The mobility total ankle replacement: techniques and pitfalls

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Total ankle replacement (TAR) aims to restore function and alleviate pain in patients with end-stage ankle arthritis.
• The Mobility total ankle replacement is an uncemented, mobile-bearing prosthesis designed for improved patient outcomes.

Purpose of the Study:

• To review the design rationale behind the Mobility total ankle replacement.
• To provide a comprehensive guide to the surgical technique for implanting the Mobility total ankle replacement.
• To offer practical insights and potential challenges encountered during surgery based on experience and literature.

Main Methods:

• Literature review of existing studies and clinical data on the Mobility total ankle replacement.
• Analysis of the implant's design features, including its 3-component structure and mobile-bearing mechanism.
• Description of the surgical procedure, emphasizing key steps and technical considerations.

Main Results:

• The Mobility implant features an uncemented, 3-component, mobile-bearing design.
• The tibial component is characterized by a flat articular surface and a conical intramedullary stem.
• The design aims to facilitate biological fixation and allow for component motion.

Conclusions:

• The Mobility total ankle replacement offers a specific design approach for uncemented arthroplasty.
• Understanding the design rationale and surgical technique is crucial for successful implantation.
• Awareness of potential technical tips and pitfalls can optimize patient outcomes.
