Why does a meniscus tear cause knee pain?

A meniscus tear may irritate sensitive tissue around the joint and reduce the cushion between the thighbone and shinbone. Loading the knee can press on the injured area, while turning or crouching may stretch it. Inflammation can make the joint more tender and may limit comfortable movement. Pain can be felt along the inner or outer joint line, depending on which part is affected. Knee pain has many possible causes, so its location, onset, and associated symptoms matter.

Temporarily reduce twisting, kneeling, deep bending, and impact if these actions increase pain. Keep ordinary movement gentle and within a comfortable range rather than holding the knee completely still. A wrapped cold pack and leg support may help with irritation. A clinician or physiotherapist can recommend exercises that maintain strength without repeatedly loading the sore area.

Arrange an assessment for pain that persists, follows a twist or fall, limits walking, or comes with swelling, clicking, locking, or giving way. Seek urgent help for severe pain after a substantial injury, a deformed knee, inability to bear weight, or a hot swollen joint with fever.

Ask where the pain seems to originate; which activities are safe; whether physiotherapy is suitable; whether an examination or scan is needed; and how to tell expected soreness from a problem needing review.
