Ankle arthritis is a debilitating condition that can significantly impair a person’s mobility and overall quality of life. In Singapore, where an ageing population remains increasingly active, finding the right ankle arthritis treatment is essential for maintaining independence. While conservative measures are always the first line of defence, advanced surgical options such as Total Ankle Replacement (TAR) have become a viable solution for those suffering from end-stage joint degeneration.
In recent years, the lateral approach to total ankle replacement has gained prominence among orthopaedic specialists. This article explores the circumstances under which this surgery is required, its associated benefits and risks, and the estimated costs in Singapore.

When Is Lateral Total Ankle Replacement Surgery Needed?
Most cases of ankle arthritis in Singapore are “post-traumatic,” resulting from previous fractures or severe ligament injuries sustained during sports or National Service. When the protective cartilage in the ankle joint wears away, the resulting bone-on-bone friction causes chronic pain and stiffness.
A doctor may recommend lateral total ankle replacement surgery under the following circumstances:
- End-Stage Ankle Arthritis: When the joint damage is so severe that non-surgical treatments—such as physiotherapy, orthotics, or injections—no longer provide relief.
- Failed Conservative Management: Persistent pain that interferes with daily activities like walking, climbing stairs, or performing work duties.
- Desire For Joint Mobility: Unlike ankle fusion, which locks the joint in place, a replacement is ideal for patients who wish to preserve the natural “hinge” motion of the ankle.
- Good Bone Quality: The patient must have sufficient bone density to support the metal and plastic prosthetic components.
The lateral approach specifically involves an incision on the side of the ankle (the fibula side). This method allows the surgeon to access the joint while maintaining the integrity of the ligaments at the front of the ankle, often leading to a more stable result.
The Pros And Cons Of Lateral Total Ankle Replacement
Choosing between an ankle replacement and an ankle fusion (arthrodesis) is a significant decision. Understanding the advantages and disadvantages of the replacement option is crucial for any patient.
The Advantages (Pros)
- Preservation Of Mobility: The primary benefit of a replacement is that it allows the ankle to move up and down. This results in a more natural walking gait.
- Protection Of Adjacent Joints: Because the ankle can still move, less stress is placed on the surrounding joints in the foot and mid-foot. This reduces the long-term risk of developing arthritis in those neighbouring areas.
- Significant Pain Relief: Most patients experience a dramatic reduction in pain, allowing them to return to low-impact activities like cycling or swimming.
The Disadvantages (Cons)
- Component Wear: Like all artificial joints, the prosthetic components may wear out over time. A replacement typically lasts 10 to 15 years, after which a revision surgery may be necessary.
- Surgical Risks: As with any major procedure, there are risks of infection, blood clots, or nerve damage.
- Strict Activity Limits: Patients with an ankle replacement must avoid high-impact activities such as running or jumping to prevent the implant from loosening.
Benchmark Cost Of Ankle Replacement Surgery In Singapore
For many Singaporeans, the financial commitment is a vital factor in deciding on a surgical Ankle Arthritis Treatment. Costs can vary significantly between public and private healthcare institutions.
According to data from Health365 and Ministry of Health (MOH) fee benchmarks for 2026, the professional fees for a Primary Total Joint Replacement of the Ankle (TOSP Code: SB703A) are estimated as follows:
| Type Of Fee | Recommended Range (Private Sector) |
| Surgeon Fee | $12,200 – $15,600 (Excluding GST) |
| Anaesthetist Fee | Approximately 20% to 35% of the Surgeon Fee |
Important Note: These figures represent professional fees only. They do not include hospital ward charges, surgical consumables, medications, or the cost of the prosthetic implant itself, which can be substantial. Patients in public hospitals can expect significantly lower out-of-pocket costs due to government subsidies for eligible Singaporeans and Permanent Residents.

Frequently Asked Questions
Patients typically need to remain non-weight-bearing for approximately 2 to 6 weeks using crutches or a knee scooter to allow the bone to grow into the implant. Full recovery, including intensive physiotherapy to regain strength and balance, usually takes between 3 to 6 months.
Yes, Singaporeans and Permanent Residents can use their MediSave to offset a portion of the surgical and hospitalisation costs. The exact withdrawal limit depends on the complexity of the surgery as defined by the Table of Surgical Procedures (TOSP). It is advisable to consult the clinic’s billing department for a detailed financial breakdown.
There is no “one-size-fits-all” answer. An ankle replacement is often better for older patients who want to maintain movement and have lower physical demands. An ankle fusion is generally recommended for younger, highly active individuals or those with severe bone loss, as it provides a very durable and stable—albeit stiff—joint.
