Knee Pain When Bending And Straightening
What Causes PFP Syndrome? – Patellofemoral (pronounced: peh-tel-oh-FEM-er-ul) pain syndrome is an overuse disorder, These happen when someone does the same movements that stress the knee over and over again. In PFP syndrome, repeated bending and straightening the knee stresses the kneecap.
- It’s most common in athletes.
- Some people with PFP syndrome have a kneecap that is out of line with the thighbone (femur).
- The kneecap can get out of line, or wiggle as it moves along the thighbone, because of muscle weakness, trauma, or another problem.
- If this happens, the kneecap doesn’t glide smoothly over the thighbone when the knee bends and straightens.
The kneecap gets injured and this causes the pain of PFP syndrome.

What does it mean when your knee hurts when you bend it and straighten it?
Causes of knee pain – when bending is a common problem for many people and can have numerous underlying causes. Osteoarthritis, meniscus tears, bursitis, ligament strain, and tendonitis are some of the most common causes. Bone fractures or infections in the joint may also cause knee pain.
Why does it hurt behind my knee when I go from bent to straight?
There are various causes. Your knee joint can wear down as you get older, or you might injure your knee and tear the ligament or cartilage in it. Two common conditions that cause pain behind the knee are a posterior cruciate ligament injury and a popliteal cyst (Baker’s cyst).
Why can’t I fully extend my knee without pain?
There are 7 major causes that prevent your knee from straightening. These include meniscus tears, quadriceps tendon injury, patellar tendon injury, ACL injury, acute swelling, osteoarthritis, patellar dislocation, and muscle imbalance.
Why does it hurt behind my knee only when I straighten my leg?
Posted on: 12 April, 2021 When a person experiences pain in the back of their knee when straightening their leg, it is called posterior knee pain. Pain in the back of the knee, called the popliteal fossa, is common, but there is a wide range of causes, ranging from ligament injury to arthritis.
Why do my knees hurt when I fully extend my leg?
Knee Pain When Straightening Your Leg Your knees are complex joints that bear a lot of your body weight and power your legs for a wide range of activities like walking, running and jumping. It’s important to take care of your knees so you can live out your normal daily life and enjoy physical activities.
- However, despite your best efforts, injuries and conditions can affect your knees, which can limit their use.
- Some conditions cause pain that only when trying to straighten them but not bending them.
- Common conditions that cause this kind of pain include: 1.
- Torn meniscus The meniscus is a small, flat piece of cartilage that rests between the thighbones and shinbones on each side of your knees.
There are two menisci in each knee. They exist to absorb shock in the knees and keep the bones from grinding against one another. A traumatic injury that causes the knee to violently twist can cause a meniscus to tear. A torn meniscus might fold on itself, which can keep you from fully straightening your leg and cause knee pain when you try to do so.2.
Runner’s knee Runner’s knee is the common term for pain around the kneecap. This is a condition in which the tendon that connects your kneecap to your shinbone becomes inflamed from repetitive motions. This can make it painful around the kneecap when you try and fully straighten your leg. Pain around the kneecap is often referred to as runner’s knee since runners frequently bend their knees and absorb a lot of shock from pavement and hard ground, but it is a condition that can affect anyone.3.
Strained muscles Overexertion of the knee can cause one or more of the muscles in your thigh or shin to become stretched or torn. Some strains cause pain that affects your knee whether it’s bent or straight, but some strains might only cause pain when you try to fully straighten your knee.
How do I know if my knee is sprained or torn?
Imaging Tests – Your doctor may recommend an X-ray to rule out another cause of the pain, such as a broken bone, arthritis, or bone spurs, which are small bony knobs that can form in joints when the ends of bones rub together. An X-ray may also show whether fluid has accumulated around a joint, which is a sign of a sprain or strain.
- Our doctors often use ultrasound to diagnose muscle, tendon, and ligament injuries because the imaging test can produce clearer picture of soft tissues.
- Doctors use MRI scan to examine the ligaments to determine the extent of a knee injury.
- The results of these scans can also determine if more than one structure in the knee is affected.
For example, your symptoms may be caused by a knee cartilage injury, or a meniscus tear, An MRI can also help your doctor determine whether a knee sprain is severe, meaning the ligament has partially or fully torn, typically requiring more extensive treatment, including possibly surgery.
