10 Myths and Facts about Knee Replacement Surgery

Knee replacement surgery is a surgery that consists of replacing a damaged or diseased knee joint with an artificial joint. Knee replacement surgery can help you get rid of a lot of discomfort and regain your lost abilities. It has a very high success rate. 

Despite the fact that knee replacement surgery is a very beneficial treatment option, many people have misunderstandings about it which discourage them from undergoing it.

Here are some myths and facts about knee replacement surgery. 

Myth #1: I should postpone the knee replacement surgery for as long as possible.

Fact: Wrong answer! Many people tend to avoid surgery and go for medications to cure knee pain. But medicines, especially painkillers, provide only symptomatic relief and that too just for a limited time. Also, long-term use of medicines can cause significant adverse effects such as renal failure, peptic ulcers, and other complications.

Postponing the surgery unnecessarily can make the surgeon’s job more difficult, which can also increase the risk of surgery-related problems.

Myth #2: The success rate of knee replacement surgery is quite low.

Fact: Knee replacement surgery is one of the most recommended treatments for damaged knees. People who get this procedure are able to go about their everyday lives pain-free and comfortably in quite less time. Knee replacement surgery has around 95 per cent success rate in most patients.

Myth #3: I will not be able to bend my knees properly after the surgery.

Fact: This is not at all true. Following surgery, you will be able to turn your knees with ease. Knee replacement surgery does not affect the movement of the joints and you will have no problem moving your legs.

Myth #4: Therapies such as acupressure, laser therapy, magnetic therapy and braces can help me get rid of my severe arthritis and knee pain.

Fact: Until now, there hasn’t been a scientifically proven permanent non-surgical treatment for severe knee arthritis.  All of these treatments may give short-term relief in early to moderate arthritis, but they do not provide a permanent cure. These methods may delay surgery for a while, but they cannot avoid surgery in severe cases.

Myth #5: There is no way to fix the implant if the knee replacement surgery fails or if a problem occurs after it.

Fact: If the first surgery somehow fails, a second surgery can be performed. After examining the causes of the failure of the initial operation and taking into account your general health, your doctor may conduct a second procedure, known as a revision surgery.

Myth #6: Knee replacement surgery is not for children

Fact: It is not necessary to be an adult to get knee replacement surgery. You can get it at an earlier age too if it is necessary. Knee replacement should be done right away whenever needed because it can become more difficult for the surgeon to perform the surgery if the patient waits, whether it is a child or an adult.

Myth #7: I will have to deal with a lot of negative consequences after getting a foreign metal into my body.

Fact: That is not true. The prosthetic joints are made up of a special metal that is compatible with our bodies and can stay in form without causing any side effects.

Myth #8: I should not get knee replacement surgery because I am too old.

Fact: Elderly individuals who are clinically fit can have knee replacement surgery anytime. Even at a very old age, patients who get knee replacement surgery can live a comfortable life with ease and relaxation.

Myth #9: Knee replacement surgery is good only for around ten years.

Fact: This is undoubtedly a myth. Times have changed. Today due to the high quality of knee replacement surgery and the utilisation of sophisticated methods throughout the procedure, knee replacement lasts for a lifetime. 

Myth #10: Knee replacement surgery is a very painful procedure and it continues even after the surgery is over.

Fact: Modern-day pain management guarantees that the patient is pain-free throughout surgery along with the post-surgical period and recovers quickly.

How Long Does It Take To Recover From Knee Replacement?

Knee replacement is a procedure by which components of the knee joint are replaced with artificial (prosthetic) parts. Knee replacement is useful to relieve severe pain caused by arthritis, cure knee deformity, restore activity, etc. 

Recovery and rehabilitation are important stages after knee replacement surgery.  It is therefore important to know how long will it take for you to recover from knee replacement. 

How Long Does It Take to Recover from a Knee Replacement Surgery?

Because each patient reacts to surgeries differently, knee replacement recovery durations may vary. Conditions such as the complexity of the surgery, the patient’s genetics and his/her overall health impact how fast the patient recovers from a knee replacement. 

After knee replacement surgery, patients are usually discharged from the hospital between 5 to 14 days. If the doctor allows, some people may go home the same day of the knee replacement as well. Within twelve weeks of surgery, most patients can start to walk with minimum or no assistance and only require over-the-counter pain medications. Most patients can return to their regular activities within three to six months.

After the knee replacement surgery, patients are urged to walk with the help of a walker, cane or other orthopaedic equipment. 

Physiotherapy after Knee Replacement Surgery

After discharge, physiotherapy is often given to the patient and this begins within a week after the surgery. The patient is often asked to do knee strengthening exercises, knee exercises to help with range of motion and scar tissue reduction and to use a walker or cane as an assisted walking aid.

The patient will ultimately be able to walk unassisted after gradually increasing strength and flexibility.

Knee Replacement Recovery Timeline

Within 6 weeks, most patients are able to care for themselves and they are able to resume their normal daily activities within 3 to 6 weeks. It might take anywhere from 4 months to a year to fully heal and get the full advantages of knee replacement surgery.

When can you start driving?

Most doctors allow patients to drive once they stop using pain medications and can operate the car painlessly and with ease, which is generally 2 to 4 weeks after the surgery. However if you are on narcotic pain medicines, you should not drive even after 4 weeks as they may hamper your concentration.

When can you get back to your work?

Joining back your work depends on your overall health, degree of physical activity and job expectations. Regardless of this, most patients can return to work after six weeks of surgery. If you have more physically demanding work, it might take up to three months.

How long does a knee replacement last?

With the advancements in the medical field, most knee replacements today last a lifetime. Going by the research studies, about 90% of first-time knee replacements last at least 15 years on an average, with many lasting even longer.  Patients who follow their physical therapy regimes and avoid high-impact activities can sustain their knee replacement for a lifetime. 

If the components of the first knee replacement need to be changed for any reason, a revision knee replacement may be required. The most typical reasons for revision surgery are component wear and tear, component loosening, infection, knee joint instability, knee stiffness and bone fractures.

Patients should discuss the ideal time to get the revision knee replacement surgery with their doctors.

After you’ve recovered from knee replacement, you can do low-impact activities like walking, swimming, golfing, or biking with ease. High impact activities such as running, skiing, tennis, and strenuous activities should be avoided. Make sure to discuss your restrictions with your doctor after knee replacement surgery.

Adjusting to Life after a Knee Replacement Surgery

In this article, we’ll go through some of the things you can expect after knee replacement surgery and what you can do to remain in the best health.

As you recover from knee replacement surgery, you may face some problems for which you should be prepared.  The recovery period can last anywhere from 6 to 12 months, and in different circumstances, it can be even longer.

You should be able to bend your knee sufficiently by four weeks following surgery. However, if you are using any medicines that may impair your ability to drive, you should not drive even after four weeks.

Going to Work

It will most likely take some time for you to return to your usual job schedule, but once you do, you must return cautiously to avoid injuring yourself during the time of your recovery. 

Therefore, you should plan on taking some time off work if you are getting knee replacement surgery and do not rush into things while you heal.

Once you’ve started to feel better, ask for work from home. Don’t force yourself to work before you are ready if yours is a physically demanding job.


As part of their rehabilitation, many patients opt to participate in physiotherapy. Small exercises prescribed by your physiotherapist might help you heal faster. However, you should wait until your doctor has cleared you to resume your normal fitness programme.

Follow your doctor’s exercise recommendations strictly. It’s a good idea to walk around or perform some moderate exercise once you’ve begun to feel better, but don’t rush into things to jeopardise your recovery.

Travelling, especially if you have to take a lengthy journey, can be difficult on the body following knee replacement surgery. However, you should be able to travel three to four weeks after your operation. 

Before embarking on any long-distance journey, remember to see your doctor. Also, stay prepared for airport security if you are travelling by flight. It is likely to be difficult and can cause delay because the metal detectors may detect the metal pieces in your artificial knee.

Consider waiting to travel by any means until your knee has completely recovered to keep your new knee in the best health.

Sexual Activity

Following knee replacement surgery, most people are able to resume sexual activities within a few weeks. If you are not in any discomfort and are comfortable moving your body, you may proceed. However, it is suggested that you only begin after consulting with your doctor.

Household Work

As soon as you feel comfortable in standing or walking around freely, you may resume your household work. But expect to wait for several weeks before you can totally resume all your daily activities.


Wear loose and light clothes that allow you to move easily following knee replacement surgery. In the winters, dress as comfortably as possible while also ensuring that you have enough layers to be warm. 

When going out in the sun, remember to use sunscreen and wear clothing that will shield your knee from direct sunlight.

Other Surgeries

You are at a high risk of infection for at least two years following knee replacement surgery. As a result, you may need to take antibiotics before undergoing any invasive surgical treatment or dental procedures. Therefore, consult your doctor before undergoing any such treatment.


Knee replacement surgery might be an excellent choice for you! However, like with any procedure, knowing what to anticipate throughout the recovery process can help you get back to your regular life as fast and painlessly as possible.
