Knee Condition

Osteochondral Lesions

Symptoms, Diagnosis & Treatment Options

An osteochondral lesion involves both the cartilage surface and the bone just beneath it. Because both layers are affected, these injuries need careful assessment and a considered plan.

An osteochondral lesion is an injury to a small area of cartilage together with the bone immediately beneath it. In adolescents this often takes the form of osteochondritis dissecans, where a segment of bone loses its blood supply and the cartilage above it can loosen.

1. Anatomy & Overview

An osteochondral lesion is an injury to a small area of cartilage together with the bone immediately beneath it.

Clinical examination

2. Signs & Symptoms

Aching, activity-related pain — often poorly localised at first.

Diagnostic imaging

3. Diagnosis & Imaging

X-rays can show the bony part of the lesion, but an MRI is essential — it reveals whether the fragment is stable or loosening, the health of the cartilage and bone, and the presence of any loose bodies.

Treatment

4. Treatment Options

Protected healing: Stable lesions in growing patients can heal with a period of reduced loading and monitoring.

Rehabilitation

5. Recovery & Rehabilitation

Recovery is staged and protective, allowing the bone and cartilage to heal before impact is reintroduced — typically over several months.

Frequently Asked Questions

What are the symptoms of Osteochondral Lesions?

Aching, activity-related pain — often poorly localised at first. Swelling — after activity. Catching, locking or clicking — if a fragment has loosened. A sense of the knee “giving way” — or not feeling reliable.

What causes Osteochondral Lesions?

Repetitive impact and overload in young athletes. A single significant injury to the joint surface. Interrupted blood supply to a segment of bone. Growth-related vulnerability in adolescence.

How is Osteochondral Lesions diagnosed?

How is Osteochondral Lesions treated?

Protected healing: Stable lesions in growing patients can heal with a period of reduced loading and monitoring. Fixation: A loosening but viable fragment can be pinned or screwed back into place to heal. Resurfacing: A detached fragment is removed and the defect restored with cartilage transfer or regeneration techniques.

What does recovery involve?

Recovery is staged and protective, allowing the bone and cartilage to heal before impact is reintroduced — typically over several months. Outcomes are good, especially for stable lesions treated early, with the goal of preserving the joint surface for the long term.
