Filter by:Background: The JOURNEY II CR Total Knee System consists of femoral component made from oxidized zirconium (OXINIUM) Purpose: Post-market evidence generation for JOURNEY II CR Total Knee System Objectives: Evaluate the performance of JOURNEY II CR TKA in APAC populations Evaluate the impact of patella resurfacing on the outcomes of JOURNEY II CR TKA Research participants / locations: A total of up to 480 knees' information will be collected in up to 15 sites in India, China mainland, Hong Kong, Singapore, Thailand and Japan There will be up to 240 knees for resurfaced patella group and up to 240 knees for un-resurfaced patella group.
Background: REAL INTELLIGENCE™ CORI™ (CORI Robotics) is a computer-assisted orthopaedic surgical navigation and burring system. CORI Robotics is designed to help surgeons in planning and executing certain types of knee surgery involving bone preparation. These types of surgery are called 'unicondylar knee arthroplasty' (UKA) and 'total knee arthroplasty' (TKA). Purpose: This study is being carried out to demonstrate the safety and effectiveness of the CORI Robotics. The data collected will be used to meet the post-market clinical follow-up requirement in Europe and to support claims and publications. Objectives: The primary objective of this study is to evaluate the use of CORI Robotics in UKA and TKA procedures in achieving post-operative leg alignment to check that the results of the operation are similar to what the surgeon originally planned. Research participants / locations: 140 research participants will be recruited from up to 8 sites in 4 countries globally (UK, US, Germany and India). There will be 70 patients having UKA surgery and 70 patients having TKA surgery.
The study objective is to assess patient satisfaction after the surgery with a custom-made CE marked implant (ORIGIN®) versus off-the-shelf (VANGUARD PS) device, and to document the clinical and device performance outcomes of the ORIGIN System used in routine hospital practice in a large patient cohort treatment of total knee arthroplasty. The hypothesis is that patients receiving ORIGIN implants will experience a more natural feel of the prosthesis during the first year after the surgery compared to patients receiving VANGUARD implants (as measured with FJS), and slightly significant improvement at the following interval of 2 years. The overall patient satisfaction is expected to be improved after 2 years follow-up. It is also supposed that the overall patient satisfaction is expected to be higher with ORIGIN PS than with VANGUARD PS treatment.
The purpose of this study is to evaluate the clinical functional results of the Triathlon All-Polyethylene Tibia Knee Device.
The goal of this double-blind prospective randomized study is to compare subjective outcome measures and gait parameters between conventional THA using large diameter femoral heads and total hip resurfacing
A prospective multicentre randomised clinical trial of 250 selected patients with THA, who will be randomly assigned to intervention (IG) or control group (CG). Both will have standard physiotherapy during hospitalisation, IG will additionally learn strength and sensory-motor training exercises. Follow up will be performed with physical tests, maximal voluntary isometric contractions and outcome assessment questionnaires at baseline and 1, 3 and 12 months after surgery.
The main objective of this pilot study is to determine if using a portable, accelerometer based, visual feedback system improves exercise quality. The secondary objective of this study is to investigate the effect of motivational targets by testing the effects of increasing ROM targets. The results from this study will be used to improve the visual feedback system of the Knee Connect system and serve as starting point for a larger clinical study.
Approximately 40% of patients undergoing total knee arthroplasty develop acute to moderate post operative pain. Furthermore 20-30% develop chronic post operative pain. The objective of this work is to study the effectiveness and safety of pulsed radiofrequency of the saphenous nerve realized during the pre-operative period of total knee arthroplasty. The study design is a randomized, blinded clinical trial. Patients scheduled for total knee arthroplasty are divided into two groups. The first group procedure consists in pre-operative pulsed radiofrequency under ultrasound guidance of the saphenous nerve and standard postoperative pain management by the pain clinic. The second group receives only the standard postoperative pain management by the pain clinic. Patient follow ups are performed 3 times (after 2 weeks, 2 months and 6 months) within a period of 6 months, evaluating pain severity using the VAS.
Total hip replacement (THP) is widely used for hip osteoarthritis treatment. Surgeons are constantly looking to improve all aspects related to this procedure weather is improvement of implant design, instrumentation or surgical technique. Excellent clinical and radiological results were observed at medium and long term in the last years for AMIStem system. This observational study has the objective to survey hip prosthesis stability and function of the operated hip in patients who are not exposed to surgical risks. The principal investigator will contact all patients in order to perform the follow-up visit according to standard practice. Patients operated between January 2010 and December 2011 will be invited in the study during the clinical visit organised according to standard practice. Preoperative clinical and radiological data, intraoperative details and postoperative follow-up data at 1-year will be retrospectively collected. Five-year and ten-year data will be prospectively collected after inclusion in the study.
The purpose of this study is to assess the positioning of customized guides designed from patients X-Rays (Materialise X-Ray Knee Guides) using computed tomography in primary total knee arthroplasty.
