A new three-part total ankle prosthesis was designed  to achieve maximal compatibility between component relative motion and ligament natural role. This results in ankle natural mobility while maintaining full conformity, achieved by a backward and forward motion of the meniscus within the flexion arc. In this study the expected early functional recovery was evaluated by a clinical scoring system and by gait analysis.
The novel ankle prosthesis seems to contribute to an early functional recovery at 6 months maintained at one year. Preliminary assessments at 24 months confirmed the improvements achieved at 12 months. With reduction of pain and recovery of joint control, gait variables of high clinical interest, such as stance balance and ability in propulsion, improve considerably.
