Filter by:Total knee arthroplasty(TKA) is a successful orthopedic surgery with excellent clinical outcome and survival. However, there are concerns about patient satisfaction in previous reports, and dissatisfaction rate of 15-30% is reported in clinical outcomes(PROMs) of some studies. Therefore, for improving the patient's outcome and satisfaction after total knee arthroplasty, it is necessary to change the design of the conventional total knee arthroplsaty implant. The knee is a joint structure with several dynamic functions, and not only the skeletal structure but also the soft tissue balance plays an important role in the function of the knee joint. New implants are being developed to overcome the limitations of conventional TKA implant, including the Journey II Bi-cruciate substituting total knee system (JII-BCS; Smith & Nephew). JII-BCS implant has normal articular geometry, more anatomical femoral shape, lateral tibial convex geometry, and asymmetrical tibial plateau, anterior and posterior cams, which has been shown in experimental studies to produce nearly normal knee movement by reproducing the actual normal anatomical alignment in vivo. The clinical results of the kinematic effects of this anatomcally aligned change are insufficient, and there is also a lack of comparative studies with conventional total knee arthroplasty implant. The purpose of this study is to compare outcomes between anatomically aligned TKA(JII-BCS) and conventional TKA(Legion total knee system, Smith & Nephew). This study is a randomized controlled study in patients undergoing total knee arthroplasty per day. Radiologic parameter, patients preference and clinical results was investigated in both knee of same patients who received TKA during minimum 2 year follow up.
Introduction: Hip and knee osteoarthritis (OA) was ranked in 2010 as the eleventh highest contributor to global disability. In France in 2014, non-spinal OA was the leading self-reported cause of morbidity among adults over sixty-five years of age, with a prevalence of 49.5 per cent. OA is known to be the first cause of disability in activities of daily life and a risk factor of frailty among people over seventy-five years of age. Despite its major impact on the elderly population's quality of life and health, quality of care for OA in elderly patients remains understudied. Objective: The study aims to assess the quality of care for knee and hip OA in patients aged 75 years and over.
Using double-blind, randomized controlled design to compare the immediate, short-term and intermediate-term additional therapeutic effects of ultrasound-guided corticosteroid injection and dextrose injection of hyaluronic acid injection on patients with knee osteoarthritis, under the basis of International Classification of Functioning, Disability, and Health.
Knee osteoarthritis is a common condition characterized by pain and functional disability in older people. Prevalence increases with age and is more frequent in older women. The aim of this study was to assess the effects of an 8-weeks individualized comprehensive rehabilitation program with elastic bands on pain and functional disability in chronic knee osteoarthritis.
In vivo knee kinematics will be assessed for 20 subjects that have been implanted with either a MicroPort Medial Pivot or DePuy Attune posterior cruciate retaining (PCR) total knee arthroplasty (TKA) by Dr. Russell Nevins of Nevada Orthopedic & Spine Center [this is the location from which participants will be recruited].
Introduction: Quadriceps weakness was previously associated with functional impairment of osteoarthritis (OA). Evidence also suggests that muscle strength may prevent the progression of existing OA. It is estimated that the decline in muscle mass between 40 and 80 years is between 30% and 50%, with reported losses in functional capacity reaching 3% each year beyond the age of 60 years. Therefore, procedures capable of increasing the effects of exercise on muscle strength and function may be beneficial for elderly patients with knee OA. The results of our studies have shown that with each year of life the patient loses strength gain capacity. Objective: To evaluate if a multiprofessional educational program associated with BCAA and creatine supplementation improves the quality of life, function, pain and body composition of patients with OA and age greater than or equal to 70 years. METHODS: 34 patients with knee OA and age greater than or equal to 70 years will undergo an educational and physical training program lasting 20 weeks. Half of the patients will receive creatine (control) and the others will receive creatine and BCAA (study). Patients will be evaluated through functional tests (sit-up and 30-second tests and time up and go), standardized questionnaires (WOMAC and Lequesne), quality of life scales (Euroqol-EQ-5D-5L), pain (through VAS), body composition and bone density (through densitometry), and level of physical activity. All of the above parameters will be assessed at the beginning of the study and 6 and 12 months later. All project costs will be reported and a cost-effectiveness and cost-utility analysis will be performed. All project costs will be reported and a cost-effectiveness and cost-utility analysis will be performed.
The tripod of OA clinical treatment is education, weight loss and exercise. A sedentary lifestyle has been characterized as an independent risk factor for cardiovascular disease. Studies have shown the inverse association between the level of physical activity and the incidence of cardiovascular disease. High Intensity Interval Training (HIIT), which consists of repeated high-intensity exercise sessions interspersed with passive recovery. Active, has been studied as a new therapeutic approach and has been shown to be effective in controlling blood pressure (BP) and arterial stiffness in treated hypertensive individuals. HIIT training has also been shown to be able to reverse the hemodynamic, metabolic and hormonal changes that are involved in the pathophysiology of essential hypertension, leading to improved arterial stiffness and BP response, endothelin-1 and nitrite / nitrate to exercise, increased cardiorespiratory fitness when compared to moderate-intensity continuous exercise in young women with a family history of essential hypertension. Six weeks of HIIT training (3 times / week) reduced body fat and waist circumference in young women. , while increasing fat-free mass, maximum running speed and aerobic fitness. Two recent studies evaluating body weight change in overweight patients have shown that HIIT training is comparable to moderate-intensity continuous exercise, but HIIT is more efficient compared to time spent training, which may facilitate the inclusion of daily routine training of patients. Previous work performed by the authors patients undergoing an education and physical activity program showed improvement in WOMAC. The investigators believe that the inclusion of an HIIT training protocol may lead to improved BP and hemodynamic variables in patients with knee osteoarthritis. To evaluate the effect of high intensity interval physical training associated with an educational program on BP, hemodynamic variables of individuals undergoing treatment for knee OA. 63 patients with knee OA will be randomized into 3 groups: interval exercise (21), continuous exercise (21) and control (21). Patients will be evaluated for BP using ABPM, arterial stiffness and endothelial reactivity by measuring carotid-femoral pulse wave velocity and quality of life using the Euroqol scale.
Stromal vascular fraction of cells (SVF) will be extracted from lipoaspirate by enzymatic digestion. SVF will be administered in a single dose intraarticularly. All patients will receive cell therapy.This is a single arm study with no control.
Osteoarthritis is a common degenerative disorder of the articular cartilage . Risk factors include genetics, female sex, past trauma, advancing age, and obesity. The diagnosis is based on a history of joint pain worsened by movement, which can lead to disability in activities of daily living . Diagnosis of knee osteoarthritis can be confirmed based on clinical and/or radiological features. The potential of a progressive disease can be prevented or decreased by earlier recognition and correction of associated factors. Obesity and alignment especially varus malalignment are recognized factors of a progressive disease. High tibial osteotomy (HTO) is a widely performed procedure, and good results can be achieved with appropriate patient selection and precise surgical technique. It is reported to be an effective treatment for varus knee osteoarthritis (OA) by redistributing the load line within the knee joint . With an HTO, the surgeon aims to change the coronal alignment of the leg in order to shift the center of force passing axially through the knee from the arthritic region of the knee towards the unaffected side. The amount of alignment correction to be performed is calculated before surgery based on the extent of knee arthrosis and on the alignment of the patient's lower limbs on long-leg weight bearing radiographs . Our study is focused on effectiveness of open wedge High tibial osteotomy on clinical and radiographic outcomes of patients with medial knee osteoarthritis.
