Collateral Ligament (CL) Injury - Aftercare

Description

A ligament is a band of tissue that connects bone to bone. The collateral ligaments are located on the outside of your knee joint. They help connect the bones of your upper and lower leg, inside your knee joint.

  • The lateral collateral ligament (LCL) runs on the outer side of your knee.
  • The medial collateral ligament (MCL) runs along the inside of your knee.

A collateral ligament injury occurs when the ligaments are stretched or torn. A partial tear occurs when only part of the ligament is torn. A complete tear occurs when the entire ligament is torn into two pieces.

More About Your Injury

The collateral ligaments help keep your knee stable. They help keep your leg bones in place and keep your knee from moving too far sideways.

A collateral ligament injury can occur if you get hit very hard on the inside or outside of your knee.

Skiers and people who play basketball, football, or soccer are more likely to have this type of injury.

What to Expect

With a collateral ligament injury, you may notice:

  • Your knee is unstable and can shift side to side as if it "gives way"
  • Locking or catching of the knee with movement
  • Knee swelling
  • Knee pain along the inside or outside of your knee
The location of knee pain can help identify the problem. Pain on the front of the knee can be due to bursitis, arthritis, or softening of the patella cartilage as in chrondromalacia patella. Pain on the sides of the knee is commonly related to injuries to the collateral ligaments, arthritis, or tears to the meniscuses. Pain in the back of the knee can be caused by arthritis or cysts, known as Baker’s cysts. Baker’s cysts are an accumulation of joint fluid (synovial fluid) that forms behind the knee. Overall knee pain can be due to bursitis, arthritis, tears in the ligaments, osteoarthritis of the joint, or infection.    Instability, or giving way, is also another common knee problem. Instability is usually associated with damage or problems with the meniscuses, collateral ligaments, or patella tracking.

After examining your knee, your doctor may send you to have an MRI. An MRI is a device that can take pictures of the tissues around your knee. The pictures will show whether these tissues have been stretched or torn. You also may have an x-ray to see if there is any damage to the bones in your knee.

If you have a collateral ligament injury, you may need:

  • Crutches to walk until the swelling and pain get better
  • A brace to support and stabilize your knee
  • Physical therapy to help improve joint motion and leg strength

Most people do not need surgery for an MCL injury. However, you may need surgery if your LCL is injured or if your injuries are severe and involve other ligaments in your knee.

Self-care at Home

Follow R.I.C.E. to help reduce pain and swelling:

  • Rest your leg. Avoid putting weight on it.
  • Ice your knee for 20 minutes at a time, 3 to 4 times a day.
  • Compress the area by wrapping it with an elastic bandage or compression wrap.
  • Elevate your leg by raising it above the level of your heart.

You can use ibuprofen (Advil, Motrin), or naproxen (Aleve, Naprosyn) to reduce pain and swelling. Acetaminophen (Tylenol) helps with pain, but not swelling. You can buy these pain medicines at the store.

  • Talk with your doctor before using these medicines if you have heart disease, high blood pressure, kidney disease, or have had stomach ulcers or internal bleeding in the past.
  • DO NOT take more than the amount recommended on the bottle or by your doctor.

Activity

You should not put all of your weight on your leg if it hurts, or if your doctor tells you not to. Rest and self-care may be enough to allow the tear to heal. You should use crutches to protect the injured ligament.

Afterward, you will learn exercises to make the muscles, ligaments, and tendons around your knee stronger and more flexible.

  • You may need to work with a physical therapist to regain knee and leg strength.
  • Slowly, you can return to normal activities and perhaps return to sports again. Ask your doctor.

When to Call the Doctor

Call your doctor if:

  • You have increased swelling or pain
  • Self-care does not seem to help
  • You lose feeling in your foot
  • Your foot and leg feels cold or changes color

If you have surgery, call the doctor if you have:

  • A fever of 100°F (38°C) or higher
  • Any drainage from the injection or incision site
  • Bleeding that will not stop
