NCT07548385
This is a prospective, randomized study. The purpose of this study is to evaluate if the addition of Suzetrigine, a new pain medication, to well established peri-operative pain regimen used for total knee replacement surgery will effect pain control. 1. Does Suzetrigine given pre-operatively decrease the total opioid consumed after total knee replacement surgery? 2. Dose Suzetrigine given pre-operatively decrease the visual analog pain scale pain scores after total knee replacement surgery? Study participants will be randomly assigned to receive either Suzetrigine medication or placebo medication.

The overall aims of this prospective, randomised, single-blinded controlled trial are to compare functional, radiological and clinical outcomes in Mako robotic-arm assisted cementless Total Knee Arthroplasty (TKA) versus Mako robotic-arm assisted cemented TKA.
NCT07023185
The purpose of this study is to compare pain score (Patient-Reported Outcomes Measurement Information System: PROMIS NRS Pain Subscale) between the control and cold/compression groups pre-surgically, daily after surgery for 14 days, then weekly after surgery for 3 months, and at 6 months post-surgery.
NCT06720012
The goal of this randomized study is to see if using patient-specific instruments (PSI) during total knee replacement surgery improves outcomes compared to standard instruments. The study focuses on adults with knee osteoarthritis who need knee replacement surgery. Specifically, it aims to answer the following questions: Does using PSI improve knee function and stability as experienced by the patient? Does PSI lead to more normal knee motion during bending and straightening? Does PSI result in at least as good tibial (shin bone) component fixation as standard instruments? Is PSI more cost-effective than standard instruments? Researchers will compare PSI with standard instruments in 70 patients. Half will receive knee replacement surgery using PSI, and the other half with standard instruments. Patients will be randomly assigned to each group. Participants will: Undergo knee replacement surgery with either PSI or standard instruments. Have a series of follow-ups, including assessments of knee function, satisfaction, and alignment of the knee implant, conducted before surgery and at 3 months, 1 year, 2 years, and 5 years after surgery. The study will include patients aged 40-75 with primary osteoarthritis, a body mass index (BMI) below 35, and no other major medical conditions that could impact surgery. Patients will also need to be willing to undergo necessary imaging, such as magnetic resonance imageing (MRI) scans and standing X-rays. Outcomes will be measured using various assessment tools, including the Oxford Knee Score, Knee Society Score, and a patient satisfaction survey. Researchers will also record surgery details, such as operating time, blood loss, and knee implant size. Imaging methods, including MRI, computed tomgraphy (CT) scans, and specialized X-rays, will be used to evaluate knee alignment and stability over time. The results of this study are expected to provide insights into whether patient-specific instruments offer clinical or economic advantages over traditional tools in knee replacement surgery.
NCT06241859
Spinal anesthesia is applied for patients undergoing total elective knee replacement surgery. It reduces rates of postoperative complications, improves postoperative pain management, rehabilitation is started earlier and patients more quickly return to the rhythm of ordinary life. According to the literature data, perioperative stress impacts part of cardiovascular complications and exacerbates postoperative pain. It is important that patients during the surgery under spinal anesthesia prefer to sleep. Thus, in order to reduce perioperative stress, patients during surgery are sedated. It is one of the most effective methods. On the other hand, deep sedation during surgery versus light sedation, is related to more frequent postoperative cognitive impairment and delirium. It leads to worse later surgery results and worse postoperative quality of life, increased risk of falling, prolonged duration of hospitalization, increased expenses.
NCT00927368
This is a randomized study which will compare three femoral nerve catheter insertion techniques. Subjects will be randomized into one of thee groups, Group 1: ultrasound guided femoral nerve catheter using a stimulation needle and stimulating catheter, .Group 2: ultrasound guided femoral nerve catheter using a stimulation needle, but non-stimulating catheter, or Group 3: ultrasound guided femoral nerve block without stimulation.
