Exercise bike
If you have access to an exercise bike, set the seat high so your foot can barely reach the pedal and complete a full revolution. Set the resistance to "light" and progress to "heavy". Start pedaling for 10 minutes a day. Increase the duration by one minute a day until you are pedaling 20 minutes a day.

Walking
An excellent physical exercise activity in the middle stages of your recovery from surgery (after 2 weeks).

Running should be avoided until 6-8 weeks because of the impact and shock forces transmitted to our knee. Both walking and running activities should be gradually phased into your exercise program.
