Filter by:This study is a randomized-clinical-trial on 146 patients candidate for total knee arthroplasty (TKA) who were randomly allocated to three treatment groups, including 1) a cocktail consisting of bupivacaine, morphine, epinephrine, and ketorolac (n=48), 2) only epinephrine (placebo group) (n=49), and 3) 400mg celecoxib orally (control group) (n=49) using Random Allocation software. The injections and oral therapy were performed within 15 minutes before the surgical procedure. The study's primary outcome was the Knee Society Score (KSS) calculated at baseline, within six weeks and six months postoperatively. Range of motion (ROM) and Visual Analogue Scale (VAS) to assess pain intensity as the other primary outcomes were evaluated before the procedure, within 24 hours, 48 hours, and six weeks postoperatively.
The investigators hypothesized that intraoperative opioid consumption would be different between remimazolam and propofol if the ANI-guided remifentanil continuous infusion rate was adjusted when the depth of anesthesia was maintained at similar depths with remimazolam or propofol under total intravenous anesthesia. The purpose of this study is to compare the intraoperative remifentanil requirement in patients undergoing total knee arthroplasty when the intraoperative remifentanil dose adjustment was performed under the ANI guidance while maintaining a similar depth of anesthesia with remimazolam or propofol.
This study is aimed to provide a clinical and radiographic evaluation of 68 condylar-constrained Total Knee Arthroplasty (TKA) using a single type of prosthesis (Multigen Plus CCK configuration), alone or involving the AMF TT cones, in patients with joint instability or inadequate ligament function, both in complex primary and revision procedures.
This study will examine the impact of a new clinical decision support tool for rehabilitation after total knee arthroplasty (TKA). Typically, TKA rehabilitation is generic with most patients receiving the same dosage and contents of rehabilitation despite notable diversity among patients who undergo TKA. The investigators clinical support decision tool is designed to help physical therapists tailor rehabilitation treatments and dosages to the individual needs, goals, and preferences of Veterans recovering from TKA. This study has the potential to improve Veterans' functional recovery after TKA, while simultaneously reducing the average number of physical therapy visits Veterans attend after surgery by tailoring rehabilitation dosage based upon need. This will ensure the Veterans Health Administration (VHA) has the resources and capacity to provide adequate rehabilitation to every Veteran seeking TKA in the VHA system. Additionally, if successful, this clinical decision support tool could be used to improve outcomes and access for additional patient populations in the future.
Despite positive results following total knee arthroplasty (TKA), some patients are dissatisfied after recovery. Unfulfilled expectations is a key predictor of dissatisfaction. The aim of this study is to investigate if more patients fulfil or exceed their preoperative expectations one year after TKA when personal feedback on their PROs is given.
The aim of this study is to assess the long-term performance and safety of HLS KneeTec Deep Dish knee prosthesis when used in standard medical practice
The purpose of this study is to compare an FDA-approved medication for post-operative pain control (HTX-011) to the standard of care institutional practice for periarticular analgesia after primary total knee arthroplasty (weight based dosing of Ropivacaine, epinephrine and ketorolac diluted with saline). We are doing this research study to find out if this new medication provides superior pain control within 72 hours following surgery.
Motor-sparing analgesic interventions for patients undergoing total knee arthroplasty (TKA) are a key component of fast-track surgery. The investigators want to estimate treatments effects, inclusion rate, and feasibility of conducting a future randomized controlled superiority trial and to assess whether the short-term postoperative analgesic effect and ambulation after a Genicular - Infiltration Between Popliteal Artery and Capsule of Knee (iPACK) block in patients undergoing unilateral primary TKA is superior to Femoral triangle - iPACK block and Local Infiltration Analgesia (LIA). The study is a prospective, double-blind, triple-arm superiority pilot randomised controlled trial with a randomization rate 1:1:1.Group I will receive a Genicular - iPACK block, group II a Femoral Triangle - iPACK block and group III LIA. The primary study outcome is the proportion of patients that are able to mobilise (defined as walk 10 meters with assistance) with a numerical rating scale (NRS) of equal or less than 4 without the use of opioids at 4-6 hours after TKA. Secondary outcomes are efficacy (measured in NRS, total morphine consumption, total morphine titrations), functionality (quadriceps strength, timed-up-and-go, 6-minute walk test, inpatient falls), frequency of opioid related adverse events, discharge readiness, patient satisfaction, health-related quality of life, length of stay (LOS), complications after TKA and adverse events related to the study interventions.
Medial subperiosteal release is a commonly performed technique to improve surgical exposure and aid in joint balancing. This is a routine step during primary total knee arthroplasty that will be conducted on every enrolled patient. This is commonly performed both via scalpel (aka sharp medial peel) or electrocautery. The intervention will be randomly assigning subjects undergoing TKA into two groups, one receiving subperiosteal release using a scalpel (aka sharp medial peel) and the other via electrocautery.
Metal hypersensitivity is a recognized complication in some patients following total joint arthroplasty. This can result in a reaction to metal particles from the implants placed in the joint and cause tissue injury. The Evolution® NitrXâ„¢ (MicroPort Orthopaedics, Memphis, TN) knee implant was designed with the addition of a coating meant to create a barrier against the release of metal ions. The primary purpose of this study is to compare the Evolution and Evolution NitrX implant (implants your surgeon uses in total knee arthroplasty surgery). This study will compare the stability of these knee implants (any movement the implant makes after surgery) through the use of specialized xrays, called "radiostereometric analysis" (RSA for short). The investigators will also compare levels of circulating metal particles with blood draws and the effects of any circulating metal with MR imaging. The investigators will also be looking at the participants clinical outcomes using joint function and patient satisfaction questionnaires. A total of 50 patients will be enrolled into the study.
