What does Posterior Stabilized Knee mean?
Posterior-stabilized implants attempt to replace the role of the PCL with a polyethylene post and femoral cam that interact to prevent anterior translation of the femur on the tibia, while allowing femoral rollback during flexion.
What is attune knee system?
The DePuy Attune knee system is a total knee replacement implant. DePuy also manufactures an Attune model for revision knee replacement surgery. DePuy designed the Attune knee to improve stability and motion. EXPAND. DePuy’s rotating platform design is intended to reduce stress and wear on the implant.
What is cruciate retaining knee replacement?
Using a cruciate retaining knee implant during a total knee replacement procedure allows for less disruption to the surrounding areas during surgery, a more natural movement after surgery, and allows patients to maintain the full stability of the joint after surgery.
What is a CCK knee replacement?
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.
How long do attune knee replacements last?
High Risk of Early Failure for Attune Knees These artificial knees typically last 15 to 20 years in most patients.
Is the ACL removed in a total knee replacement?
Most of the knee replacement designs require the removal of the ACL, even if, as shown by our study, the majority of patients still have this ligament intact. The integrity of the ACL was also noted in different articles [9–11].
What is the difference between posterior and bicruciate stabilised total knee replacements?
Bicruciate-stabilised total knee replacements produce more normal sagittal plane kinematics than posterior-stabilised designs.Ward TR, Burns AW, Gillespie MJ, Scarvell JM, Smith PN J Bone Joint Surg Br. 2011 Jul;93 (7):907-13. 5. Catani F, Ensini A, Belvedere C, Feliciangeli A, Benedetti MG, Leardini A, Giannini S.
Does bi-cruciate retaining total knee arthroplasty restore native articular kinematics during gait?
Bi-Cruciate Retaining Total Knee Arthroplasty Does Not Restore Native Tibiofemoral Articular Contact Kinematics During Gait. J Orthop Res. 2019; 37 :1929–1937.
What is bicruciate-retaining knee arthroscopy?
Bicruciate-retaining (BCR) TKA was developed to mimic knee biomechanics, through anterior cruciate ligament preservation. First-generation BCR TKA has not gained popularity due to its being a challenging technique and having poor survival outcomes.
Are there limitations to bicruciate-retaining total knee arthroscopy (TKA)?
However, a considerable dissatisfaction rate has been reported by highly demanding patients due to the intrinsic limitations provided by the TKA. Bicruciate-retaining (BCR) TKA was developed to mimic knee biomechanics, through anterior cruciate ligament preservation.
