Before the Treatment

Before bilateral knee replacement surgery, the knee replacement surgeon may conduct a serious of diagnostic tests to check for your overall fitness. These generally include an ECG, blood tests, and a chest X-ray.

You may also be advised to perform a few exercises to strengthen the muscles of your knee and legs. This helps ensure faster and easy recovery. You are advised to talk to your surgeon and a few of his patients to set expectations out of the procedure. You should be aware of the approximate knee replacement recovery time and the amount of pain that you are likely to experience.

You will be told not to eat or drink anything at least six to 12 hours before the surgery. If needed, your surgeon will conduct an arthroscopic examination of your knee to see the extent of damage and device a surgical approach that best suits your condition.

How it is Performed

  • Surgical Process of Knee Replacement:

    A bilateral knee replacement surgery is sometimes performed on both the knees in a single surgery or the surgeon may decide to operate on them individually in separate surgeries. The former case is preferred when the patient is young and the overall health is normal and maintained. In the latter case, there could be a gap of a few hours or a few days between the two surgeries.

  • Anaesthesia Administration:

    During bilateral knee replacement surgery, you will be given general or spinal anesthesia to make you unconscious or induce numbness. The knee is cut open (in case of open surgery) and a small incision is made in case of minimally invasive surgery.

  • Type of Knee Implants

    The surgeon removes the kneecap and then the damaged or diseased parts of the knee are removed. These are replaced with a metal, plastic, or ceramic implants (as chosen by the surgeon, depending on the requirement). The implants are fixed using cemented or cementless fixation. The incision is closed with the help of stitches.

  • Duration of the Surgery

    Bilateral knee replacement surgery lasts anywhere between one to three hours (is a single knee is replaced) or four to five hours (if both are replaced during the same surgery). Once the surgery is over, you are transferred to the recovery room for a few hours.


Bilateral knee replacement surgery is a major procedure and therefore, recovery may take time. You are likely to experience pain for the initial few weeks. However, it goes away gradually as you start performing physical exercises recommended by the doctor.

You should keep your wound dry and clean to prevent infection after the surgery. In addition, you should elevate your leg often for reduced pain. Talk to your surgeon if you experience redness, swelling, or inflammation around the knee.
