Conformis is dedicated to advancing understanding of our products and their benefits to patients, surgeons, and hospitals through knee replacement clinical studies.
As a company, we are continuing to support head-to-head, direct comparative studies against many implant designs, and we are supporting multiple studies in progress that are assessing various patient outcomes measures.
You can find the latest information on clinical studies on Conformis implants on ClinicalTrials.gov.
