What is hyperextension range of motion?
The two basic ranges of motion for most joints are flexion (bending) and extension (straightening). Hyperextension means that there’s been excessive movement of a joint in one direction (straightening). In other words, the joint has been forced to move beyond its normal range of motion.
What causes hyperextension knee?
Common causes of knee hyperextension include: Pushing the femur or patella over the tibia and placing excess stress upon one or more of the major ligaments within the joint. This sort of impact might be experienced by a basketball player stopping unexpectedly and placing all of their weight on one leg to do so.
How does a hyperextended knee look like?
Hyperextended knee is often pretty easy to identify. The knee is bent upwards beyond the straight position it’s supposed to have. It looks like when your children bend the legs of their barbie dolls in the wrong direction.
What damage can hyperextension cause?
In older children and adults, forceful hyperextension may tear one of the knee ligaments, particularly the anterior cruciate ligament (ACL).
What is knee Hyperflexion?
Hyperflexion of the knee puts direct shear and compressive force on the posterior tibia. This can result in ligament injuries combined with avulsion fractures of both posterior meniscal attachments. Arthroscopic treatment is a practicable technique for this type of injury.
How many degrees can the knee extend?
A fully bent knee will max out at about a full range of motion of 135° degrees of flexion. As a general rule, a knee flexion of about 125° will allow you to carry out most normal activities. For daily living, a minimum flexion of around 105°-110° is required.
How long does a minor hyperextended knee take to heal?
Recovery from a mild to moderate sprain following a knee hyperextension injury can take 2 to 4 weeks. It’s important during this time to limit activities that can further strain the knee and to continue to manage swelling and pain.
How serious is 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.
What is a hyperflexion injury?
Whiplash is defined as a sudden injury to the neck whereby the neck is forced into rapid hyperflexion (bending forwards) and hyperextension (bending backwards). This rapid motion to the cervical spine results in soft tissue sprain/strain complications.
What is normal knee ROM?
Should you stretch a hyperextended knee?
If you have injured yourself or if you want to avoid injury, then you can try a few hyperextended knee exercises and stretches to help build or rebuild strength.
What is hyperflexion of the knee?
A hyperextended knee is an injury that happens when your knee is bent backward beyond its usual limit. Sports injuries and other traumas apply a lot of force to your knee’s connective tissue (the tendons, ligaments and cartilage that hold it in place and help it move).
