Active clinical trials for "Osteoarthritis, Knee"

Participants diagnosed with tibial femoral knee osteoarthritis will be assigned to one of three treatment groups including: active transcutaneous electrical nerve stimulation (TENS), placebo TENS, and a control group. Assignment of conditions will be concealed. All participants in each of the three groups will receive physical therapy for all 4 weeks of the intervention. Main outcome measures will include quadriceps central activation ratio, quadriceps torque production, WOMAC scores, visual analog pain scores during gait as well as knee joint kinetics and kinematics during gait. The purpose of this study is to to determine if the continuous use of TENS therapy for activities of daily living and rehabilitation will positively impact all outcome measures.

The purpose of this study is to prove the non-inferiority of the intra-articular injection of hyaluronic acid (Sinovial®) in the symptomatic treatment of knee OA in comparison to Synvisc®.

Evaluation of the component position and kinematics after navigated and conventional Total Knee Arthroplasty.

Computer Aided Surgery in total knee arthroplasty improves knee stability and functional outcomes more than conventional total knee arthroplasty.

Primary Research Questions: Do patients with knee osteoarthritis (OA) who undergo total knee replacement with a Sigma rotating platform have better clinical outcomes at 2 years post surgery (i.e. quality of life, function, range of motion) than similar patients who undergo total knee arthroplasty (TKA) using the Sigma fixed bearing knee? Do patients with knee OA who undergo TKA with a Sigma rotating platform have different knee kinetics and kinematics as measured by gait analysis than similar patients who undergo TKA using the Sigma fixed bearing knee? Do patients with knee OA who undergo TKA with or without computer assistance have better clinical outcomes at two years following surgery (quality of life, function, range of motion)? Do patients with knee OA who undergo TKA with or without computer assistance have different knee kinematics and kinetics as measured by gait analysis?

To determine whether "continuous use" of celecoxib over a 6-month period is more efficacious than "usual or intermittent use" in preventing spontaneous osteoarthritis flares of the knee and hip.

The purpose of this study is to determine whether a home-based exercise and weight control program applied to elderly overweight individuals with painful osteoarthritis of the knee, would result in pain reduction.

This is a phase III, multicentre, randomized, double blind, parallel-group, pilot study designed to compare a long term (12 weeks) versus a short term (2 weeks) treatment with celecoxib 200 mg/die in treatment and prevention of new flare in patients with osteoarthritis of the knee.

This trial will test shoe inserts for the treatment of knee osteoarthritis, the most common form of knee arthritis. Those with disease on the inner (medial) aspect of the knee will be studied.

Knee osteoarthritis is a very common disorder affecting majority of elderly population. There is considerable functional disability associated with this disorder. The financial burden associated with this disease is quite high. Although various forms of pharmacologic and non pharmacologic therapies exist for its management, but most of these interventions only deal with symptoms without taking into account the associated factors aggravating the condition. Research suggests that abnormal loading of an arthritic joint will only increase the pain and disability. Participation in a regular exercise program involving weight bearing activities is a successful way to reduce or prevent decline in functional abilities. But the major problem with this approach lies in its abnormal loading of joint leading to altered biomechanics resulting in more joint damage. To counter this problem, lower body positive pressure or anti gravity treadmills have been designed. These treadmills provide up to 80% body weight support, thus considerably un-weighing the joint while retaining proper joint biomechanics. So with the help of this specialized training unit, elderly population will be better equipped to cope with arthritic changes leading to greater functional independence.
