Adipose-derived MSCs After Enzymatic Digestion vs. Mechanically Fragmented Fat Transfer in Knee...
Knee OsteoarthritisChondropathyThe aim of the study is to compare the clinical effects of treatment of knee osteoarthritis using adipose tissue mesenchymal stromal cells obtained by an enzymatic method with the outcomes of the therapy with the mechanically fragmented adipose tissue. Identification and functional analysis of the regenerative capacity of MSCs derived from the adipose tissue depending on three variables (body weight, sex and age) will help to develop a targeted therapy for different groups of patients and will determine the effectiveness of both methods of treatment. An attempt was made to identify the groups of patients with the greatest regeneration potential of the adipose tissue, and thus indicate those with the most probable improvement of the joint condition.
TAR 2 Weeks vs 6 Weeks Post-Operative Weight-Bearing
Ankle OsteoarthritisThe Investigators hypothesize that an early 2 week post-operative protocol will have no difference in the successful osseointegration and stability of the total ankle replacement as compared to a delayed 6 week post-operative protocol. The importance of the research is to allow patients who receive a total ankle replacement to bear weight 4 weeks earlier than the current protocol with no negative effect on the osseointegration and stability of the ankle replacement.
Effects of ASC Secretome on Human Osteochondral Explants
OsteoarthritisSince the need of finding effective disease-modifying anti-osteoarthritis (OA) treatments is still unmet, with this study the investigators aim to gather further evidences of the therapeutic potential of Mesenchymal Stem/stromal Cell (MSC) secretome in order to pave the way to its future use as a cell-free biological product. In detail, the investigators predict to validate the promising results obtained in vitro, ex vivo on osteochondral explants, an OA model more representative of the physiological situation.
Clinical and Functional Outcome of the GEMINI SL Fixed Bearing PS Knee Prosthesis
Osteoarthrosis of KneeThis is a prospective, multicenter, observational study with a planned follow-up period of 10 years to confirm the safety and performance of the GEMINI SL Fixed Bearing PS knee prosthesis in longterm follow-up under routine conditions. Primary outcome of the study is the 10-year survival rate of the GEMINI SL Fixed Bearing PS knee prosthesis with revision for any reason as the endpoint.
A Prospective Cohort Study of Patients Suffering From Hand Osteoarthritis Symptoms
Hand OsteoarthritisThe late-stage forms of degenerative osteoarthritis (OA) are very debilitating and less affordable to therapy. The main objective is to identify early onset symptoms of hand OA patients through imaging techniques (such as ultrasound and MRI). Our primary endpoint is to specify patients with high risk of radiological profression (X-ray).
Predicting Outcome of Total Knee Replacement Surgery in Patients With Knee Osteoarthritis
OsteoarthritisKnee3 moreOsteoarthritis (OA) is the main cause of pain and disability in elderly. For knee OA, a total knee replacement (TKR) is an effective surgical treatment, and the majority of patients report substantial pain relief and functional improvement following surgery. However, 20-40% of patients undergoing TKR are dissatisfied with postsurgical outcome. Even after revision, some patients keep complaining of persisting pain. In this study, the investigators will examine putative prognostic factors on the basis of the biopsychosocial model. Besides several psychological factors (measured with questionnaires), the investigators will assess structural impairments (such as radiographic severity of OA), functional impairments (muscle weakness and proprioceptive deficits), anesthetic procedures, immediate postoperative pain management, metabolic factors (body composition and hemoglobin A1c), inflammatory factors (C-Reactive Protein) and the investigators also will examine the role of altered central pain processing (CPP) (primary and secondary mechanical hyperalgesia, mechanical temporal summation, thermal primary and secondary hyperalgesia, endogenous pain modulation). With a longitudinal study design, this study will explore which factors are predictive of poor outcome in knee OA patients after TKR. Moreover, the interrelationship between CPP, structural, functional, metabolic, inflammatory and psychological factors, and the clinical expression of knee OA (pain, symptoms, physical performance and quality of life) will be investigated. Further research on the role of the aforementioned putative prognostic factors on postsurgical outcome could contribute to better management of these patients, since these factors may be particularly important for patient-tailored treatment.
Thromboxane A2 and Osteoarthritis
OsteoarthritisTXA2 inhibits the expression of the primary marker of thermogenesis (UCP1) while prostacyclin (PGI2), another metabolite derived from arachidonic acid, enhances its expression. Given the close relationship between the adipocyte and the chondrocyte, the study team hypothesises that thromboxane A2 controls chondrocyte formation and function and thus cartilage homeostasis. The study objectives are: i) to analyse the role of TXA2 on chondrocyte differentiation in vitro, ii) to determine the association between circulating and tissue TXA2 levels in a rat model of osteoarthritis, and iii) to correlate circulating and synovial fluid levels of TXA2 with the development of osteoarthritis in a small human cohort. The proposed research aims to better understand the mechanisms underlying the role of lipid metabolites in chondrocyte formation and function, paving the way for the development of nutritional and pharmacological therapies to combat OA and associated metabolic disorders.
A Study to Evaluate the Efficacy, Safety and Tolerability of EVI-01 Intra-Articular Injection in...
OsteoarthritisOsteoarthritis1 moreObjective: Identifying the dose of EVI-01 with the best clinical response, balancing the efficacy, safety, and tolerability of the investigational product. Study design: Interventional, dose-finding, three arms, randomized (1:1:1), parallel assignment, double-blind, controlled by an active comparator.
PMCF Study on the Safety, Performance and Clinical Benefits Data of the Anatomical Shoulder 2.0...
Proximal Humerus FracturePosttraumatic Arthrosis After Humeral Head Fracture1 moreThe study is a multicenter, retrospective and prospective, non-randomized, non-controlled and consecutive series post-market study. The purpose of this study is to collect long-term data confirming safety, performance and clinical benefits of the Anatomical Shoulder 2.0 Fracture System (Implants and Instrumentation) when used for fracture shoulder arthroplasty. The primary objective is the assessment of safety by analyzing implant survivorship. This will be established by recording the incidence and frequency of revisions, complications and adverse events. Relation of the events to implant, instrumentation and/or procedure should be specified. The secondary objective is the assessment of performance and clinical benefits by recording patient-reported clinical outcome measures (PROMs) as well as radiographic outcomes.
