About
This study aims to compare the clinical impact of Constrained Condylar versus Posterior Stabilized Knee (PS) bearings on patient satisfaction and surgical outcomes including mid-term survivorship among patients undergoing revision total knee arthroplasty.
Full description
The primary purpose of this study is to determine whether a difference exists in clinical patient reported outcomes between CCK or PS bearings following rTKA. A secondary goal of the study is to compare both bearings in survivorship free of revision surgery as well as other surgical complications including instability, in early to mid-term follow-up.
