Hold a counter or a sturdy chair. Take a big step forward with your operated leg, so one foot is well in front of the other. Keep your body upright. Bend both knees a short way, going straight down, then push back up. Keep the front knee over the middle of your foot. Do not go further than halfway down.
If an exercise hurts more than you expect, stop and contact your clinician.
