Knee pain is a common complaint that can arise from various conditions or injuries. It can affect people of all ages and activity levels, with symptoms ranging from mild discomfort to severe pain and disability. Understanding the underlying cause is crucial for appropriate treatment and management.
Common Causes of Knee Pain
- Injuries
- Ligament Injuries: Damage to the knee ligaments, such as the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), or lateral collateral ligament (LCL), can cause significant knee pain. ACL injuries are particularly common in sports.
- Meniscus Tears: The menisci are cartilage pads that cushion the knee joint. Tearing a meniscus can occur during activities that involve twisting or turning the knee.
- Tendinitis: Inflammation of the tendons around the knee, often due to overuse. Common types include patellar tendinitis (jumper’s knee) and iliotibial band syndrome.
- Fractures: A break in the kneecap (patella) or other knee bones due to trauma can cause acute pain and swelling.
- Dislocation: The kneecap can slide out of place, causing intense pain and difficulty moving the knee.
