What Causes Knee Pain When Bending

Who Gets Pfp Syndrome

Bending or Kneeling: What Causes Knee Pain

Patellofemoral pain syndrome usually happens in people who do sports that involve a lot of knee bending and straightening, such as running, biking, and skiing. It also can happen to people, particularly young women, who do not do a lot of sports.

PFP syndrome is more common in women and happens most often to teens and young adults.

Tight or weak leg muscles or flat feet can make someone more likely to get PFP syndrome.

Above Or Around The Kneecap

If bending causes pain in front of, above or around the kneecap, you may be experiencing:

  • Patellofemoral pain syndrome. Commonly known as runners knee, patellofemoral pain syndrome develops when the tissues around and under the kneecap become irritated and inflamed. Runners knee causes pain, stiffness and grinding or creaking sounds in the knee.
  • Quadriceps tendinitis. The quadriceps tendon sits above the knee and connects the quadriceps muscle to the kneecap. Overuse can cause the tendon to become thickened, inflamed and torn, leading to knee pain and stiffness.
  • Patellar tendinitis. The patellar tendon sits below the knee and connects the shinbone to the kneecap. Overuse can cause the tendon to become thickened, inflamed and torn, leading to knee pain and stiffness.
  • Bursitis. The knee joint contains several fluid-filled sacs that cushion the bones, ligaments, tendons and muscles. When one or more of the bursae becomes inflamed, it can cause knee pain and stiffness over the kneecap.

Who Is At Risk For Pfs

PFS often impacts athletes and those who engage in running, basketball, and other sports. Women are especially vulnerable to PFS, particularly at a younger age. This thought to be partially due to the greater likelihood of patellar malalignment in females, in addition to muscular imbalances.

PFS is most symptomatic during positions when the knee is flexed, such as after sitting for a prolonged period time, exercises that required deep squatting, or, most commonly, climbing stairs. Strengthening the muscles around your hips and quadriceps and stretching your iliotibial band, hamstrings, and quadriceps can help relieve strain on your knee.

Do You Have Pain Above The Kneecap

Above the kneecap, your patella is secured by a strong tendon that connects the bone to the powerful muscles in your thigh. Pain in this location can indicate that youve sprained or torn this tendon.

Understanding The Anatomy Of The Knee

To understand why the knee hurts when bent, we first must understand its anatomy and how it works. The bones of the lower and upper legs are connected by the knee joint.

Proper functioning of this joint also enables us to stand, walk, squat, jump, and turn. Lets examine the knee joint in detail.

Other Causes Of Knee Pain When Bending

Other less common causes of knee pain when bending include:

  • Iliotibial Band Syndrome : Irritation and inflammation of a thick fibrous band on the outer side of the thigh and knee. It usually develops from overuse and most frequently affects runners. Sending bending knee pain from ITBS tends to be on the outer side of the knee and there may be a popping/grinding sensation as you bend the knee
  • Osgood Schlatters: A common cause of bending knee pain in teenagers usually associated with sudden growth spurts where the bones grow quicker than the soft tissues leading to excessive tension through the patellar tendon which damages the underlying bone.

    Why Is My Knee In Pain When Bending It?
    Runners Knee

    Runners knee is a painful condition that develops as a result of repeated bending of the knee joint. However, it can also occur because of poor alignment, a direct blow to the knee, or due to flat feet or weak thigh muscles. Pain from runners knee is usually just below or to the sides of the kneecap in the front. Symptoms include swelling around and behind the kneecap, knee pain when bending, possible crepitus, or cracking and popping noises in the knees when walking. Runners knee pain usually begins gradually and increases in severity as symptoms worsen.


    Each of your knees has fluid filled sacs called bursa, which cushion and protect the structures of the knees. Bursitis occurs when the bursa become inflamed when kneeling, squatting, or in the presence of excess friction in the joint. Repetitive or prolonged kneeling or falling onto the knee can also cause inflammation of the prepatellar bursa below the kneecap on the front of the knee. Excess fluid in the knee joint that seeps back into the bursa can cause swelling and pain on the back of the knee. Although bursitis is not the most severe condition, it can cause significant discomfort.

    Basic Anatomy Of Knee Joint

    Learning the basic anatomy of the knee joint will help you understand the cause of your pain. In addition, you can now relate to the image and understand it way better.

    The knee is one of the bodys largest and most complex joints. The knee joins the femur to the tibia . The smaller bone that runs alongside the tibia and the patella is the other bones that make the knee joint.

    Tendons connect the knee bones to the leg muscles that move the knee joint. Ligaments join the knee bones and provide sufficient stability to the knee.

    • The anterior cruciate ligament prevents the femur from sliding backward on the tibia .
    • The posterior cruciate ligament prevents the femur from sliding forward on the tibia .
    • The medial and lateral collateral ligaments prevent the femur from sliding side to side.
    • Two C-shaped cartilage named the medial and lateral menisci act as shock absorbers between the femur and tibia.

    How Are Knee Problems Diagnosed

    In addition to a complete medical history and physical exam, other tests for knee problems may include:

    • X-ray. This test uses invisible electromagnetic energy beams to make images of internal tissues, bones, and organs onto film.

    • Magnetic resonance imaging . This test uses large magnets, radiofrequencies, and a computer to make detailed images of organs and structures within the body can often determine damage or disease in a surrounding ligament or muscle.

    • Computed tomography scan . This test uses X-rays and computer technology to make horizontal, or axial, images of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.

    • Arthroscopy. A minimally-invasive diagnostic and treatment procedure used for conditions of a joint. This procedure uses a small, lighted, optic tube , which is inserted into the joint through a small incision in the joint. Images of the inside of the joint are projected onto a screen used to evaluate any degenerative or arthritic changes in the joint to detect bone diseases and tumors to determine the cause of bone pain and inflammation.

    • Radionuclide bone scan. A nuclear imaging technique that uses a very small amount of radioactive material, which is injected into the patient’s bloodstream to be detected by a scanner. This test shows blood flow to the bone and cell activity within the bone.

    Ligament Sprain Or Tear

    A ligament sprain or tear can also cause pain when trying to straighten the knee. This is often caused by a sudden twisting motion of the knee joint thats common with cutting and changing directions. Youll feel or hear a pop within the knee and feel as if the knee is unstable and may give out.

    Ligaments are bands of tissue that connect one bone to another and they help stabilize the joint. When they are stretched too far or torn, it can cause pain when they are stretched to normal range of motion.

    The body typically can heal on its own if its an LCL or an MCL tear but it can take nearly 12 weeks to recover. Physical therapy is recommended to work on a range of motion, strengthening, and getting back to normal activities.

    If you suffer an ACL or a PCL injury, then these may require surgery to fix. These do require an MRI to correctly diagnose.
