3D Model Guided Ankle Replacement

There is a clearer market leader with ankle replacements, which is now the most commonly used ankle replacement in the UK and Australia with the lowest revision rate. Technology hasn’t evolved to do robotic ankle replacements as yet, so we use 3D models to make bone cutting jigs to guide how we place the ankle replacement.

Much like the MAKO, a 3D model is taken of your joint, and that model is used to guide implant positioning. The difference between this technology and the MAKO, is that instead of the robotic arm assisting with the cuts, intra-operative x-rays are used so everything lines up as planned on the preoperative 3D virtual model before any bone cuts are made. The aim with any joint replacement is accurate impact positioning with the aim of improving outcomes.

There is still a healthy debate regarding the risks and benefits of an ankle fusion versus an ankle replacement. Whilst there are pros and cons to each option, patents eligible for an ankle replacement must fit within certain guidelines to ensure we have a successful result, with age, BMI, and existing deformity playing a role.

There are 2 main types of ankle replacements seen in the video below, with a stemmed component being available for those with softer bone or with a larger preoperative deformity.

If you do have ankle arthritis and wish to consider an ankle replacement, please get in contact and we’ll be happy to discuss the options available.
