BOX® Total Ankle Replacement

The BOX® Total Ankle Replacement stands apart from other contemporary devices. Its design is based on original research into the movement and stability of healthy ankle joints and the role of the ligaments in controlling and limiting joint movement.

The unique bearing geometry restores a more normal pattern of movement in the ankle with large rotations in all axes, where other devices limit motion. The BOX® Ankle works without imposing an unnatural fixed flexion axis, thereby allowing an excellent range of motion and better function.

  • The BOX® Ankle has been in clinical use since 2003 and is demonstrated to achieve good survivorship [1,2] and improvements in functional scores, patient satisfaction, range of motion and gait [1,3-6].
  • Enabling physiological coupled rotations in all degrees of freedom relieves neighbouring joints from the degenerative effects associated with loss of mobility.
  • Combining all key principles for long-term stable fixation with full congruency throughout ROM for stability and low wear[1,6-8], the BOX® Ankle sets a new benchmark for success of TAR.

 

    Natural movement without compromise
