What does it mean to have a locked knee joint?

A locked knee joint occurs when the knee becomes stiff and can’t move fully, usually getting stuck in a certain position. This can happen if there’s a mechanical issue within the joint itself, often due to injury or underlying conditions.

What are the common causes of knee locking?

Several factors can lead to knee locking. Here are some of the most common:

1. Meniscus Tear: The meniscus is a cartilage cushion in the knee. If it tears, it can create a loose flap that catches in the joint, causing a lock.
2. Loose Bodies: Small fragments of bone or cartilage can break off and float in the joint space, interfering with movement.
3. Ligament Injuries: Injuries to ligaments may also cause instability, leading to locking sensations.
4. Arthritis: Conditions like osteoarthritis can cause bone spurs that limit movement.
