This TKR guide is part of our patient-focused care to provide you a specific post-operative protocol that you should follow to restore strength and mobility to your knee and a gradual return to everyday activities which are important for your full recovery after knee replacement. You should already be familiar with some advice and exercises during your hospital stay. Should you have any questions on the exercise activities, please seek advice from your doctor or therapist.

General Information

  • Early post-operative exercises such as ankle pumps, knee presses, and bed-supported knee bends will help increase circulation to your legs and feet which is important for preventing blood clots in leg veins. These exercises do not only strengthen your muscles but also improve your knee movement.
  • To help decrease swelling and pain, you should apply cold compress to your operated knee for 10-15 minutes while lifting the leg on supporting pillows after leg exercising, stand upright, or walk.

Proper lying posture

  • Lie on your back: Elevate your leg while keeping your knee straight. Avoid pillow support under your knee.
  • Lie on your side: Lie on your normal side with pillow support in between the knees. Avoid lying on the side of the operated knee.

Getting into a car

  • Stand with your back facing the side of the car, legs touching the side of car seat. Gradually lower yourself onto the seat and slide towards its center. With knees close together, lift your legs up and at the same time swing your body and legs into the car.
  • Start with short walks spreading throughout the day and slowly increase your walking distance. A sudden increase in your walking activity may cause more swelling, stiffness, and pain. A proper gait aid will be given/advised during your recovery period at the hospital.
  • Pain medication should be taken as prescribed. It is important that your pain is controlled so that you can complete 2-3 exercise sessions each day and gradually increase your walking distance.
  • Other precautions: avoid deep squat, knee twist.
