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.
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.
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.
Osteoarthritis (OA) is a very common condition in the elderly population. Treatment for end-stage OA is total knee Replacement (TKR)
Biomedical implant metals are reactive when in contact with body fluids. Some reactions may adverse the biocompatibility character of the material and should be studied. This can be achieved by direct measurement through electrochemical, gravimetric, spectrophotometric and surface analysis of reaction occurring at the interface between functionalized metal samples and body fluids (synovia) directly extracted from patients. The general aim of this project is to contribute to develop a comprehensive vision of interfacial reactions occurring on biomedical alloy surfaces exposed to human synovial fluid and to link them to clinical data
Primary Aim: To examine the superior efficacy of ACT versus Attention Control (AC) on postoperative pain intensity and functioning in at-risk Veterans undergoing TKA. Changes in pain intensity and functioning from baseline to 6 weeks, 3 months and 6 months post-TKA will be compared. Level of pain intensity will be measured using the BPI Pain Severity Subscale and level of functioning will be measured using the KOOS Activities of Daily Living and Quality Of Life Subscales. Secondary Aims: A) To examine the superior efficacy of ACT versus AC on the severity of anxiety and depressive symptoms and improvements in coping skills. Changes from baseline to 6 weeks, 3 months and 6 months post-TKA will be compared. Anxiety and depressive symptoms will be measured with the Hamilton Rating Scales (Ham-A and Ham-D, respectively). Coping skills (i.e. Pain Acceptance and Engagement in Values-Based Behavior) will be measured with the Chronic Pain Acceptance Questionnaire and the Chronic Pain Values Inventory. B) To evaluate whether decreases in distress-based symptoms and increases in coping skills mediate changes in pain and functioning at 6 months in Veterans receiving ACT. Changes in anxiety symptoms, depressive symptoms, pain acceptance and engagement in values-based behavior from baseline to 6 weeks and 3 months will be used as potential mediators for changes in pain and functioning at 6 months. Exploratory Aim: Describe the pharmacological and non-pharmacological strategies Veterans are using to manage pain and their perceived helpfulness. This will provide insights into the effects of the current opioid restrictions on pain management strategies. These strategies & their perceived helpfulness will be assessed using the Pain Management Strategies Survey at baseline, 6 weeks, 3, and 6 months.
A prospective randomized control trial will be conducted at Good Samaritan Hospital and TriHealth Evendale Hospital. Subjects will receive total hip or knee surgery and follow-up via standard care at the discretion of the treating physician or the experimental study arm in which all patients will undergo the integrated care pathway.
The main objective of the present study is the evaluation of the kinematic parameters of gait and distribution of the load, recorded thruogh a sensorized treadmill, on lower limbs in patients at 1 year from Total Hip Replacement or Total Knee Replacement. The secondary objective is to evaluate the effects of gait training with biofeedback by means of a sensorized treadmill in patients with asymmetry of the kinematic parameters of the step and of distribution of the load on the lower limbs.
The aim of total knee arthroplasty is to achieve best patient functional outcomes, improve patient pain score and satisfaction. Synovial proliferation is a common finding in arthritic knees. Surgeons can't decide if synovectomy is a crucial step in the operation. Studies didn't prove the clear benefits of synovectomy. We are aiming to perform a randomized clinical trial trying to reach the best evidence in that matter.
