Active clinical trials for "Osteoarthritis, Knee"

The results of the proposed experiments will directly inform clinicians who treat patients with osteoarthritis of the knee about how to maximize the benefits of acupuncture treatments. And because the experiments specifically asks the question of what is the relation between a patient's expectation of how a treatment will relieve their pain and the outcome of the treatment, the results will potentially inform care givers about all treatments for osteoarthritis and other chronic pain disorders. We hypothesize that acupuncture treatment will produce clinically significant analgesia as indicated by lowered sensory ratings of noxious stimuli and endogenous knee pain.

Weight is a risk factor for knee osteoarthritis Knee osteoarthritis is associated with abnormal gait biomechanics Gait biomechanics are evaluated in gastric bypass patients before and after losing 100 pounds.

International recommendations (ACR,EULAR) emphasize physical exercise and weight loss for patients suffering from knee osteoarthritis. Nevertheless, number of patients receiving advices for these 2 points still low. This study evaluates the impact of a standardized medical intervention (patient education, weight reduction and physical exercise) in knee osteoarthritis patients.

The aim of this study is to compare the cost-effectiveness of major joint replacement in patients with short and non-fixed (control group) waiting time (WT). After being placed on the waiting list, patients will be randomized into two groups through regular contact with the practice staff: (1) Patients with non-fixed waiting time (patient undergoes hospital's normal procedure from the date (s)he is added to the waiting list to the date of operation), and (2) patients with short waiting time (operated in maximum three months). The main question is: is it possible to improve the cost-effectiveness of major joint replacement by shortening waiting time?

the aim is to measure the level of adherence of knee osteoartheritis patients to a Carefully curated program that follows the American College of Rheumatology/Arthritis (ACR) recommendation guidelines and investigate the factor that might affect the patient's adherence to the prescribed protocol.

Total knee replacement (TKR) is accepted as treatment of choice for end stage gonarthrosis. It is performed cemented or cementless and although cemented implants were shown to decrease bone density more than cementless fixations there is no evidence-based difference between them in the literature. As far as the investigators are concerned, the effect of cementation on patients' joint perception has never been studied so far.

The purpose of the study is to gain a better understanding of how genetic variations can affect pain experience and the need and type of pain control medication after a total knee replacement.

Pain sensitization has been associated with pain severity in people with knee osteoarthritis (KOA) and a neuropathic pain component has been identified in up to 30% of KOA patients. In addition, exercise-induced hypoalgesia (EIH), a measure of descending pain control, has previously been found dysfunctional in a subgroup of people with painful KOA and has also been utilized as a predictive factor for pain progression following total knee replacement. Measures of pain sensitization have been used prognostic to identify responders to treatment but EIH as a prognostic tool for Physiotherapy-guided Evidence-based Exercise Therapy (PEET) has not been investigated. The primary aim of this explorative study is to investigate if EIH assessed pre-PEET was associated with changes in pain, disability and PainDETECT (PDQ) score post-PEET. The secondary aim is to investigate if PEET changes EIH and PDQ score in patients with painful KOA. Part 2: Cross-sectional studies indicate, that daily level of activity influence the effectivity of the EIH mechanims, while pain patients (e.g. KOA patients) can have normal of dysfunctional EIH. It has not been investigated if EIH changes after prolonged exercise in healthy subjects. The aim of this secord part of the study, is to investigate if EIH changes after 6-9 weeks of intensive military training in healthy subjects

This study compared the cost effectiveness of two-stage algorithm (prolotherapy injections (PrT) combined with rehabilitation protocol (RP) prior to total knee arthroplasty (TKA)) and one-stage algorithm (TKA) in the management of advanced stage knee osteoarthritis.

The purpose of this study is to compare the effects of the radiofrequency applied to the sensory innervation of the knee, with respect to a control group (standard therapy), in a prehabilitation program aiming to improve the functional recovery of patients undergoing TKA. In the present study, the investigators hypothesize that participants treated with radiofrequency 4-6 weeks before the surgery, should be able to effectively accomplish the prehabilitation program and, therefore, have a faster recovery of their functional status in the post operative period , compared with the control group (That use the present state of the art approach)
