What Is the Cause of Aching Knees? Common Reasons Explained in Simple Words

What Is the Cause of Aching Knees?

Aching knees are a very common problem. People of all ages can feel knee pain, from young adults to older people. Sometimes the pain is mild and goes away on its own, but sometimes it can be strong and last for a long time. To understand how to reduce knee pain, it is important to know what causes aching knees.

Below are the most common causes of knee pain, explained in easy words.

1. Aging and Wear and Tear

As we grow older, our joints slowly wear out. The knee joint carries a lot of body weight, so it is more likely to get damaged over time. The cartilage, which acts like a cushion between bones, becomes thin. This can cause pain, stiffness, and swelling in the knees, especially while walking or climbing stairs.

2. Arthritis

Arthritis is one of the main reasons for aching knees.

• Osteoarthritis: This happens when the cartilage in the knee breaks down. It is common in older adults.

• Rheumatoid arthritis: This is an autoimmune disease where the body attacks its own joints, causing pain and swelling.

• Gout: This occurs when uric acid builds up in the joint, causing sudden and severe knee pain. Looking Treatment about Arthritis Click here Now : Arthrtis Treatments in Abbotsford

3. Injury or Accident

Knee injuries are very common, especially in people who play sports or do heavy physical work. Injuries may include:

• Torn ligaments

• Meniscus tears

• Fractures

• Sprains

Even a small fall can damage the knee and cause long-lasting pain if not treated properly.

4. Overuse of the Knee

Using the knee too much can lead to pain. This often happens when people:

• Walk or run for long hours

• Stand for a long time

• Do repeated movements like bending or lifting

Overuse can cause inflammation around the knee, leading to pain and discomfort.

5. Being Overweight

Extra body weight puts more pressure on the knees. Every step adds stress to the knee joints. Over time, this can damage the cartilage and cause pain. Being overweight also increases the risk of arthritis.

6. Weak Muscles

Weak thigh and leg muscles cannot support the knee properly. When muscles are weak, more pressure goes directly to the knee joint. This can cause pain, especially while standing up, walking, or climbing stairs.

7. Poor Posture and Body Movement

Wrong posture while sitting, standing, or walking can also cause knee pain. Sitting cross-legged for long periods, bending the knees the wrong way, or wearing footwear without proper support can affect knee health.

8. Medical Conditions

Some health problems can also cause aching knees, such as:

• Vitamin D deficiency

• Bone weakness

• Infections

• Nerve problems

In these cases, knee pain may come with other symptoms like swelling, fever, or numbness.

When to See a Doctor

You should see a doctor if:

• Knee pain lasts more than a few days

• There is swelling or redness

• You cannot walk properly

• Pain increases with time

Early treatment can prevent serious problems later.

Conclusion

Aching knees can happen for many reasons, including aging, arthritis, injury, overweight, or weak muscles. Knowing the cause is the first step toward relief. Simple lifestyle changes like maintaining a healthy weight, exercising regularly, and using proper posture can help protect your knees. If the pain does not improve, medical advice is always the best option.
