Frequently asked questions
Can a meniscus tear heal without surgery?
Small tears in the outer, well-supplied part of the meniscus can heal with rest and physiotherapy. Tears in the inner part have poor blood supply and may need surgery.
Is it safe to keep walking with a meniscus tear?
Gentle walking is usually fine, but avoid deep squats, twisting and heavy loading until you have been assessed, as these can worsen the tear.
