Causes Diagnosis Management
 

Direct injuries

  • Indirect injuries caused by twisting the flexed knee.
  • Occurs mostly in athletes and sports persons
  • Bucket handle tear of meniscus is most common. The handle is caught in the intercondylar notch of tibia and causes pain which stops any form of knee activity and the knee then swells and is flexed and cannot be extended (knee locking).
  • After the initial stage, spontaneous unlocking may occur, which is then followed by recurrence.
  • Parrot beak tear follows when the handle is torn. This eliminates knee locking but pain occurs anytime cartilage is caught between the condyles of femur and tibia.
