Active clinical trials for "Osteoarthritis, Knee"

Total Knee Replacement (TKR) is an operation to help with the pain and decreased function that happens with end stage arthritis of the knee. This operation has been shown to be very successful at relieving pain and improving patient mobility; however, some studies have shown that up to 20% of TKR recipients are not happy with their knee replacement. All of the reasons why some patients are not pleased with the outcome of surgery are not known, but one of the possible causes is the way the implants are placed, or aligned, during surgery. Most TKRs are aligned in a fashion that the bones in the leg are completely straight after surgery. This is known as mechanically aligning a TKR. A different alignment method known as kinematic alignment respects the natural bow legged or knock kneed alignment of the patient. It is hoped that kinematically aligning a knee replacement will improve how the knee feels to the patient and therefore improve their satisfaction. Another potential factor affecting the outcomes of TKR is obtaining optimal soft tissue balance. The challenge with balancing a TKR is that traditional operative techniques rely on subjective feel of the knee stability during surgery. The balance or tension in the knee can however be objectively measured using specialized intraoperative pressure sensing devices. The purpose of this study is to assess the impact of kinematically aligned TKR on the pressures measured by Verasense during total knee replacements. The study will also determine if differences in the pressure measured during TKR surgery impact patient outcomes after surgery.

The purpose of this study is to evaluate the efficacy and safety of intraarticular Invossa K Injection patients diagnosed with Kellgren & Lawrence grade 2 knee osteoarthritis.

The purpose of this prospective study is to examine the effect of two local anesthetics used in adductor canal blocks, with relation to pain, analgesic consumption, mobility, and pain related interference with activities and hospital length of stay. The two agents are bupivacaine and ropivacaine. The purpose of this trial is to examine the effect of these drugs being used in adductor canal blocks for pain relief, analgesic consumption, mobility, and pain related interference with activities and hospital length of stay.

The aim of this study is to investigate, whether a patient education with focus on pain coping is able to improve physical function and experienced pain level in patients with high levels of pain catastrophizing before Total Knee Arthroplasty. Resent studies indicates that these patients do not achieve a satisfactory pain relief and physical function after TKA. Furthermore, the aim is to determine if there is a difference in physical activity and muscle mass among patients with high levels of pain catastrophizing compared to patients with low levels of pain catastrophizing.

Using double blind, randomized controlled design to study the immediate, short-term and intermediate-term therapeutic effects of ultrasound guided hyaluronic acid injection and hyaluronic acid combined corticosteroid injection to patients with knee osteoarthritis.

This clinical research study will assess pharmacokinetics and the safety of Imrecoxib in patients with impaired hepatic function as compared to healthy volunteers.

The purpose of this study is to compare the effect of single adductor-canal-block versus single femoral nerve block on the recovery after total knee arthroplasty.

Individuals with painful knee osteoarthritis (OA) experience restricted physical function. Few previous studies have investigated comprehensive sets of constructs and tests to investigate physical function in these patients. Most single studies of knee OA patients show limited scope for explaining physical function in the perspective of WHO's International Classification of Functioning, Disability and Health (ICF) 3 levels: Body functions (the bodily level), Activities (individual level), and Participation (societal level). On the bodily level there is limited case-control knowledge on muscle strength beyond the knee and endurance-strength in general. On the activity level, there is similar limitation of biomechanical bodily features in stair climbing. On the participation level the situation is similar for objective performance. Measures are needed that inter-relate all three levels of ICF. These should also include well discriminating tests e.g. knee strength, walking, and activities of daily life (ADL), as well as both objective and subjective measures. The purpose of this study is to explore mechanisms that can explain physical function in patients with knee OA in primary care. The study's main and primary goal is to quantify which baseline factors and change scores are the strongest predictors of a positive treatment outcome in terms of patients' global perceived change after physiotherapy. Secondary research question is: which factors are the strongest predictors of a positive outcome of physiotherapy in knee OA, in terms of pain intensity, patient specific functional scale, and function in daily living?

Post-operative bleeding in total knee arthroplasty (TKA) can result in hypovolemic shock and unnecessity for allogenic blood transfusions. Intravenous and topical tranexamic acid (TXA) have been well established in reducing blood loss postoperatively. However, there are lack of data on peri-articular TXA injection during TKA. Therefore, the investigators conducted a three-arm prospective, randomized, controlled trial to compare the effectiveness of bleeding reduction of peri-articular TXA injections, intraarticular TXA injections and control group.

In this study, the investigators wondered whether the association between high frequency repetitive transcranial magnetic stimulation (hf-rTMS) and manual therapy (peripheral and central approach) is more effective in reducing pain levels and modulation of cortical activity of chronic knee ostearthritis pain subjects than manual therapy alone (usual peripheral approach). For this purpose, patients included will be submitted to one session with active or sham hf-rTMS followed by a protocol of manual therapy. Besides that another active group will have the sequence of interventions exchanged (manual therapy followed by hf-rTMS) in order to investigate whether this may influence in the final outcomes.
