You will learn leg exercises during physical therapy (PT) to help you recover from an ACL injury. You will need to exercise several parts of your leg to build strength and flexibility evenly. If you work one area too much, you may injure your knee because the opposite side will be weaker. Your PT provider will tell you which exercises to do. He or she will also tell you how often to do them. You may start by doing the exercises with your provider and then continue to do them at home.
What safety precautions do I need to take?
Warm up before you do the exercises. Walk or ride a stationary bike for 5 or 10 minutes to warm your muscles.
Follow your PT provider's directions for activity. You will not be able to run or play sports right away. PT takes time. You will need to build your speed and endurance. Do not try to lift heavy weights or do weight-bearing activities before your provider says you are ready. You may cause more injury to your ACL.
Stop if you feel pain. Pain may be a sign that you are not ready to be doing a certain movement. You should expect some discomfort at first. Your leg may be stiff or sore. As you continue PT, it should become easier to do the exercises without discomfort. Always tell your provider if a movement causes pain.
