Total Ankle Replacement Using Lateral Approach shows Good Long-term Outcomes

A new clinical study highlights the long-term success of a total ankle replacement using a unique lateral approach. Led by Dr.Lew C. Schon at Mercy Medical Center’s Institute of Foot and ankle Reconstruction, the research focuses on the Zimmer Biomet trabecular Metal Total Ankle Replacement.
Published in the Journal of Bone and Joint Surgery, the study tracked 130 patients for at least five years.The results demonstrated the implant’s exceptional durability and functionality. The total ankle replacement procedure showed no need for revision or removal of components during the study period, which ranged from five to 12 years.
The zimmer Biomet implant uses a transfibular surgical technique, differing from traditional anterior approaches. This lateral method, combined with the implant’s design and materials, contributes to its stability. the implant features a bone-sparing curved shape and utilizes highly cross-linked polyethylene and tantalum trabecular metal.
According to schon, the lateral approach allows for better alignment and restoration of the joint. The technique involves cutting the outer bone, which is often deformed, and positioning it correctly. The arthritic surfaces are then milled away.
The study also indicated that the Zimmer biomet total ankle performs well in both younger and older patients, including those under 55. This age group often experiences higher failure rates with other ankle replacement systems. While patients can resume many daily activities, high-impact exercises are discouraged to prolong the implant’s life.
The findings suggest that the Zimmer Biomet lateral approach ankle replacement system offers a durable and effective solution for end-stage ankle arthritis. The study showed limited periprosthetic radiolucency and no signs of implant subsidence or loosening during the follow-up period.
What’s next
Further research will continue to monitor the long-term performance of the Zimmer Biomet total ankle replacement and refine surgical techniques for optimal patient outcomes.
