an injury to the cartilage and underlying bone within the ankle joint, most commonly affecting the talus. It can cause pain, swelling, stiffness, and mechanical symptoms such as catching or locking.
How do Osteochondral Lesions occur?
Most Osteochondral Lesions occur after an ankle sprain or other trauma, where twisting or impact damages the cartilage and bone. Some lesions can also develop gradually from repeated microtrauma or long-term joint overload.
What are the symptoms of an Osteochondral Lesion?
Common symptoms include deep ankle pain, swelling after activity, stiffness, catching, locking, and a sense of instability or lack of confidence in the joint.
How are Osteochondral Lesions diagnosed?
Diagnosis is made through clinical assessment and imaging. MRI is often the most useful scan because it shows cartilage integrity, lesion size, depth, and stability. X-rays or CT scans may also be used depending on the case.
Can Osteochondral Lesions heal on their own?
Some smaller or more stable lesions may improve or settle with conservative treatment. Larger, unstable, or persistent lesions are less likely to resolve fully without further intervention.
What is the best treatment for an Osteochondral Lesion?
Treatment depends on the size and stability of the lesion. Conservative management may include activity modification, orthotics, footwear changes, and rehabilitation. Larger or unstable lesions may need orthopaedic referral for procedures such as arthroscopy, microfracture, grafting, or fixation.
What happens if an Osteochondral Lesion is left untreated?
If not managed properly, the lesion may continue to cause pain, swelling, and joint dysfunction, and in some cases may contribute to long-term cartilage damage and early ankle arthritis.
Can orthotics help Osteochondral Lesions?
Yes. Orthotics can help reduce focal loading through the ankle joint, improve biomechanics, and offload the injured cartilage and bone to help improve comfort and joint protection.
When should I see a podiatrist for ankle pain?
If you have persistent ankle pain, swelling, catching, locking, or instability after a sprain or injury, it is best to seek specialist assessment early so the joint can be properly evaluated.

Our approach to Osteochondral Lesions
At Foot Foundation, our approach to Osteochondral Lesions begins with a thorough assessment to identify the source of your ankle pain, determine whether cartilage and bone injury may be involved, and understand how your symptoms are affecting joint function and stability.
Once the diagnosis is confirmed, we create a personalised treatment plan focused on reducing pain, improving joint mechanics, protecting the injured area, and supporting long-term ankle function. Depending on your presentation, treatment may include activity modification, custom orthotics, footwear modification, strengthening and proprioception programmes, and rehabilitation to improve stability and reduce recurrence. In more significant or resistant cases, we may also recommend imaging review and referral to orthopaedics for further management.
Our goal is not only to reduce current pain, but also to protect the ankle joint, restore confidence in movement, and reduce the risk of long-term complications such as ongoing instability or early arthritis.
