Knee pain is one of the common clinical symptoms, and its causes involve multiple tissue structures such as bones, muscles, ligaments, cartilage, and synovium. The following are some common causes of knee pain:
1. Traumatic injuries: External impacts such as falls, car accidents, or collisions during sports may cause fractures, dislocations, or soft tissue injuries, leading to knee pain.
2. Overuse: Frequent exercise, prolonged standing or walking, and excessive body weight may overburden the knee joint, causing pain and inflammation.
3. Osteoarthritis: This is the most common cause of knee pain, commonly seen in middle-aged and elderly individuals. Osteoarthritis results from gradual wear of the joint cartilage, leading to increased friction between bones, causing pain and joint dysfunction.
4. Meniscus injury: The menisci are two C-shaped cartilage pads located between the femur and tibia, acting as cushions. Sprains or impacts during sports may cause meniscal tears, resulting in knee pain.
5. Ligament injury: The stability of the knee joint mainly depends on four major ligaments: the anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament, and lateral collateral ligament. Strain or rupture of any of these ligaments can lead to knee instability and pain.
