Filter by:This is a randomized (1:1) placebo-controlled clinical trial to determine the feasibility and effectiveness of 30-day application of NEUROCUPLE™ patch for pain reduction and opioid consumption following TKA. Results will establish NEUROCUPLE™ as an effective non-opioid postoperative pain management device for FDA approval. Importantly, we have a placebo device (device without the captor array layer) that looks exactly like the active device, allowing us to conduct a true placebo randomized study.
The purpose of this study was to investigate whether polyethylene (Vitamin E-containing polyethylene), which has been newly introduced and widely used clinically as a biomaterial for tibial inserts in total knee arthroplasty, but whose mid- to long-term clinical results are still unknown, is more effective than conventional polyethylene. Our goal is to clarify through an international multi-center joint study using in vivo polyethylene wear particle analysis, which the investigators developed as a method to provide early feedback, as to whether polyethylene wear debris production in vivo can be reduced.
Immediate rehabilitation after total knee arthroplasty (TKA) differs in terms of volume, intensity but also type of treatment. Continuous passive motion after TKA is so far only investigated for replacing physiotherapy. This study is conducted to investigate CPM when it partially replaces group physiotherapy in terms of functional and patient-reported outcomes.
Patients having knee replacement surgery regularly experience joint pain and compromised bone quality leading to implant loosening and periprosthetic fractures. The role of the gut microbiome, which is the collection of bacteria and other microbes within the human gastrointestinal tract, is just beginning to be recognized, including its potential effects on pain, infection, and loosening after total joint replacement. Antibiotics are regularly used in orthopaedic surgery to reduce the risk of infection, but they also harm gut microbiota and reduce their potentially beneficial effects. Probiotics may have a role to play in enhancing bone quality and decreasing synovial inflammation after joint replacement surgery, and this study will explore the potential relationship of probiotic use with implant migration, bone density, and patient outcomes. This study is a randomized, controlled, double-blinded trial comparing probiotic use with placebo in post-menopausal women undergoing primary total knee replacement. The main questions it aims to answer are: - to compare implant migration between groups from baseline to six weeks post-surgery - to compare bone density and joint inflammation between groups from baseline to six weeks post-surgery - to compare gut microbiome composition and patient-reported outcome measures between groups from baseline to six weeks post-surgery
The aim of the study is to measure the validity and reliability of the StUD test in patients with TKA. Forty-seven patients with primary TKA included in this study. The test-retest reliability of the StUD test was measured with 1-hour interval. Validity was assessed that the 30s Chair Stand Test (30sCS), the Hospital for Special Surgery score (HSS) and Short Form-12 Quality Life Questionnaire (SF-12) were used as comparator instruments.
The goal of this RCT is to compare efficacy between mirogabalin and pregabalin in pain reducing after unilateral primary total knee arthroplasty. The main question[s] it aims to answer are: • Does mirogabalin have better pain reduction than pregabalin after unilateral primary total knee arthroplasty. Participants will randomized to mirogabalin or pregabalin group and will take the drug for 6 weeks after TKA. Researchers will compare to pregabalin group to see pain and functional outcomes after TKA.
REAL INTELLIGENCE™ CORI™ (CORI Surgical System) is a computer-assisted orthopedic surgical system. CORI Surgical System is designed to aid surgeons in planning and executing a procedure involving bone preparation for total knee arthroplasty (TKA) procedures. CORI Surgical System is comprised of a console control unit, optical tracking camera, primary and secondary input displays (tablet and optional display monitor), and foot pedal. The CORI Surgical System software consists of a patient and user management module, a surgical planner, and an intra-operative cutting module. Yuanhua Orthopaedic Robotic Systems, KUNWU, is an open-platform robotic system that does not restrict surgeons in choosing the type of prosthesis implant. It is the only Orthopaedic Robotic System in Hong Kong registered with the HK Department of Health Medical Devices Control Office (MDCO) as an open platform system. Unlike other manufacturer's implant-based robots (closed systems), Yuanhua's objective is to provide maximum flexibility in choosing the best implant for each patient. Closed system robots not only impact the surgeon's choice of implant for an individual patient but also affect the hospital's implant purchases over multiple years without any negotiation power on pricing. This business model is often referred to as a "razor and razor blade" model. The primary objective of this study is to evaluate the use of open and closed platform robotic-assisted TKA procedure in achieving post-operative leg alignment as compared to procedures using standard instruments. The secondary objective of this study is to assess the safety and performance of the robotic-assisted TKA procedure up to 12 months after surgery as compared to procedures using conventional manual instruments.
ABSTRACT INTRODUCTION Knee osteoarthritis is a common joint pathology causing joint pain and ambulatory limitations. In primary total knee arthroplasty (TKA) surgeries, medial parapatellar (MP) and subvastus (SV) approaches are frequently used. The MP approach provides good exposure and is more widely used. In the SV approach, the vastus medialis muscle is preserved. Some argue that the extensor mechanism may heal earlier with the SV approach. In this study, unlike previous studies, the investigators aimed to quantitatively compare the early outcomes of MP and SV approaches, through shear wave elastography (SWE) measurements isolated over the vastus medialis and vastus lateralis muscles. MATERIALS AND METHODS The study included 20 patients with indications for TKA due to primary osteoarthritis, divided into MP and SV groups. SWE measurements of the vastus medialis and vastus lateralis muscles were performed preoperatively and at 3-month follow-up. Clinical scores (Knee Society Score and WOMAC) and straight leg raising time were recorded both preoperatively and postoperatively.
The goal of this study is to compared efficacy of oral fluid and intravenous fluid after primary unilateral total knee arthroplasty. The main question it aims to answer is: Does oral fluid replacement after primary unilateral total knee arthroplasty provide a patient recover faster than intravenous fluids replacement?
This study is a prospective study which compares of Modified Post-Anesthetic Discharge Scoring System (PADSS) between 6 and 24 hours in patients undergoing total knee arthroplasty in Thammasat University hospital, Thailand.
