Active clinical trials for "Osteoarthritis, Knee"

Objective: To study the feasibility and validity of a two-step telephone screening procedure for symptomatic knee and hip osteoarthritis (OA) in the general population. Method: The screening questionnaire was based on signs and symptoms, previous diagnosis of OA, and validated OA criteria. A random sample of telephone numbers was obtained and, at each number, one individual aged 40 to 75 years was included. A physical examination and knee or hip radiographs were offered when the screen was positive. A sample of individuals with negative screens was also examined. The diagnosis of hip/knee OA was based on either American College of Rheumatology criteria for signs and symptoms and Kellgren-Lawrence radiographic stage 2 or greater. Prevalence rates were estimated with correction for the performance of the screening procedure.

This is a multi-centered prospective, consecutively enrolled study that will be conducted in the United States. Surgeons that are new users of the iTotal Knee system (defined by no experience using the customized Total Knee Replacement (TKR) in the last 6 months) will be involved in the study. To complete the study protocol, the center will collect baseline surgical and training data on 10 "off-the-shelf" TKR patients using the implant system the surgeon currently uses. Then the first 50 consecutive patients who have been identified to receive the iTotal implant (Cruciate-Retaining or Posterior-Stabilizing) based on patient factors and the implant system IFU will be enrolled in the study. Simultaneous bilateral Total Knee Arthroplasty cases will be excluded.

This study will compare changes in outcomes following viscosupplementation for knee osteoarthritis.

This is an observation of the current use of a transdermal preparation of Celecoxib 8% which is being used in the treatment of patients with primary OA of the knees. Subjects will be followed for 12 weeks.

A functional outcomes comparison study of three surgical techniques using minimally invasive surgery mini-incision (MIS) for total knee arthroplasty (TKA), standard para-patellar TKA and the unicompartmental knee arthroplasty performed over a 2+ year post-op period.

The study is designed to evaluate and compare the efficacy of three needles approach as a new technique in radiofrequency neurotomy of genicular nerve versus the traditional single needle approach as a treatment of advanced knee osteoarthritic pain. Primary outcome: Pain intensity via the visual analogue score (VAS). Function and pain via the Oxford Knee Score. Evaluated after 6 months of the procedure Secondary outcome: Failure rate. Incidence of any complication. Total analgesic requirement during the period of follow up.

Background: Total knee arthroplasty (TKA) is one of the most common operations in orthopedics. After surgery, the decline of bone mineral density and muscle mass was proved, oral bisphosphonate is commonly used to prevent BMD loss in clinic treatment, however, the loss of muscle mass can only be maintained with exercise intervention. The goals of TKA rehabilitation should be based on control pain, improve ambulation, maximize the range of motion, develop muscle strength, and provide emotional support. We planned to find out a potential adjuvant effective option in muscle mass for the management of post-TKA. Literature suggested that exercise training has been found to have the considerable effect on TKA. However, no suitable exercise prescription was established on the scientific basis. The current study aimed to find out a potential treatment mode. Study Rationale: This project will be performed for consecutive three years, the patients with post-TKA patients are managed with the treadmill exercise training in the first year. In the second year, resistance exercise is prescribed. In the third year, eccentric exercise plus resistance training will be arranged in the exercise group. We will analyze the data of the three years and cross-comparative analysis. A prescription of exercise training, a period of 24 weeks each year, 3 times a week, for each 10 minutes warm-up, 40 minutes exercise training, and 10-minute cool down for exercise prescription Study Objectives: To investigate the effect of long-term exercise training, eccentric and resistance exercise on muscle mass in patients with total knee arthroplasty. To monitor the performance index included: physiological indices, muscle mass, ambulation and the quality of life index. Study Design Duration of Treatment: Total of 6-month exercise intervention in each year. The number of Planned Patients: 35 subjects in each control and exercise group in one year, the total of 210 subjects in three years. Investigational Product: Automated biochemistry analyzer, Biospace Inbody 7.20 Analysis of body composition instrumentation; Dual Energy X-ray Absorptiometer (DEXA), isokinetic muscle strength measurement, VICON to analysis ambulation, functional fitness, the questionnaire including SF-36, KOOS and VAS pain score. Endpoints: Data collection in pre-surgery, 3 months, 6 months, 9 months and 12 months after surgery.

To investigate the effect of dichloride on pain control of knee osteoarthritis and the relationship between pain relief and medicine adherence. To evaluate the pain relief rate of patients with different initial pain.

Osteoarthritis (OA) and osteoporosis (OP) affect large numbers of the population. Around 8 million people in the UK are affected by OA and over 300,000 people present with fragility fractures in the UK each year. High impact exercise has been shown to improve markers of bone health but the effect of this exercise on the cartilage is less well understood. A six month, one leg, exercise program based on hopping will be carried out by a group of post-menopausal women. Post-menopausal women are particularly at risk from OP and the research should give information on the feasibility of this type of exercise program in this age group and the effect on cartilage. Participants will be aged between 55 and 70 (at least five years post menopause) with no conditions that would limit their ability to complete the exercise program. To assess changes in participants' cartilage and bone properties they will be asked to attend several meetings at Loughborough University. Before and after the exercise program participants will have bone density scans and MRI scans of the knee joint. A subset (n=4) will undergo high resolution bone scans that can demonstrate changes in bone structure. The intervention is a home based exercise programme lasting approximately 10 minutes per day. Initially this will be individualised to each participant with the end goal being daily exercise sessions. The programme will last for six months with supervised sessions offered throughout the trial. Using an intervention affecting just one leg will allow the research team to use the other leg as a control. The research team hypothesise that in a population of post-menopausal women, a six month, unilateral exercise intervention will improve bone mineral density at the proximal femur with no negative effects on articular cartilage.

This study aims to examine whether tranexamic acid has an meaningful clinical effect on blood loss after high tibial osteotomy. This study design is a double-blind randomized controlled trial. The patients were randomly assigned to intervention or usual care groups. Intervention patients receive tranexamic acid 2g for 10 minutes just before surgery. Primary outcome is hemoglobin level preoperatively, postoperative 1 day, 2 days, 3 days, 2 weeks. Secondary outcome included hematocrit level, hemovac drainage, total blood loss, need for transfusion, deep vein thrombosis, Visual Analog Pain Scale, and wound complication.
