Journey II BCS CMS Total Knee System Compared to Other PS Total Knee Systems in PT Setting

A Non-Randomized, Prospective Study of Short Term Outcomes Following Total Knee Replacement With JOURNEY™ II BCS Total Knee System Compared to Other Posterior Stabilized Total Knee Systems in a Physical Therapy Setting

The primary objective of the study is to determine how the short-term outcome of subjects implanted with the JOURNEY™ II BCS Total Knee System compares to subjects implanted with other PS total knee systems, and to determine if there is a difference in health care resources consumed that may result in economic savings to patients, the facility and/or the payer.

To address the study objectives, patient self-assessment questionnaires, and other objective measures of post-operative function and health care resource utilization will be used for data collection.
