Filter by:The knee is the most stressed and exposed joint in sports practice (70 to 85% of Anterior Cruciate Ligament ruptures occur during sports activities). Although traumatic knee injuries are already described in radiology and 1.5 Tesla and 3 Tesla MRI, there are cases of post-traumatic knee pain with a normal MRI (with a risk of underestimating a traumatic injury that may worsen without appropriate treatment) and cases of "ambiguous" MRI findings (uncertainty between low or high-grade ligament or meniscal injury, presence or absence of meniscal attachments, complete versus partial rupture of the Anterior Cruciate Ligament, associated cartilage lesion versus intact cartilage), which directly impact orthopedic or surgical therapeutic management.
A unicompartmental (partial) knee replacement (UKR) is the removal of one part of the knee joint (a condyle), that has become damaged due to osteoarthritis, and replacing it with an artificial implant. The placement of these artificial implants and how they are aligned with each other is important because they can impact overall knee function and the long-term survival of the implant. A UKR is a highly effective, recognised procedure for patients with end-stage osteoarthritis affecting one compartment of the knee joint. The functional outcomes following UKA are at a minimum of equivalence to total knee arthroplasty procedures, with some recent literature demonstrating improved functional patient reported outcome scores. There have been significant developments in knee replacement surgery over recent years. In particular, the introduction of robotic surgical systems, such as the NAVIO and CORI systems (Smith+Nephew Plc). These systems are hand-held devices which can support the surgeon with the knee replacement procedure, the systems are image-free and do not require the patient to undergo any scans (such as CT scans). Comparisons of robotic systems to conventional instruments have demonstrated that robotic platforms produce fewer positioning errors in total knee replacement. This can result in more precise knee alignment and better outcomes following surgery. With both the NAVIO and CORI Surgical Systems there is a reduction in radiation exposure due to them being image-free. At present, there is some evidence available for the long-term outcomes of knee replacement implanted using robotic assistance (i.e. 2-10 years) however this study is designed to look at the early outcomes following UKR. There is no literature to date to show that robotic-assisted UKR is superior to conventional methods, within the early post-operative period (up to 12 months). This study is designed to show that the NAVIO/CORI surgical systems are better than conventional methods for UKR. The hypothesis is that they will be cost-effective, will reduce the time a patient spends in hospital following their surgery, will improve patient satisfaction during the early recovery period and will improve the patient's early post-operative mobility and function.
A total knee replacement is the removal of parts of the knee joint, that have become damaged due to osteoarthritis, and replacing these with artificial implants. The placement of these artificial implants and how they are aligned with each other is important because they can impact overall knee function and the long-term survival of the implant. It is reported that up to 34% of all patients following total knee replacement (TKR) have poor outcomes functionally. There have been significant developments in knee replacement surgery over recent years. In particular, the introduction of robotic surgical systems, such as the NAVIO and CORI systems (Smith+Nephew Plc). The NAVIO and CORI Surgical Systems are hand-held devices which can support the surgeon with the knee replacement procedure, the systems are image-free and do not require the patient to undergo any scans (such as CT scans). During the surgery, the surgeon uses the NAVIO/CORI hand-held device to map specific landmarks within the knee joint and determines the desired alignment using associated computer software. The tools to remove the bone and place the implants are controlled by the surgeon with the guidance of the NAVIO/CORI software. Comparisons of robotic systems to conventional instruments have demonstrated that robotic platforms produce fewer positioning errors in total knee replacement. This can result in more precise knee alignment and better outcomes following surgery.

Background: The JOURNEY II BCS Total Knee System (JOURNEY II Bi-cruciate Stabilized Total Knee System) consists of femoral component made from oxidized zirconium (OXINIUM) The JOURNEY II CR Total Knee System (JOURNEY II Cruciate Retaining Total Knee System ) consists of femoral component made from oxidized zirconium (OXINIUM) Purpose: Post-market evidence generation for JOURNEY II BCS and JOURNEY II CR Total Knee System Objectives: 1. Evaluate the performance of JOURNEY II TKA in Asia-Pacific (APAC) patient populations 2. Establish the equivalent performance between JOURNEY II BCS and JOURNEY II CR to support adoption of JOURNEY II CR Research participants / locations: A total of at least 176 knees' information will be collected in up to 10 sites. There will be at least eighty-eight (88) knees for JOURNEY II CR TKA group and at least 88 knees for JOURNEY II BCS TKA group.
This is a randomized prospective outcomes study comparing two groups of patients. One group will receive liposomal bupivacaine for a periarticular injection. The other will receive ropivacaine for periarticular injection for pain relief after Total Knee Arthroplasty. the primary objective of this study is to determine if liposomal bupivacaine provides superior pain control (decreased maximal pain scores within the first 72 hours post surgery) when compared to ropivacaine when injected in a periarticular injection.
This study compares the fill of bone graft sites in the knee. It is hypothesized that harvest sites, voids, and defects caused by trauma that are treated with the OsseoFit™ Porous Tissue Matrix™ device will achieve a better fill grade than those treated with the conventional method.
