In vivo three-dimensional determination of kinematics for subjects with a normal knee or a unicompartmental or total knee replacement. Total knee replacement (TKR) can broadly be of two types, posterior cruciate ligament (PCL) retaining and PCL substituting (or posterior stabilized). Good long-term data exist both radiographically and clinically for PCL sparing and PCL substituting types of implants. In total knee replacement surgery, the posterior cruciate ligament can be kept in place or removed. However, a number of studies have shown that PCL-retaining implants pro-vide … 7,20 Some surgeons routinely sacrifice the PCL, and others routinely spare the PCL. There are two principle designs of the PFC, a posterior cruciate sacrificing (PS) and an cruciate retaining (CR) PFC knee. The posterior cruciate ligament provides support and stable movement of the knee. Bicruciate-retaining total knee arthroplasty compared to cruciate-sacrificing TKA: what are the advantages and disadvantages? 4 Even if all the ligaments are healthy, it may be advantageous to sacrifice the cruciate ligaments and substitute their function through features of an implant. Our e-learning platform contains high resolution images and a certified CME of the Total knee replacement: PFC replacement (De Puy-Synthes) surgical procedure.

Most total knee arthroplasty (TKA) techniques involve sacrificing the anterior cruciate ligament or both cruciate ligaments. Patients’ dissatisfaction is still relevant (literature reports dissatisfaction rates as high as 40%). The effect of posterior tibial slope on range of motion after total knee arthroplasty. offset on knee flexion after cruciate-sacrificing mobile-bearing total knee replacement: a prospective analysis of 410 consecutive cases. This approach was originally introduced to increase the amount of exposure Albeit, the subject of Posterior cruciate sacrificing (PS) Vs Posterior cruciate retaining (CR) is debatable since the time of its inception, many studies prove the superiority of Posterior cruciate sacrificing knees. Knee replacement kinematics is a balance between letting the knee ligaments dictate the knee motion versus allowing the knee implant to force the knee motion to do what the surgeon thinks is best. Chapter 111 Posterior Cruciate Ligament–Substituting Total Knee Arthroplasty Michael P. Nett, Gregory J. Roehrig, Giles R. Scuderi, W. Norman Scott Posterior cruciate substitution in total knee arthroplasty gathered momentum and popularity as the pioneering surgeons and design teams improved on their prototypes. Knee included bearing dislocation, bearing breakage and an increase in polyethylene wear. When talking about cruciate-retaining TKA, usually it is the pre-servation of the posterior cruciate ligament (PCL). In total knee replacement surgery, a surgeon removes the damaged joint surface and replaces it with a metal and plastic implant. J Bone Joint Surg Am, 83 … Prior to proprioception testing, all subjects underwent clinical evaluation with completion of The Knee Society rating score. The anterior cruciate ligament is usually removed while performing a total knee arthroplasty, thus changing knee … 6. PCL is generally intact in osteoarthritic knees and if retained it helps in rollback of femur during knee flexion [ 1 , 2 ]. Even after total knee replacement surgery with successful results for 6 to 13 years, the hamstring to quadriceps ratios of the patients were still higher than those of the healthy subjects, and the cut or retained posterior cruciate ligament during total knee replacement surgery would not influence the relative muscle strengths. cruciate sacrificing knee systems in patients who underwent total knee replacement with both prostheses in opposite knees Brian W. Carey1* and James Harty2 Abstract Background: The ATTUNE Knee by DePuy Synthes was introduced in 2013. and spine. Posterior femoral rollback, less than in normal knees, routinely was observed in posterior cruciate substituting total knee arthroplasty, attributed to engagement of the femoral component cam with the tibial post” [ 13 ]. Total Knee Replacement (TKR) A total knee replacement (TKR) or total knee arthroplasty is a surgery that resurfaces an arthritic knee joint with an artificial metal or plastic replacement parts called the ‘prostheses'. Background —The decision whether to retain or resect the posterior cruciate ligament in total knee arthroplasty is at present determined clinically by preoperative radiological variables focusing upon the amount of joint destruction, and subsequent soft tissue contractures. It is designed to provide better range of motion and address patient-reported instability. Influence of Posterior Condylar Offset on Knee Flexion After Cruciate-Sacrificing Mobile-Bearing Total Knee Replacement: A Prospective Analysis of 410 Consecutive Cases Knee . [ 3 – 5] This system isdesigned for use in patients in primary total knee replacementsurgery, where the cruciate ligaments and the collateralligaments remain intact. Knee. Baumann F(1). Abstract: Total knee replacement (TKR) is a procedure used to treat knee arthropathy. [ 1, 2] Few TKA systems allow for the preservation of both cruciate ligaments. The debate over the relative merits of substituting or retaining the posterior cruciate ligament (PCL) in total knee arthroplasty is still ongoing. 2010 Dec;17(6):375-80. doi: 10.1016/j.knee.2009.11.001.

A subset of surgeons utilize a cruciate sacrificing (CS) procedure in which the PCL is released but is not replaced by a cam and spine. It is a posterior cruciate ligament retaining knee replacement system. In addition, total knee replacement surgery generates net societal savings of approximately $19,000* per patient lifetime due to reduced disability costs and improved productivity. Total Knee Arthroplasty is generally an effective procedure and is associated with substantial functional improvement. Usually, full knee replacements involve sacrificing the Anterior Cruciate Ligament (ACL) and then optionally sacrificing the Posterior Cruciate Ligament (PCL). Patients were excluded if they had a flexion contracture greater than 15°, a varus deformity greater than 20°, or a valgus deformity greater than 15°. Numerous retrospective studies of cruciate-retaining (CR) total knee arthroplasties have demonstrated consistently good clinical results and excellent intermediate and long-term survival.
