Filter by:Methods National audit of a 60-day prospective observational cohort in the that the pre-defined postoperative complications at 30 days of follow-up in adult patients electively undergoing hip replacement surgery (HRS) or knee replacement surgery (KRS) with or without a program of Enhanced Recovery (ERAS: Enhanced Recovery after Surgery) with any level of protocol compliance (0-100%) Research Places Spanish Hospitals where these surgical interventions are performed usually Objectives To determine the incidence of Postoperative Complications per patient and procedure, regardless of the degree of adherence to ERAS protocols and its impact on the Hospital Stay and on postoperative complications including 30-day mortality Sample Size For an alpha error of 5% (95% confidence and an accuracy of 3% and estimating a number of patients with complications of 50%, the calculation of sample size yields 3012 patients, although the final sample size may be smaller depending on the proportion of complications detected. Inclusion criteria Patients over 18 undergoing elective HRS or KRS PTC regardless of its affiliation to a ERAS program and the level of compliance with protocol (from 0-100%) Statistical analysis Continuous variables will be described as mean and standard deviation, if it is a normal distribution, or median and interquartile range, if they are not distributed normally. The comparisons of continuous variables are performed by one-way ANOVA or the Mann-Whitney test, depending on proceed A univariate analysis will be carried out to test the factors associated with postoperative complications, hospital stay and death in Hospital. Univariate analyzes and logistic regression models will be constructed Hierarchical multivariate to identify the factors associated in a independent with these results and to adjust the differences in the factors of confusion. The factors will be introduced in the models based on their relationship with the univariate result (p <0.05), the biological plausibility and the low rate of missing data.
Prospective, multicenter, non-randomized study. Primary endpoint : to confirm the proper functioning of the device in vivo by analyzing intra and interobserver reproducibility of repeated measurements on healthy controls. Secondary endpoint : to describe the values of pelvic inclination while standing, sitting and lying in patients with severe hip osteoarthritis before and after total hip arthroplasty After signing the inform consent form: For the first endpoint (, 3 healthy volunteers of different morphotypes will have one consultation comprising : - a medical examination - 10 measurements of pelvic inclination in sitting position, 10 measurements of pelvic inclination in supine position and 10 measurements of pelvic inclination in standing position, each realized per three different operators. These measurements will be carried out with navigated ultrasound. For the secondary endpoint, 30 patients awaiting for a hip replacement surgical intervention will realized one consultation the day before the intervention, and one consultation at 2 months after surgery, each comprising : - a medical examination - 3 measurements of pelvic inclination (1 standing, 1 sitting and 1 supine). These measurements will be carried out with navigated ultrasound.
JointCOACH is a web-based communication platform that enables joint replacement patients to communicate with their care team via computer or smartphone throughout their episode of care, from the time that surgery is scheduled until at least 90 days postoperatively.
The purpose of this study is to assess the usefulness and results of orthopedic patients having access to a cell phone App called HealthLoop to utilize during the postoperative time period, compared to patients who have the usual postoperative management. The researchers want to investigate whether there any differences in outcomes and satisfaction in patients and providers.
A retrospective study will be performed to compare the incidence of revision procedures performed for the treatment of postoperative periprosthetic joint infection (PJI) between patients treated with a single preoperative antibiotic prophylaxis and patients treated with multiple shot antibiotic prophylaxis following primary arthroplasty of hip or knee. This study will be conducted in two phases. In phase 1 the investigators will evaluate which antibiotic prophylaxes (type of antibiotic and duration of prophylaxis) are regularly used in the Netherlands, by contacting all orthopaedic centres implanting total hip and total knee prostheses. In phase 2 the investigators will compare infection rate (defined as revision for infection as registered in the LROI database) between a single-shot and multiple shot antibiotic prophylaxis. Knee and hip primary arthroplasties will be considered separately.
The aim of this pilot study was to assess venous flow parameters in patients following total hip arthroplasty, comparing an intermittent pneumatic compression foot device with a portable neuromuscular electrostimulator device. Assessments were performed in a single sitting before hospital discharge, between days 1 to 4 post operatively. The total duration of participation for each patient who completed the study was approximately 2.5 hours.
The purpose of the study is the evaluation of the clinical and radiological short- to long-term safety and performance of the aneXys cup. The data will be used for an ongoing evaluation of the product safety and performance.
In this study we will investigate the relation between performed exercise dose and recovery after total hip replacement (THA). A dose-response relationship is hypothesized. It is the primary objective to indicate the preliminary efficacy of home-based rehabilitation using elastic band exercise on performance-based function after THA, based on the relationship between the performed exercise dose (objectively quantified time under tension summary dose) and the change in 40 meter maximal gait speed (performance-based function) from 3 (start of intervention) to 10 weeks (end of intervention) after surgery.
Cortisol is a hormone that increases after trauma or surgery and has circadian rhythm. It has a form that is increased in the morning and decreased in the evening. The investigators expected to be influenced by circadian rhythm according to the time of operation, and compared morning and afternoon surgery.
This project will be a descriptive, hypothesis-generating study. The aim is to identify risk factors for poor response to rehabilitation programs after TJR and use these to identify patients who are most susceptible to poor outcomes in order to optimise appropriate rehabilitations strategies and rationalising the distribution of health care resources.
