4. Prone hangs
While laying flat on your stomach and your legs hanging off the edge of the bed, position the leg so that the kneecap is comfortably just off the edge of the bed. Simply relax your body and your legs so that your knee straightens out and stretches the back of your knee. Hold in this position for 5 minutes or as long as tolerated if less than 5 minutes.
5. Sitting knee flexion
While sitting in a chair, use the non-surgical leg to support the surgical leg, and slowly allow the surgical leg to go down to 90 degrees of flexion to the legs of the chair, hold with the knee bent for 5 seconds, then use the non-surgical leg to lift up and straighten the surgical leg all the way back to straight-leg position.
