<\/a><\/figure><\/div>\n\n\nSymptoms of the hyperextended knee can include swelling, severe knee pain, and visible bruising. A hyperextended knee is usually easy to identify when it happens. An individual usually feels the knee bend backward out of line with the leg. As hyperextension of the knee can develop to varying degrees of severity, the manifestations of the injury based upon the individual athlete\u2019s body and the overall strength of the knee joint. Typical symptoms of knee hyperextension comprise:<\/p>\n\n\n\n Instability of the Knee-<\/strong> Following a hyperextension injury, you may notice instability in your knee joint. Many individuals address feelings of their leg \u201cgiving out\u201d while stepping or having trouble standing on one leg.<\/p>\n\n\n\n Pain-<\/strong> A localized pain is expected following hyperextension of the knee joint. Pain can vary from mild to severe and typically increases when ligaments or other structures are damaged or torn. Pain is specified as a mild to a sharp pain in the back of the knee or pinching pain in front of the knee joint.<\/p>\n\n\n\n Decreased Mobility-<\/strong> You may have trouble flexing or straightening your leg after a hyperextension injury. This could be because of swelling around the knee, which can inhibit your knee’s movement and damage to the internal structures such as the ACL, PCL, popliteal ligament, or meniscus. This will reveal a shortened range of motion because of weakness in the joints, swelling, and pain.<\/p>\n\n\n\n Swelling and Bruising-<\/strong> Following an injury, you may recognize immediate or delayed swelling and bruise of the knee and surrounding area. Fluid accumulation within the knee joint is typical after hyperextension of the knee. This can be mild or more severe, and it’s your body\u2019s way of responding to the injured tissues.<\/p>\n\n\n\n If the hyperextension of the knee is traumatic enough to cause harm to ligaments, cartilage, or other soft tissues, bruising may develop on the skin. Knee hyperextension can lead to a severe or minor injury, individuals experiencing these symptoms may benefit from seeking medical attention.<\/p>\n\n\n\n Hyperextension typically occurs when the knee absorbs strong, sudden force while they straightening the leg. When an excessive amount of force the knee into extension, causing soft tissue damage, swelling, and potentially tears or strains of the ACL, MCL<\/a>, LCL, or PCL. Common causes of knee hyperextension include:<\/p>\n\n\n\n The method by which it causes a knee hyperextension can predict the severity of the condition. In minor cases, an athlete will notice small amounts of pain or swelling. In traumatic injury, however, hyperextension of the knee can also cause damage to the encompassing ligaments, cartilage, and soft tissues.<\/p>\n\n\n\n Other Causes Include:<\/strong><\/p>\n\n\n\n The history will offer clues to the diagnosis as a prior knee injury. A physical examination will help confirm and grade the injury, including joint mobility, visible injury, bruising or swelling, torn ligaments, and locking of the joint. Diagnosing knee hyperextension will vary from patient to patient because the severity of the injury is broad. Others who suffered a minor hyperextension may have mild swelling and slightly reduced mobility.<\/p>\n\n\n\n Imaging is required in severe injury and particularly if surgery is contemplated. MRI and X-ray imaging are typically performed. Athletes seeking medical attention for a potentially hyperextended knee will likely have different experiences based on the severity of their injury. Most diagnostic processes will involve the following factors:<\/p>\n\n\n\n Patient History<\/strong><\/p>\n\n\n\n A physician will consider the medical history of an athlete before advising treatment. For instance, an athlete with prior knee injuries is also more vulnerable to a more severe injury.<\/p>\n\n\n\n Physical Examination<\/strong><\/p>\n\n\n\n The physical examination will aid the physician in determining the severity of the injury and if further imaging is required. During a physical examination, your physician will check the athlete\u2019s range of motion by moving the leg forward and backward. In some patients, the leg is locked indicating a more severe injury. Throughout this process, the doctor also will check for visible bruising or swelling which will result in a torn ligament or other internal damage.<\/p>\n\n\n\n
According to the American Journal of Sports Medicine<\/a>, female athletes have increased joint instability, turning them at a higher risk of knee injury than men, chiefly those who take part in high-risk sports. It\u2019s usually the result of a direct blow to the knee or forces spawned during a quick deceleration or stop. In these occurrences, a large amount of stress is put upon one or more major ligaments of the knee such as medial collateral ligament (MCL), lateral collateral ligament (LCL), anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) or popliteal ligament (the ligament along the back of the knee) may be strained or ruptured.<\/p>\n\n\n\nHyperextension Knee Symptoms<\/h2>\n\n\n\n
