TOTAL KNEE ARTHROPLASTY

This study looks at whether using virtual reality (VR) during knee exercises after total knee replacement can lower pain and anxiety and increase comfort. About 102 people who had their first knee replacement will be split into two groups: one using VR and one not. Researchers wi…

This study tests whether an AI-based smartphone app can help people recover faster and more safely after hip or knee replacement surgery. About 106 adults will either use the app for 12 weeks of home exercises or follow the same exercises from a paper brochure. The goal is to see…

This study tests a new nerve block method (quadri-block) against the standard approach for pain relief after total knee replacement. The goal is to see which method helps patients recover better in the first 24 hours. 100 adults with knee arthritis will be randomly assigned to on…

This study tests whether a numbing injection (genicular nerve block) given before knee replacement surgery can lower pain and the need for strong painkillers afterward. About 70 adults with knee osteoarthritis will be randomly assigned to get either the nerve block or a placebo i…

This study compares two types of nerve blocks to see which provides better pain relief and faster recovery after total knee replacement. Fifty adults having knee surgery will receive one of two block combinations. The goal is to improve movement and reduce pain after the operatio…

This study tests a nursing program based on the ABC-X model for 117 adults aged 30-65 having their first knee replacement. The program helps patients and families manage stress, use support resources, and think positively about recovery. Researchers will measure psychological res…

This study tests whether adding a specific nerve block (biceps femoris short head block) to standard pain management reduces the need for morphine after knee replacement surgery. Sixty adults scheduled for knee replacement will be randomly assigned to receive either the extra ner…

This study tests whether a surgeon can give a pain-relieving nerve block during knee replacement surgery as effectively as an anesthesiologist using ultrasound. 48 adults having both knees replaced will get one type of block on each knee. The goal is to see if the surgeon's metho…

This study compares two pain relief methods after total knee replacement: injecting numbing medicine into the knee area versus blocking four nerves in the leg. The goal is to see which method better controls pain and reduces the need for strong painkillers. About 80 adults having…

This study tests whether a single dose of methadone given just before total knee replacement surgery can improve pain control and reduce the amount of painkillers patients need afterward. About 192 adults aged 21 to 75 having a knee replacement will take part. Researchers will tr…

This study looks at whether doing exercises that combine physical movement with mental tasks (like talking while walking) can improve pain, balance, and daily function after total knee replacement. About 40 adults aged 50-65 who had a knee replacement will be split into two group…

This study looks at whether using a stress ball or doing breathing exercises can reduce pain and keep vital signs stable when a surgical drain is removed after knee replacement. About 105 adults will be split into three groups: stress ball, breathing exercises, or standard care. …

This study looks at whether taking the drug tranexamic acid for up to 7 days after knee replacement surgery can improve pain, function, and how well the knee bends. About 351 adults having a first knee replacement will be randomly assigned to receive the drug or a placebo. The ma…

This study looks at whether using AI-made videos to show patients what happens during knee replacement surgery can lower their anxiety and fear of moving. About 150 adults aged 55 and older who are scheduled for knee replacement will take part. Half will get standard education, a…

This study tests whether adding a new type of nerve block (biceps femoris short head block) to the usual pain management approach can reduce pain and improve recovery after total knee replacement. About 132 adults having knee replacement will be randomly assigned to receive eithe…

This study will follow 99 adults aged 50 to 80 who are having knee replacement surgery. It aims to see if giving the steroid dexamethasone (by mouth or IV) around the time of surgery helps reduce pain, improve mobility, and lessen nausea compared to not giving it. The drug is giv…

This study tests a new 3D-printed device that measures how balanced the knee is during total knee replacement surgery. About 50 adults having their first knee replacement will take part. Surgeons will use the device alongside their usual methods, but it won't change how they perf…

This study looks at whether older adults (70+) experience changes in thinking skills, like attention and processing speed, after having hip or knee replacement surgery and going home the same day. About 48 participants will take a short cognitive test before surgery and again on …
