Filter by: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.
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 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.
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.
The objective of this prospective study is to demonstrate accuracy of a limp detection model using a healthcare provider assessment as the non-reference standard.
In our institution, many patients undergo staged bilateral total knee arthroplasty at weekly intervals, and most of the patients are older adults with degenerative arthritis. As recommended, the older adult patients who undergoing total knee arthroplasty drink carbohydrate-containing fluid (400 ml) 2 hours prior to surgery. In this type of surgery, there are additional points to consider when applying the fasting guidelines. This is because, in addition to the factor of advanced age, which can affect gastric emptying time, the patient's physical, medical, and psychological conditions at the first and the second operation may be different. For example, the effect of the acute pain that occurs after the first total knee arthroplasty and subsequent opioids administered on gastric motility cannot be ignored. However, to date, there have been no studies examining the association of stress (emotional and surgical) and residual gastric volume of older adult patients with staged bilateral total knee arthroplasty and whether there is a difference according to the stage when carbohydrate-containing fluid is ingested. In the present study, the investigators will evaluate the effect of emotional stress, surgical stress, pain, and the use of opioids on the residual gastric volume in older adults undergoing staged-bilateral total knee arthroplasty.
Mobilization and rehabilitation are essential components of a successful functional recovery following total hip and knee arthroplasties. Currently, we have no good measure of how mobile patients are after their surgery. Recent technological advances in personal activity monitors, such as the Fitbit, might provide medical providers and patients the opportunity to more objectively monitor their postoperative mobility and recovery course. However, these consumer activity monitors have yet to be validated in terms of their accuracy and utility for monitoring mobility in the immediate postoperative setting in arthroplasty patients. Our goal is to validate one of the most popular consumer activity monitors, the Fitbit Zip, in the postoperative total joint arthroplasty patient population.
