Active clinical trials for "Osteoarthritis, Hip"

A study to translate and cross-culturally adapt the Intermittent and Constant Osteoarthritis Pain (ICOAP) measurement tool into the Arabic language, and assess its psychometric properties.

The purpose of the present study was to determine whether unilaterally operated total hip arthroplasty (THA) patients were superior to bilaterally operated THA patients with respect to aerobic endurance capacity, muscle strength and gait patterns 3-5 years after surgery, and to what extent medial femoral head offset (FO) influenced hip abductor strength.

Leg length discrepancies following total hip arthroplasty have been associated with nerve palsies, gait abnormalities, and lower back pain. Leg length discrepancies are related to poorer functional outcomes and patient dissatisfaction. Failure to restore femoral offset following total hip arthroplasty has been linked to decreased range of motion and abductor muscle strength, impingement, limping, higher dislocation rates, increased polyethylene wear, and loosening of implants. Computer navigation has shown to improve the accuracy of leg length and hip offset during total hip arthroplasty. The investigators research objective is to prove the accuracy of the Intellijoint HIP™ system for determining leg length and hip offset. The investigators hypothesis was that Intellijoint HIP™, an imageless intraoperative intelligent instrument, could improve the accuracy of leg length and hip offset during primary total hip arthroplasty. The investigators plan to study this hypothesis in humans by comparing the leg length and hip offset discrepancies produced with Intellijoint HIP™ to the standard at the investigators institution, which is a pin and outrigger system.

In total hip arthroplasty (THA), radiographic preoperative planning and postoperative evaluation of acetabular component, femoral offset (FO) and leg length discrepancy (LLD) require good validity, interobserver reliability and intraobserver reproducibility. Questions/purposes: (1) Evaluate the validity of the Sundsvall method of FO measurement by comparing it to a standard FO measurement method. (2) Evaluate the interobserver reliability and intraobserver reproducibility of measurement of FO, LLD, acetabular cup inclination and anteversion. 90 patients with primary unilateral osteoarthritis (OA) were included in this prospective study. On postoperative radiographs FO by the Sundsvall method, FO by a standard method, LLD, acetabular cup inclination and anteversion were measured. The interobserver reliability and intraobserver reproducibility were made by three independent observers. The validity and degree of prediction of Sundsvall method are measured by comparing its results with the standard method.

The study will evaluate the radiographs (x-rays) of 100 patients with a TriFIT total hip at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery to see if there has been any movement or wear in the hip stem over the course of the study. The study will also record clinical data on each patient using various functional tests and questionnaires at the same intervals.

This project is designed to use MRI to evaluate pre- and post-arthroplasty hips; the specific aims of this project are three-fold. First, the investigators intend to compare the amount of muscle atrophy and tendon damage that occurs around the hip between two commonly-used operative approaches: the direct-anterior approach and the posterior approach. Second, the investigators aim to provide baseline data on the amount of muscle atrophy and tendon damage that should reasonably be expected to occur with both of these approaches. Third, the investigators will document the degree of recovery of the periprosthetic soft tissues post-surgery in both patient groups. The investigators first hypothesis is that the posterior approach will demonstrate significantly more damage to the abductors, piriformis, and short external rotators than the direct anterior approach, which will demonstrate minimal soft tissue damage. The investigators second hypothesis is that both surgical approaches will cause some degree of baseline muscle damage and atrophy, in a predictable pattern. The investigators third hypothesis is that each of the surgical approaches inherently cause some degree of soft tissue damage, and that the periprosthetic soft tissues that are incised during the surgical exposure will recover in a predictable pattern which is consistent but unique within each group

Hypothesis: The spa therapy treatment could improve health-related quality of life (HRQOL) in subjects with knee and/or hip osteoarthritis, and patients with rheumatoid arthritis. Main objective: Analyze if HRQOL in patients with knee and/or hip osteoarthritis, and patients with rheumatoid arthritis is modified by spa therapy treatment in the spa of Fitero (Spain). Design: Prospective observational study Participants: Fitero's spa users aged between 45-80 years old, diagnosed with knee and/or hip osteoarthritis, and also with rheumatoid arthritis. At least 40 patients of each type will be included in the study. Participants must be receiving a treatment of at least ten days. Main Variable: The scores obtained in the Euroqol5Dimensions-5Levels questionnaire (EQ-5D-5L) (for all subjects), the Western Ontario MacMaster Universities Osteoarthritis Index (WOMAC) questionnaire, for subjects with knee and/or hip osteoarthritis, and the Health Assessment Questionnaire (HAQ), for subjects with rheumatoid arthritis. Other variables: sociodemographic, anthropometric, clinics, and related with spa treatment. Follow-up duration: 9 months.

The study aims to assess the clinical and radiographic outcomes of DELTA ST-C in combination with MINIMA stem at 3 years after primary THA surgery, and to evaluate the overall survivorship of the implant.

To assess the prognostic value of a characteristic evaluation of gait in persons suffering from hip OA for subsequent indications for THR.

The aim of the project is to assemble and to follow on a 10-year period a nationwide representative sample of lower limb OA patients. General objectives: To document the natural history and to identify predictive factors of the evolution and consequences of hip and knee OA in terms of pain, functional disability, structural damage, quality of life, autonomy, medical and health care use and cost of disease.
