Active clinical trials for "Osteoarthritis"

The hip prosthesis market is constantly growing with the number of prostheses reaching 949,000 in 2019. Along with this, there is also an increase in interest in short stems also called shortened stems. Thus on Pubmed, in 5 years, 171 publications have been listed. Thus, it seems interesting to study and analyze the performance of the shortened stem used in the Department of Orthopedic Surgery and Traumatology of the University Hospitals of Strasbourg and to compare them with the results of the literature.

Osteoarticular surgery is frequently associated with the occurrence of moderate to severe postoperative pain. This pain can persist and become chronic post-surgical pain that is often debilitating. The transition between early postoperative pain and chronic pain is poorly understood, which complicates treatment.

Relevance The first metatarsophalangeal joint (MPJ) has an important function in the biomechanics of human gait, especially in the toe and thrust phases, as the full range of motion at this joint provides the body with smooth horizontal acceleration. The flattening of the arches of the foot and, as a result, the overload of its anterior section occupy a leading place in the etiology of deforming osteoarthritis (Hallux rigidus). Hallux rigidus is a disease associated with degenerative changes in the articular cartilage of the first metatarsophalangeal joint. The relevance of the treatment of arthrosis of the first metatarsophalangeal joint is determined by the high incidence and functional significance of the joint. At the 3rd and 4th degrees of arthrosis, arthrodesis, resection arthroplasty and arthroplasty of the first metatarsophalangeal joint are used. To date, the most optimal methods of surgical treatment of severe arthrosis of the first metatarsophalangeal joint are arthroplasty and arthrodesis of the joint. These operations are preferred because they achieve good clinical and radiological results. Long-term follow-up studies are needed to confirm the current findings. Uncoupled endoprostheses are characterized by satisfactory mobility, the ability to withstand high loads, and ligament structures are preserved during their implantation. Of the existing types of non-bonded endoprostheses, zirconium ceramics has a number of advantages, such as: good ingrowth ability, no wear, no rejection reactions. The main advantages of this type of surgical treatment are: rapid pain relief, improved function and stability, individual adaptation of prostheses. Endoprosthetics is recommended for patients of working age with high functional demands. Thus, the development and implementation of new design solutions in clinical practice is relevant and promising. task in the surgical treatment of patients with deforming osteoarthritis of the first metatarsophalangeal joint. Purpose of the study: To develop and introduce into clinical practice a new method of surgical treatment of patients with deforming osteoarthrosis of the first metatarsophalangeal joint using an anatomically adapted endoprosthesis.

The primary working hypothesis of this study is whether wrist arthrodesis leads to an improvement in functional status in both rheumatoid arthritis and post-traumatic osteoarthritis. Functional status will be measured by Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire no earlier than 1 year after surgery.

Evaluate the correlation between altered glycometabolic status and joint inflammation in diabetic patients with osteoarthritis undergoing knee replacement surgery

The purpose of this study is to compare cemented and cementless versions of the Triathlon total knee arthroplasty/replacement (TKA) in terms of clinical outcomes, perioperative course, and outcome scores including function and patient satisfaction. Patients who present to the clinical practices of Dr. Ryan Nunley, Dr. Robert Barrack, or Dr. Denis Nam and are suitable candidates for primary TKA will be screened for eligibility and invited to participate. Once enrolled participants will be randomized (1:1) to either receive a cemented or cementless Triathlon TKA. Data collected for the study will include standard of care clinical and radiographic evaluations collected during office visits and surgery, as well as study-specific patient questionnaires. Clinical, radiographic and questionnaire data will be collected pre-operatively, at the time of surgery, and at 6 weeks, 6 months, 1 year and beyond, and 2 years and beyond post-operatively. Patients will complete the following outcomes questionnaires preoperatively: New Knee Society Score, Oxford Knee Score, UCLA Activity Score, SF-12, and EQ-5D. The following questionnaires will be collected at four to six weeks, six months, one year and beyond, and two years and beyond postoperatively: New Knee Society Score, Forgotten Joint Score, Washington University Knee Satisfaction and Function Questionnaire, Oxford Knee Score, UCLA Activity Score, SF-12, and EQ-5D, and a Pain Drawing. In addition, a Pain Diary with a pain Visual Analog Scale (VAS) will be assessed once daily at home for 6 weeks after surgery.

Generally, osteoarthris (OA) is considered as primarily cartilage disease. However, as we and others have previously reported, a portion of OA might be caused primarily by bone alterations. In this study, we prospectively and retrospectively show that the bone altertations may affect OA primarily in all of the joints. In addition, rheumatoid arthritis (RA) is a joint disease when immune system attacks synovium. Joint destruction occurrs continuously if suitable treatment is not performed. The etiology of RA is still largely unknown. As with OA, RA can be primarily damaged in bone, instead of cartilage. Here we prospectively and retrospectively show that the bone altertations may affect RA primarily in all of the joints.

The aim of this observational study is to collect clinical and radiological results of the new Plasmafit® Revision Structan® Hip Endoprosthesis Cup in a standard patient population and when used in routine clinical practice.

Patient-related outcomes were originally designed to measure outcomes in clinical studies. They were not developed to predict outcomes, however, different studies showed close association between values achieved preoperatively and postoperative outcomes. The aim of the present trial is to identify patients with satisfactory and unsatisfactory outcomes after joint replacement and to investigate whether there are any potential predicting potential in preoperative results of the patient-related outcomes and if there exist other predicting factors for functional recovery or treatment failure after joint replacement surgery.

The study aims to determine whether CMC I arthroplasty using a Touch® implant results in higher patient satisfaction compared to RSI arthroplasty in the medium-term in patients with primary thumb osteoarthritis. Additionally, the study compares the patients' clinical and self-reported outcomes between the Touch® implant and the RSI arthroplasty. Therefore, patients with a Touch® implant in one thumb and an RSI arthroplasty in the other thumb will be recruited.
