A Prospective Randomized Controlled Trial Comparing Constrained Condylar vs Posterior Stabilized Articulations in Revision Total Knee Arthroplasty
Rush University Medical Center
Summary
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.
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.

Inclusion criteria: * Patients between 18-80 years of age * Patients who are undergoing both femoral and tibial component revisions, or isolated femoral component revisions with a retained tibial component that is compatible with PS or CCK bearings * Patients who are at least 6-weeks out from primary TKA surgery, with complete pre-operative and post-operative knee radiographs obtained at standard of care perioperative visits (AP/lateral and patellar views) * Patients undergoing rTKA for indications including aseptic component loosening, flexion or extension coronal or sagittal instability, co…
