9 Clinical Trials for Various Conditions
The primary objective of this investigation is to compare the precision of long leg alignment achieved by the two types of procedure. The secondary objectives of this investigation are to: Compare the accuracy of long leg alignment achieved by the two types of procedure. Compare the number of optimal implantations achieved by the two types of procedure. Compare the clinical performance of the knee replacement in subjects who have undergone one of the two types of procedure. Compare the functional outcome achieved by subjects who have undergone one of the two types of procedure. Compare the interface radiographic appearance 5 years post-operatively between the two types of procedure. Compare the accuracy and precision of long leg alignment achieved by the two types of procedure 5 years post-operatively, i.e., at final follow-up and also the change in accuracy and precision between the final follow-up and baseline. Compare the Adverse Events experienced by the subjects who have undergone the two types of procedure.
The purpose of this study is to evaluate and compare the clinical, radiographic (x-ray) and cost effectiveness outcomes (cost relative to risks and benefits) of two different minimally invasive knee joint replacement surgical techniques. The primary study hypothesis is that in comparing total knee replacement performed with the two different surgical techniques that respect four minimally invasive surgery principles (low-profile instrumentation, "minimally invasive" incision, overall minimal knee surgical intervention), a faster return to function will result when the technique does not incise the tendon.
This study will evaluate the benefits of continuing celecoxib through six weeks of total knee arthroplasty recovery. This is a randomized, double blind study with a group of approximately 130 primary total knee patients. All patients will receive celecoxib throughout their hospitalization as per current minimally invasive total knee arthroplasty protocol. At the time of hospital discharge, participating patients will be randomly placed on either celecoxib 200mg twice a day or a placebo twice a day. This study will determine if the continued use of celecoxib for six weeks after total knee arthroplasty hospitalization will further decrease narcotic consumption, improve knee range of motion, improve ambulatory ability, and improve patient satisfaction over patients receiving celecoxib only during the acute hospitalization.
Osteoarthritis (OA) is a long-term degenerative joint disease that disables about 10% of people over the age of 60 and compromises the quality of life of more than 20 million Americans. A procedure called total knee arthroplasty (TKA), in which the affected surface of the knee joint is replaced by plastic or metal, has been successful in restoring comfort and mobility to formerly arthritic joints. This study will compare quadriceps muscle strength, knee range of motion, and pain in people who have had a traditional TKA with those who have had a minimally invasive TKA.
The purpose of this study is to look at two different referencing systems for total knee replacement surgery. In anterior referencing system, referencing cuts are made from the front surface of the femur. This allows for a more exact cut. The anterior referencing system is more difficult for the surgeon to use. This may increase surgery time. Posterior referencing, on the other hand, references cuts from the back of the femur. The posterior referencing system is quick and easy for the surgeon to use. Posterior referencing may lead to notching of the femur. The risk of notching is very low and may not affect your results. This is a study that has never been done before. Dr. Heekin uses both referencing systems in his practice. He would like to determine which knee referencing system allows for greater knee flexion after surgery. Knee flexion correlates with function and the ability to return to everyday activities. For example, getting up from a chair, going up and down stairs, stooping, and kneeling.
The purpose of this study is to compare two different surgical approaches for total knee replacement surgery. The mini-midvastus approach involves cutting less of the thigh muscle (quadriceps) tendon than the classic approach (median parapatellar) in order to implant the knee components. Both will have the same skin incision.
The purpose of this study was to compare the early clinical outcomes of minimally invasive bilateral subvastus and midvastus approaches for total knee arthroplasty.
The hypothesis of the proposed study is that performing total knee arthroplasty through a mini subvastus approach results in statistically significant differences in one or more of the above functional outcome measures, when compared in a blinded, prospective, controlled, randomized manner to mini-medial arthrotomy approach. 1. Analyses of lower extremity functional activities (gait and stairs) 2. Strength of thigh musculature 3. Self-assessment of the functional outcomes 4. Return to the activities of daily living and sports activities
The functional flexion axis of the knee can be established by computer-assisted intra-operative data, through range of motion techniques, not specific landmarks such as epicondyles.
