New trends and early clinical outcomes with a modern knee revision system.

The incidence of revision total knee arthroplasty (TKA) has grown tremendously the past decade, and all projections suggest that it will continue to increase during the next 25 years. Although primary TKA remains one of the most successful orthopedic procedures, revision TKA has not as well. Failure rates for revision TKA remain significantly higher than those for primary TKA. New revision systems should be developed with new implants and instrumentation to address the difficulties frequently experienced with revision TKA. In this article, design surgeons report on the development of a new system and the early clinical experience with its use. The researchers believe that this new system is easy to use and facilitates accurate implantation, which could improve revision TKA outcomes.
