During knee replacement surgery, surgeons cut damaged bones and cartilage from your knee and replace it with an artificial joint. Knee replacements can help to alleviate pain and restore function to diseased knee joints, according to MayoClinic.com. Knees are commonly replaced as a result of arthritis and failed conservative treatment. Regular exercise can help to restore mobility as well as strength in your new knee. Always consult your doctor before beginning exercises following a knee replacement.
Seated Knee Bends
Do sitting knee bends early in your recovery. According to the American Academy of Orthopaedic Surgeons, this exercise can be completed as you sit on a chair or on the side of your bed. Cross your new knee over your good leg to add support as you exercise. Your legs should be extended. Slowly bend your knee toward the chair or bed. Bend only as far as you are comfortable with going. Hold this position for 10 seconds. Straighten your legs out again and repeat for one set of 10 repetitions. Complete this exercise throughout the day. You may be able to completely bend your knee as you progress.
Ankle Pumps
Complete this exercise while seated in bed. Fully extend your legs with your toes pointing toward the ceiling. Move your foot up and down by contracting your calf and shin muscles. Try to complete this exercise for a few minutes straight a few times each hour. This may help to subside the swelling in your lower leg and ankle.
Walking
Walking is one of the best ways to help your new knee recover, according to the American Academy of Orthopaedic Surgeons. Stand straight up using your walker or crutches, and proceed forward with your recovering leg. The heel of your foot should touch the floor first. As you continue walking, you knee and ankle will bend and the ball of your foot will rest on the floor. While learning to walk after surgery, always remember to touch your heel to the floor first. Try to walk across a room at first and progress from there. Your doctor will tell you when you are allowed to begin weight-bearing exercises.
Cycling
Using an indoor exercise or stationary bike can help you to regain strength in your leg muscles and increase the range of motion in your knee, according to the American Academy of Orthopaedic Surgeons. Wait to do any cycling until you doctor gives you the OK. Sit on the bike and adjust the seat so that your feet touch the pedals and your knees are nearly straight. Start by pedaling backwards. Once you are comfortable, pedal forwards. Complete this exercise for 10 to 15 minutes initially and progress to a daily exercise session of 20 to 30 minutes. Progress as you begin to build endurance and experience little pain or discomfort.
