Filter by:Every medical intervention requires informed consent. Informed consent may include comprehensible information about the necessity and kind of the intervention, material risks and consequences or alternative treatments. Practitioners frequently use consent forms to support the physician-patient conversation and to document informed consent. Studies show, that informed consent forms used in practice, are heterogeneous. This study aims at investigating the effects of evidence-based informed consent forms for Total Knee Replacement and related anaesthesia procedures. Evidence-based informed consent forms include best and latest evidence in lay language. It is hypothesized that evidence-based informed consent forms - compared to standard consent forms - improve patients' risk perception, reduce anxiety of complications and reduce the nocebo effect (unspecific negative effects caused by the way of communicating risks). To compare evidence-based and standard informed consent forms, an Interrupted Time Series pilot study will be conducted. It is planned to include 220 patients, who are scheduled for elective total knee replacement surgery. The accompanying qualitative analyses ensure that the (German) legal requirements for informed consent are met.
Rehabilitation after primary knee or hip arthroplasty may include performing exercises with a physiotherapist. For patients who can work well with a computer, tablet or smartphone, it is now possible to use a mobile application (e.g. moveUp) to carry out a large part of the exercises more independently. This is done with online guidance by a physiotherapist via a mobile application that is CE marked in Europe. This study will investigate whether the effect of the mobile application on knee or hip rehabilitation and quality of life is equal to that of standard care (i.e. without the use of a mobile application).
The purpose of this study was to determine 1) if pregabalin, when given 37.5 mg twice on the day before surgery, would be effective in reducing the early postoperative side effects including dizziness, nausea, vomiting and sedation of receiving pregabalin 75mg two hours pre-operatively and 75mg per day until the third postoperative day; and 2) whether this intervention affected the opioids consumption, and independent transfers at six hours post-op, time to readiness for independent transfers, time to readiness for discharge and pain or not.
Following a prosthetic knee joint infection, two types of operative approach can be undertaken to treat the infection: a one-stage or two-stage revision operation. Both approaches are widely used and are good at treating infection but we don't know which has the best long-term outcomes for patients. This trial aims to assess the feasibility of conducting a randomised controlled trial to evaluate whether treating a prosthetic knee infection with one-stage revision surgery gives a better outcome than two-stage revision surgery in terms of patient function and pain, and cost-effectiveness.
The number of knee arthroplasties performed each year is constantly increasing. Although the outcome is generally favourable, 10-20% do not achieve a satisfactory clinical result. This study evaluates the effectiveness of immersive virtual reality rehabilitation in older people who have undergone knee arthroplasty surgery. The 6 Meter Walking Test is used to determine the improvement of patients after the procedure.
The randomised clinical trial investigates the effect of using a clinical decision support system (CDSS) aiming to provide the patients and surgeons with greater transparency concerning the obtainable changes in function and health related quality of life (HRQoL) when patients are to decide if they should undergo hip- or knee replacement surgery.
This study will prospectively investigate the efficacy of Adductor canal block with periarticular infiltration Vs Adductor canal block, Periarticluar infiltration and Sensory posterior articular nerve of the knee block in patients undergoing total knee arthroplasty. The study will aid in answering question whether SPANK block is an effective adjunct in preventing posterior knee pain without causing motor blockade.
The goal of this study is to utilize physical activity monitoring to determine the trajectory of normal recovery as it relates to a patient's ability to get up and get moving. From this work, we hope to be able to define the range in patients' physical activity following knee replacement surgery, and thus, give clinicians a tool and the methodology to identify patients whose recovery is not progressing as quickly as expected. Data from physical activity monitors will allow the research team to identify how active patients are, how vigorous that activity is, and how well that activity correlates with standard and commonly used patient questionnaires.
The study aims to assess the effect of spinal anaesthesia against a general anaesthesia with a femoral block, with respect to the incidence of chronic pain following a total knee replacement. It will also focus on genetic factors and their influence on chronic pain.
There has been a wide variety of use of anaesthetic agents along with adjuncts during subarachnoid block. The quest for attaining adequate analgesia and anaesthesia has always been shadowed by the concurrent deleterious effect of the anaesthetic agent. Ropivacaine as an anesthetic agent has proven to meet the desired goals of anaesthesia while minimizing the potential side effects. The addition of different adjuncts has shown to enhance the analgesic property, prolong the duration of sensory blockade and decrease the dose related adverse effects of the local anaesthetics. Fentanyl in this regards has also shown some promising effects. Thus we compare the use of ropivcaine as a single agent versus ropivacaine along with an adjunct (Fentanyl) to attain the desired anesthetic effect while minimizing the associated side effects.
