Your doctor will ask you when and
ankle sprain occurred and ask about any prior
Next, your doctor will examine your foot, ankle, and
lower leg and even your knee to see if any other injury occurred. He or she
may ask you to move your foot up and down and to take a few steps if possible.
Your doctor will then carefully try moving your foot and ankle to see if the
ligaments are intact and what movements cause pain.
The posterior cruciate ligament (PCL) is a ligament within the knee. Ligaments are tough bands of tissue that connect bones.
The PCL -- similar to the anterior cruciate ligament (ACL) -- connects the thigh bone (femur) to your shin bone (tibia). Although it is larger and stronger than the ACL, the PCL can be torn.
PCL tears make up less than 20% of injuries to knee ligaments. Injuries that tear the PCL often damage some of the other ligaments or cartilage in the knee, as well. In some cases,...
If your sprain
is mild, an
X-ray may not be taken. If your sprain is more severe,
you may need X-rays to evaluate the ankle. X-rays can help your doctor find
out whether you have any ligament tears, broken bones, or bones that have moved
out of their normal positions.
X-rays are often taken for
children because of potential injury to the bone's
growth plate and possible disruption of normal growth.
Doctors may take X-rays of both ankles so they can compare the injured ankle
with the one that is healthy.
