Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study design is a prospective, multicenter, study of the commercially available Zimmer Trabecular Metal Ankle semiconstrained implants. The study will require each site to obtain Institutional Review Board approval prior to study enrollment. All potential study subjects will be required to participate in the Informed Consent Process.

All study subjects will undergo preoperative clinical evaluations prior to their primary or revision total ankle arthroplasty. The post-operative clinical and radiographic evaluations will be conducted at 6 weeks, 6 month, 1 year, 2, 3, 5, 7, and 10 years. Follow-up surveys will occur at 4, 6, 8, and 9 years.
