Filter by:This surgery involves the use of a finger joint replacement device for treatment of patients with certain kinds of arthritis (osteo - arthritis or post traumatic arthritis) and who expect to place their hands in heavy loading situations, or patients needing revision of a failed implant placed in the PIP joint. A joint replacement surgery is an operation where the arthritic joint is removed and a metal and plastic joint is inserted to replace the natural joint. The surgery is expected to last about 2 hours. The procedure is done in the operating room and requires general anesthesia or an axillary block. (General anesthesia affects the entire body and is accompanied by a loss of consciousness. An axillary block results in anesthesia of the hand and forearm only. A tourniquet is applied to the arm to prevent bleeding during the surgery.)
The purpose of the study is to evaluate the efficacy of local infiltration of liposomal bupivacaine versus use of an indwelling femoral peripheral nerve block in controlling early postoperative pain in primary total knee arthroplasty. The investigators hope to demonstrate equivalency of treatment modalities to provide an alternative to the commonly used treatment of femoral nerve blockade.
This study evaluates the pathophysiological effects of a single dose methylprednisolone administered prior to total knee-arthroplasty surgery (TKA). The investigators examine the effect on the endothelial glycocalyx shedding due to surgical trauma. Half of participants will receive intravenous Solu-Medrol 125 mg, while the other half will receive placebo. The investigators hypothesize that the group receiving methylprednisolone will experience reduction in glycocalyx degradation compared to the placebo-group, early after TKA.
This study evaluates the pathophysiological effects of a single dose of methylprednisolone administered prior to total knee-arthroplasty surgery. The investigators examine the effect on complement activation. Half of participants will receive intravenous Solu-Medrol 125 mg, while the other half will receive placebo. The investigators hypothesize that the group receiving methylprednisolone will experience beneficial inhibition of the undesirable parts of the complement activation.
This study evaluates the pathophysiological effects of a single dose of Methylprednisolone administered prior to total hip- and knee-arthroplasty surgery. The investigators examine the effect on blood glucose homeostasis. Half of participants will receive intravenous Solu-Medrol 125 mg, while the other half will receive placebo. The investigators hypothesize that the glucose homeostasis remains equally stable in the group receiving Methylprednisolone as in the group receiving placebo.
This study evaluates the pathophysiological effects of a single dose Methylprednisolone administered prior to total knee-arthroplasty (TKA). The investigators examine the effect on thigh muscle function to evaluate the efficacy of Methylprednisolone on knee-extension strength at discharge after TKA. Half of participants will receive intravenous Solu-Medrol 125 mg, while the other half will receive placebo. The investigators hypothesize that the group receiving Methylprednisolone will experience smaller loss of knee-extension strength compared to the placebo-group, early after TKA.
Assess the safety, tolerability and pharmacokinetics of multiple doses of 10, 20, 30, and 40 mg of Hydrocodone Bitartrate Extended Release (HC-ER)capsules taken with food at steady state, in subjects with chronic, moderate to severe osteoarthritis (OA) pain.
Total knee replacement is one of the most commonly performed orthopedic procedures. As of 2010, about 600,000 total knee replacements were being performed annually in the United States and these numbers are rising. The normal knee joint functions as a complex hinge allowing primarily flexion and extension, rotation and gliding. The knee joint is made up of three compartments, the lateral, medial and anterior (patellofemoral). Damage to the cartilage of one or more compartments may be the result of osteoarthritis (idiopathic or post-traumatic), inflammatory arthritis (rheumatoid,psoriatic, etc.), a-vascular necrosis, tumors, or congenital deformities. Osteoarthritis and rheumatoid arthritis are the causes of the overwhelming majority of total joint arthroplasties. A successful Total knee arthroplasty(TKA) surgery includes: an accurate alignment( the mechanical axis in axial and rotational planes), as well as significant pain relief which improves function and quality of life. Incorrect alignment can lead to abnormal wear, premature mechanical loosening of the components and patellofemoral problems. The common techniques for Total knee replacement are: 1. Conventional method TKR 2. CT/MRI-based preoperative navigated TKR 3. Image-free intraoperative navigated TKR In our research we focus on the 3rd method using the Orthopilot navigation system Aesculap®, Tutlingen, Germany. This system is an active PC based guiding system that helps the surgeon decide on the accurate alignment and orientation of the implant and cutting surfaces of the bone and thus avoid incorrect alignment. We aim to compare between pre-operative and post-operative lower limb alignment (mechanical axis) in Aesculap based TKA using serview CT. Furthermore, we will try to examine the existence of a correlation between the CT scans and the Orthopilot navigation system output and assess the clinical outcome of the patient postoperatively. Our Hypothesis is that the intra-operative navigation system is accurate and correlated to CT images results, moreover, allows the surgeon to achieve a good mechanical axis and high clinical outcome,
Through a randomized controlled trial, we will compare the intravenous administration of tranexamic acid with the intra-articular application after a total hip arthroplasty through direct anterior approach. - RCT, prospective study - Academic-monocentric study - Clinical outcome measurements The postoperative blood loss will be the primary outcome. Secondary outcomes are 1. The rate of perioperative and postoperative blood transfusion 2. The number of blood units transfused 3. The length of hospital stay 4. Perioperative given intravenous isotonic fluid The Null-hypothesis is that there is no significant difference in postoperative blood loss between intra-articular and intravenous administration of TXA.
Nuclear Magnetic Resonance Therapy (NMRT) is gaining as a novel mode of therapy in osteoarthrosis. A prospective double blind randomised study of 100 patients was conducted to investigate efficacy of NMRT in the treatment of mild to moderate osteoarthrosis (OA) of the knee joint. The null hypothesis was that there is no benefit of NMRT over placebo in mild to moderate oteoarthosis of the knee.
