ROBODOC® Clinical Trials: Long-Term Follow-Up

This is a follow-up study looking at the and long-term results of two methods of preparing the thigh bone to receive an implant during hip replacement surgery. For one group of patients in the original study, the surgeon used a cutting tool called a broach and a special hammer on patients who had standard hip replacement operations. For the other patients, the surgeon used a surgical robot which was equipped with a cutting tool, like a drill, to prepare the thigh bone. The purpose of this study is to collect additional information confirming that the surgical robot is safe and effective when used as recommended. Only patients who were enrolled in the original clinical trials are eligible for this study.
