Total Ankle Replacement
A third generation mobile bearing total ankle replacement (TAR), Zenith™ is based on a proven bearing surface geometry with a 25 year heritage(1). With advanced coating technologies and innovative instrumentation, Zenith™ represents the next generation in total ankle replacement.
Corin is dedicated to the use of advanced technologies to improve implant function and longevity.
| Titanium nitride (TiN) coating|
A ceramic layer applied to the polished surface designed to reduce wear and enhance longevity of the implant, TiN coating has been shown to reduce wear by up to 98%(2).
| BONIT® coating|
An established and proven process of applying a thin layer of calcium phosphate to a titanium plasma-sprayed layer, BONIT® is designed to provide optimal bone integration(3,4,5,6,7,8).
The third generation instrumentation allows the surgeon to carry out accurate, reproducible implant positioning with a comprehensive, fully jigged system. The option to make the tibial and talar cut on one jig is unique to this system.
The tibial stem has demonstrated stability with over 25 years of clinical use. Two anterior pegs on the talus provide primary and rotational stability along with even load transfer.
