The unilateral stance will strengthen your stability. This exercise should only be done if you don't have any locking, clicking, or giving way in your injured knee.

• Stand in front of a counter or chair with your hands lightly resting on the counter/chair.
• Shift all of your weight to your injured leg, and stand only on the injured leg.
• Stand just on that leg for 30 to 60 seconds, then put the other foot down and rest. Repeat 8 to 12 times during the day.
• As long as there is no pain, you can make this exercise a little harder by slightly bending your injured knee and standing on just that leg. Hold 30 to 60 seconds. Repeat 5 times.
