Osteochondritis Dissecans Knee Symptoms

Pain may be felt around the involved part of the knee and can become more noticeable during running, jumping, stairs, or other loading. Swelling may follow activity. Some people notice stiffness or reduced knee movement, especially after resting.

If a cartilage-and-bone fragment becomes loose or shifts, the knee may catch, click, or lock. Knee locking means the joint cannot move normally for a moment or remains stuck; it deserves assessment rather than repeated forceful movement. These symptoms overlap with other knee conditions, so symptoms alone cannot confirm osteochondritis dissecans.

Record when pain, swelling, catching, or locking occurs and which activities trigger it. Reduce impact and deep bending that clearly worsen symptoms while arranging clinical advice. An examination may be paired with imaging to assess the lesion, the cartilage surface, and whether a fragment is stable.

A stable lesion may be managed with activity modification and guided physiotherapy to preserve motion and build supporting strength. Persistent symptoms or an unstable fragment can lead to a discussion about cartilage repair surgery. Treatment should match the examination and imaging findings.

Arrange an orthopaedic review for ongoing knee pain, repeated swelling, or reduced movement. Seek prompt care if the knee locks and will not release, you cannot bear weight, swelling appears suddenly after an injury, or the joint looks deformed. Urgent assessment helps distinguish a mechanical blockage from another injury.

Ask whether the symptoms suggest a stable or unstable lesion, which activities are safe, what imaging is needed, how physiotherapy should be structured, and what findings would make cartilage repair surgery worth considering.
