Hi Angee,
There can be two possibilities-



  • ACL tear- Anterior crociate ligament tear which joins the back of the inside of the thighbone to the outside front of the shinbone.

When the ACL is completely ruptured, it is common to hear a distinct popping sound. You may also feel something snap inside the knee. If the knee appears loose, it is usually a sign of an ACL injury. Other symptoms include:



  • pain and tenderness

  • almost immediate swelling

  • an unstable knee, making it difficult to walk

  • the knee locking during movement

Treatment depends on how badly the knee is affected by the loss of the ligament . Severe injury may need a reconstruction operation.



  • Patellar tendon rupture - The tendon that connects the kneecap to the thigh muscle (patellar tendon) can be torn if the knee is bent too far back. A popping or tearing sound may occur. There is also pain, swelling and weakness of the joint. With the knee protected in a knee brace, a partial tear of the tendon can heal within several weeks. A complete tear may require surgery.

Either of the two injuries require an Orthopaedic examination as soon as possible. If you are at home, take some pain killers like Tylenol or Mortin, do not move your affected knee joint or put weight on it and contact your doctor.
