I Can T Straighten My Knee Without Pain

Cant Fully Extend Knee Without Pain

Why can’t I straighten my knee?

Cant fully extend knee without pain? Many people experience this problem at some point in their lives. The pain may be caused by an injury, such as a ligament tear, or by a condition, such as arthritis. Treatment depends on the underlying cause. In some cases, the problem can be resolved with physical therapy or surgery.

It may be necessary to straighten the knee in order to avoid pain. The knees ability to move is significantly hampered by the injury. If there is a serious knee injury, you may require medical attention. The purpose of this article is to provide a brief explanation of the causes of knee straightening issues. In some cases, there is also a tear of the knees kneecap that complicates things. There are a variety of other reasons why a knee swell may occur after an injury, including a build up of fluid within the knee.

Is Knee Surgery Necessary To Repair A Torn Meniscus

More serious meniscus tears may not heal on their own. If your injury doesnt improve with RICE, NSAIDs and physical therapy, your healthcare provider may recommend arthroscopic surgery.

Surgery is a very effective way to repair a torn meniscus. If the tear is too big to repair, your surgeon may remove all or part of the meniscus. After recovery, your knee will be more stable, and youll be less likely to develop additional knee problems.

Torn Anterior Cruciate Ligament

You hear a pop and can’t move after you suddenly change direction — often while playing soccer, football, or basketball. You may have torn your ACL, which connects the femur and the tibia and prevents the tibia from moving too far forward. Your knee will hurt and swell and feel unstable.

You can tear or strain any of the tissues that hold your knee together: Ligaments connect bones to each other tendons connect muscle to bone. Irritated tendons from using them too much? That’s tendinitis.

Ligamentous Tears Of The Knee

The knee has four major stabilising ligaments that give it stability through range. One I previously mentioned is the ACL. If you have tears in the other 3 ligaments, you may also experience giving way of the knee.


Right next to the ACL, on the inside of the knee, we also have a PCL. This ligament helps to stop your shin bone from hyperextending.

This ligament is usually injured with dashboard car injuries, where the shin is forced into the dash and the knee hyperextends.

If your PCL is torn, you wont feel stable when you fully straighten the knee and the knee can give out backwards and buckle.


The major inside stabiliser of the knee is your MCL. This ligament stops the knee from buckling inwards.

The MCL is damaged when your knee is forced inwards. As you are forced into being knock kneed, the MCL is stretched and can partially or fully tear.


Much like the MCL, your LCL stops the knee from bowing outwards. It is put under strain when there is a force that pushes the knee out, like a kick to the inside of the knee.

Reasons You Cant Straighten Knee

Severe knee injuries can cause loss of full motion in your knee. As a result, you feel unbearable pain when trying to straighten your leg.

Knee pain has varying causes and intensities. For instance, you may not straighten your knee because you feel like something is blocking it from moving. Another reason could be severe pain and swelling from an injury when you extend your knee.

The treatment of knee injuries depends on your lifestyle and the intensity of the pain. You can also opt for cell-based therapy as a low-pain treatment for your knee issue.

The back of the knee can be painful if a person straightens their leg due to a variety of issues such as blood clots, muscle or tendon injuries, arthritis, and cysts.

  • Activities that stress the knee again and again, especially those with twisting motions.
  • A traumatic injury to the knee, such as a blow that pushes the kneecap toward the outer side of the leg.

You Notice An Obvious Deformity

If you notice your knee jutting outward in a way it never has before, take note. A dislocated or fractured patella can cause injuries like this, explains Brian Schwabe, C.S.C.S., board-certified sports physical therapist based in Los Angeles.

While some deformities occur over time, when the deformity is a result of an injury, it could be the result of a fracture or chronic wear on the knee joint. If you are already experiencing any kind of misalignment in your lower extremities, then you could be more prone to this type of injury.

Basics Of Torn Meniscus

A torn meniscus is a tear in the cartilage of the knee. The meniscus functions to improve the fit between the femur and the tibia, to absorb shock and distribute load in the knee, and to help move lubricating fluid around the knee. The meniscus can tear from either trauma or injury or from degeneration.

The knee is made up of the femur , the tibia , and the patella . Ligaments hold the bones of the knee together and the patella lies in the quadriceps muscle in front of the knee.

Between the femur and the tibia are two pads, one on the medial side of the knee and one on the lateral side of the knee. Each of these pads is called a meniscus. See Figures 1 and 2.

The meniscus is made of fibrocartilage, which gives it a rubbery texture. Within the meniscus there are also fibers of collagen that help maintain the shape of the meniscus. The meniscus has blood supply only at its outer attachments. Therefore, about 4/5 of a meniscus has no blood supply and therefore cannot heal if it is torn.

Osteoarthritis Or Bone Spur

Knee wonât straighten after standing?

Osteoarthritis is a common form of arthritis, affecting more females than males. It is a joint condition in which the cartilage protecting the knee slowly tears down, resulting in severe pain, swelling, and restricted knee mobility.

A bone spur or osteophyte is also a reason you cant straighten the knee. It is when an additional, pointed bone grows along the joint edges due to trauma or arthritis. Bone spurs usually pose no symptoms, but they can restrict your full knee extension in severe cases.

Do You Pain In Back Of Knee

Behind the knee, the flesh of your leg feels soft and thickly padded. This region known as the poplitealis home to a number of blood vessels that feed your lower leg. You can even feel your pulse in this region if you can locate your popliteal artery. Pain in this region of the knee is sometimes the result of damage to or inflammation of these soft tissues.

What Is A Torn Meniscus

A meniscus is a disk-shaped piece of cartilage that acts as a shock absorber inside a joint. Each knee has one lateral meniscus under the outer knob of the thighbone and one medial meniscus under the inner knob of the thighbone. Each meniscus acts as a natural cushion between the thighbone and shinbone . The two cushions prevent excess wear and tear inside the knee joint by keeping the ends of the two bones from rubbing together. Each meniscus also absorbs much of the shock of jumps and landings and helps to distribute joint fluid evenly to lubricate and nourish the knee.

In the United States, a torn meniscus is the most common reason for knee surgery.

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. Its also possible, as with any pain you feel in this complicated part of the body, that the pain is referred from deeper in the joint, as with a tear in the knees cartilage.
