What are the first signs of meniscus tear?

Symptoms often follow a twist, pivot, deep squat, or sports movement, although a meniscus can also become more vulnerable gradually. Pain is commonly felt on the inner or outer side of the knee. Swelling may appear soon after injury or build later. A knee may give way, click, or feel as though something is caught inside it. These features overlap with ligament, cartilage, and kneecap problems, so they cannot confirm the diagnosis alone.

Reduce twisting, running, deep squats, and movements that provoke catching. Use comfortable rest and gentle motion rather than forcing the knee through pain. Note the injury mechanism, swelling, locking, and whether you can bear weight. A clinician may assess joint-line tenderness, stability, and range of motion, then decide whether imaging is needed. Physiotherapy can support strength and control; selected tears may be considered for meniscus repair or knee arthroscopy.

Seek prompt care if the knee is truly locked and cannot straighten, gives way repeatedly, or becomes markedly swollen after injury. Urgent assessment is needed when you cannot bear weight, the knee looks deformed, or severe pain follows major trauma. Persistent clicking with pain, swelling, or loss of motion also deserves an examination.

Ask whether the symptoms localise to the meniscus, whether a scan would change treatment, and which movements to avoid. Discuss physiotherapy, expected recovery, and when repair or arthroscopy would be considered.
