A Prospective Randomized Controlled Trial Comparing Patient Outcomes Following Kinematic and Functional Alignment in Robotic-Assisted Total Knee Arthroplasty Using the VELYS System
Summary: This study aims to evaluate patient outcomes following robotic-assisted total knee arthroplasty using the VELYS system. Patients undergoing surgery will receive either kinematic alignment or functional alignment as determined by the operating surgeon as part of routine clinical care. Within each surgical technique group, patients will be randomly assigned to receive different implant insert types ...
Postoperative Effects of Femoral Triangle Block Versus Adductor Canal Block on Early Quadriceps Function After Total Knee Arthroplasty Under a Multimodal Analgesia Protocol: A Randomized Double-Blind Controlled Trial
Summary: The goal of this clinical trial is to compare the effects of femoral triangle block (FTB) and adductor canal block (ACB) on early quadriceps function after total knee arthroplasty (TKA). The main question it aims to answer is whether FTB causes more early quadriceps functional impairment than ACB under a standardized multimodal analgesia protocol. Researchers will compare FTB and ACB using a compo...
Cannabidiol for Postoperative Opioid Reduction in Primary Total Knee Arthroplasty - a Randomized, Two by Two Factorial, Double-blind, Placebo-controlled Clinical Trial
Summary: The goal of this study is to better understand how daily treatment with cannabidiol (CBD) affects the need for opioid pain medication, as well as pain, inflammation and other related symptoms, after knee replacement surgery. The information collected in this study is necessary to help understand whether CBD may be a useful medication before and/or after surgery. The study hypothesis is that CBD ex...
The Impact of Single-shot Adductor Canal Block Versus Continuous Femoral Nerve Block on Rehabilitation After Total Knee Replacement (AdORe - ACB)
Summary: Total knee replacement (TKR) is considered the most effective and safe method of radical treatment of late stages of knee osteoarthritis. A well-known problem of TKR is a severe postoperative pain syndrome, which is observed in more than 50% of patients. Femoral nerve block (FNB) is the gold standard for continuous postoperative analgesia after total knee replacement, as it is effective in reducin...
Impact of Irrigation Volumes in Revision Total Knee Arthroplasty (TKA) Surgical Washout: A Pilot Study
Summary: The purpose of this pilot study is to determine the volume of irrigation required to achieve macroscopic clearance of contaminants during a debridement, antibiotics, and implant retention (DAIR) procedure for periprosthetic joint infection (PJI) of the knee. Given the lack of robust data guiding irrigation volume in this setting, the investigator proposes to use the application of methylene blue d...
Evaluation of Movement and Muscular Alterations in Subjects With Severe Knee Osteoarthritis Who Are to Receive a Total Knee Replacement
Summary: Osteoarthritis (OA) is the most common joint disease. It is characterized by a progressive destruction of all the components of the joint, especially the cartilage. This leads to pain, loss of mobility and can be a major handicap for some patients. Gonarthrosis, or osteoarthritis of the knee, affects 30% of people between the ages of 65 and 75 and is one of the most disabling conditions. In the fi...
An Oral Methylprednisolone Taper Within a Multimodal Analgesic Regimen After Total Knee Arthroplasty: a Double-Blind Randomized Placebo-Controlled Trial
Summary: The purpose of this study is to evaluate the efficacy of an oral methylprednisolone taper on acute postoperative pain, function, opioid consumption, nausea, and complications following outpatient total knee arthroplasty (TKA). We hypothesize that administration of an oral methylprednisolone taper starting on postoperative day 1 (POD 1) following TKA will be associated with improved pain and decrea...
A Randomized Trial of Liposomal Bupivacaine, Ropivacaine With Perineural Dexamethasone, and Ropivacaine With Perineural Dexmedetomidine for Adductor Canal Block Combined With IPACK Block in Total Knee Arthroplasty
Summary: Effective postoperative pain management remains a cornerstone of enhanced recovery protocols following total knee arthroplasty (TKA). Inadequate analgesia not only compromises patient satisfaction but also impedes early mobilization and rehabilitation, thereby increasing the risk of perioperative complications. Current multimodal analgesic strategies frequently incorporate regional techniques, wit...
Comparison of the Analgesic Efficacy of Adductor Canal Block Versus Adductor Canal Block Combined With Local Anesthetic Infiltration Between the Popliteal Artery and the Capsule of the Knee (IPACK) in Patients Undergoing Knee Surgery
Summary: To evaluate the effectiveness of Adductor Canal Block and combined Adductor Canal plus IPACK block in reducing postoperative pain and analgesic requirements in patients undergoing knee surgery.
A Phase 3, Multicenter, Double-Blinded, Randomized Study to Evaluate REGN7508, a Factor XI Monoclonal Antibody, Versus Acetylsalicylic Acid for Prophylaxis of Symptomatic Venous Thromboembolism After Elective Total Knee Arthroplasty (ROXI-ASPEN)
Summary: This study is researching an experimental drug called REGN7508 versus Acetylsalicylic Acid (ASA) (each called study drug). The study is focused on adults undergoing elective, unilateral (one side) total knee replacement surgery. The aim of the study is to see how effective the study drug is at preventing Venous Thromboembolism (VTE) and other related diseases after total knee replacement surgery c...
Intraosseous Morphine Administration During Anterior Cruciate Ligament Reconstruction: A Randomized Control Trial
Summary: The purpose of this study is to determine if intraosseous (IO) morphine decreases pain and post-operative opioid use in patients undergoing anterior cruciate ligament (ACL) reconstruction.
A Phase 3, Multicenter, Randomized, Open-Label, Study to Evaluate REGN7508, A Factor XI Monoclonal Antibody, Versus Apixaban and Enoxaparin for Prophylaxis of Venous Thromboembolism After Elective Total Knee Arthroplasty (ROXI-APEX)
Summary: This study is researching an experimental drug called REGN7508 (called study drug). The study is focused on adults undergoing elective, unilateral (one side) total knee replacement surgery. The aim of the study is to see how effective the study drug is at preventing Venous Thromboembolism (VTE) and other related diseases after total knee replacement surgery. The study is looking at several other r...
