Various causes of knee pain that you need to be aware of

The knee supports your body whether you are walking, running, or sitting and squatting. If you have knee problems, the pain will certainly hinder all your movement. What causes your knee to hurt during activity? Check it out below.

Causes of knee pain when straight or bent

There are various causes for your knee to hurt. If while stretching your legs, sitting, squatting, you experience the following symptoms:

• Pain when bending the knee.
• Feet or calf feels limp
• Stiff knees when jumping, squatting, sitting, climbing stairs.
• Feeling pain under the kneecap when standing or just standing still.

It could be that you have patellofemoral or jumper's knee. In many cases, patellofemoral pain syndrome is caused by strenuous physical activity that puts repetitive stress on the kneecap (patella), causing knee pain and weakness when used for activities. For example after excessive exercise that involves knee movements such as running, jumping, and lifting weights.

This condition is indeed more common in sports activists, but everyone can experience this if they have an accident or injury.

Patellofemoral pain syndrome can also be caused by the position of the kneecap being out of the trochlear groove (the cushion), resulting in the patella being pushed to one side when the knee is bent. This disorder can cause increased pressure between the back of the patella and trochlea, and irritate the surrounding soft tissue.

Another cause of knee pain

Apart from injuries and excessive use of the knee during activities, there are many other causes of knee pain that can interfere with activities when standing, sitting, or squatting.

Other causes of sore knees include:

• Osteoarthritis (calcification of the joints). Damage to the knee joint can be caused by natural aging, obesity, trauma, or other factors.
• Bursitis: inflammation caused by repeated use of the knee until the cartilage of the knee is damaged.
• Baker's cyst: buildup of synovial fluid (fluid that lubricates the joints) behind the knee.
• Dislocation: displacement of the kneecap due to trauma
• Meniscus tear: When one of the ligaments in the knee breaks or tears, you can experience pain in the knee when you move it.
• Osteosarcoma (bone cancer) can also occur in the knee.
