The Rebalance Total Ankle Replacement is a new 3 component uncemented mobile bearing prosthesis with a surface coating of ‘bonemaster’ and an ‘e’ poly bearing. The prosthesis was released in a limited way in May 2011. Since then 220 replacements have been implanted in 218 patients in 6 centres in 4 different countries (UK, Sweden, Canada, Czech Republic). All the x-rays and case notes were reviewed.63 prostheses have a minimum follow up of 2 years. Outcome measures included revision of the prosthesis, and the incidence of progressive and non-progesssive radiolucent lines around the prosthesis.
