A Study to Evaluate the DePuy Minimally Invasive Unicompartmental Knee
A Prospective, Non-Comparative Multi-centre Study to Evaluate the Safety and Performance of the DePuy Minimally Invasive (Preservation) Unicompartmental Knee and Instrumentation.
The primary purpose of this investigation is to evaluate the surgical performance of the DePuy Minimally Invasive (Preservation) Unicompartmental Knee and Instrumentation in a Multi-centre setting.
The secondary objective of this investigation is to evaluate the long-term survivorship of the DePuy Minimally Invasive (Preservation) Unicompartmental Knee.
