Knee injury treated with a splint

After the knee has been injured, a splint is placed on the leg to restrict movement and support it. Rehabilitation should start right away.

About your visit

We have examined you and have ascertained that you have injured your knee. We have placed a splint on your knee to restrict movement and support your leg. We have adjusted the splint to fit you. Do not readjust the splint without consulting your general practitioner.

You may: 

☐ remove the splint when washing

☐ remove the splint when sleeping

☐ not take off the splint

☐ put weight on the leg

☐ not put weight on the leg

If you need crutches, we have lent you a pair to take home with you.

When you get home

Move your foot, toes and hips

Bend at your hip and wiggle your foot and toes several times a day while wearing the splint. This increases blood circulation and reduces the risk of stiff joints.

Take pain-relieving medicine if you are in pain

You should take pain-relieving medicine if you are in pain. Pain-relieving medicine can be bought over the counter. Take only the amount of pain reliever recommended on the package. Contact your general practitioner if you need help managing the pain.  

Treat the injury using POLICE

Use the POLICE principle to ease and limit the extent of the injury. Continue the POLICE principle until the swelling has disappeared and for at least two days.

  • P = Protection: Protect the injured area. You may need to use an elastic bandage or athletic tape for a period of time.
  • OL = Optimal Loading: Loading the damaged tissue promotes healing. You may therefore put weight on your leg and move your knee if doing so does not worsen your pain.
  • I = Ice: Apply ice to the knee three to five times a day for 20-30 minutes. Wrap a bag of ice in a tea towel, for example, to avoid direct contact with your skin.
  • C = Compression: Use an elastic bandage except when sleeping.
  • E = Elevation: Elevate your leg when seated or lying down.

Remove and put on the splint correctly

If you are allowed to remove the splint, loosen all straps.

When it is time to put the splint on again, sit on a chair, bed or sofa with your leg straight. Open all the straps and stretch out the padding.

Place the splint under your leg, so the two hinges are level with the upper part of your kneecap. Wrap the padding around your leg.

Fasten the straps. Begin with the strap closest to your knee, then move up and down your leg.

It is best to wear the splint under your clothes. The splint should fit snuggly around your leg but should be loose enough for you to fit a finger under the strap. Use the clasps to open and close the splint and adjust the straps as the swelling goes down. Do not readjust the settings of the splint. Contact your general practitioner or dial 1813 to reach the medical helpline outside your general practitioner’s opening hours if you feel that the splint does not fit correctly.


You will be called in for a check-up to make sure your knee is healing correctly. We will also discuss further treatment at the check-up. You are very welcome to bring a relative.  We will call you about the time and place or notify you digitally or by mail.

If your condition deteriorates before your check-up, do not wait, but contact your general practitioner. If your condition deteriorates acutely, dial 1813 to reach the medical helpline.


Begin rehabilitation immediately

Start doing the exercises while you are wearing the splint. The exercises will help you regain strength and mobility in your knee.

If your knee begins to hurt while doing the exercises, take a 30 minute break and then continue doing the exercises. You may remove the splint when exercising.

How to do the exercises

Complete the exercises several times a day and repeat each exercise three to five times.

Exercise 1

Sit on the floor, a sofa or a bed with your injured leg straight. Place a thin cushion under your knee.

Press your knee into the cushion until you feel your thigh muscle tighten. Keep the muscle tightened for three to five seconds, and then relax your leg.

Exercise 2

Do the exercise with or without a cushion under your knee.

Lift your heel two centimetres until you feel your thigh muscle tighten. Keep the muscle tightened for three to five seconds, and then relax your leg.

Exercise 3

Stand on your injured leg and lift your other leg to the side and feel how the thigh muscle tightens in the injured leg. Keep the muscle tightened for three to five seconds, and then relax your leg.

Worth knowing

Throw away the splint when you no longer need it

The splint cannot be re-used. So, when you are done using it, throw it out.

Return the crutches after use

When you no longer need the crutches, please return them to us or to the hospital where you got them from.
