Hi Angee, There can be two possibilities-
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:
Treatment depends on how badly the knee is affected by the loss of the ligament . Severe injury may need a reconstruction operation.
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.
