What is Knee Replacement Surgery?

Knee replacement surgery replaces a knee joint’s damaged surfaces with an artificial implant made of biocompatible metal and plastic. It’s a common treatment for severe “wear and tear” knee arthritis, rheumatoid arthritis, or advanced degeneration from previous injuries.


Benefits of Knee Replacement Surgery:

  • Relieves knee pain and discomfort
  • Improves knee flexibility and range of motion
  • Increases knee stability and corrects deformity
  • These advantages allow for pain relief, increased mobility and better quality of living
  • Long lasting results: Provides long-term durability, improving knee function for up to 20 years or more

According to a 2020 study published in The Journal of Bone and Joint Surgery, delaying knee replacement surgery can have a significant negative impact on your knee health and lessen the potential benefits received after surgery.

Signs You Need to Undergo Knee Replacement Surgery

If you’re experiencing the following symptoms, seek medical attention from an orthopaedic specialist. Early diagnosis and treatment can prevent additional harm and enhance treatment outcomes.

Frequent and severe knee pain

You may need a knee replacement if you often experience severe pain in your knees, especially if it impedes daily activities and sleep.

Chronic inflammation

Inflamed knees happen when the cartilage around your knees wears out and start to feel swollen, tender, and warm to the touch.

Decreased mobility

Some patients report having stiff joints and the inability to bend or straighten their legs, which can affect regular daily activities.

Knee deformity

Knee deformities such as swelling or having “bowed” knees may indicate joint damage that needs to be addressed via surgery.


If walking feels unstable and there’s a constant feeling your knee is “giving way”, it may be a sign that knee replacement surgery is necessary.

Am I A Candidate for
Knee Replacement Surgery?

If you experience severe knee pain, stiffness, deformity or instability when walking, you may be a candidate for knee replacement surgery. Here are other factors orthopaedic specialists consider when evaluating patients for the procedure:

Severity of pain: If your knee pain is severe and impacts your quality of life, your doctor may suggest knee replacement surgery as an option.
Level of activity: If you’re unable to participate in activities you enjoy (such as hiking, playing sports or even taking walks) due to knee pain, knee replacement surgery may be considered.
Lack of improvement with other treatments: Knee replacement surgery may be the next step if physical therapy, medication, and lifestyle changes bring no relief.

Is a Knee Replacement a Major Operation?

Yes, knee replacement surgery in Singapore is considered a major operation. It involves removing the damaged portion of the knee joint and replacing it with an artificial joint. The procedure usually requires general anaesthesia or spinal anesthesia, and patients typically stay in the hospital for a few days to recover.

Enhanced Recovery after Surgery

With enhanced recovery surgical techniques and protocols, patients are usually discharged after 1-2 days and started on an enhanced recovery program. Dr Wang Lushun specialises in ERAS (enhance recovery after surgery) techniques and has won awards for delivering superior outcomes in knee replacement surgery.

When Is The Best Time To Have Knee Replacement Surgery?

Do not let knee pain stop you from active living, it is recommended to have knee replacement surgery when the pain and decreased mobility have become severe enough to interfere with daily activities and when non-surgical treatments are no longer effective.


Consult with a qualified orthopaedic surgeon to discuss your individual circumstances and determine the best timing for the procedure.

    Frequently Asked Questions

    How Long Does It Take To Recover From a Knee Replacement Surgery?

    Recovery time after knee replacement surgery depends on the individual patient and their overall health status before the procedure. Generally, it takes around 6-12 weeks or longer to recover. During this time, patients will need to attend physical therapy and follow a personalized rehabilitation plan to help regain mobility and strength in the affected knee.

    What are the risks and complications associated with knee replacement surgery?

    As with any surgery, knee replacement surgery does carry some risks and potential complications, such as infection, blood clots, nerve damage, and implant failure. However, these risks can be minimized through careful preoperative planning, skilled surgical techniques, and appropriate postoperative care. Your orthopedic surgeon can discuss these risks and complications with you in more detail.

    How long does a knee replacement surgery take?

    The duration of a knee replacement surgery can vary, but it typically takes around 1-2 hours. Factors that can affect the length of the procedure include the severity of the knee damage, the patient’s overall health status, and the specific surgical technique used by the orthopedic surgeon.

    Can I still participate in sports or other physical activities after knee replacement surgery?

    Most patients can resume normal physical activities after knee replacement surgery, although full recovery may take several months. High-impact activities such as running and jumping may not be recommended, as they can put excessive strain on the artificial joint and increase the risk of damage.

    How long does a knee replacement last?

    The lifespan of a knee replacement can vary depending on factors such as the patient’s age, activity level, and the type of implant used. However, on average, a knee replacement can last for up to 20 years or more with proper care and maintenance.

    Can I drive after knee replacement surgery?

    Patients are usually advised to avoid driving for several weeks after knee replacement surgery, as it can be difficult to operate a vehicle while recovering from the procedure. Follow the advice of your orthopedic surgeon and physical therapist regarding when it’s safe to resume driving.
