If you’re researching knee replacement surgery Singapore as an option to relieve chronic knee pain, regain mobility, or restore quality of life, this article is for you. In Singapore, knee replacement is a well-established and technologically advanced procedure, offering hope to many who suffer from severe osteoarthritis and other joint conditions. In this article, we explain key aspects of the procedure, eligibility, cost, surgical techniques, recovery, risks, and how to choose a surgeon or hospital.
What Is Knee Replacement Surgery?
Knee replacement surgery—also known as knee arthroplasty—is a surgical intervention in which damaged portions of the knee joint are removed and replaced with artificial components (prostheses). These implants generally consist of metal alloys, medical-grade plastics, and sometimes ceramics. The goal is to restore joint alignment, reduce pain, and allow smoother movement.
There are two main variants:
-
Total Knee Replacement (TKR): The entire knee joint (femur, tibia, and sometimes the undersurface of the patella) is resurfaced and replaced.
-
Partial (Unicompartmental) Knee Replacement (PKR): Only one compartment of the knee that is damaged is replaced, preserving healthy parts of the joint.
In Singapore, both forms are widely practiced depending on the patient’s condition and surgeon’s assessment.
Who Is a Candidate?
Common Indications
People typically consider knee replacement when:
-
Severe osteoarthritis has caused cartilage loss, bone-on-bone contact, pain, stiffness, and functional limitations
-
Conservative therapies (e.g. medications, injections, physiotherapy) no longer provide sufficient relief
-
Pain affects daily life: walking, climbing stairs, standing, or sleeping
-
Knee deformity (bowing, knock-knee) is present
-
The patient is generally in stable health and can tolerate surgery
Contraindications & Considerations
Some conditions may make the surgery more complex or less ideal:
-
Active infection in or around the knee joint
-
Poor skin or soft tissue condition
-
Severe osteoporosis or bone loss
-
Certain neuromuscular or vascular disorders
-
Obesity beyond surgeon thresholds
-
Patients with unrealistic expectations
A surgeon will assess medical history, imaging (X-rays, CT or MRI), bone quality, alignment, and overall health before recommending the procedure.
Why Consider Getting It in Singapore
Singapore is well known for high standards in healthcare, strong regulatory oversight, modern hospitals, and highly trained orthopedic surgeons. Some advantages include:
-
Advanced Technology & Precision: Many centers in Singapore use computer navigation, robotic-assisted systems (e.g. MAKOplasty), and 3D-printed patient-specific instruments to enhance accuracy and longevity of the implant.
-
Comprehensive Pre- and Post-operative Care: From preoperative assessments to rehabilitation, hospitals in Singapore often coordinate multidisciplinary care.
-
High Safety & Quality Standards: Singapore’s hospitals maintain rigorous infection control, accreditation, and surgical quality metrics.
-
Medical Tourism Capability: Singapore is a recognized hub for medical travellers — good infrastructure, accessibility, and language support.
Thus, choosing to undergo knee replacement surgery in Singapore can help balance quality, safety, and outcome expectations.
Pre-Operative Preparation
Medical Assessments & Clearances
About 2–3 weeks before surgery, you’ll typically undergo:
-
Blood tests, ECG, chest X-ray
-
Anesthesia consultation
-
Medical review of existing conditions (diabetes, hypertension, cardiac status)
-
Imaging for joint planning
-
Preoperative physiotherapy education
-
Financial counselling and hospital admission planning
Lifestyle Adjustments
-
Quit smoking, control blood sugar, optimize nutrition
-
Stop or adjust certain medications (e.g. blood thinners) as advised
-
Strengthen muscles around the knee via supervised exercises
-
Arrange home support for early recovery
Hygiene & Fasting
-
Use antiseptic wash the night before surgery
-
Adhere to fasting instructions (no food or drink except plain water up to the cutoff)
These steps reduce risks and boost readiness for surgical recovery.
Surgical Techniques & What to Expect
Anesthesia & Incision
The surgery typically uses general anesthesia or regional (spinal) anesthesia, sometimes with sedation. The surgeon makes an incision (often 10–15 cm) over the knee to access the joint. Traditional approaches remain common, but minimally invasive or robotic-assisted techniques are increasingly used.
Bone Preparation & Implant Placement
Damaged cartilage and bone are removed, and the remaining bone surfaces are shaped precisely to accommodate the prosthetic components. Using guidance systems, the surgeon aligns and positions implants carefully to replicate joint mechanics and alignment. The prostheses are then fixed (cemented or press-fit) and soft tissues balanced.
Robotic or computer-assisted systems help reduce human error and improve precision, especially in alignment and component fit.
Closure & Wound Care
Once all components are in place, the wound is closed in layers and dressings are applied. Some centers use drains and compression dressings to control bleeding and swelling.
Surgery time may vary, often ranging from 1 to 3 hours, depending on complexity.
Cost & Hospital Stay
Typical Cost Ranges
In Singapore, private hospital costs for knee replacement can range widely. Some reports suggest USD 13,000 to 25,000 (or SGD 19,000–32,000 equivalent) depending on hospital, implant type, surgical technique, and hospital stay. In public hospitals, costs may be somewhat lower.
These costs usually cover:
-
Hospital bed and nursing
-
Operating theatre and consumables
-
Implant components
-
Surgeon & anesthetist fees
-
Medication, physiotherapy, imaging
Hospital Stay & Immediate Recovery
Most patients stay in hospital for 3 to 5 days (or more if complications). Early mobilization begins within a day after surgery, guided by physiotherapists. Crutches or walking aids are commonly used in the early phase.
Follow-up visits happen weekly initially, then monthly or quarterly as recovery progresses.
Recovery & Rehabilitation
Early Phase (First 0–6 Weeks)
-
Pain control through medications and ice therapy
-
Physical therapy: range-of-motion, isometric strengthening, gait training
-
Wound monitoring and dressing changes
-
Use of mobility aids as needed
-
Prevent blood clots with anticoagulants and leg exercises
Intermediate Phase (6–12 Weeks)
-
Gradually increase weight-bearing, walking distances
-
Progressive strengthening and functional exercises
-
Work on balance, stability, and daily activity training
Long-Term Phase (3–12+ Months)
-
Return to light sports (if approved)
-
Continued muscle conditioning
-
Monitoring for implant integrity, alignment, or complications
Most patients experience substantial pain relief and improved mobility by 3 to 6 months, with further gains for up to a year.
Benefits & Expected Outcomes
-
Significant reduction or elimination of knee pain
-
Restored alignment and stability
-
Improved mobility for walking, stairs, daily tasks
-
Better quality of life, independence
-
Long-lasting implants (many lasting 15–20 years or more)
Even partial knee replacement can achieve excellent functional results when selected appropriately.
Risks, Complications & How to Mitigate
Potential Risks
-
Infection
-
Deep vein thrombosis (DVT) or pulmonary embolism
-
Nerve or blood vessel injury

Persistent swelling or numbness
Mitigation Strategies
-
Strict sterile protocols in hospital
-
Use of prophylactic anticoagulants
-
Early mobilization and physiotherapy
-
Preoperative optimization (control of comorbidities)
-
Close follow-up and early detection of issues
Understanding risks and working with experienced surgical teams helps minimize complications.
