When in December makes a big difference. I would expect that it would be nearly impossible for the first 4 weeks post op. You'll still be on heavy duty pain meds and not sleeping well. I assume there are other drivers. When you are getting off narcotics during the day you'll be able to drive, but you'll still have some problems with leg swelling if you sit too long. You might be able to get away with it near the end of December but plan on
spending some time laying in the back seat with your legs up. Stop frequently and take some little walks.
