Filter by:The purpose of this study is to identify novel imaging markers for characterizing the biochemical profiles in synovial fluid and cartilage matrix in OA knee joints after intra-articular HA (Euflexxa) injection using high field NMR and MRI techniques. We hypothesize that: 1. High-field HRMAS NMR spectroscopy will provide sensitive measures for biochemical changes within knee synovial fluid after HA injection; 2. Baseline HRMAS spectroscopy, in particular N-acetyl peaks, as well as early changes of glutamate will predict patient response of pain relief after HA injection; 3. MR cartilage T1p and T2 quantifications will provide sensitive measures for biochemical changes within knee cartilage matrix after HA injection. Specifically cartilage T1p and T2 will decrease in patients who respond to the treatment, indicating potential beneficial effects of HA injection to cartilage preservation.
Limb length inequality is when a person has one leg that is longer than the other. This research will look at correcting limb length inequality in adults with knee or hip symptoms. This study will examine whether ways of measuring leg length inequality in the clinic are valid and reliable, determine whether foot posture (flat foot, normal, and high arch) is related to leg length inequality, and determine whether shoe lifts are a helpful treatment for leg length inequality and knee/hip symptoms.
The main objective is to assess the efficacy of a new formulation containing chondroitin sulfate and glucosamine sulfate (CS+GS) compared with placebo in patients with primary osteoarthritis of the knee.
The purpose of this study is to see if a single injection of Cingal into the knee provides safe relief of pain caused by osteoarthritis.
Background: Osteoarthritis (OA) is the most common joint disease that causes symptomatic health problems in the elderly population. For some patients with knee OA, total knee arthroplasty (TKA) may be the only option that offers the possibility of reestablishing the patient's life quality. Surgery of TKA usually takes place in a complete bloodless field established by a tourniquet around the thigh. The method aims to reduce blood loss and give the surgeon better visibility during the operation. The method is, however, not without side effects as patients often experience severe pain and swollen leg in the time after surgery. Furthermore, has the method shown decidedly muscle- and nerve damage followed by prolonged rehabilitation and reduced physical function. It is, however, possible to perform the operation without the use of the tourniquet. Aim and hypothesis: The aim of the present study is to assess the effects of tourniquet use in TKA on physical function, early rehabilitation, pain and opioid consumption. Hypotheses H1: TKA without tourniquet leads to better physical function and early rehabilitation. H2: TKA without tourniquet causes less pain and opioid consumption H3: Recovery of mechanical lower limb function post TKA is faster without use of tourniquet. Methods: 80 patients (40 in each group) all eligible for TKA will be consecutively recruited and randomized to A) TKA without tourniquet, B) TKA with tourniquet. Subjects will be evaluated before the operation (baseline) and 14 days, 3, 6 and 12 months after the operation. The primary outcome will be the change from baseline to 3 months in self-administered knee-function (KOOS-ADL subscale). Further, will we examine a number of pre-specified secondary outcomes, which include self-rated knee-related pain, symptoms, difficulty with sports and leisure activities, and quality of life. In addition, muscle function, physical performance, and the use of pain medication will be studied Impact of the project: The project design of this study will enable analyses for determining the impact of operating without tourniquet and whether such an intervention can in fact improve physical function, performance and quality of life within TKA patients. The results may impact notably on the patient level and possible redefine current surgical strategies. The societal perspective of the project is to remobilize patients faster, which may reduce hospital services and absence from work.
The primary objective of the study is to assess analgesic efficacy of Impracor (Ketoprofen 10% Cream) compared to placebo for acute pain associated with OA flare of the knee.
The aim of this study is to evaluate the effectiveness and safety of a combined Traumeel® / Zeel® injection against placebo (saline) in patients with moderate-to-severe pain associated with osteoarthritis of the knee.
Knee osteoarthritis (OA) is characterized by complaints of knee pain, aching and stiffness that commonly alter the way one will climb stairs and walk reducing an individual's function and the activities they may perform on a day-to-day basis. Providing a person with a knee brace designed for OA can help unload the arthritic part of the knee, thereby reducing pain and lead to improved function. The purpose of this study is to determine if use of the Rebel Reliever knee brace manufactured by Townsend Design can reduce pain and stiffness, improve strength and balance, and enhance functional activities such as stair and level gait, and ultimately lead to increased participation in the community.
The aim of this study is to confirm the biomechanical effects and evaluate functional benefits of a new knee brace combining valgus inducing effect on medial compartment and leg external rotation during the stance phase in patients with symptomatic medial knee osteoarthritis.
Articular cartilage can be the seat of many diseases including osteoarthritis and traumatic defaults. The cartilage has no intrinsic ability to repair resulting at long term in function loss in the joints. Currently available treatments are not satisfactory in the long term, the use of mesenchymal stem cells appears to be promising due to their ability to multipotency and immunomodulation properties. This project aims to determine the most appropriate source for regenerative medicine of cartilage stem cells from tissue taken during arthroplasty in patients with osteoarthritis. These cells will be tested for different chondrogenic markers. The success of this project will consider the implementation of a strategy for regenerative medicine in bone and joint diseases.
