safety and efficacy of Hyper Baric Oxygen (HBO) in patients presenting with spontaneous osteonecrosis of the knee
Femoral head avascular necrosis is a relatively common disease (10,000 - 20,000 yearly new United States of America cases) characterized by ischemic cell necrosis in a hip proximal epiphysis area frequently requiring total Hip Arthroplasty (THA). Even though THA resolves symptoms and restores good joint function, young patients are prone to major disabilities and require prosthesis revision surgeries. In this clinical trial a comparison between two groups of patients, treated with the same procedure but with two different regenerative techniques, will be performed: 1. 52 patients with necrosis in an early stage, without deformity of the femoral epiphysis (stage 2A-B-C in Association for Research on Osseous Circulation (ARCO) classification, will undergo wide decompression of the necrotic area and reconstruction with homologous Lyophilized Bone Chips (LBC), growth factors from platelet concentrate Platelet-Rich Fibrin (PRF) and Concentrated Bone Marrow (CBM). 2. 52 patients with necrosis of similar features, without deformity of the femoral epiphysis, will undergo wide decompression of the necrotic area and reconstruction with Demineralized Bone Matrix (DBM), growth factors from Platelet-Rich-Fibrin (PRF) and Concentrated Bone Marrow (CBM). Patients will be evaluated post-surgery at 6 weeks, 3, 6, 12, and 24 months to assess joint damage evolution by ARCO classification, and hip function by clinical scores (Harris Hip Score (HHS), Western Ontario and McMaster Universities Arthritis Index (WOMAC) Score, and Visual Analogic Scale (VAS)).
Bisphosphonates are drugs that prevent bone loss by blocking the activity of cells that normally resorb bone. The most common examples of these drugs are Boniva and Fosamax. These drugs are available for oral or intravenous dosing and are prescribed at daily, weekly, biweekly, or monthly intervals. Among the many thousands of individuals who currently take these medications, certain individuals experience "atypical" femur fractures preceded by prodromal pain, changes in cortical thickening of bone, or bisphosphonate related osteonecrosis of the jaws (BRONJ). Osteonecrosis of the jaws is defined as exposed bone of the jaws for 8 weeks or more and requires surgical treatment. This study will attempt to identify genomic and rna biomarkers that may play a role in differential metabolism of bisphosphonates or indicate tendency toward the severe adverse events associated with these drugs.
The purpose of this prospective, randomized study was to compare the clinical and radiographic results and the prevalence of osteolysis of the cementless total hip arthroplasty with an alumina-on-alumina bearings one side and alumina-on-highly cross-linked polyethylene bearings on the other side in the young and active patients.
This study will compare alignment criteria in the Oxford Partial Knee using conventional instrumentation and Signature Custom Guides in order to determine if the use of the Signature Custom Guides results in a higher percentage of knees achieving optimal alignment. The study will also examine outcomes with high volume surgeons (>30 cases/year) and low volume surgeons (<10 cases/year).
The purpose of this study is to analyze the safety and feasibility of direct administration intrafemoral mesenchymal stem cells (MSCs) in vitro expanded autologous treatment of patients with femoral osteonecrosis.
Osteonecrosis of the Jaw (ONJ) Case Registry
The purpose of this study is to investigate the efficacy and safety of autologous transplantation of Adipose Tissue derived Mesenchymal stem cells (MSCs) in patient with avascular necrosis of the femoral head.
The aim of this study is to evaluate the effects of an exercise program with a cycle ergometer in functional outcome and related-health quality of life (RHQL) in elderly patients with total hip arthroplasty.
