What does knee locking feel like with a meniscus tear?

The meniscus is a curved pad that helps distribute load between the bones of the knee. A torn portion can become irritated or interfere with the joint during a turn, squat, or change from sitting to standing. You might feel a sharp catch, a click followed by a blocked movement, or a knee that releases after repositioning. Swelling and tenderness along the joint line can accompany the episodes. Locking is a symptom, not proof of a meniscus tear, and examination is needed to sort out the cause.

When the knee catches, stop rather than pushing through resistance. Rest with the leg supported and use gentle movement only within a comfortable range. Avoid pivoting, deep squats, kneeling, and sports that make the knee lock. A wrapped cold pack can ease swelling for a short time. Keep track of triggers, whether the knee fully releases, and whether walking becomes difficult.

Arrange prompt assessment if the knee stays locked, cannot bear weight, or swells suddenly after an injury. Seek urgent care for obvious deformity, severe pain, or a foot that becomes numb, pale, or cold. Repeated locking, persistent swelling, or loss of normal movement also deserves a clinical review even when symptoms settle between episodes.

Ask whether the locking pattern suggests a meniscus injury, whether physiotherapy is suitable, and what activity level is safe. Share how the injury happened, where you feel pain, whether there is clicking, and how long each blocked episode lasts.
