Filter by: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.
The goal of this interventional study is to examine whether a pain management technique of combined femoral and popliteal nerve block is effective in total knee arthroplasty patients. The main questions it aims to answer are: Are there differences in postoperative outcomes? Does the nerve block, age, preoperative quadriceps muscle strength and Oxford Knee Score of the patient predict early functional ability? Participants underwent total knee arthroplasty and assessments. Researchers compared pain management techniques to assess effects on postoperative outcomes and identified the importance of preoperative variables a predictors of early functional ability. Further research is required to refine postoperative pain management strategies.
The goal of this clinical trail is to investigate if specific active exercises, with a certain daily frequency improves the range of motion (ROM) in the knee joint after primary- or revision total knee arthroplasty (TKA) The main questions it aims to answer are: - Does it make a difference to the ROM of the knee joint to do specific active exercise 2 times a day compared to 8 times a day in an 18 days period of time - Analyze if range of motion in the knee joint after TKA has an impact on self-reported activity, pain and physical activity Participants will be instructed by a physiotherapist to do a specific exercise to improve the flexion of the knee-joint and and other to improve the extension of the knee-joint. One group will be instructed to do the exercises 2 times a day the other group to do the exercises 8 times a day in total of 18 days The two groups will be compared to see if there is an effect in ROM and if the effect is significant between the groups if the intervention is done 2 times versus 8 times a day.
Total knee replacement is used in the treatment of patients with knee arthritis, rheumatoid arthritis and other knee disorders. Today, there are basically two designs; It cuts the posterior cruciate ligament (PS) and protects the posterior cruciate ligament (CR). Although there is no clear study suggesting which design is better, research on this subject has increased recently. the investigators aim is to define the superiority of these two designs over each other. Preoperative and postoperative joint range of motion examinations were performed on both knees separately. WOMAC and OXFORD scores were examined separately for both knees.
