Position yourself so that you are on your stomach with your knees hanging just over the edge of the surface you are on (most commonly, a firm bed). Keep your affected knee down and place your other foot on top of the foot on your affected side to provide a gentle stretch to your knee. Hold for 3-5 seconds and repeat for 10 repetitions.
*Prone hangs may be difficult to perform. If too difficult you can substitute with Heel Prop Exercises.
