Официальное название
A Prospective Randomized Controlled Trial Comparing Constrained Condylar vs Posterior Stabilized Articulations in Revision Total Knee Arthroplasty
Обзор
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.
Подробное описание
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.

Критерии участия
Критерии включения
- 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, component malalignment, arthrofibrosis, patellar maltracking, reimplantation following single or two-stage exchange revision for prosthetic joint infection or bearing surface wear when femoral or tibial component revision is indicated.
- The use of revision total knee arthroplasty systems which have PS and CCK bearing options including different degree options of coronal and rotational constraint (to be individually randomized per constrained option):
- Zimmer Biomet Persona, NexGen, or Vanguard
- Smith and Nephew Legion
- DJO / Enovis Empowr
- Stryker Triathlon
- Link SymphoKnee
- Depuy Attune sion Criteria:
Критерии исключения

Patients undergoing rTKA for bearing exchange only rTKA, isolated tibial component rTKA
Patients with pre-operative diagnosis of extensor mechanism disruption or collateral ligament incompetence or with a compromised soft tissue envelope requiring pre-pre-operative plastic surgery evaluation and planned soft tissue coverage.
