Preparing for your appointment
By Mayo Clinic staffThe pain and disability associated with an ACL injury prompt many people to seek immediate medical attention. Others may make an appointment with their family doctors. Depending upon the severity of your injury, you may be referred to a doctor specializing in sports medicine or orthopedic surgery.
What you can do
Before the appointment, you may want to write down the answers to the following questions:
- When did you first experience symptoms?
- What were you doing at the time?
- Did you initially hear a loud "pop" sound?
- Did you experience immediate swelling?
- Have your symptoms been continuous or occasional?
- How severe are your symptoms?
- Does anything seem to improve your symptoms?
- What, if anything, appears to worsen your symptoms?
- Does your knee ever "lock" or feel blocked when you're trying to move it?
- Do you ever feel that your knee is unstable or unable to support your weight?
What to expect from your doctor
During the physical exam, your doctor will check your knee for swelling and tenderness — comparing your injured knee to your uninjured knee. He or she also may move your knee into a variety of positions, to help determine if your ACL is torn.
