    Knee Replacement Surgery is where the diseased joint will be replaced by an artificial joint, which is called prosthesis. Knee Replacement Surgery relieves knee pain. The success rate of knee replacement surgery is approximately more than 95%.

    Knee replacement surgery is the best option to treat knee pain. However, there are some risks and benefits of the surgery. Our doctors at Medicover Hospitals want to clear all the misconceptions about this procedure. When the alternatives have started failing then people go for this treatment. Here is the updated list of myths with truths and real facts.

    Knee Replacement Myths:

    Myth 1: The success rate of knee replacement surgery is very low

    Fact 1: Many people have a misconception regarding the success rate after knee replacement surgery. The success rate after knee replacement surgery is 98%. However, the success rate of the surgery mainly depends on the few main parameters like performing the surgery successfully, post-surgery care, regular physiotherapy and following the diet prescribed by the surgeon and dietitian to avoid infections. In order to have this success rate, most of the patients have to do some physical exercises daily, the surgeon can let you know the type of exercises during the post-surgery consultation.

    People who have been suggested to take 6-8 weeks bed rest can do smaller activities. Exercises like straight leg exercises, knee bending exercises, buttocks squeeze, Prolonged Knee Stretch, hamstring sets can be done.

    Myth 2: Bending of the knee or sitting on the floor is difficult after replacing the knee

    Fact 2: Most of the patients think that it is impossible to move their knee after knee replacement surgery. The joints are attached to the prosthesis and this allows the artificial joint to move as the original joint moves. The same range of movements can be seen as the original joint moves.

    Using the computer navigation technique the angle to which the knee implant can be folded can be precisely set during the surgery (ideally 120 degrees). This solution helps the patient with a high success rate and patients can even bend their knee and sit down on the floor.

    Myth 3: If the surgery fails or a problem arises with the implant after the surgery, there is no chance to repair the situation again.

    Fact 3: If the surgery was failed initially it’s better to consult the best doctor in order to go for the second surgery. Based on the overall health and a detailed study of the patient’s medical history and evaluating the reasons for the surgery failure the second knee replacement surgery will be done by our surgeons. You can avail the second opinion on the revision of knee replacement surgery from Medicover Hospital surgeons.

    Myth 4: Knee replacement surgery does not last for more than 5-10 years

    Fact 4: As per theoretical records the knee joint replacement surgery would last for 15 years (average value). However, the durability of knee replacement surgery would depend on the type of implant used for surgery and post-surgery care.

    But the knee replacement surgery would practically last for 20+ years. Ideally, the durability of the knee surgery will increase up to 30+ years by using some special implants (surgeon will suggest and guide in choosing an implant for the surgery).

    We at Medicover Hospitals implement a computer navigation technique to perform knee replacement surgery which improves the accuracy of nearly 100% of the surgical outcomes. The angle of the newly placed implant can be adjusted to a precise level using computer navigation technique. As the computer used in the surgery navigates the surgeon during the surgery hence the failure rate will be very minimal and ideally can be considered to be zero.

    Myth 5: It takes few months time to recover from the surgery

    Fact 5: In fact, recovery time will be there for any surgery. In the case of knee replacement surgery, recovery time theoretically will be 14 days (2 weeks). But ideally, the recovery is directly proportional to the care taken post-surgery, infection rate, and the exercises post-surgery. Within a few weeks after the surgery, most of the patients recover. Following the prescribed diet and regular exercise will add an extra advantage to recover faster.

    Myth 6: Replacing both knees at the same time is not possible

    Fact 6: In fact, going for both knees replacement at a time will be advantageous for the patient. The patient can

    • spend less time in the hospital
    • save on leaves from work (for working people)
    • complete physiotherapy course for both knees at a time
    • have the extra benefit of reducing the procedure costs
    • free from surgical pain at the same time and recovery will be fast

    It’s better to take the doctor’s consultation while opting for the knee replacement for both the legs at the same time.

    Myth 7: Medication will suffice to avoid knee replacement surgery

    Fact 7: Medication will be prescribed for temporary relief from pain, but that cannot last long. In fact, using medication can lead to side effects like renal failure, peptic ulceration, and many other side effects.

    Opting for the surgery will relieve knee pain. Consulting an orthopedic surgeon may suggest you much better by performing some medical investigations like X-ray, MRI scan, etc.

    Myth 8: Knee replacement surgery is not successful after 60 years

    Fact 8: Knee replacement surgery can be performed for patients who are aged above 60 years also. In fact, we performed total knee replacement surgery for patients who are 90 years. Knee replacement surgery for old age people because that is the age when the cartilage in the knee joint gets damaged. 

    Knee replacement surgery is only suggested when an individual is unable to perform physical activities because of knee pain. Even patients who are aged 45 years are also suggested for knee replacement surgery because the patient is suffering from unbearable knee pain.

    Fact 11: There are so many alternatives for avoiding knee pain, but none of them were backed up with strong scientific research. Hence all the alternative methods will not last for a long period.

    These treatments may provide temporary relief and will not cure the disease. One can delay the surgery using the temporary treatments but ultimately surgery will give relief from the knee pain.

    An orthopedic surgeon can suggest a much better treatment plan.

    Myth 12: Knee replacement surgery is very painful

    Fact 12: Considering any surgical procedure, the pain exists immediately after the surgery is done.

    In fact, every patient who is undergoing knee replacement surgery mandatorily has to go for an aesthetic health screening called the surgical profile. The surgical profile consists of several tests like Echocardiography, Thallium Stress Echocardiography. The doctor will suggest treating heart ailments first before going for knee replacement surgery. Knee replacement surgery will be planned at a later date to avoid any mishappenings.

    Myth 16: In knee replacement surgery, the implant is rejected as a foreign body

    Fact 16: Knee replacement surgery is basically removing the infected knee and replacing it with the metal or ceramic implant which will work as the knee joint for the patient.

    Knee implant here refers to the foreign body. But, the knee implants are prepared with the materials which are compatible with the human body. Diabetes prevention will add extra benefits to avoid infection.
