Bending knee pain:Causes and symptoms

Knee injuries are the most common causes of knee pain when bending. Ligament tears, sprains and straining of the muscles of the knee cap can lead to injuries. Injuries can be caused by accidents, forceful blows to the knees or abnormal bending or twisting of the knees during physical activities. Some of the most common knee injuries that cause knee pain when bending these joints include:

Lateral meniscus tear

This is a tear to the meniscus cartilage. The meniscus, a two disc-shaped cartilage, is between the femur and tibia bones of the knee. When there is a tear or injury to it, caused by twisting or heavy weight bearing activities, the lateral meniscus tear occurs. This kind of injury can also be caused by degenerative bone diseases in elderlies.

Symptoms: Strong Knee pain while running or jogging, swelling of the knee joints, buckling in the knees and popping sounds experienced while bending the knee. One may be unable to flex the knees or may even experience extreme pain while bending.

Treatment: Based on severity and the cause of meniscus tear, the doctor can suggest appropriate treatment for this injury. Anti-inflammatory medication, together with rest and elevation are appropriate if the tear is caused by injury. Surgery may be necessary if the tear does not improve.


Runner’s Knee

This is an aching pain around the kneecap front’s part, mainly caused by repeated knee bending, misalignment of the kneecap, direct blow, weak thigh muscles or even flat feet.

Symptom: include knee pain when bending while engaging in squatting, kneeling, running and other such-like activities. There is also swelling along with a grinding sensation when walking or flexing the knees.

Treatment: You can use rice treatment that involves compression, rest and elevation to relieve the pain. Surgical treatment such as arthroscopy or knee alignment can help in recovering runner’s knee injury.

Other Knee Injuries that cause knee pain when bending include:

  1. Jumper’s knee injury– this is related to sports, and mainly affects the patellar tendons.
  2. Knee ligament– this pain is common in athletes, and can cause extreme when bending or flexing the muscles.
  3. Bursitis– this is inflammation of the bursa in the knee joints due to bending, kneeling, excessive friction or squatting.


In addition to knee injuries, other causes of knee pain while bending include:

Sudden movements– jerky movements, particularly when playing sports contribute significantly to development of this pain. The knee, being a joint, is vulnerable to sudden pain movements.

Osteoarthritis– this is a degenerative condition that is normally seen in people over 50 years. This disorder is natural, and it happens due to deterioration of cartilages caused by constant use.

Repeated activities– if you engage the knees in strenuous and repetitive activities such as jumping jacks with no resting, the knees can strain a lot.

Tendon inflammation– this is another factor that causes severe pain. If the tendons are overused, they become susceptible to infections.

The symptoms of these causes of knee pain while bending are more or less the same to the other conditions discussed above. But additionally, you may experience sharp pains when bending, sitting on a chair, going up or down a stair case or when sitting cross-legged.



Knee Pain Exercises as a form of treatment

Most forms of treatments have been discussed above, and they apply to almost every cause of pain and symptoms. In the case of serious pain, it is highly recommended that you visit a physician for further recommendations on treatment or surgery.

You can also try water aerobics for knee strength, but it is important that you consult a physician. Besides these, you can also adopt therapeutic exercises. You can start by lying flat on the ground and stretch the legs outward with the feet, slowly.
