Ankle Replacements are effective at pain relief, and preserve the range of motion of the ankle joint. As a result, it reduces the subsequent stresses upon the adjacent joints in the foot and the knee and decreases the risk of developing arthritis in those joints compared to fusion.
Ankle replacement results in a more natural gait pattern and walking pattern on inclines and stairs and as a result research has shown high satisfaction rates in outcome scores. It is well studied in the Australian Joint Registry which monitors all total ankles put in in Australia.
In general 85% of patient’s prosthesis are successful at the 10 year mark. Using data from previous prostheses, Patients over 65 have a 13% risk of failure after 10 years, and patients aged 55-65 up to 18%. Ankle replacement is suited to patients ideally over 65 with range of motion of the ankle and particularly for patients with arthritis in the surrounding joints.
Before surgery a CT scan is performed to prepare the customised Patient Specific Jigs. An engineered plan is then used to create the ideal mechanical alignment, and specific anatomical details are incorporated. The jigs are made and sent to the hospital. This process takes 6 weeks.
