Comparison of High Flex and Standard Rotating Platform Total Knee Arthroplasty (TKA)

Knee Osteoarthritis

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.

Roentgen Stereophotogrammetric Analysis (RSA) and Dual Energy X-ray Absorptiometry (DEXA) to Evaluate...

OsteoarthritisKnee

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?

Local Anesthetic Infiltration and Infusion for Pain Control After Hip Replacement

Osteoarthritis

The purpose of this study is to examine three different ways to control pain after hip replacement: One time injection of ropivacaine before wound closure One time injection of ropivacaine before wound closure plus slow release of ropivacaine via catheter for 48 hours Standard practice of patient controlled pump

Comparison of Three Tourniquet Application Methods in Primary Total Knee Arthroplasty Surgery

Knee Osteoarthritis

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.

Clinical Trial to Examine the Pain Relief of PH-797804 Alone Or With Naproxen in Subjects With Osteoarthritis...

Osteoarthritis

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.

Prevention of Coronary Heart Disease in Morbidly Obese Patients

Morbid ObesityHypertension3 more

The changes in risks of developing coronary heart disease in patients with morbid obesity after different weight loss interventions have not been extensively studied. The primary objective of this study is to investigate whether an intensive lifestyle intervention program in a tertiary care clinic (Spesialsykehuset for Rehabilitering) is comparable with a 7-week low-energy-diet followed by bariatric surgery in decreasing the risk of cardiovascular disease in these patients.

Comparison of A Mobile-Bearing Total Knee System With A Fixed-Bearing Total Knee System In Cemented...

Degenerative Joint Disease

Pain, weakness, instability, and progressive dysfunction are the hallmarks of arthritis of the knee. Total knee replacement may frequently be the only therapeutic intervention to provide adequate improvement in pain and function. Both fixed bearing and mobile bearing knees have a long track record of clinical success. Mobile bearing designs have theoretical advantages of decreased contact stresses on the tibial tray, decreased polyethylene wear, and improved range of motion relative to fixed bearing designs. These theoretical advantages may become especially important in the young patient who requires a knee arthroplasty. This study will attempt to see if there is a clinical difference in outcome between mobile bearing and fixed bearing knee arthroplasties in patients who require total knee replacement.

A Study to Determine the Difference in Low Contact Stress (LCS) Duofix Versus Low LCS Porocoat Knee...

Osteoarthritis

The primary objective of this investigation is to test the hypothesis that the Duofix Tibial component results in a reduction of immediate postoperative pain compared to the LCS Porocoat version.
