Total knee replacement is a common procedure that accounts for 300,000 surgeries for patients with end-stage arthritis, according to the National Institutes of Health. There is pain and tenderness in your knee after surgery, but knee exercises can help speed your recovery time.
Quantity
According to Allina Hospitals and Clinics, you should perform post-operation knee exercises starting with 10 sets of five repetitions. Add five repetitions weekly until you reach 20 repetitions or until your knee feels fatigued. Your exercise routine should take place two to three times per day for 20 to 30 minutes each time, according to the American Academy of Orthopaedic Surgeons. Performing the required quantity of knee exercises is uncomfortable at first, but they should become easier as you heal.
In Bed
Start with your legs straight. Place your foot flat on the bed and in a slow and controlled movement, slide your foot toward you so your affected knee bends toward the ceiling and your heel is moving close to your buttocks. Once your knee can't bend any further, hold the position for 10 seconds and then slowly slide your foot until your legs are straight. With your knees straight, tighten the thigh of your affected knee and lift it several inches off the bed. Hold the position for 10 seconds and continue to perform the exercise until your knee becomes fatigued, according to the American Academy of Orthpaedic Surgeons. Next, stretch your calf muscle so your toes point toward you and then change this position by pointing your toes away from you. Follow this exercise by rotating your ankles in both directions.
Sitting
Sitting in your chair, slowly lift your foot so your leg is straight in front of you. Keep your knee straight while holding the position for five to 10 seconds and then slowly bring your foot down. Your next exercise is simple: Keep your knee loose while you gently kick it back and forth in small motions.
Walking
According to the American Academy of Orthopaedic Surgeons, you should walk 30 minutes at least twice per day after a total knee replacement. During the first few weeks, use crutches or a walker to help you walk. Do not avoid placing pressure on your affected leg. Your surgeons will instruct you on how much weight you can put on the knee. Walk using controlled and smooth movements by placing your heel first, then flatten your foot and lift your toe, according to the American Academy Orthopaedic Surgeons.
