Post operative management will depend upon the Unit, but below will give you some idea.
Use crutches for 1 to 2 days or until you can walk nearly normally.
Elevate your leg so that your ankle is higher than your knee and your knee is higher than your hip.
Put ice on your knee for 20 to 30 minutes 3 or 4 times a day until symptoms have gone.
Bend your knee when symptoms have decreased.
Change your bandage after 4 days and cover the cuts with band-aids or gauze..
If the cartilage is repaired and not trimmed, the doctor may want you to use crutches longer and to not put weight on your leg.
Back to work will vary according to your type of work.....3 weeks____3 months.
