What injuries can you get from hyperextending your knee?

During hyperextension, the knee joint bends the wrong way, which often results in swelling, pain and tissue damage. In severe cases, ligaments such as the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), or popliteal ligament (the ligament along the back of the knee) may be sprained or ruptured.

Can you tear your meniscus from hyperextension?

Common causes of a traumatic meniscus tear include injuries that involve twisting the leg with the foot planted, hyperextension of the knee, and hyperflexion of the knee. The medial meniscus is more likely to be involved than the lateral, and these traumatic tears tend to affect athletes and people under the age of 40.

What happens if a hyperextended knee goes untreated?

When the knee hyperextends, stress is placed on the knee structures, particularly at the back of the knee. In severe cases, one or more of the knee ligaments may be over-stretched and either partially or completely tear. This can lead to long-term knee instability if left untreated.

How do I know if I have tendon damage in my knee?

A loud pop or snap during the injury. Swelling within the first 24 hours after the injury. A feeling of looseness in the joint. Inability to put weight on the joint without pain, or any weight at all.

What ligament keeps knee from hyperextending?

This ligament prevents the tibia from moving too much and going behind the femur. A PCL injury (which may also be called hyperextended knee) is a partial or complete tearing or stretching of any part of the posterior cruciate ligament.

How would you know if you tore your ACL?

Signs and symptoms of an ACL injury usually include:

1. A loud pop or a “popping” sensation in the knee.
2. Severe pain and inability to continue activity.
3. Rapid swelling.
4. Loss of range of motion.
5. A feeling of instability or “giving way” with weight bearing.

How serious is a hyperextended knee?

A hyperextended knee can damage ligaments, cartilage and other stabilizing structures in the knee. Young children have softer bones because they’re still growing, so a hyperextended knee can result in a chip of bone being pulled away from the main bone when the ligaments stretch too far.

Should I go to the doctor for a hyperextended knee?

A person must seek medical attention as soon as possible following the injury and follow all recommended treatment advice for the best chance of full recovery. It can be difficult for athletes and active people to rest, but it is necessary for the best recovery from a hyperextended knee.

Does a hyperextended knee Need surgery?

Treatment for severe cases In more extreme cases, a hyperextended knee will require surgery to fix the ligaments or alignment of the knee. A torn anterior cruciate ligament (ACL) is the most common complication, but other tendons and structural supports can be damaged.
