[Development and clinical application of ankle prosthesis].

Objective: To review the development and clinical application of ankle prosthesis.

Methods: The recent literature on ankle prosthesis design and clinical application was reviewed and analyzed.

Results: Compared with the hip and knee prostheses, the ankle prosthesis develops slowly and has been developed to the third generation. The ankle joint has a special structure of multi-axis movement. The design of the first and second generations of prostheses is not conformed to the biomechanics of the ankle. The third generation of prosthesis is more conform to the characteristics of ankle biomechanics, with high postoperative survival rate and satisfactory clinical outcome.

Conclusion: At present, the survival rate of ankle prosthesis is low, and there is still much room for improvement in biomechanics, materials, and other aspects.
