Filter by:The purpose of this study is to monitor the performance of a large metal-on-metal bearing from the DePuy ASR™ System in the treatment of patients with hip joint disease requiring hip resurfacing surgery or a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. The Study was terminated with effect from 30th November 2011 following the completion of 2 year follow up assessments for those patients remaining in the study. Please note that prior to this decision DePuy voluntarily recalled the ASR products on 24 August 2010. Additional information regarding this voluntary recall and the follow-up of patients affected by the recall can be found at the following links http://www.mhra.gov.uk/Publications/Safetywarnings/MedicalDeviceAlerts/CON155761 and http://www.depuy.com/countries_list.
The purpose of this study is to monitor the performance of the Pinnacle™ Cup with a ceramic-on-ceramic bearing combination in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments.
50 patients are randomized to two groups who receive a navigated knee prosthesis. Aim of the study is a comparison between a minimally invasive and a conventional approach. In both groups OrthoPilot computer assisted-navigation will be used. Pain intensity as well as concomitant pain medication are monitored during the first 20 postoperative days and will be compared for the two groups. Various scores are surveyed.
The purpose of this study is to evaluate the use and efficacy of the Encore Foundation Knee System in a group of 200 patients for whom data has already been collected.
This study is being conducted to gather medium and long-term information regarding the performance and safety of the commercially available DURALOC® Option Ceramic-on-Ceramic Hip Prosthesis System.
The purpose of this study is to determine if patients with a fixed-bearing or mobile-bearing partial knee replacement perform functional activities differently than patients that have had total knee replacement or healthy volunteers that have not had knee surgery. The activities we are interested in include getting up out of a chair, stepping up and over a small wooden box, and standing still with the knees straight and also bent to 45 degrees.
Prospective, randomized study of Summit Porocoat versus Summit DuoFix HA in total hip arthroplasty
The purpose of the study is to evaluate the clinical performance of the cruciate ligament retaining or cruciate ligament substituting implants by obtaining a series of primary TKAs. Outcome scoring and radiographic assessment will be the methods used to evaluate performance.
This post-market clinical follow-up study was designed to compare hip replacement outcomes of the European Hip against 3 controls (Omniflex, Zweymuller, and Spotorno), however Omniflex did not end up being used. The first patient had surgery on February 18, 2000 and the final patient had surgery on September 2, 2005. There were 317 subjects consented but only 301 had hip replacement surgery (subjects received: 220 European hips, 33 Zweymuller, and 48 Spotorno). The study took place at three sites. Each site used their standard device as the control. The Austrian site enrolled 69 European hips and 33 Zweymuller hips. 92 European hips and 48 Spotorno hips were enrolled in Germany. Finally, the site in Italy enrolled 59 European hips. Although the study protocol intended collecting DEXA and RSA outcomes, the data collected by the sites did not include these outcomes.
The purpose of this study is to monitor the performance of the DePuy PROXIMA™ hip in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. A subset of patients will undergo scans to allow the bone mineral density of the bone surrounding the implant to be monitored
