Active clinical trials for "Osteoarthritis, Knee"

To our knowledge, there has been no information on in vivo clinical results of posterior cruciate-substituting arthroplasties using highly cross-linked polyethylene. We evaluated whether the clinical and radiographic results, incidence of post fracture of the tibial polyethylene insert, failure of the locking mechanism of the tibial polyethylene insert, and the incidence of osteolysis would be similar between posterior cruciate-substituting total knee prostheses using conventional and highly cross-linked polyethylene.

The purpose of the study is to evaluate the superiority of Rebel Reliever® knee brace + standard treatment versus standard treatment alone in terms of last 24-hour pain relief after 6 weeks. in patients with medial knee osteoarthritis.

Patients scheduled for total knee replacements and suitable for sciatic nerve block will be randomized to one of 2 groups. Group 1 will have the nerve block performed using a standard Pajunk block needle under ultrasound guidance and with electrical nerve stimulation (ENS), and have catheter placement also guided by electrical nerve stimulation. Group 2 will have the block performed using a Sonoplex echogenic block needle and have an echogenic catheter sited, all under ultrasound (US) guidance. Group 2 will have needle location aided by ENS, but ENS will not be used for catheter location. An observer blinded to the needle type will assess the quality of needle visualisation on a recording of the US image taken during the procedure, along with adequacy of spread of local anesthetic. The primary outcome will be needle visibility, and secondary outcomes will be block success rate, block performance time, complication rate, number of needle passes per block, and adequacy of spread of local anesthetic.

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

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.

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

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.

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.

The purpose of this study is to determine if the use of osteopathic manual therapy can influence the vascular supply to the knee, knee range of motion, balance and knee pain, in a group of subjects with knee osteoarthritis. It is also the objective of this study to determine if there is a difference between the osteopathic evaluation and the combination of an osteopathic evaluation and treatment.

The study will evaluate Apitox, pure honeybee venom as a treatment for pain and inflammation of osteoarthritis of the knee.
