[Tc-99m]-RPI-087 as an Imaging Marker in Osteoarthritis of the Knee Compared to Healthy Volunteers...
HealthyOsteo Arthritis KneeThe main purpose of this study is to test the safety and tolerability of T-087. The study will enroll 6 healthy volunteers (HVs) and 6-18 subjects with KOA. All eligible subjects will receive an intravenous injection of the radioactive investigational product (ip) (T-087), followed by SPECT/CT imaging of the knees and blood tests and clinical assessments for safety monitoring. Healthy volunteers will also have their whole body imaged and have extra blood drawn to determine where T-087 goes in the body. These additional procedures will be done on the same day as the ip administration, and repeated the following day. All subjects will have a final follow-up phone call within 2- 3 business days following the ip administration.
Neurophysiological Mechanisms Involved in Knee Osteoarthritis
Knee OsteoarthritisChronic PainIntroduction: Total knee arthroplasty (TKA) is an effective intervention to relieve people with osteoarthritis (OA). Nevertheless, 15 to 30% of patients continue to experience severe pain following surgery. Recent data suggest that central nervous system (CNS) changes may play a role in OA pain and possibly explain why some patients have poorer clinical outcomes following TKA. Objectives: Our main objectives are to explore the relationship between OA pain and (1) the integrity of corticospinal system, (2) the efficacy of descending pain inhibition circuits. Methods: Fifty-two patients waiting for TKA will be recruited. The integrity of the corticospinal projections will be measured using transcranial magnetic stimulation (recruitment curve of the affected quadriceps femoris muscle) and the descending pain inhibition circuits (bulbospinal projections) will be assessed by a counter-irritation paradigm (i.e., conditioned pain modulation with immersion of the arm in painfully cold water). Diffuse tension imaging (DTI) will also be used to quantify the strength of these corticospinal and bulbospinal projections. Clinical outcomes will be evaluated before and after arthroplasty with a series of validated questionnaires such as the WOMAC Scale, the McGill Pain Questionnaire and the Brief Pain Inventory. These different neurophysiological and clinical measures will be taken before surgery, 6 months after surgery and 1 year post-surgery. Anticipated results: The investigators expect a moderate association between pain and the strength of the corticospinal and bulbospinal projections. Moreover, it is expected that there will be a moderate association between the strength of the corticospinal/bulbospinal projections and the clinical evolution of patients.
Combined Administration of Intravenous and Topical Tranexamic Acid in Total Knee Arthroplasty
Degenerative ArthritisThis prospective randomized controlled trial was conducted To compare the efficacy of TNA in terms of total blood loss and the allogenic transfusion rate among the three study groups; intravenous alone, combined intravenous and low dose topical TNA and combined intravenous and high dose topical TNA. To evaluate the safety of each regimen in view of deep vein thrombosis and venous thromboembolism.

Association of Transcutaneous Electrical Nerve Stimulation and Hypnosis
Limbs ArthrosisNon Arthrosic Limbs Arthralgia8 moreAt Saint-Antoine's hospital, in CETD a multidisciplinary team takes care of patients with chronic pain. Free-drug techniques are available to reduce their consumption of analgesics. This study is to assess the relief obtained by the simultaneous combination of these two techniques: transcutaneous electrical nerve stimulation and hypnosis.
Prospective Evaluation of Biomarkers Variability in Knee Prosthetic Surgery
Knee OsteoarthritisBone quality is an important factor influencing the outcome of total knee replacement (TKR) surgery. Therefore, assessing bone quality preoperatively could help the surgeon in the choice of the most appropriate prosthetic implant. The primary goal of this study is to measure serum and tissue levels of some proteins involved in bone remodelling.
Intra-Articular Autologous Bone Marrow Mesenchymal Stem Cells Transplantation to Treat Mild to Moderate...
OsteoarthritisOsteoarthritis is a progressively degenerative disease resulting in increasing pain, impairment and ultimately disability. While the available treatments seek to ameliorate pain or improve mobility, these treatments rarely modify the course of the disease, but rather attend to its consequences. For early stage osteoarthritis, treatment is largely limited to addressing the symptoms of inflammation with non-steroidal anti-inflammatory drugs (NSAIDs). These drugs do not stop the progression of the condition or regenerates damaged cartilage. This is a randomized and open labelled study aimed to determine the efficacy of intra-articular implantation of autologous bone marrow-derived mesenchymal stem cells in patients with mild to moderate osteoarthritis.

Total Knee Arthroplasty: Functional and Clinical Outcomes
Knee OsteoarthritisThe purpose of this study is to assess the differences in functional and patient reported outcomes between total knee replacement (TKA) implants. In addition, this work will examine the correlation between functional assessments and patient reported outcomes following surgery. All subjects will complete assessments preoperatively, 4-6 weeks following TKA and then one year following TKA. Subjects will complete a series of patient reported outcomes as well as a series of functional outcomes at each of the time points of interest. The analysis will include a repeated measures design to determine differences between groups across time as well as correlations between the functional and patient reported outcomes. This work will hopefully determine the importance of using objective functional outcomes following TKA as well as determining the need for patient assessments out to one year following surgery.
