Knee Replacement Surgery in Singapore
If you suffer from severe knee pain and limited mobility that affects your quality of life, knee replacement surgery in Singapore may be a solution to consider. This procedure involves replacing the damaged surfaces of your knee joint with artificial components, effectively relieving pain and restoring function.
With a high success rate of 95-98%, knee replacement surgery has helped countless individuals regain mobility and enjoy a more active lifestyle. Whether you require a total knee replacement or a partial knee replacement, this procedure can significantly improve your quality of life and allow you to participate in the activities you love.
What Is Knee Replacement Surgery?
Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure designed to relieve pain and restore function in a damaged knee joint. During the surgery, the damaged bone and cartilage surfaces are removed and replaced with artificial implants made of metal and plastic. These implants are designed to recreate the smooth surface of the joint, allowing for easier movement and reduced pain.
There are two main types of knee replacement surgery:
- Total Knee Replacement: This procedure involves replacing the entire knee joint, including the ends of the thighbone (femur), shinbone (tibia), and sometimes the kneecap (patella).
- Partial Knee Replacement: This less invasive option replaces only the damaged portion of the knee, preserving the remaining healthy bone and tissue.
Knee replacement surgery is typically recommended for individuals with:
- Advanced knee osteoarthritis: When the cartilage that cushions the joint wears down, causing severe pain, stiffness, and limited mobility.
- Chronic knee pain: When pain persists despite non-surgical treatments like medication, physiotherapy, and injections.
Who Needs Knee Replacement Surgery?
Before undergoing knee replacement surgery, careful preparation is essential to ensure a smooth procedure and optimal recovery. This involves pre-surgery evaluations and following specific instructions provided by your knee surgeon.
To ensure you’re fit for surgery, you’ll undergo a series of assessments, which may include:
- Blood tests: To assess your overall health and identify any potential issues.
- Chest X-ray: To evaluate your lung health.
- Electrocardiogram (ECG): To check your heart function.
These tests are typically conducted within one month before surgery at our clinic or the hospital.
Our surgeon will also provide detailed instructions to follow in the weeks leading up to your surgery. These may include:
- Medication Management: Guidance on which medications to continue or stop taking before surgery.
- Strengthening Exercises: Specific exercises to strengthen the muscles around your knee, which can aid in your recovery.
- Lifestyle Adjustments: Recommendations on diet, activity levels, and other lifestyle factors to optimise your health before surgery.
What to Expect During Surgery
On your knee replacement surgery day, you will be admitted to the hospital at least 2 hours before the scheduled procedure. This allows time for pre-operative preparation, such as reviewing your medical history and preparing the surgical site.
The actual knee surgery takes approximately 1.5 to 2 hours. However, you will be in the operating theatre for 3 to 4 hours to account for pre-operative preparation and post-operative monitoring.
During the surgery, you will be under anaesthesia, so you won’t feel any pain. Our skilled surgeons utilise advanced techniques and minimally invasive approaches whenever possible to minimise complications and promote faster recovery. These techniques may include:
Minimally Invasive Incisions:
Smaller incisions reduce tissue damage and scarring, leading to quicker healing.
Computer-Assisted Navigation:
This technology helps surgeons achieve precise implant placement, improving accuracy and outcomes.
Specialised Instruments:
The use of specialised instruments allows for less disruption to surrounding tissues, minimising trauma and promoting faster recovery.
Advanced Pain Management Techniques:
Our pain management techniques result in very satisfactory pain levels post-operation. In fact, the vast majority of our patients do not feel bothered by post-operation pain at all.
Robotic Surgery:
For certain cases, the option of using a Robotic arm to assist our surgeon is available. The benefits of a Robotic arm are that the bony cuts are made very precisely and the implants are implants very accurately to ensure longevity of the treatment.
After the surgery, you’ll be moved to a recovery area where you’ll be closely monitored as you wake up from the anaesthesia.

Knee Replacement Implants
In knee replacement surgery, the damaged parts of your knee joint are replaced with artificial components called implants. These implants are designed to mimic your knee’s natural shape and function, allowing for smooth movement and pain relief.
- The femoral component replaces the end of the thighbone (femur) and is usually made of cobalt chrome.
- The tibial component replaces the top of the shinbone (tibia) and can be made of titanium or cobalt chrome.
- A plastic insert made of polyethylene is placed between these components to create a smooth, gliding surface.
Knee replacement implants are designed to be long-lasting. In 85-90% of cases, the implants can last for 20 years or more. However, factors such as activity level, weight, and overall health can influence the lifespan of it.
Risks and Complications
While knee replacement surgery is generally safe and effective, it carries potential risks and complications like any surgical procedure. These may include:
Infection:
Infection can occur at the surgical site or around the implant.
Blood Clots:
Blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism) are a potential risk after any surgery.
Implant Loosening:
Over time, the implant may loosen or wear down, potentially requiring revision surgery.
Dislocation:
Although rare, the knee joint can dislocate after surgery, especially with certain activities like deep squatting.
Nerve or Blood Vessel Damage:
There’s a very small risk of damage to nerves or blood vessels around the knee during surgery.
To minimise these risks, our experienced surgeons utilise advanced surgical techniques, minimally invasive approaches, and personalised post-operative care. This includes:
Minimally Invasive Incisions:
Smaller incisions reduce the risk of infection and promote faster healing.
Careful Tissue Handling:
Surgeons take great care to protect surrounding tissues and minimise trauma during surgery.
Prophylactic Medications:
Medications may be prescribed to prevent blood clots and infection.
Early Mobilisation:
Getting you moving soon after surgery helps reduce the risk of complications like blood clots.
Personalised Rehabilitation:
A tailored rehabilitation programme helps you regain strength and mobility, reducing the risk of implant loosening and dislocation.
Recovery After Knee Replacement Surgery
Recovery from knee replacement surgery is a gradual process that involves regaining strength, mobility, and function in your knee.
Rehabilitation Timeline
- After surgery, you’ll use a walking frame for the first 2-3 weeks to support your knee while you regain strength and balance.
- You’ll then transition to a walking stick or quad stick for up to 1.5 months as your mobility improves.
- Full recovery typically takes 3-6 months, but this can vary depending on individual factors and the type of surgery.
Here are some recommendations for a smooth recovery
- For the first two weeks after surgery, keep your knee covered with a waterproof bandage and shower while seated to protect the incision.
- Minimise stair climbing and use assistance when necessary.
- If you require additional support at home, consider arranging for a caregiver or a short stay at a step-down care facility.

Frequently Asked Questions About Knee Replacement Surgery
How long does a knee replacement last?
Knee replacement implants are designed to be durable, and in 85-90% of cases, they can last for 20 years or more. However, factors like activity level, weight, and overall health can influence the lifespan of the implant.
How soon can I walk after surgery?
Most patients begin walking with the assistance of a walking frame the day after surgery. As your knee heals and strengthens, you’ll gradually transition to a walking stick and eventually independent walking.
What is the cost of knee replacement surgery in Singapore?
The cost of knee replacement surgery varies depending on several factors, including the type of surgery (total or partial), implant choice, hospital stay, and post-operative care. We offer transparent pricing and various options to make the procedure more affordable. Schedule a consultation with us to discuss your needs and get a personalised quote.
Can I squat after knee replacement?
While some patients may find they can squat after surgery, it’s generally not recommended. Squatting puts increased pressure on the implant, which can increase the risk of loosening or wear. Your surgeon will provide specific guidance on activities to avoid or modify after surgery.
What activities can I resume after surgery?
After you recover, you can generally resume most low-impact activities, such as walking, swimming, cycling, and golfing. However, high-impact activities like running, jumping, or contact sports may be discouraged to protect your new knee joint. Your surgeon and physiotherapist will provide personalised guidance on appropriate activities and exercise levels.
