This study looked at whether simple distractions like a virtual reality headset, a squishy squeeze toy, or listening to poetry can help control pain after total knee replacement surgery. 140 adults were split into four groups to try one of these methods or receive standard care. …

This study tested whether telehealth (phone or video) nursing support after knee replacement surgery helps patients recover function, take care of themselves, and do daily activities. 64 adults who had knee replacement took part. The intervention group got 14 days of telehealth e…

This study looked at whether doing quadriceps (thigh muscle) exercises helps people who have had a total knee replacement. 36 adults between 40 and 60 years old, who were 1 month to 1 year post-surgery, took part. The goal was to see if these exercises could improve knee movement…

This study tested whether giving lidocaine through an IV works as well as a numbing shot near the knee (nerve block) for pain after knee replacement. 120 adults having knee surgery were randomly assigned to one of the two methods. The main goal was to see how much opioid pain med…

This study looked at whether duloxetine, a medication usually used for depression, can help reduce pain and the need for strong painkillers after knee replacement surgery. 241 adults having knee replacement took part. The goal was to see if adding duloxetine to standard pain trea…

This study tested whether dronabinol, a drug similar to cannabis, can help reduce the need for opioid painkillers after knee replacement surgery. 114 adults were randomly assigned to receive either dronabinol or a placebo before and after surgery. Researchers measured opioid use,…

This study tested two types of nerve blocks to control pain after total knee replacement. 62 patients received either a newer para-sartorial block or a standard femoral-sciatic block. Researchers measured how much extra pain medicine was needed and how well patients could move th…

This study tested a device called NEUROCUPLE™, a patch worn for 30 days after knee replacement surgery, to see if it reduces pain and the need for opioid painkillers. 156 adults having knee replacement took part, with half receiving the active patch and half a placebo patch. The …

This study looked at whether Emotional Freedom Technique (EFT), a therapy that involves tapping on specific body points, can help reduce pain and anxiety after total knee replacement surgery. 80 adults having their first knee replacement were included. Researchers measured pain a…

This small pilot study tested a treatment called genicular nerve radiofrequency ablation (RFA) for people with long-term knee pain after a total knee replacement. The treatment uses heat to calm specific nerves around the knee. Five adults aged 30 to 90 who had at least one year …

This study tested whether a smartphone app, used alongside standard recovery care, helps people recover better after hip or knee replacement surgery. 140 adults aged 18-80 who were scheduled for surgery took part. The app provided personalized rehab plans, progress tracking, and …

This study tested three different nerve blocks to see which provides the best pain relief after total knee replacement. Sixty adults having knee surgery under general anesthesia received one of the blocks. The main goal was to measure how long it took before they needed extra pai…

This study looked at whether a relaxation technique called Benson's relaxation exercise could help people who had total knee replacement surgery feel less anxious and less afraid of moving their new knee. 64 patients took part. The results showed that doing this simple relaxation…

This study tested whether a hands-on practice session before knee replacement surgery could help patients feel less afraid and worried. 48 adults scheduled for knee replacement were split into two groups: one received standard education, the other a simulation-based session. Rese…

This study looked at 120 people having knee replacement surgery to see if using 10 mL or 20 mL of numbing medicine for a nerve block (popliteal plexus block) works better for pain. The goal was to reduce the need for strong painkillers (opioids) in the first 24 hours after surger…

This study looked at 118 people who had a second knee replacement surgery using the Medacta GMK Revision system with 3D metal cones. The goal was to see how well the knee worked and how safe the system was after at least one year. Researchers collected patient reports on pain, fu…

This study looked at 80 adults aged 45-85 having knee replacement surgery under spinal anesthesia. Researchers measured heart electrical activity (ECG) before and after the anesthesia to see if it changes. The goal was simply to observe and learn, not to treat or cure any conditi…

This study looked at 110 knee replacement patients to see if heart rate variability (HRV) could predict a sudden, intense pain called rebound pain after nerve blocks wear off. Researchers measured HRV before and after surgery using a chest monitor. The goal is to help doctors per…

This study looked at whether removing a surgical drain before or after the first physical therapy session affects recovery after total knee replacement. Researchers followed 207 adults with knee osteoarthritis who had knee replacement surgery. The goal was to see if drain timing …

This study looked at 140 adults having knee replacement surgery to see if spinal or general anesthesia changes the heart's electrical signals differently. Researchers measured heart activity before and after surgery using a standard ECG. The goal was to understand how the choice …

This study followed 294 knee replacement patients to see how often they experienced a sudden, severe pain when their nerve block wore off. Researchers found that many patients reported high pain levels within 12-24 hours after surgery. The goal was to better understand this 'rebo…

This study looked at 33 people who had knee replacement surgery to see if checking their recovery at 6 hours after surgery is as good as checking at 24 hours. The goal is to find the best time to safely send patients home. Researchers used a standard scoring system to measure how…

This study looked at whether placing a drain after knee replacement surgery affects how much hemoglobin drops and whether a blood transfusion is needed. 102 adults having knee replacement took part, with half getting a drain and half not. Researchers measured hemoglobin before su…

This study looked at 145 people who had a knee replacement and later got an infection. Doctors compared four different surgeries to see which one best prevented the infection from returning or needing another surgery. The goal was to help surgeons choose the best treatment for ea…
