Post Market Clinical Follow Up of LEGION™ Primary TKS With VERILAST™

Status Active, not recruiting

Clinical Trial Summary

LEGION™ Primary Total Knee System is CE-marked and marketed in all study regions. This study serves as post-market surveillance for LEGION™ Primary Total Knee System with the VERILAST™ bearing surface (OXINIUM™ femoral component with highly cross-linked polyethylene tibial insert). All study subjects will receive a LEGION™ Primary Total Knee System with VERILAST™ bearing surface and the results will be analysed against historical data from patients who received a Genesis II knee replacement.

Clinical Trial Description

The LEGION™ Primary Total Knee System (TKS) is a comprehensive, state-of-the-art system that empowers surgeons to address diverse surgical challenges and provide personalized joint care. The LEGION™ Primary TKS implant designs were built on the legacy of the GENESIS™ II TKS. For more than 15 years and in more than 30 countries, the GENESIS™ II TKS has achieved outstanding clinical outcomes. As CE-mark and 510k approval for the LEGION™ Primary TKS has been obtained, it is being used in clinical practice in several countries including Europe and the US but clinical studies need to be carried out in order to confirm its safety and efficacy and in order to conform to the medical device directives (MEDDEV. 2.7.1 Rev.3). This study is therefore a post-market study to evaluate the short-, mid- and long-term safety and effectiveness of the LEGION™ Primary TKS with VERILAST™ bearing surface (the combination of an OXINIUM™ femoral component with highly cross-linked polyethylene tibial base plate inserts). The clinical outcome from a large cohort of subjects who are treated with the LEGION™ Primary TKS as part of their standard of care will be documented. The study is designed to reflect standard clinical practice as closely as possible because it allows the results of such a study to represent the true clinical outcome that would be achieved in clinical practice, up to a maximum. Only subjects who will be treated with the LEGION™ Primary TKS as part of their normally planned care will screened for participation in this study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
