Structure of the knee
The knee is a complete structure composed of the thigh bone, tibia, and patella, and also includes ligaments, cartilage, meniscus, bursa, and fluid. Any damage or inflammation of any component will cause knee pain.
Common causes of knee pain
- Osteoarthritis: As age increases, the knee cartilage degenerates and wears out, which is a common type of knee disease.
- Anterior cruciate ligament injury (ACL tear): Most of them occur during exercise, when the knee suddenly changes direction and causes the ligament to tear.
- Fracture: When an accident occurs, the knee is over-twisted or slipped due to external force.
