If you’ve ever experienced knee pain after landing wrong when jumping or missing a step on stairs, you may have been suffering from a hyperextended knee. This injury occurs when the knee is bent back too far, causing damage to the ligaments and cartilage of the knee. Knee hyperextension can range from mild to severe. In extreme knee hyperextension, it’s possible for knee ligaments such as the anterior cruciate ligament (ACL) to tear completely.
A hyperextended knee is common in athletes that take part in contact sports, but the injury can occur in anyone from children to adults. Symptoms of knee hyperextension can include:
- Diminished range of motion
- Fluid accumulation around the knee joint, called “water on the knee”
- Inflammation around the knee joint
- Instability in the knee joint
- Knee bruising
- Knee pain
Injuries that Can Accompany a Hyperextended Knee
Severe hyperextension can cause serious damage to the major ligaments of the knee. If you experience hyperextension, it is extremely important to get a thorough physical exam and diagnosis from a medical professional. Imaging may also be necessary to determine if more serious soft tissue injury has occurred.
Signs that you may have sustained a major ligament injury include:
- A popping sensation at the time of knee injury
- Inability to put weight on the affected leg
- Swelling that sets in immediately after the injury
- Warm or red inflammation due to bleeding within the joint
