Does your knee hurt when you bend it? here are 4 conditions that could be the trigger

The knee is one part of the body that plays an important role in helping support the body when you stand and walk. Unfortunately, there are many conditions that can cause your knee to suddenly feel painful or sore when bent. So, what are the causes of knee pain when bent? Find out the answer here.

Various causes of knee pain when bent

Here are some of the most common conditions that can cause knee pain when bent:

1. Sprains

Experiencing sprains or sprains in the ligaments that help stabilize the knee can also be the cause of this condition. Yes, if one of the ligaments in the knee is torn or too tight, then you are more likely to experience knee pain when bent or even simply straightened.

The pain that appears varies depending on how badly damaged the ligament is.

2.Pain in the kneecap (patellofemoral pain syndrome)

Patellofemoral pain syndrome is a condition when you feel pain in the patella, which is the small bone in the knee. Pain that appears is usually felt around the knee or the back of the knee.

The pain that appears can vary depending on its severity. However, it will usually be more painful if your knee is subjected to pressure for a long time.

For example, going up and down stairs, running, or standing for too long. Not only that, but bending your knees for a long time while sitting watching a movie or being on a train can also cause pain.

3. Bursitis

Bursitis is an inflammation of the bursa, which is a sac filled with lubricating fluid that is between the bone and soft tissue. Usually bursitis appears in the joints that are frequently moved, for example the shoulders, elbows, hips, knees and feet. This condition can cause the knee to become stiff and painful when bent.

You are more likely to develop this condition if you bend your knees and kneel for too long. Not only that, experiencing a hard impact due to an injury or accident in the knee can also cause this condition.

4. Tear the meniscus

The meniscus is a layer of cartilage in the knee that functions to protect and stabilize the knee joint. So, when you move the knee joint, it is this layer of cartilage that keeps the thighbone and shin from rubbing against each other.

A meniscus tear is usually caused when you involuntarily make a circular motion in the knee joint when the foot is flat and the knee joint is bent. Injury to the knee from sports or accidents can also cause a tear in the meniscus.

A torn meniscus can cause the outside or inside of your knee to feel painful, stiff, and difficult to move. If not treated properly, pain can recur at any time.

5. Other causes

In certain cases, this condition can also be caused by more serious medical conditions such as osteoarthritis (calcification of the joints) and bone cancer that affects the knee.

Given that there are many possible causes of knee pain when bent, it's a good idea to consult a doctor immediately to determine the right diagnosis.
