Product catalog summary

Overview: The BOX® Total Ankle Replacement is designed to provide reliable soft tissue tensioning and gap balancing, preserving bone stock, ensuring stability, and optimizing implant positioning for enhanced function. The approach allows for maximum visibility of the joint space, reducing the need for excessive checks.

Key Features:

Advanced instrumentation and ligament tensioning techniques ensure optimal tension in the soft tissue envelope with minimal bone resection.
Intuitive instrument layout enhances operating room efficiency and ease of use, with a reduced learning curve due to a fully jigged procedure.
Soft tissue balancing techniques validate component positioning, ensuring stability and maximizing range of motion (ROM).
Precise alignment and preparation instruments restore alignment, provide stable fixation, and protect tissues.

Design and Functionality:

The BOX® Total Ankle Replacement is based on research into healthy ankle joint movement and ligament roles, offering a more natural gait and function.
Unique bearing geometry restores normal movement patterns without imposing a fixed flexion axis, allowing for excellent ROM and function.
Allows physiological freedom of movement, including inversion/eversion, to relieve degenerative effects on neighboring joints.
Features a deep sulcus saddle-shaped talar bearing for maximum stability and natural IE rotation coupled with flexion.

Clinical Performance:

In clinical use since 2003, the BOX® Ankle shows significant improvement in functional scores and ROM, with high patient satisfaction.
Registry data reports a 2.5% reoperation rate, with most requiring only a meniscal component change.
Multicenter studies report over 97% survivorship at 3 years and 96% at 4 years, with no failures due to aseptic loosening.

Materials and Construction:

Anatomically profiled components based on radiographic data ensure low-profile resurfacing without excessive bone removal.
Enhanced cementless bone fixation with as-cast beaded fixation and HAP coating for long-term stability.
Proven materials and articulating couples ensure durability and low wear.

Conclusion: The BOX® Total Ankle Replacement combines key principles for long-term stable fixation, setting a new benchmark for TAR success with its innovative design and clinical efficacy.

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. A more natural gait and function The unique bearing geometry restores a more normal pattern of movement in the ankle with large coupled rotations. It works without imposing a non-physiological fixed flexion axis, resulting in an excellent range of motion and better function. Physiological freedom of movement for the normal...
