Filter by:The LCS Complete Cementless Knee by DePuy Synthes is a rotating platform knee replacement with a good clinical track record and good survival rates. The cementless ATTUNE Cruciate Sacrificing (CS) Rotating Platform Knee by DePuy Synthes has been designed to provide better range of motion and address the unstable feeling some patients experience during everyday activities, such as stair descent and bending. It is expected that the cementless ATTUNE Rotating Platform Knee will have regulatory approval early 2016. Patient inclusion will start after regular approval has been obtained. The objective of this study is to accurately assess and compare migration, clinical and radiological outcome and patient reported outcomes (PROMS) of two TKR prostheses: the Cementless ATTUNE Rotating Platform Cruciate Sacrificing Knee System and the LCS Complete Cementless Cruciate Sacrificing Knee System (rotating platform design), both by DePuy Synthes, Warsaw, Indiana, USA. In this single-blind, randomized non-inferiority trial, 32 patients with the ATTUNE Knee System and 32 patients with LCS Knee System will be included. The study population will consist of patients with symptomatic osteoarthritis of the knee scheduled for TKR surgery at the Department of Orthopaedics, Spaarne Gasthuis, Hoofddorp, The Netherlands. Annually 300 TKA procedures are performed in this department, of which about 95% is Osteo Arthritis (OA). The investigator anticipates that inclusion can be accomplished within a 1 year period and that the total study duration is 3 years. Main study parameters/endpoints are: - Migration, measured by means of RSA. - Patient Reported Outcome Measures by means of questionnaires.
Evaluate the safety and effectiveness of patients who received G7 Acetabular system in conjunction with Ceramic on Ceramic articulation and Taperloc Complete Microplasty stem compared to patients who received the Exceed ABT Acetabular system with the same combination
The NexGen TKR (Zimmer, Warsaw, Indiana, USA) is a proven TKR design that has reported excellent medium and long-term results in clinical studies and in implant registries all around the world. As a follow-up of the NexGen TKR, an improved design has recently been introduced by Zimmer: The Persona TKR (Zimmer, Warsaw, Indiana, USA) has been used successfully in about 20.000 patients, but results from independent clinical studies have not been reported yet. The objective of this study is to accurately assess and compare migration, kinematics, prosthesis placement and patient reported outcomes of two TKR prostheses: the fixed bearing, cemented NexGen LPS, a proven design with an excellent clinical track record, and the fixed bearing, cemented Persona PS, a new design without clinical data (both designs by Zimmer, Warsaw, Indiana, USA). The primary objective is to assess and compare migration of the two TKR prostheses (Femoral and Tibial component). The secondary objective is to assess and compare clinical data, kinematics, prosthesis placement and patient reported outcome measures. This study is designed as a single-blind randomized trial between the Persona PS total knee prosthesis and the well-established NexGen total knee prosthesis. Different sample sizes are used for the different parts of this study: - 30 Patients with NexGen LPS prosthesis and 30 patients with Persona PS prosthesis for RSA - 15 Patients with NexGen LPS prosthesis and 15 patients with Persona PS prosthesis for Fluo The study population will consist of patients with symptomatic osteoarthritis of the knee scheduled for TKR surgery at the Department of Orthopaedics, Leiden University Medical Center. Annually 40 TKA procedures are performed in our department, of which about 70% is Osteo Arthritis (OA) and 30% Reumatoid Arthritis (RA). We anticipate that inclusion can be accomplished within a 2 year period. Main study parameters/endpoints are: - Migration, measured by means of RSA. - Prosthesis placement and bone resection measured by means of CT and caliper measurements of the resected bone parts. - In vivo kinematics by means of fluoroscopy. - Patient Reported Outcome Measures by means of questionaires.
The PFC Sigma Knee by DePuy Synthes is an excellent knee replacement with an excellent clinical track record, good survival rates (98% 10 years survival in patients aged < 55 years)(Keenan et al., 2012) and minimal early migration as measured with RSA (0.5mm MTPM at two years follow-up)(von et al., 2009). The ATTUNE™ Knee by DePuy Synthes is an advancement in knee replacement options. It is designed to provide better range of motion and address the unstable feeling some patients experience during everyday activities, such as stair descent and bending. To date (March 2013), more than 3,500 patients have received an ATTUNE Knee as part of a limited launch and positive feedback was received regarding patient recovery, stability and motion. The objective of this study is to accurately assess and compare migration, clinical and radiological outcome and patient reported outcomes of two TKR prostheses: the Cemented ATTUNE™ Fixed Bearing Cruciate Retaining Knee System and the Cemented PFC Sigma Fixed Bearing Cruciate Retaining Knee System, both by DePuy Synthes, Warsaw, Indiana, USA. The primary objective of this study is to compare the magnitude and pattern of migration of the prostheses (Femoral and Tibial component). The secondary objective of this study is to compare clinical and radiological outcome of the prostheses and PROMS. The tertiary objective of this study is to compare clinical and radiological outcome and PROMS of the prostheses with migration data. This study is designed as a single-blind, randomized trial between the ATTUNE™ Knee System and PFC Sigma Knee System. 32 patients with the ATTUNE™ Knee System and 32 patients with PFC Sigma Knee System will be included in this study. The study population will consist of patients with symptomatic osteoarthritis of the knee scheduled for TKR surgery at the Department of Orthopaedics, Medisch Centrum Haaglanden, The Hague, The Netherlands. Annually 300 TKA procedures are performed in this department, of which about 90% is Osteo Arthritis (OA) and 10% Rheumatoid Arthritis (RA) and other indications. We anticipate that inclusion can be accomplished within a 1 year period and that the total study duration is 3 years. Main study parameters/endpoints are: - Migration of the prosthesis with respect to the host bone measured by means of roentgen stereophotogrammetric analysis (RSA). - Patient Reported Outcome Measures by means of questionnaires.
