Advanced Exercises After Knee Replacement Surgery

Choose a preferred language

Advanced exercises help strengthen and stretch the muscles around your knee. Unless told otherwise, do each exercise 10 times per session. Build up to 25 repetitions. Do 2 sessions each day or as directed by your healthcare provider. Always contact your provider or physical therapist if you have pain during these exercises or as otherwise directed.

Make exercise part of your daily routine. Lack of exercise can cause joint stiffness and decreased range of motion. But with continued exercise, you may even gain more strength and range of motion than you had before surgery. Keep meeting with your physical therapist as directed. They may add riding a stationary bike or other new exercises to your program.


Short-arc knee extensions

  • Lie on your back. Place a rolled towel under your new knee and bend the other knee.

  • Keeping your new knee on the towel, lift your foot several inches (above your buttock) to straighten the knee.

  • Hold for 3 to 5 seconds. Slowly lower the foot.

Straight leg raises

  • Lie down on your bed or on a mat on the floor. Bend your good leg, keeping your foot flat on the bed or floor.

  • With your operated leg, tighten the front of the thigh (quadricep) to straighten the knee as much as possible. Lift it about 6 to 10 inches (above your buttock) off the bed or floor. At first, you may only be able to lift the leg a few inches.

  • Hold for 3 to 5 seconds. Slowly lower the leg.
