Knee Replacement Surgery

Knee Replacement Surgery in Singapore

Knee replacement surgery, also known as knee arthroplasty, is a procedure where the damaged surfaces of the knee joint are replaced with metal and plastic implants. It is commonly recommended for individuals experiencing persistent pain and mobility issues due to conditions such as osteoarthritis, rheumatoid arthritis, or previous knee injury.

At Dr Chua Weiliang’s clinic, care is taken to ensure a clear diagnosis, careful surgical planning, and a supportive recovery process for each patient. Every treatment plan is personalised, considering the patient’s lifestyle, level of activity, and health status.

What Is Knee Replacement Surgery?

The term “knee replacement” can be misleading — the procedure is more accurately described as knee resurfacing. Only the damaged cartilage and bone surfaces are removed, and replaced with a smooth, durable metal and plastic implant that restores knee alignment and function.

Types of Knee Replacement

Total Knee Replacement

Involves replacing all three compartments of the knee — the femur (thighbone), tibia (shinbone), and patella (kneecap). It is recommended for extensive arthritis or deformity affecting multiple areas of the knee.

Partial Knee Replacement

Only the damaged portion of the knee is replaced. This may be suitable for patients with isolated arthritis, usually on the inner side (medial compartment) of the knee, and with good joint alignment.

When Should Knee Replacement Be Considered?

A knee replacement may be discussed with your doctor if:

Persistent pain limits your ability to walk, climb stairs, or carry out daily tasks
The knee joint feels stiff, unstable, or visibly misaligned (e.g. bow-legged or knock-kneed)
There is difficulty standing from a seated position or moving without assistance
Imaging (e.g. X-rays or MRI) shows significant loss of cartilage or structural deformity

Each case is assessed on an individual basis, taking into account your symptoms, lifestyle, and how the condition is affecting your everyday life.

Diagnosis and Pre-Surgical Planning

A comprehensive evaluation will be performed to ensure that knee replacement is the right choice for you. This typically includes:

A clinical examination to assess your knee’s range of motion, alignment, swelling, and stability
Imaging studies, such as X-rays or MRI scans, to evaluate the degree of joint damage
A review of your overall health status, medical history, and any existing conditions that may affect surgical safety or recovery

We understand that choosing surgery is a significant decision. Our goal is to provide clear information, address your questions, and guide you through each step, ensuring that any decision you make is made with confidence, clarity, and care.

What To Expect During A Knee Replacement Surgery

Knee replacement surgery is a carefully planned procedure designed to relieve pain and restore joint function. Understanding each step can help you feel more prepared and confident going into surgery.

Step 1: Anaesthesia

You will receive either spinal or general anaesthesia to ensure comfort throughout the procedure.

Step 2: Preparing the Knee

The surgeon makes a precise incision to access the joint and gently moves surrounding tissues aside.

Step 3: Removing Damaged Surfaces

Worn cartilage and bone from the thighbone, shinbone, and kneecap are carefully trimmed and removed.

Step 4: Placing the Implants

Metal and plastic components are inserted to recreate smooth joint surfaces and restore alignment.

Step 5: Closing the Incision

The incision is closed with sutures, and a sterile dressing is applied.

Step 6: Recovery Room Monitoring

You’ll be monitored closely as you wake up from anaesthesia before being transferred to the ward.

Recovery After Knee Replacement: What to Expect

Understanding what to expect after knee replacement surgery can help patients feel more confident and prepared for the recovery journey. While individual experiences vary, the process generally follows a structured path supported by physiotherapy, follow-up care, and self-motivation.

In-Hospital Recovery

Most patients stay in the hospital for 2 to 3 days after surgery. The care team will monitor your recovery closely and help you begin walking with assistance, usually within 24 hours after the procedure.

At-Home Recovery

After discharge, recovery continues at home with ongoing support from your physiotherapist. During this phase:

Swelling, bruising, and mild discomfort are expected in the first 1–2 weeks
Regular exercises and guided physiotherapy are essential to improve knee flexibility and strength
Sticking to a structured rehabilitation plan will help reduce stiffness and support healing

A successful recovery often depends on patient motivation, consistency in physiotherapy, and realistic expectations.

Full Recovery Timeline

Most patients experience significant improvement in pain levels and mobility by 3 to 6 months post-surgery. Progress is gradual, but steady effort consistently yields positive outcomes.

Potential Benefits of Knee Replacement

For those living with long-term knee pain, knee replacement can bring meaningful relief and help restore confidence in movement and daily life. Many patients find:

Lasting pain relief that makes everyday activities more manageable
Improved mobility for walking, standing, and enjoying routine tasks
A better quality of life with greater comfort and independence

Every recovery is unique. We’re here to support you at each step, with care that’s thoughtful, personalised, and focused on what matters most to you.

Potential Risks and Considerations

While knee replacement surgery has helped many individuals regain mobility and relief from pain, it is important to acknowledge that, like any surgical procedure, it carries certain risks.

Potential risks may include:

Infection
Blood clots (Deep Vein Thrombosis)
Stiffness or reduced range of motion
Implant loosening or wear over time

We understand that choosing surgery is a significant decision. Our goal is to help patients make informed choices through honest discussions, clear information, and personalised recommendations — always with your comfort, recovery, and long-term well-being in mind.
