There were higher rates of re-revision in the latter group secondary to persistent infection and aseptic loosening

Constrained Condylar Total Knee Replacement

A constrained condylar knee design was developed to resist coronal moments in the plane caused by soft-tissue deficiency. Constrained condylar knee designs have the advantage of allowing changes in the center of rotation during flexion, and thereby, theoretically impart less tangential anterior-posterior stress across the prosthetic interface The LEGION Total Knee System is a comprehensive system designed to allow surgeons to address straightforward primary to complex revision knee arthroplasty. By virtue of its unique implant design features, proprietary materials and intuitive instrumentation, LEGION empowers surgeons to manage diverse surgical challenges and provide personalized joint care with one system, one company Background: Constrained condylar knee (CCK) prosthesis are common used for revision surgery but can also help surgeons to improve implant stability in primary knee arthroplasty, in fact in severe knee arthrosis with serious deformity associated with a significant instability a more constrained articulation is required. With introduction of second generation of semi-constrained prosthesis, rate. Allograft-prosthesis composite (APC) can restore capsular and ligamentous tissues of the knee sacrificed in a tumor extirpation. We asked if performing APC would restore knee stability and allow the use of nonconstrained arthroplasty while preventing aseptic loosening. We retrospectively compared 50 knee APCs performed with non-constrained revision knee prosthesis (Group 1) with 36 matched.

Femur first—Reduce the valgus degree of resection to 3°; the entry point for IM rod in a valgus knee is usually more medial than in a standard knee. Ascertain the point with preoperative radiographs

Legacy constrained condylar knee (CCK) prostheses are readily available to assemble and use with a CCK articular surface or a posterior stabilized (PS) articular surface in revision knee arthroplasty surgeries. We wanted to validate outcomes of revision total knee arthroplasty (TKA) using legacy CCK prostheses combined with a PS articular surface BACKGROUND Different levels of constraint for total knee arthroplasty can be considered for revision surgeries. While prior studies have assessed the clinical impact and patient outcomes of condylar constrained knee (CCK) and rotating hinged (RTH) implants, nowadays little is known about the biomechanical effects induced by different levels of constraint on bone stress and implant micromotions

Issack and colleagues 5 described 2 cases of fracture through the taper lock between the femoral component and the stem extension in the Optetrak stemmed-constrained condylar knee prosthesis (Exactech). Westrich and colleagues 6 reported disengagement of the locking bolt of the Insall-Burstein II Constrained Condylar Knee (Zimmer) leading to. Conclusions. The need of constraint is relatively infrequent in primary versus revision total knee arthroplasty. Indications include deficient collateral ligaments, inadequate soft tissue balancing that cannot be salvaged, and marked metaphyseal bone loss (i.e, supracondylar femur or proximal tibia)

Varus-Valgus Constrained Knee. Varus-valgus constrained implants have a tall tibial post and a deep femoral box, providing inherent stability in the coronal plane. The influence of tibial-patellofemoral location on function of the knee in patients with the posterior stabilized condylar knee prosthesis INTRODUCTION. In total knee arthroplasty (TKA) severe coronal plane instability of the knee is difficult to balance with a cruciate-retaining (CR) or a posterior-stabilized (PS) implant [].In such conditions, a 'constrained condylar knee' (CCK) implant is preferred [].CCK implants are, in fact, characterized by a large and tall tibial intercondylar eminence, which fits closely into a deep. The increasing number of revision knee arthroplasty result in the more frequently use of a constraint implant but results from previous reports are difficult to interpret. The purpose of this study was to compare the long-term outcomes of superficial cemented versus metaphyseal cemented in revision total knee arthroplasty with a condylar constrained arthroplasty
