Fusion or Replacement of the Ankle Joint

Chronic ankle pain can be a life-altering issue, especially if it’s due to arthritis or injury. Whether it’s difficulty walking, standing for long periods, or simply discomfort with everyday activities, it’s important to know that you have options. Mark sees many patients in his Harrogate and Leeds clinics from all over Yorkshire and indeed the UK with severe ankle problems.  It’s important that following a welcoming discussion in the clinic and further diagnosis of the issues, both total ankle replacement and ankle fusion surgeries are understood and discussed. 

Both treatments have their merits, and while one isn’t necessarily better than the other, deciding which is best for you depends on your specific situation. Here are some of the key differences between these two procedures.

Total Ankle Replacement (TAR)?

Total ankle replacement is a surgical procedure where the damaged ankle joint is replaced with a prosthetic implant, mimicking the natural motion of your ankle. It’s usually recommended for patients with advanced ankle arthritis, where the cartilage has worn away, and the bones are rubbing together on either side of the joint, causing pain, swelling, and limiting movement.

The benefit of TAR is that it allows the patient to maintain a full range of ankle movement, which can be important for maintaining a natural gait. 

One advancement that’s improved the precision of this surgery is the Prophecy system, a patient-specific technology that uses preoperative CT scans to create 3D models of the ankle. This helps ensure the implant is placed as accurately as possible, improving overall alignment and potentially reducing recovery time. Think of it as a custom-fit solution for your ankle. Every anatomy is different, and Prophecy takes this into account every time. Mark has many years of experience with more traditional methods of TAR surgery, and now combines that experience with the Prophecy system to give his patients the very best TAR surgery possible. 

What Is Ankle Fusion?

Ankle fusion involves removing the worn-out joint surfaces and permanently joining the bones together. While this means losing the joint’s flexibility at the fusion site,  fusion provides long-term pain relief for patients with severely damaged or unstable joints.

The main advantage of ankle fusion is that it’s a reliable and durable solution, especially for patients with deformities or weakened bones, where maintaining joint movement might not be the best option. Once fused, the ankle won’t move at that point, but it will be stable and pain-free for the long haul, which can be especially important for individuals with significant joint damage or severe arthritis.

Which Is the Right Choice?

Choosing between total ankle replacement and ankle fusion isn’t a matter of one being better than the other; it’s about what’s right for you.

• If maintaining ankle motion is important to your daily life and you’re still relatively active, total ankle replacement might offer the best outcome. It’s a great option for those looking to preserve movement while still addressing pain and instability.
• On the other hand, if your ankle is severely deformed or you have lower bone quality, ankle fusion may be more appropriate. It eliminates pain and stabilises the joint, which can offer a better long-term solution for some patients.

This is a conversation Mark has with each patient to determine what’s best based on your specific anatomy, lifestyle, and the extent of the joint damage. Both procedures have a place in modern orthopaedics, and the goal is always to ensure the option chosen will give you the best quality of life moving forward.

What to Expect After Surgery

The recovery process will depend on which procedure you undergo. After total ankle replacement, patients usually start walking with support (crutches or a walker) within a few weeks, followed by physical therapy to restore strength and flexibility in the joint. The Prophecy system can help reduce recovery time in some cases, but as with any surgery, patience and following your post-op care plan are key.

With ankle fusion, recovery may be slightly longer, especially as the bones take time to heal and fully fuse together. You can expect to be off your feet for a period, but once the bones are fused, the pain relief is typically long-lasting, and the stability provided by fusion is excellent.

It’s About Finding What’s Best for You

In the end, whether you choose total ankle replacement or ankle fusion, the most important factor is finding the right solution for your needs. Both procedures can provide significant relief from pain and restore function, but they address different aspects of joint damage.
