The Knee: How Much Do You Know About Knee Pain?

If a person experiences a grating, grinding sound during a deep knee bend, it is likely that they have chondromalacia. Chondromalacia is a condition that occurs when the cartilage on the underside of the kneecap becomes damaged or worn down. This can cause friction and grinding sensations when the knee is bent. Therefore, the statement "If a deep knee bend causes a grating, grinding sound, it is very likely that the person has chondromalacia" is true.

Swelling in the knee is commonly associated with ligament or joint injuries. Ligament injuries, such as a sprain or tear, can cause inflammation and swelling in the knee. Similarly, a joint injury, such as a dislocation or meniscus tear, can also lead to swelling. Therefore, it is likely that if there is swelling in the knee, it is due to a ligament or joint injury.

Referred pain is the phenomenon where pain is felt in a different location than the actual source of the pain. However, in the case of the knee, there is no referred pain. This means that if there is pain in the knee, it is most likely due to an injury or issue specifically in the knee itself, rather than being caused by a problem elsewhere in the body. Therefore, the statement "where it hurts is where it is injured" is true in the context of knee pain.

When the knee gives way, it usually means that there is an injury to the meniscus. This is because the meniscus is a structure in the knee that helps with stability and shock absorption. When it is injured, it can cause the knee to feel unstable and give way. Therefore, the statement "True" is correct.

A patella tendon injury typically causes pain and discomfort when going up or climbing stairs, rather than going down. This is because the patella tendon is responsible for extending the knee, and the action of going up stairs requires more effort and engagement of the patella tendon compared to going down stairs. Therefore, the statement is false.

When the knee locks in flexion, it does not necessarily mean that there is a loose piece of bone or cartilage in the joint. Other possible causes of a locked knee include a meniscus tear, a ligament injury, or a muscle spasm. Therefore, the statement is false.
