A "locked" knee, characterized by an inability to fully straighten or bend the leg, can be incredibly debilitating. This isn't a simple lock like a door; rather, it's a symptom of an underlying issue within the knee joint. This article explores the potential causes and offers strategies for addressing a locked knee, emphasizing the importance of professional medical evaluation. It's crucial to understand that this information is for general knowledge and should not replace advice from a medical professional.

What Causes a Locked Knee?

Several factors can contribute to a knee locking sensation. These include, but are not limited to:

• Meniscus Tear: A meniscus tear, involving the cartilage pads within the knee, is a common cause. A piece of torn meniscus can get trapped in the joint, hindering movement. As explained by [insert citation here - find relevant Sciencedirect article on meniscus tears and knee locking], "Meniscal tears are frequently associated with locking, giving way, and pain in the knee." This often involves a sudden twisting or forceful impact on the knee.

• Ligament Injury: Damage to the ligaments, which stabilize the knee, can also cause locking. Instability from a ligament injury can lead to malalignment, potentially causing structures to impinge on each other.

• Osteoarthritis: This degenerative joint disease, characterized by cartilage breakdown, can cause bone spurs and inflammation, restricting joint movement. [insert citation here - find relevant Sciencedirect article on osteoarthritis and knee locking] may provide further insight into the mechanical limitations imposed by osteoarthritis.

• Loose Bodies: Fragments of cartilage, bone, or other tissue can break off and float within the joint. These "loose bodies" can become lodged, preventing full extension or flexion.

• Plica Syndrome: The plica are folds of tissue in the knee joint. Irritation or inflammation of these folds (plica syndrome) can cause pain and restricted movement, mimicking a locked knee.

• Baker's Cyst: A Baker's cyst is a fluid-filled sac behind the knee. While not directly causing the locking, it can contribute to stiffness and restricted movement, potentially mimicking a locked feeling.

What Should You Do If Your Knee Locks?

Do NOT attempt to force your knee. This could exacerbate the injury. Instead:

1. Rest: Avoid activities that aggravate the pain and swelling. Ice the area for 15-20 minutes at a time, several times a day. Elevation can also help reduce swelling.

2. Seek Medical Attention: A doctor or physical therapist can accurately diagnose the cause of your locked knee through a physical examination and potentially imaging tests (X-rays, MRI). Early diagnosis and treatment are key to preventing long-term problems.

3. Follow Medical Advice: Your healthcare provider will recommend the appropriate treatment, which may include:

   • Physical therapy: To improve range of motion, strengthen surrounding muscles, and improve joint stability.
   • Medication: Pain relievers and anti-inflammatory drugs can help manage pain and inflammation.
   • Surgery: In cases of significant damage, such as a complex meniscus tear or ligament injury, surgery might be necessary.

Additional Tips and Considerations:

• Prevention: Maintaining a healthy weight, strengthening leg muscles, and using proper techniques during physical activity can help prevent knee injuries.
• Listen to Your Body: Don't ignore persistent knee pain or locking. Early intervention often leads to better outcomes.
• Gradual Return to Activity: Once your knee has healed, gradually increase activity levels to avoid re-injury.
