Knee cartilage injury
A focal cartilage defect is different from widespread osteoarthritis. Symptoms depend on the location and extent of damage, underlying bone and how the knee carries load. The grade in an MRI report is only one part of the assessment.
Assessment
What the assessment considers
Relevant questions include defect size, alignment, meniscus function, ligament stability and previous surgery. MRI and appropriate radiographs help distinguish a localized lesion from more diffuse joint disease. Swelling and exercise tolerance are considered alongside imaging.
Next steps
Treatment and next steps
Activity adjustment and strength training are often part of the plan. Selected focal defects may be suitable for cartilage procedures, but surrounding mechanical problems also need attention. Injections may help symptoms in selected cases; they should not be presented as guaranteed regrowth of normal cartilage.
Your consultation
Prepare for the consultation
Bring original images and reports, previous operation notes, a medication list and a short timeline of symptoms and treatment. Write down the activities you want to regain and your most important question. Initial inquiries should not include confidential medical attachments; agree a suitable transfer route with the practice first.
Travel and continuity of care
Coming from abroad?
Confirm the consultation language, any interpreting needs, fees and the appropriate appointment before booking travel. This website’s language does not guarantee a consultation in that language. Follow-up and communication with your local clinicians should be planned in advance.

Second opinion
A second opinion examines whether an existing recommendation fits your symptoms, function and goals. It may confirm the proposed treatment or identify an alternative; it is not a promise to avoid surgery.
Rehabilitation
Plan recovery around function, progressive loading and your activity goals.

Common questions
Answers to common questions.
Does the cartilage-damage grade on MRI determine treatment?
No. The grade describes damage depth but does not replace clinical assessment. Defect size and location, underlying bone, meniscus, ligament function and leg alignment also matter. The findings must fit the pain, swelling, movement and loading pattern; an MRI finding alone is not the treatment decision.
Can knee cartilage damage be treated without surgery?
Yes. Many stable defects and early to moderate arthritic changes can initially be managed with exercise and load adjustment. Surgery becomes more relevant for a mechanically troublesome, full-thickness or osteochondral defect, or when well-conducted nonsurgical treatment is insufficient. The choice remains individual.
Can I continue sport with knee cartilage damage?
Often, but activity needs to match the sport, pain, swelling, defect location and next-day response. Loading is usually adjusted and increased gradually. True locking or increasing joint irritation needs reassessment rather than simply continuing the same training.
Do I need to repeat my scans?
Not automatically. Bring the original images and reports first. Further imaging is considered if the existing study does not answer the clinical question or if your condition has changed.
Can this be assessed without travelling?
Some questions can be reviewed from records, but physical examination may be essential. Ask the practice to confirm suitability, scope and a secure document-transfer route before sending records or booking travel.
How are treatment costs and follow-up agreed?
Request an individual estimate and clarify reimbursement with your insurer. Ask which examinations, written reports and follow-up visits are included. International patients should also plan rehabilitation and medical contact after returning home.
