Active clinical trials for "Osteoarthritis"

Osteoarthritis (OA) affects aged above 45 years. RF has been used for several painful conditions. There have been a few attempts to use RF current for the treatment of painful conditions of joints of the extremities. It was also used for the treatment of painful conditions of the hip joint.

The purpose of this study is to evaluate the performance of the Agili-CTM implant in the treatment of osteoarthritis of the Great Toe.

In this study the investigators propose to monitor subjects who have received Triathlon total knee components inserted with HV cement. The primary outcome will be fixation of the tibial implant component as assessed with RSA and to determine the functionality of patients after surgery using self-reported questionnaires. This is a historical control study, comparing the study cohort to a previous group with Triathlon implants and the long-standing Simplex T cement. The secondary outcomes are inducible displacements of the implants as well as a qualitative evaluation of the cement handling characteristics performed by the operating room staff.

Comparison of two unicompartmental knee arthroplasties (UKA), to see if Sigma UKA performs equally good as the Oxford UKA. The study focuses on how well the arthroplasty is fixated to the bone and on the difference in wear of the plastic insert. Finally, the functional outcome after surgery is compared between the two arthroplasties. Hypothesis: H1: The Sigma UKA has an equal migration pattern compared to the Oxford UKA with a follow up of two years - that is, no significant difference in migration between 1-2 years follow-up. H2: The Oxford and Sigma UKA's have comparable polyethylene wear with a follow up of 5 years. H3: The Oxford and Sigma UKA's have comparable patient perceived outcome measures (PROM) and leg extension power (LEP) postoperative. H4: BMD of the proximal tibia does not influence migration of the tibial component

Randomized study comparing surgical and economic parameter of Total Knee Arthroplasty performed using two different specific surgical techniques.

Introduction: Investigators think that surgery with preservation of healthy joints (hemitrapeziectomy) in trapeziometacarpal osteoarthritis without affecting sapho-trapezo-trapezoid joints, is better for scaphoid stability by preventing its collapse and thus preserving the stability of the carpus. Objectives and Hypothesis: Ligamentoplasty with partial trapeziectomy in grades II-III Eaton presents better results in the pollicis-lateral pinch (key pinch) strength than ligamentoplasty with total trapeziectomy. Main Objective: To demonstrate using the dynamometer that the postoperative key pinch strength higher using ligamentoplasty with partial trapeziectomy in grades II-III Eaton. Secondary objectives: To measure the collapse of the first column of thumb using calibrated radiographic analysis. Pain (E.V.A Scale). Range of motion (measured with goniometer). Quality of life (DISABILITIES OF THE ARM, SHOULDER AND HAND questionnaire). Methodology: It is a single-center randomized trial, parallel-group, in which two types of surgical techniques (TT - TP) will be compared. Patients will be randomized in this two techniques will be followed for one year, in routine clinical practice.

The study design comprises a randomized trial of patients undergoing primary total hip arthroplasty using the G7 acetabular system and Taperloc Complete stem comparing regular plasma porous spray with HA coating using Bonemaster (BM) in an uncemented cup. DEXA scanning will be used to measure periprosthetic bone mineral density. Clinical evaluations will be conducted .

Ostearthritis is a great source of pain. In symptomatic hip the pain can lead the major disability and poor quality of life. Understand the musculoskeletal factores can lead to a better clinical management. The muscle strenghening of posterolateral complexo of hip is a important consideration. General Objective: Perform a Kinetic analysis 2D using na anterior wedge. Specific objective: Analyze the influence of posterolateral hip complex. Controlled clinical trial, composed by 30 individuals with and without osteoarthritis of hip e will be used a tools; Analogic Visual Scale, manual dynamometry to analyze force and kinetic analyze of gait through of Myovídeo analysis software.

The hypothesis of this study is that since osteoarthritis of the knee is primarily a bone disease where the joint changes are secondary, and bone growth stimulators function to decrease intraosseous venous congestion and remodel bone, then there is a potential benefit for the treatment of osteoarthritis of the knee with bone growth stimulators.

This study is a randomized controlled clinical trial using a blind evaluator. Fifty-one volunteers were selected from 50 years to 70 years, obeying the following criteria: diagnosis of knee OA grade II and III through the radiographic classification of Kellgreen and Lawrence 1955, Body mass index (BMI) less than 40 kg / m², volunteers should have had knee pain for at least six months. All are from the Rehabilitation Sector of Santa Casa de Misericórdia de São Paulo (ISCMSP). The subjects were evaluated through a questionnaire developed by the authors of the study (Annex I), the Visual Analogue Scale (EVA) (Annex II), then applied to the Lower Extremity Functional Scale LEFS (Appendix III) and the Activities of daily living scale ADLs (Annex IV). In addition, the evaluation of muscular strength was through dynamometry using the Lafayete dynamometer model 01163, which was performed by a blind evaluator regarding the group that will belong to each candidate. The muscles tested were: quadriceps, ischiostibial and gluteus maximus. The randomization was through 60 brown envelopes divided into A, B, C and D, designating the randomness of the sample. In addition to the initial evaluation, an evaluation was performed at the end of the tenth session and after 3 months of treatment. The volunteers underwent a five-week treatment program, totaling 10 sessions, divided into four groups, group A - Intervention (INT) underwent knee and hip muscle strengthening exercises and electromagnetic field therapy with (Meditea - ARG) using the coplanar technique, group B - Exercises (EXE) carried out exercises to strengthen the hip and knee muscles in the C - Placebo group (PLA). hip and knee and electromagnetic field therapy with the Magnetron® coplanar technique, but with the device switched off and group D - Apparatus (APA) only use electromagnetic field therapy with the magnetron® coplanar technique. In the present study, there were no significant differences between groups regarding pain, function and muscle strength. However, group A obtained better results in the evaluated criteria, tending that the combination PEMF and exercises, is an indicated treatment for OA knee.
