Filter by:The objective of this study is to determine and compare the in vivo kinematics and vibroarthrography (VAG) signals for subjects implanted with Journey II Bi-Cruciate Stabilized (BCS), CR (Cruciate Retaining), and Bi-Cruciate Retaining (XR) TKAs.
Chronic pain is an extremely disabling disease. It is a major public health problem due to the lack of effective therapy. Chronic postoperative pain (CPOP) is defined by a painful symptomatology in the operated area unrelated to previous pain, present for more than 3 months, and without any link to surgical complication. The prevalence of chronicization of postoperative pain is 30% after total knee arthroplasty. Identification of clinical, biological and psychological profiles are crucial to prevent CPOP. A biologic factor, Brain Derived Neurotrophic Factor (BDNF) produced by a variety of cells is a key regulator of neuroplasticity. BDNF is increasingly studied in the mechanisms of cerebral sensitization and pain chronicization. The role of BDNF in pain of patients remains to be explored in a prospective study. The aim of this observational study is to compare the kinetics of BDNF after total knee arthroplasty in patients with and without CPOP. Patients will be included in the study at the preanesthetic consultation. Serum BDNF levels will be measured preoperatively, 48h postoperatively, 3 and 6 months after surgery.
Total knee arthroplasty (TKA) is one the most common surgical treatments performed for end stage degenerative arthritis of the knee. More than 700,000 procedures are currently performed yearly in the United States. This procedure usually results in moderate-to-severe pain in the immediate post-operative period. Optimal pain control may allow early mobilization, accelerate rehabilitation, improve patient satisfaction, decrease length-of-stay, and optimize functional outcomes. The challenge, however, is to manage pain with alternative methods, reducing the role of opiate medications, which are highly addictive with myriad side effects. In this prospective randomized double-blinded controlled study, the investigators aim to evaluate the benefits of an over-the-counter (OTC) transdermal CBD preparation in patients undergoing primary total knee arthroplasty as a novel adjunct to the standard multi-modal analgesic regimen, to reduce postoperative pain and reduce the need for opiates after total knee arthroplasty.
Considering that the high local concentration of antibiotic from bone cement is delivered intravenously through the self-transfusion process, systematic toxicity has never been evaluated. In addition, the effectiveness of self-transfusion with the routine concomitant use of other modern blood-salvage strategies, like tranexamic acid, should be also assessed. Therefore we performed a randomized study to assess: 1) the safety of self-transfusion in TKA by comparing the gentamicin concentrations resulting from the use or not of autologous blood transfusion. 2) the efficacy of self-transfusion in TKA, with the concomitant administration of tranexamic acid. The serum concentration of aminoglycosides has been measured in two groups of 20 patients each, after TKA, according to the use of self-transfusion. Hemoglobin, renal function and calculated blood loss were compared at several time points between groups.
To compare the functional outcomes between cemented and cementless TKA in bilateral knee replacement patient.
Serum cytokines was assosiated with symptoms and progression of osteoartritis. It is unknown whether these cytokines have a predictive role on severity of symptoms after total knee arthroplasty (TKA) or not. The aim of this study is to investigate the relationships between the preoperative serum cytokine level (SCL) and lenght of stay in hospital, postoperative pain intensity, functional status, joint position sense and X ray. Grade 4 osteoartritis degeneration who intern the hospital for total knee arthroplasty surgery. Serum Cytokine Levels (IL-6, TNFα, IL-1β) will be assessed before surgery. Pain intensity at rest/activity and valgite angle will be evaluated before surgery, postoperative 72 hour and postoperative 6 weeks. Functional status and joint position sense will be assessed before surgery and 6 weeks after surgery. Lenght of stay in hospital (LOS) will be recorded.
Background and Aims: Music therapy has a wide range of uses in health care practice. The aim of this study was to investigate the effects of intraoperative music played during spinal anesthesia operation on the patients' intraoperative vital signs, postoperative pain, and anxiety status. Methods: The study was performed in an operating room with a total of 90 patients, of whom 30 were in the music group, 30 were in the control group and 30 were in the sedated group. The ethics committee's approval, institutional permission, and the study participants' written informed consent were obtained. Data were collected using patient information and intraoperative observation form for vital signs as well as through the Visual Analog Scale and State Anxiety Scale. Preoperative and postoperative anxiety, the intraoperative and postoperative vital signs and postoperative pain and anxiety of all groups were analyzed.
Rehabilitation is an important part of the post-operative treatment after TKA by consensus. This study intends to analysis whether fast inpatient rehabilitation after TKA can improve knee joint or general function, and ultimately explore for effects and values of fast inpatient rehabilitation after TKA.
Due to swelling after total knee arthroplasty, postoperative mobilization and training is impeded in addition to higher pain level in patients. With postoperative compressive stockings to prevent oedema, haematoma and postoperative pain we would like to investigate if compressive stockings reduce postoperative swelling and pain and furthermore improve mobilization and knee function. In this randomized controlled trial, 88 patients are randomized in two groups. One group receives postoperatively compressive stockings for a period of 6 weeks. The control group is treated without compressive stockings. The patients compressive stockings wearing compliance is controlled with a temperature sensitive sensor. The patients will be informed about the implantation of the sensor. Outcome measures are knee- calf- and ankle swelling in mm, pain, WOMAC and KSS score preoperatively and at 12 weeks, 12 months and 24 months.
The objective of this study is to obtain implant survivorship and clinical outcomes data for the commercially available MPS-Flex® Total Knee Joint Prostheses used in primary total knee arthroplasty (TKA).
