Filter by:As tranexamic acid (TXA) becomes more prevalent, all patients are receiving the same dose regardless of their pre-operative risk of transfusion. Therefore the aim of the study is to determine whether or not repeated dosing of oral TXA reduces the post-operative reduction in hemoglobin, hematocrit, number of transfusions, and post-operative blood loss following primary TKA and THA surgeries in patients with low pre-operative hematocrit and high risk for transfusion. The investigators hypothesize that a multi-dose TXA regimen will significantly minimize post-operative blood loss and transfusion requirements compared to the use of a single dose regime.
This is a Phase 2, randomized, single-blind, active-controlled dose-ranging study in subjects scheduled to undergo total knee arthroplasty (TKA).
Does the use of periarticular Exparel in total knee arthroplasty prove to more effectively manage post operative pain control than another local analgesic, Ropivacaine, when both are used as part of a multimodal pain management approach? The investigators hypothesize that Exparel, a bupivacaine liposomal injectable suspension, will improve total knee arthroplasty postoperative pain with significant improvement of early function outcomes.
This study compares the long-axis and short-axis technique of continues adductor canal block for total knee replacement surgery. Half participants will receive long-axis catheterization, while the other half will receive short-axis catheterization.
This study investigates single injection adductor canal block (ACB) with or without intravenous dexamethasone and adductor canal catheter for pain management of total knee arthroplasty. This is a non-inferiority trial seeking to determine whether single injection ACB with dexamethasone is "no worse" than a continuous catheter.
Early total knee arthroplasty (TKA) implant systems most frequently used an all-polyethylene cemented tibial component1. Based on finite-element analysis studies reporting superior force distribution compared with conventional all-polyethylene components, metal-backed tibial baseplates have dominated the TKA implant market since the middle of the 1980's2. These modular implants provided excellent long-term implant survivorship3. As TKA became increasingly successful, younger patients increasingly became eligible. Increasing life expectancy has raised the concern that cemented TKAs may not withstand prolonged use, particularly in younger patients4. Patients younger than 65 years are projected to account for more than 50% of patients undergoing TKA by 2016 and to more than 50% of patients undergoing revision surgery by 2011. The number of total knee revisions in the United States is expected to increase from 38,300 in 2005 to 268,200 in 20305. Many authors have reported excellent and equivalent results of cemented and cementless TKA6-8. Despite these encouraging reports, the major concern with cementless TKA has been the tibial component, and, therefore, the preference for many surgeons still remains to cement the tibial component9,10. The femoral component may be the most suitable for cementless fixation11-13. However, the best femoral method of fixation is still being discussed. Currently, the decision to cement or not to cement the femoral component is based on the surgeon's preference14. The current study was designed to compare the hybrid NexGen LPS (Zimmer Inc, Warsaw, IN) and the cemented NexGen LPS. The purpose of this study is to establish whether the hybrid NexGen LPS leads to equally successful results as the cemented TKA gold standard
This study will evaluate blood flow restriction training as a rehabilitation modalities following total knee arthroplasty in order to determine if patient reported outcomes and objective functional outcomes can be improved through post-operative rehabilitation compared to standard physical therapy modalities currently in use.
This study will evaluate if the addition of dexamethasone to a local infiltration analgesia mixture will improve functional outcomes following total hip and knee arthroplasty.
The purpose of this study is to compare a single shot block, 24 hours, and 48 hour continuous catheter nerve block done via the adductor canal method in adult patients who have under gone total knee arthroplasty. Visual analogue scores, opioid consumption, time to up and go, ambulation, manual muscle tests, and Tinetti scores up to 72 hours post operatively will be used for comparison.
The purpose of this study is to determine if home-based therapy with monitoring via telemedicine can overcome many barriers to compliance and improve rehabilitation. Patients undergoing total knee arthroplasty will be followed for 10 weeks during their outpatient physical therapy course. Subjects will undergo standard physical therapy or physical therapy paired with InterACTION for 10 weeks.
