Filter by: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.
The purpose of this study is to determine if a shorter-acting spinal anesthetic called mepivacaine has advantages over a longer-acting medication called bupivacaine.
The aim of this study is to determine the clinical efficacy of gait rehabilitation robot through cortico-spinal-muscular pathway activation of the muscles remotely located from the end-effecter in patients after total knee arthroplasty.
Our participants will include 40 patients within one month of stroke, 43 patients who received total hip replacement or total knee replacement two to four weeks before. The participants will be randomly assigned to isokinetic, isotonic or isometric training groups. Outcome measures including isometric peak torque of hip/knee at 90 degree of flexion, peak torque of hip/knee at angular velocity of 60 degree/s and 120 degree/s, Short Form 36 (SF-36), the Timed Up and Go test, the Oxford Hip/knee Score, the plasma concentration of hsCRP, and the level of substance P in saliva will be collected at the beginning and 4 weeks after the training program. Statistical significant differences will be determined between the improvement of outcome measures of the isokinetic and the isotonic training groups.
This First-In-Human study will evaluate the safety and tolerability, pharmacokinetic profile, and pharmacodynamic effects of EP-7041, a novel Factor XIa inhibitor, following IV administration of single ascending doses in healthy normal volunteers, and following continuous IV infusions of multiple ascending doses in healthy normal volunteers.
Evolving reimbursement policies are driving health systems to improve quality and efficiency. Transitioning to an electronic health record (EHR) provided Dartmouth-Hitchcock Medical Center (DHMC) an opportunity to redesign staff roles and care path for Total Knee Replacement (TKR). The organization implemented a coordinated team-based care delivery model that integrated real-time measurement of: (1) compliance with trusted guidelines, (2) process of Shared Decision-Making (SdM), and (3) use of Patient-Reported Outcomes (PROs). The investigators present the implementation protocol and data.
The purpose of this study is to evaluate the influence of rapid recovery on sleep quality following total knee replacement surgery.
In total knee replacement operations, the surgeon uses techniques and instruments to guide the operation and ensure that all parts of the prosthesis (the artificial knee surfaces) are placed into the correct position. There are many techniques a surgeon can use to achieve accuracy in the operation. This study will compare the Principal Investigator's present precision-guided technique and instrumentation methods with a newly developed technique that uses a computer-based stereotactic guidance system. The purposes of the study are: 1.) to learn whether the use of the different guidance systems results in differences of accuracy of the placement of the prosthesis; 2.) to compare the length of time it takes an experienced joint replacement specialist to complete the operation using the different guidance systems; 3.) to learn whether there are advantages of either system in terms of the function and recovery of patients over the first year after surgery; and, 4.) to provide the manufacturer of the stereotactic guidance system with feedback on the technical ease of use and workflow ease of the system which may be used for training and education purposes and/or for planning further refinements to the system. The study will enroll up to 150 patients from Athens Orthopedic Clinic over 2 to 3 years.
The primary aim of this pilot study will be to develop a clinically meaningful, patient-centric, and pragmatic protocol to evaluate the comparative effectiveness of different strategies for achievement of the ideal balance between analgesia and functional mobility following total knee arthroplasty (TKA).
This is a prospective, single-center, single-blinded, randomized, case-control study. The study is conducted by a single investigator at an orthopedic surgery institute, with a minimum 6 week post operative follow-up period of TKA patients who receive Exparel compared with the surgeon's standard method (detailed below) for pain management intraoperatively.
