It will also assess whether this treatment can reduce opioid use and improve recovery.\n\nThe main questions it aims to answer are:\n\n* Does a preoperative GNB reduce pain during movement 24 hours after surgery compared with placebo?\n* Does it reduce opioid consumption and improve physical activity and functional outcomes after surgery?\n\nResearchers will compare patients receiving a GNB to patients receiving a placebo injection to see if the nerve block improves postoperative pain and recovery.\n\nParticipants will:\n\n* Be randomly assigned to receive either a GNB or a placebo injection before surgery\n* Undergo standard knee replacement surgery and postoperative care\n* Report pain levels at regular intervals after surgery\n* Complete questionnaires on function, quality of life, and recovery\n* Wear an activity monitor to measure physical activity after surgery\n* Attend follow-up assessments at 1 week, 1 month, and 3 months",[28,29,30],"Osteoarthritis (OA) of the Knee","Total Knee Arthroplasty","Genicular Nerve Block",[32,33,34,35,36],"Osteoarthritis","Knee","Knee osteoarthritis","Total knee arthroplasty","Genicular nerve block","NOT_YET_RECRUITING","2026-05-11",{"date":40,"type":41},"2026-05-15","ACTUAL",{"date":43,"type":22},"2026-06-01",{"date":45,"type":22},"2029-06-01",{"name":47,"class":48},"Helse Møre og Romsdal HF","OTHER_GOV"]
