Introduction to Ankle Replacement Surgery in Singapore
The ankle is a small but very important joint made up of three bones: the tibia and fibula (the two bones in your lower leg) and the talus (a bone in your foot). These bones work together to help you walk, run, and turn.
Despite its compact size, the ankle can withstand forces of up to five times body weight during running or jumping. This high load, combined with a limited range of motion, makes the joint more vulnerable to injury. Over time, repeated sprains, fractures or untreated instability can accelerate joint degeneration and contribute to the development of ankle arthritis.
What Is Ankle Replacement Surgery?
Ankle replacement surgery may be considered when severe joint damage persists despite medications and physiotherapy. During the procedure, the damaged surfaces of the tibia and talus are removed and replaced with prosthetic components. These are designed to restore joint alignment, reduce pain and maintain movement.
The goal of ankle replacement is to allow more natural foot motion while reducing stress on neighbouring joints.
When Is Ankle Replacement Surgery Recommended?
Ankle replacement is typically reserved for individuals whose ankle joint has deteriorated to a point where conservative treatments no longer offer relief. These include people suffering from ankle conditions such as:
- Osteoarthritis
- Rheumatoid arthritis
- Post-traumatic arthritis
- Sports-related injuries
When Is Ankle Replacement Not Recommended?
Although ankle replacement surgery can benefit selected patients, it is not suitable for everyone. In certain situations, the risks may outweigh the potential benefits. Specialists may advise against ankle replacement in people with:
- Severe joint deformity, as proper alignment of the implant may not be achievable.
- Weak or fragile bones, which may not support the prosthetic components securely.
- Ongoing or recent infection, due to the risk of infection spreading to the implant.
- Poorly controlled diabetes, which can impair wound healing and increase the risk of complications.
- Advanced nerve damage, which may affect joint stability and increase the risk of injury after surgery.
A thorough assessment helps determine whether ankle replacement is appropriate or if alternative treatments should be considered.
What Happens Before Ankle Replacement Surgery?
Preparation helps optimise surgical outcomes and recovery. This usually includes a medical assessment, imaging studies and discussions about medications, activity levels and post-operative care. Patients may be advised to stop certain medications, arrange home support and plan for limited mobility during the early recovery period.
What Happens During Ankle Replacement Surgery?
Ankle replacement is performed under anaesthesia. The surgeon removes damaged joint surfaces and positions prosthetic components to restore alignment and movement. The procedure aims to relieve pain while preserving ankle motion and protecting surrounding joints.
What Happens After Ankle Replacement Surgery?
After surgery, the ankle is protected to allow healing. Pain control, wound care and gradual rehabilitation are key parts of recovery. Patients typically begin guided physiotherapy to restore strength and movement, with follow-up appointments to monitor healing and implant stability.
What Are the Risks of Ankle Replacement Surgery?
Every surgical procedure carries some degree of risk, but most patients undergo ankle replacement safely with careful planning and monitoring. Possible risks include:
- Infection: Even with sterile technique and antibiotics, there is a small risk of infection in the skin, deeper tissues or around the implant.
- Blood Clots: Clots can form in the leg after surgery.
- Implant Wear or Loosening: Over time, the metal and plastic parts can wear out or shift, especially in very active patients.
- Stiffness or Persistent Pain: Some patients may still have stiffness or pain due to scar tissue, nerve sensitivity or arthritis in nearby joints.
FAQs About Ankle Replacement Surgery
What are ankle replacement implants made of?
Most implants have metal components, usually titanium or cobalt-chromium alloys, paired with a high-grade plastic insert that acts as a shock-absorbing surface. These materials are chosen for durability and compatibility with the body.
Is ankle replacement painful?
Pain is common immediately after surgery, but it is carefully managed with medication and medical supervision. The long-term goal of the procedure is to significantly reduce chronic ankle pain.
What is the recovery time for an ankle replacement?
Recovery varies, but most patients regain most improvement by 6 months, with full recovery often taking 9 to 12 months. The timeline depends on individual healing speed, adherence to rehabilitation and whether there were complications.
How long will it take before I can walk after an ankle replacement?
Full walking without aids may take around 8 to 12 weeks, but balance and strength can continue to improve for months.
What physical limitations will I have after ankle replacement?
High-impact sports like running, basketball or competitive tennis are discouraged to protect the implant. Walking, swimming, cycling and golf are usually safe once fully healed.
How long do ankle replacement implants last?
Modern implants can last 10 years or more, with survival rates around 85 to 90% at the 10-year mark for suitable candidates. Lifespan depends on activity level, bone quality and surgical precision.
Can ankle replacement surgery be revised if needed?
Yes, in some cases a revision surgery can be performed if the implant wears out, loosens, or complications arise. However, revision procedures can be more complex than the initial surgery.
