Filter by:Backwards walking has been shown to improve balance and walking in patients who have knee Osteoarthritis. It is not known if these benefits may also be seen after surgery in patients who have had a hip or knee replacement because of Osteoarthritis. This study will look to see if it is possible to conduct a bigger study into how effective backwards walking may be after joint replacement. Patients who come to the Nuffield Orthopaedic Centre in Oxford for a hip or knee replacement will be invited. They will be placed into one of two groups at random: a group where they have a course of physiotherapy plus a backwards walking programme or a group where they have a course of physiotherapy. The physiotherapy will last for 12 weeks and those who take part will have two study assessments. The first will be before any treatment and patients will complete five measures and also be issued with a simple tick box diary to complete over the 12 weeks. The second assessment will be after the treatment and will involve the same five measures and the diaries will be collected in. Participants at this assessment will also be asked if they would like to take part in an interview for the study. This is to see what the patients thought of the study. During the study the researcher will record things such as how many patients say 'yes' to the study and how many participants drop out of the treatment, to understand if a bigger study could take place.
The study will analyze differentially regulated genes involved in oxidative stress and toxicology in peripheral blood mononuclear cells (PBMCs) of patients who underwent arthroplasty under three different anesthetic methods. The investigator hypothesized that anesthesia procedures trigger toxicity, thus inducing changes in the messenger ribonucleic acid (mRNA) profile. The results may provide a more profound understanding of the molecular mechanism of anesthesia and in overcoming the adverse effects arising from their use.
This is a randomized control trial that will investigate whether a collared hip replacement implant provides greater stability compared to a collarless option. Stability will be measured by implant migration with radiostereometric analysis (RSA) imaging. Secondary objectives will be to compare function, quality of life and cost between the two implant types. We will also compare between two different surgical approaches, the direct anterior and direct lateral.
This investigation is planned to compare the incidence and severity of postoperative sore throat according to the use of sevoflurane or desflurane.
This investigation is planned to compare the incidence and severity of postoperative sore throat according to the dose of remifentanil.
In the last years, a lot of surgical fast track programs (SFTP) have been created and developed. This is due to the steady growing number of interventions on knee and hip; after the surgical treatment, a period of physical rehabilitation (PR) is established to be useful and effective, it usually takes 2-3 weeks. The recovery of strength, range of motion (ROM), independence, the reduction of pain and disability are the aims of PR. With the SFTP and a specific rehabilitation program named fast track rehabilitation (FTR) these times can be reduced. First of all because the length of stay (LOS) it's also caused by organizational problems of the hospitals, not only for the factors related to the patient. It's already been demonstrated that an early mobilization decreases the risk of thromboembolic complications and of pain, furthermore an early rehabilitation increase the patient autonomy and reduces the lost of residual abilities. Moreover a PR program studied for fast track patient will reduce minimum by a 50% the LOS in hospital, decreasing so the sanitary efforts that are always a problem for all the countries. The aim of this study is therefore to propose a fast track rehabilitation program based on an 8 days program for hip and knee arthroplasty being operated with an SFTP.
The overall objective of this study is to test for perturbations in intraoperative electroencephalogram (EEG) , cerebral blood flow (CBF), cerebral metabolic rate of oxygen consumption (CMRO2), oxygen extraction fraction (OEF), and serum and cerebral spinal fluid biomarkers associated with delirium in high risk population having elective hip arthroplasty at Penn Presbyterian Medical Center (PPMC).
Patients were recruited at the scheduled preoperative visit for hip or knee arthroplasty. If the haemoglobin (Hb) level was below 13 g/dl with no contraindication to iron supplementation the patients were randomized to the oral or intravenous (IV) group. The oral group received 160 mg ferrous glycine sulfate daily during the month prior surgery, associated with 3 epoetin alpha (EPO) injections (40 000 IU subcutaneous on day - 21, day - 14 and day-7). The IV group received ferric carboxymaltose 1000 mg IV in 15 minutes one month before surgery, associated with 3 EPO injections. Primary efficacy endpoint was the change in Hb level from the day of the preoperative visit to the day before surgery (day-1). Secondary endpoints comprised the Hb level on day 3 and 5 after surgery, allogenic transfusion during and after surgery, and the change in iron indices from the day of the preoperative visit to day - 1.
Leg length discrepancy (LLD) is a complication of THA and may result in patient dissatisfaction, gait disorder, greater trochanter pain, low back pain. In the literature, LLD is reported to vary widely among studies e.g. 6 to 35 mm. However, the threshold at which a LLD is clinically important is still a matter of debate. The aim of this study was to determine the influence of non-corrected LLD after THA on patients' reported hip function and quality of life. This prospective cohort study was conducted at Sundsvall Teaching Hospital in Sweden after it was approved by the regional ethics committee at Umeå University (No. 07-052M and No. 12-287-32M). Between September 2010 and April 2013, all patients with unilateral primary osteoarthritis (OA) treated with THA were considered for inclusion. Informed consent was obtained from all patients. Patients with secondary OA, previous spinal, pelvic, or lower limb injuries or fractures were excluded. The primary outcome measure was the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index that measures functional outcome (ref). The secondary outcome measure was the EQ-5D and visual analogue scale (VAS) scale. Patients were assessed preoperatively and at follow-up at 1 year postoperatively. The posterolateral approach was used in all operations. LLD was measured on the postoperative x-rays. patients were divided into three groups: shortening group where the operated leg was more than 5mm shorter compared with the contralateral side, the restoration control group where the operated leg was within 5mm shortening and 9mm lengthening compared with the contralateral side, and the lengthening group where the operated leg became more than 9mm longer compared with the contralateral side.
The purpose of this study is to compare a single preoperative dose of 1g of tranexamic acid (TXA) versus a preoperative dose of 1g of TXA followed by a continuous infusion of 1g over height hours on blood loss.
