Filter by:Background Bone irrigation is essential in cemented total knee arthroplasty surgical technique in order to improve cement penetration and interdigitation into cancellous bone, that is going to determine the strength of the bone-cement interface. Purpose To report the effect of high-pressure pulsatile lavage versus manual rinsing on bone cement penetration in total knee arthroplasty. Methods This is a single-centre, prospective, randomized, controlled clinical trial. The study included 100 patients undergoing primary total knee arthroplasty. All patients meeting inclusion criteria were randomly assigned to the pulsed lavage or non-pulsed lavage group. The cumulative bone cement penetration was radiologically assessed in antero posterior and lateral radiograph views in 10 zones according to the Knee Society Scoring System. A statistical analysis was performed between both groups comparing bone cement penetration cumulative scores.
The indicators of patient recovery in the postoperative period include sleep, physical functionality, mental health, cognitive functionality, pain, and psychosocial functionality. This thesis aims to investigate the effects of progressive relaxation exercises on postoperative pain intensity, sleep quality, and recovery in patients undergoing total knee arthroplasty.This study, designed as a randomized controlled experimental study, will be conducted between September 1, 2023, and August 1, 2024, at ÇAYCUMA State Hospital in ZONGULDAK province, Turkey, among patients undergoing total knee arthroplasty. A total of 96 patients will be recruited based on the sample size calculated using G-power analysis. Through block randomization, 48 patients will be assigned to the intervention group and 48 patients to the control group. Data will be collected using the Numeric Rating Scale for pain, the Richard-Campbell Sleep Scale, a sleep tracker smart wristband to measure sleep quality and duration, the Postoperative Recovery Index, and a Patient Information Form.
The objective is to know the effects of Neuromuscular Electrical Stimulation (NMES) and its combination with Blood Flow Restriction (BFR) Therapy in healthy amateur female soccer players.
The knee is the most stressed and exposed joint in sports practice (70 to 85% of Anterior Cruciate Ligament ruptures occur during sports activities). Although traumatic knee injuries are already described in radiology and 1.5 Tesla and 3 Tesla MRI, there are cases of post-traumatic knee pain with a normal MRI (with a risk of underestimating a traumatic injury that may worsen without appropriate treatment) and cases of "ambiguous" MRI findings (uncertainty between low or high-grade ligament or meniscal injury, presence or absence of meniscal attachments, complete versus partial rupture of the Anterior Cruciate Ligament, associated cartilage lesion versus intact cartilage), which directly impact orthopedic or surgical therapeutic management.
The current proposal aims to investigate the patellar tracking in adult patients receiving Journey II Bi-Cruciate Stabilized (BCS) total knee arthroplasty (TKA) before and one year after surgery, positioned with the CORI Robotics System instrumentation. The hypothesis is that less change in patella tracking before and after surgery will lead to less anterior knee pain complaints. Patella tracking is investigated using 4Dimensional Computer Tomography (4D CT) imaging. Researchers will compare the group of participants that will receive a patella onlay button with the group that will not receive a patella onlay button with their TKA to see if there is a difference in motion and pain experienced by the participants.
This is a prospective study-registry on preoperative patient characteristics and postoperative complications in patients having fast-track hip and knee replacement surgery in 8 Danish dedicated arthroplasty departments from all five health regions in Denmark. The registry consists of detailed patient and physician reported preoperative characteristics and including prescribed medication and lab results. Follow-up is based on electronical medical records by dedicated nurses with physician backup and includes Clavien-Dindo and Comprehensive Complication Index scoring. All patients having day-surgery also completes a patient reported questionaire on health-care utilization and return to work by day 30. Finally, a machine-learning algorithm for identification of "high-risk" patients based on he preoperative data is included.
This randomized controlled trial (RCT) will compare the effects of melatonin vs. placebo in patients undergoing primary total knee arthroplasty (TKA). This RCT aims to study the effects melatonin has on sleep quality after TKA. Patients will be blinded to their respective groups and will be instructed to take either 5mg melatonin or a placebo pill (Vitamin C) for 6 weeks postoperative. Sleep quality surveys will be administered preoperatively and post-operative week 6, 90-days and 1 year. Poor sleep quality is a common issue faced by patients undergoing TKA. The goal of this study is see if melatonin can improve postoperative sleep quality, and if so, does improved sleep quality correlate to improvements in other postoperative outcomes.
The aim of the study is to evaluate the myofascial chain lines in addition to the general evaluation parameters in patients with patellofemoral pain syndrome (PFPS) and to determine whether deviations from normal in the myofascial structure have an effect on the development of PFPS. There will be two groups in this study. One of the groups will consist of 28 patients aged between 25-50 years. The other group will consist of 28 healthy individuals between the ages of 25-50 years. Postural problems that can be seen in the superficial anterior myofascial chain line will be evaluated. These problems: forward head, q-angle, genu varum, genu valgum, foot postural problems (pes planus, pes kavus vb.) and pelvic tilt. In addition to all these assessments, knee pain and the biomechanical properties of the anterior myofascial tissue will be evaluated.
A unicompartmental (partial) knee replacement (UKR) is the removal of one part of the knee joint (a condyle), that has become damaged due to osteoarthritis, and replacing it with an artificial implant. The placement of these artificial implants and how they are aligned with each other is important because they can impact overall knee function and the long-term survival of the implant. A UKR is a highly effective, recognised procedure for patients with end-stage osteoarthritis affecting one compartment of the knee joint. The functional outcomes following UKA are at a minimum of equivalence to total knee arthroplasty procedures, with some recent literature demonstrating improved functional patient reported outcome scores. There have been significant developments in knee replacement surgery over recent years. In particular, the introduction of robotic surgical systems, such as the NAVIO and CORI systems (Smith+Nephew Plc). These systems are hand-held devices which can support the surgeon with the knee replacement procedure, the systems are image-free and do not require the patient to undergo any scans (such as CT scans). Comparisons of robotic systems to conventional instruments have demonstrated that robotic platforms produce fewer positioning errors in total knee replacement. This can result in more precise knee alignment and better outcomes following surgery. With both the NAVIO and CORI Surgical Systems there is a reduction in radiation exposure due to them being image-free. At present, there is some evidence available for the long-term outcomes of knee replacement implanted using robotic assistance (i.e. 2-10 years) however this study is designed to look at the early outcomes following UKR. There is no literature to date to show that robotic-assisted UKR is superior to conventional methods, within the early post-operative period (up to 12 months). This study is designed to show that the NAVIO/CORI surgical systems are better than conventional methods for UKR. The hypothesis is that they will be cost-effective, will reduce the time a patient spends in hospital following their surgery, will improve patient satisfaction during the early recovery period and will improve the patient's early post-operative mobility and function.
A total knee replacement is the removal of parts of the knee joint, that have become damaged due to osteoarthritis, and replacing these with artificial implants. The placement of these artificial implants and how they are aligned with each other is important because they can impact overall knee function and the long-term survival of the implant. It is reported that up to 34% of all patients following total knee replacement (TKR) have poor outcomes functionally. There have been significant developments in knee replacement surgery over recent years. In particular, the introduction of robotic surgical systems, such as the NAVIO and CORI systems (Smith+Nephew Plc). The NAVIO and CORI Surgical Systems are hand-held devices which can support the surgeon with the knee replacement procedure, the systems are image-free and do not require the patient to undergo any scans (such as CT scans). During the surgery, the surgeon uses the NAVIO/CORI hand-held device to map specific landmarks within the knee joint and determines the desired alignment using associated computer software. The tools to remove the bone and place the implants are controlled by the surgeon with the guidance of the NAVIO/CORI software. Comparisons of robotic systems to conventional instruments have demonstrated that robotic platforms produce fewer positioning errors in total knee replacement. This can result in more precise knee alignment and better outcomes following surgery.
