Active clinical trials for "Osteoarthritis, Knee"

It is stated that after arthroplasty surgery, besides the physiological factors, the factors related to the individuals may affect the recovery. Among these factors, one of the most defined in the literature is kinesiophobia. Although kinesiophobia is defined as the terms of "fear of movement" and "fear related to pain"; There are also definitions for situations in which fear of movement is most extreme or pain-related fear avoidance beliefs. Kinesiophobia, which usually occurs in the preoperative period and supports the development of chronic pain, may also affect the early recovery findings. It is very important to determine the presence and severity of kinesiophobia as it is associated with functional results after surgery. Individuals' perceptions about themselves, expectations of recovery, and personal beliefs before surgery are thought to affect recovery in the early period. In the studies conducted, it was stated that individuals with high perception about himself and the surgical process recover faster and return to activities. However, it is emphasized that studies should be conducted on the effect of individuals' personal factors such as self-efficacy, self-perception and their perspective on health on the healing process.

The purpose of this study is to measure the changes in the medial and lateral meniscus extrusion of the knee joint before and after surgery using ultrasound in patients who undergo medial opening wedge high tibial osteotomy, and examine the differences.

The purpose of the study is a scientific and prospective documentation of the clinical effects of an inpatient treatment at the Immanuel Hospital of Berlin, in the department for complementary and integrative medicine, with the use of a modified fasting regime. A pre- and post- as well as group comparisons are planned. Patients that are admitted to the inpatient department for metabolic syndrome, osteoarthritis of the hip or knee, rheumatoid arthritis and fibromyalgia will be enrolled in the study.

This is a pilot diagnostic accuracy study conducted to assess the diagnostic ability of a novel APD for auricular point detection among patients with knee osteoarthritis (KOA), as compared with an already commercialized device.

This project aims to assess two different techniques used to position the knee replacement implant during surgery. The patients will be randomised to receive either the following: The established Navigation System (gold standard) The new Prophecy Technique (validated by the Navigation System) The study hypothesis is there will be no difference between the gold standard Navigation system and the Prophecy technique in relation to the placement of the knee implant.

The primary goal is to evaluate ropivacaine blood concentrations during and after local anaesthetic (ropivacaine) infiltration - the Caledonian technique - for total knee replacement surgery. The investigators plan to measure these levels by testing blood samples taken over a timed period. This will allow us to confirm whether the current regimen of local anaesthetic use is within safe limits.

Osteoarthritis (OA) is already one of the most disabling diseases in developed countries. Intra-articular (IA) injection of opioid in joints has been widely studied for its simplicity, safety and efficacy. We suggest the method of opioid patch regional application to OA patients instead of intra-articular opioid injections. We had applied buprenorphine patch to painful knee joint in knee OA patients, and compared knee application with conventional chest application for analgesic effects, adverse effects and compliance of buprenorphine patch. We willl retrospectively enroll about 200 patients with knee OA who did not respond to conventional therapy. Numeric rating scale (NRS), adverse effects, and compliance were checked and recorded before and after buprenorphine patch applied. All parameters were compared between chest applied group and knee applied group.

Patients referred to Calgary's Alberta Hip & Knee Clinic, while awaiting consultation with an orthopedic surgeon for hip or knee osteoarthritis, will be offered the opportunity to participate in a dietary counseling program with the goal of attaining weight loss prior to surgery. Those patients interested in participating in the program will be offered the opportunity to participate in the research trial.

Recently there has been a growing interest in the role of subchondral bone in knee arthritis, both in its etiology and evolution and in its clinical significance. It has now been widely demonstrated that changes in the subchondral bone can develop both as a cause and as a consequence of joint degeneration and it is now accepted in the scientific community that the presence of these changes is of clinical importance, causing pain and an inflammatory state that can contribute to the evolution of arthrosis arthropathy. Recently the use of mesenchymal cells obtained from the bone marrow has been proposed for the treatment of gonarthrosis by intra-articular injections. Even more recently, treatments have been studied and proposed for the treatment of the bone-cartilage interface in knees affected by osteoarthrosis, using autologous bone marrow concentrate, with promising results.

Every medical intervention requires informed consent. Informed consent may include comprehensible information about the necessity and kind of the intervention, material risks and consequences or alternative treatments. Practitioners frequently use consent forms to support the physician-patient conversation and to document informed consent. Studies show, that informed consent forms used in practice, are heterogeneous. This study aims at investigating the effects of evidence-based informed consent forms for Total Knee Replacement and related anaesthesia procedures. Evidence-based informed consent forms include best and latest evidence in lay language. It is hypothesized that evidence-based informed consent forms - compared to standard consent forms - improve patients' risk perception, reduce anxiety of complications and reduce the nocebo effect (unspecific negative effects caused by the way of communicating risks). To compare evidence-based and standard informed consent forms, an Interrupted Time Series pilot study will be conducted. It is planned to include 220 patients, who are scheduled for elective total knee replacement surgery. The accompanying qualitative analyses ensure that the (German) legal requirements for informed consent are met.
