Active clinical trials for "Osteoarthritis, Knee"

: Total knee revision arthroplasty is increasing in daily practice and will become more relevant in the years to come. Bone loss is a significant challenge in total knee arthroplasty (TKA) especially in revision procedures. Metaphyseal sleeves are widely used to bypass bone loss and improve stability. This study aims to report the results of primary and revision TKA (R-TKA) using metaphyseal sleeves.

The aim of this study was to investigate whether exercise-induced hypoalgesia (EIH) is present following exercise in patient after total knee arthroplasty (TKA) and if so, if it changes with exercise intensity. A repeated measures and single-blinded randomized study were done. Thirty-eight patients 24 hours after TKA were randomly assigned to either low intensity exercises (LIE) group or high intensity exercises (HIE) group. An exercise programs lasted for five days during the hospitalization period. Pain severity was assessed by Visual Analog Scale (VAS) (0-10 mm). Pressure pain thresholds (PPTs) were measured over quadriceps and biceps brachii and muscles immediately before and after exercise.

Patients are randomized to receive pain control after Total Knee Arthroplasty with either a regional pain catheter or a local intraarticular pain catheter. Pain, analgetic use and mobility is asessed.

The investigators plan to undertake a rigorous multicentre randomised controlled trial, comparing acupuncture on sensitized acupoints with low/non-sensitive points or no acupuncture (waiting-list), to test if acupuncture on sensitized acupoints may result in improved treatment outcomes in patients with Knee osteoarthritis (KOA).The current pilot study aimed to assess the feasibility of performing the definitive randomised controlled trial.

To evaluate the lower limb alignment following total knee arthroplasty (TKA) performed with fully disposable patient-specific instrumentation versus conventional, versus patient specific instrumentation.

This study will show whether Tri-Vector method can ensure more extensive visual field and conduct the precise surgery when compared with Mini Mid-Vastus method by conducting 2 types of skin incision approach, Tri-Vector for 36 patients or Mini-Mid Vastus for 36 patients in Vanguard PS artificial knee joint total replacement observational period before and during surgery.

The goal of this study is to determine if the rotating platform high flex design provides improved flexion compared to the standard rotating platform TKA.

The purpose of this study is twofold: 1) to use RSA to determine the migration patterns of the PA coated Triathlon Total Knee Arthroplasty components during the first 2 years postoperatively and thus determine the proportion of cases where adequate fixation is achieved, and 2) to use DEXA scanning to document peri-prosthetic bone mineral density changes in response to the PA coated Triathlon Total Knee arthroplasty over the first two postoperative years. In addition, gait assessment and validated outcome questionnaires will be utilized to quantify changes in functional status of subjects after surgery and migration patterns will be compared to results obtained from previous studies of uncemented total knee arthroplasty components conducted at this centre. Questions to be asked are: 1. Do the components achieve adequate fixation to the underlying bone? 2. What are the migration patterns (translations and rotations) of the PA coated arthroplasty components during the first two years postoperatively and are they different from that seen for other implants that have been studied with RSA at this institution? 3. For what proportion of implants does migration continue to increase during the two year follow-up? 4. Are inducible displacements, measured at weight-bearing follow-ups, consistent over time and do they indicate that adequate fixation has been achieved? 5. Are there changes over time in bone mineral density of peri-prosthetic bone in the PA coated Triathlon total knee arthroplasty? 6: Where do changes in bone mineral density occur? 7: Is there a significant difference in health status and functional outcome before and after total knee arthroplasty using PA coated Triathlon total knee arthroplasty components? 8: Are there changes in gait symmetry and centre of mass (COM) displacements as assessed with the Walkabout Portable Gait Monitor pre- and post-operatively and how does study gait data compare to asymptomatic gait? and finally, Question 9: Are there differences in the micromotion patterns between the when compared to other samples of knee implants in our RSA database?

Different strategies of tourniquet application during elective primary total knee arthroplasty are thought to be associated with different outcomes. In that context, the study investigates different tactics in the search of optimal application of the tourniquet and the related fluid management during 24 perioperative hours.

PH-797804 is a potent inhibitor of inflammatory mediators that have a potential role in pain signalling following nerve injury and inflammation. Blocking such mediators may potentially have a therapeutic benefit by reducing pain.
