Journey II Bi-Cruciate Stabilized (BCS) Total Knee System Retrospective Study

The objective of this study is to estimate the safety and performance of Journey II BCS TKS.
Specifically, the study will establish revision rate, treatment- and device-related
complications, and clinical outcomes in a large sample of subjects who received the study
device. Subjects are screened consecutively, beginning at the earliest date of implantation
at each investigative site. Further, reasons for revision will be collected and analyzed. An
analysis will be performed to identify characteristics (patient, surgeon and surgical)
associated with an increased risk for revision. Finally, clinical, functional and quality of
life outcomes will be analyzed to the extent data is available, given the retrospective study
design.
