Filter by:Previous studies have investigated the outcomes of Knee Arthroplasty (KA) following Bariatric Surgery (BAS), but with substantial limitations as not stratifying for Body Mass Index (BMI) at time of KA or not addressing the type of BAS (gastric bypass, banding or sleeve). Since BMI varies greatly in patients with previous BAS, it is likely that BMI affects outcomes after KA in BAS-operated patients. The investigators believe that stratifying for BMI would explain the contradictions with the previous research in this patient group when it comes to the risk of revision after KA.
Dextrose prolotherapy is a controversial injection therapy in sports medicine. Currently, 25% hypertonic glucose solution is commonly used in clinical practice. Although this method has a certain therapeutic effect, there is still some controversy about the molecular mechanism of dextrose prolotherapy. In the past, it was thought that local stimulation would increase inflammatory reactions such as local leukocyte and macrophage infiltration and restart the "self-healing mechanism." However, some studies have pointed out that this treatment can cause cell apoptosis. In my clinical work, I often perform dextrose prolotherapy. I deeply feel the importance of exploring the detailed mechanism of action of this therapy in order to apply this therapy more appropriately to patients. We believe that the concentration of 25% hypertonic glucose solution should show a stepwise decrease in the joint cavity. Our preliminary cell experiment results using 2-fold serial dilutions of 25% glucose solution showed that 25%, 12% and 6% glucose solution will trigger the apoptosis of chondrocytes, vascular endothelial cells and immune cells, and will also inhibit the expression of the pro-inflammatory factor IL-6. Glucose solution below 3% will not have the effect of inducing apoptosis on cells. We believe that the therapeutic effect of 25% hypertonic glucose solution in the joint cavity may have cell-specific effects as the concentration changes dynamically. Therefore, in this study, we will clarify the therapeutic mechanism of dextrose prolotherapy for arthritis through basic research and clinical specimen analysis. The clinical research part will use clinical synovial fluid specimens to verify the therapeutic mechanism of hypertonic glucose dissolution. The joint pain level assessment of different types of patients (OA and RA) before dextrose prolotherapy (preliminary period), 1 month after treatment (midterm period) and 3 months after treatment (late period) will be collected, and joint effusion will be measured. Further analyze the cell apoptosis and concentration changes of inflammatory response factors in the liquid. We hope that through this study, we will have a clear understanding of the molecular mechanism of dextrose prolotherapy on joint component cells. This result will have reference value for the more appropriate application of dextrose prolotherapy in the treatment of human cartilage-related lesions.
The goal of this clinical trial is to compare the function of the knee after retaining or sacrificing the anterior cruciate ligament in robotic assisted knee arthroplasty. The main questions it aims to answer are: Does retaining the anterior cruciate ligament improve postoperative gait? Participants will perform - Gait analysis - Stair performance test - CT based Micromotion analysis of the implant micromovement
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.
This interventional study aims to compare the effectiveness of local multimodal drug periarticular injection in TKA patients with the standard pain control regime that includes opioids, NSAIDs, and other analgesics. The main questions The investigators strive to answer are: Is there a significant difference in the severity of pain and functional outcomes when applying periarticular injections? Are there any increased complications when applying the periarticular injections?
Total Knee Arthroplasty (TKA) is actually the most effective treatment option for patients with end-stage osteoarthritis (OA). However, nearly 20% of patients who underwent TKA remain unsatisfied with their clinical outcome. Investigating modifiable factors that limit knee functioning following TKA we may notice the significance of lower limb muscles strength. Gait pattern is also affected by OA, as arthritic knee joint cannot provide proper range of motion (ROM) and stability.Therefore any deviation in biomechanics should be noticed and analyzed. After TKA patients' physical function may change, but the study should be conducted to prove whether it improves or not. Patient-reported outcome defined by OKS (Oxford Knee Score) and FJS (Forgotten Joint Score) questionnaires will be evaluated.
The study is a nationwide, register-based cohort survey study. The objective of this study is to investigate whether weight change is associated with the incidence of persistent postoperative pain following total hip arthroplasty and knee arthroplasty across non-obese and obese and patients.
The present study is a multi-center randomized prospective non-inferiority trial. The study's primary objective is to compare the coagulation profile upon using two different TXA administration strategies: empirical TXA administration vs. viscoelastic test-based goal-directed TXA administration in high-risk non-cardiac surgery. The secondary objectives include comparing the amount of bleeding, incidents of hyper-fibrinolysis, thromboembolic complications, and postoperative seizures. Researchers assumed that goal-directed tranexamic acid (TXA) administration using viscoelastic field tests would not be inferior to the empirical TXA administration strategy in reducing postoperative bleeding and hyper-fibrinolysis. It also would be beneficial in lowering TXA-induced thromboembolic complications and seizures.
This study is a nationwide cross-sectional survey on pain and satisfaction after knee arthroplasty (KA). Please find the full protocol uploaded at ClinicalTrials.gov The goal of this observational study is to study pain and satisfaction in patients operated with knee arthroplasty. The main question it aims to answer are: - What is the incidence of persistent postsurgical pain in unselected knee arthroplasty patients - What is the level of satisfaction in unselected knee arthroplasty patients? Participants will be asked to answer a 22-item questionnaire.
The goal of this clinical trial is to develop an pharmacist-led preoperative opioid taper intervention for patients undergoing total knee or hip replacement who are on chronic opioids before their surgery. The main questions it aims to answer are: - Is the intervention feasible and acceptable to patients? - Does the intervention result in a decrease in opioid dose during the preoperative period? Participants will meet with a clinical pharmacist, who will provide some basic education on pain and opioids, and will propose an opioid taper schedule. The pharmacist will then follow-up with the participant by phone each week until surgery to assess progress and adjust the taper as necessary.
