You can expect to have pain in your knee, your thigh, the inner and outer sides of your leg,and possibly your shin and your other leg.
Eventually as you're walking more, due to the way your structure was altered all at once in the OR, you might encounter hip, buttock, low back pain, or sciatica. These are all within normal and generally respond to home treatment.
Are you taking pain meds as ordered?
Are you icing and elevating "toes above nose" for 45 - 60 minutes at a time?
