Here’s a list of exercises that are recommended to people who just undergo knee replacement surgery:
Straight Leg Lifts. Lie on your back with your legs fully extended. Lift your leg about six inches and hold for 10 seconds.
Ankle Pumps. While lying flat on your back, bend both ankles up and point your toes toward you. Then bend your ankles down and point your toes away from you.
Thigh Squeezes. Lie flat on your back and tighten the muscles in front of your thigh by pushing the back of your knee down toward the floor. Hold for five seconds and relax.
Knee Bending. Sit in a stable chair and bend your leg so that it is underneath the seat, bending your knee back as far as possible. Hold it for five seconds and then return it to the resting position.
I wish everything is well with you, enjoy!
