ACL Rehabilitation: Knee Flexion

Begin your rehabilitation with exercises that develop muscle control. These help you meet basic goals, like driving a car or going back to work. Exercise as often as you're advised. But stop right away if any exercise causes sharp or increasing pain. Icing your knee for 15-20 minutes after exercise can help prevent swelling and soreness.

• Sit on the floor with your legs out and feet flexed forward. Place a towel around the heel of your injured leg.

• Pull the towel toward you, sliding your heel toward your buttocks. Keep the heel in contact with the floor.

• When you feel a stretch (tightness) in the knee, hold the position for 10 seconds. Slide your foot back out. Repeat 5 times.
