2. Knee Arthritis

Arthritis, which is defined as “joint inflammation,” affects millions of individuals worldwide. There are more than 200 distinct forms of arthritis, but osteoarthritis is the most frequently resulting in knee discomfort while bending. 

3. Osgood Schlatter

It is the common cause of knee pain when bending the knee, especially in teenagers. The bones grow quicker than the soft tissues, which leads to more tension through the patellar tendon resulting in damage to the underlying bone.

4. Dislocated Kneecap

A dislocated kneecap is when the kneecap moves out of the original position, leading to knee pain and swelling. 

5. Osteoarthritis

It is the common cause of knee pain after passing the age of 50. When you’re active, this ailment causes the knee joint to hurt or bulge. Osteoarthritis-affected joints might become stiff in the morning as well. 

6. Meniscus Tear

The meniscus is a unique, exceptionally thick layer of cartilage that lines the knee joint and serves as the knee’s cushion and protector. It transmits the forces through the knee. 

7. Patellar Tendonitis

Inflammation & micro tears in the patellar tendon below the kneecap can cause a lot of knee pain, mostly after long-duration jumping or kicking.

Types of Knees Pain While Bending

1. Knee Pain with “Locking” in the Joint

There are 2 ‘C’ shaped cartilage pieces known as menisci located inside the knee joint. The role of cartilages is to maintain the surfaces of the upper& lower leg bones from grinding against each other. The cartilage is frequently damaged due to trauma, such as landing a jump or twisting your knee.

You can even experience difficulties moving around, having trouble walking, or even feel like a joint is “locking.”

2. Pain Behind the Kneecap

Soft cartilage under the kneecap creates a gliding surface between the bones. Pain and irritation may develop if it softens or fades away. When the quads strengthen and stretch, lengthening the hamstrings and calf will help reduce the injury risk. 

3. Pain & Tenderness on the Outside of the Knees

The iliotibial band extends from the outside of the hip to the outside of the knee. Knee extension and lack of tissue flexibility can lead to Iliotibial Band (ITB) syndrome. It can put tension on the outside of the knee and may lead to knee pain when bending. 

4. Pain with a Pop

MCL and ACL are crucial stabilizing elements in the knee that keep the joint from moving from side to side. Trauma, such as twisting, turning, halting suddenly, or if the knee is forced side to side, can easily result in an injury. You may feel the pain with a popping sensation. 

Correct alignment can aid in preventing such injury. Here, physical therapy can be useful for getting relief from pain. The doctors may use bracing for supporting & stabilizing the knee at the time of recovery.
