Filter by:The purpose of this study is to monitor the performance and determine the metal ion release of the DePuy ASR™ System in the treatment of patients with hip joint disease requiring hip resurfacing surgery. 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 also have blood samples taken at regular intervals to allow the metal ion levels to be determined and undergo scans to allow the bone mineral density of the bone surrounding the implant to be monitored. DePuy decided to close this Study in 4Q 2009. The Study was terminated with effect from November 2010 to allow for the completion of the 5 year follow up assessments. Please note that subsequent 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/CON079157 and http://www.depuy.com/countries_list.
The purpose of this study is to monitor the stability of the C-Stem™ AMT hip within the thigh bone when used 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, standard x-ray assessments and special x-rays which allow the stability of the implant to be determined.
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.
To demonstrate the safety and efficacy of the Cormet Large Diameter Metal on Metal (LDMOM) Total Hip System using a composite clinical success (CCS) primary endpoint.
The purpose of this study is to investigate the analgesic efficacy and safety of tanezumab added on to diclofenac SR in patients with osteoarthritis of the knee or hip currently experiencing partial benefit from, and are tolerating, diclofenac 150 mg/day therapy.
Tanezumab reduces pain of osteoarthritis without affecting how nerve impulses are transmitted in sensory nerves.
Overall study design: A prospective, randomized, multi-center clinical studies comparing the minimal invasive and the standard surgical total knee replacement technique (control) using the Genesis II total knee system. The study will collect efficacy, safety and socio-economical data over 2 years. An additional 5 years follow-up interval is optional. The objectives (short-term follow-up) of the study are to: 1. Assess whether the improvement in Pain and Range of motion per Knee Society scoring system and VAS score. 2. Assess whether there are any differences between the surgical techniques as regards complication rate. 3. Assess whether the hospital stay and the rehabilitation time (Straight leg raise, Active/passive ROM) of the patients differs between the two techniques. 4. Assess the x-ray mechanical alignment between the two techniques. Attempts will be made to assess whether the collected peri-operative data (including incision length, blood loss, wound appearance, hospital readmissions and operative time) differs between the two surgical techniques. The primary objectives (mid-term follow-up) of the study are to: 1. Improvement in Pain and Function per Knee Society Scoring system 2. Number and Extent of Radiographic Lucencies >2mm 3. Revision and knee-related adverse events 4. Improvement in Quality-of-life via the VAS score 5 investigational sites will participate and enroll a total of approximately 250 patients over a 12 months period. Thus, each site will enroll 50 patients.
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 determine whether an intraarticular injection of Ozone into the knee joint is an effective therapy for pain control in patients with osteoarthritis of the knee.
