Cryotherapy Versus Standard Care in Reducing Opioid Consumption After Total Knee Arthroplasty

The goal of this clinical trial is to learn if compressive cryotherapy can reduce postoperative opioid consumption in patients undergoing primary total knee arthroplasty. It will also evaluate whether compressive cryotherapy improves postoperative recovery compared with standard care using conventional ice application. The main questions it aims to answer are: Does compressive cryotherapy reduce the total consumption of opioids during the first 7 days after total knee arthroplasty? Does compressive cryotherapy reduce postoperative pain and improve early recovery compared with standard cryotherapy? Researchers will compare compressive cryotherapy using the Game Ready® device with standard care using traditional ice packs to determine whether the intervention reduces opioid consumption and improves postoperative outcomes. Participants will: Be randomly assigned to receive compressive cryotherapy or standard cryotherapy with ice packs after surgery. Apply the assigned treatment four times per day during the first 7 postoperative days. Record daily pain levels using a visual analog scale (VAS) and document opioid consumption in a pain diary. Attend a follow-up visit on postoperative day 7 for evaluation of knee swelling, hematoma size, and recovery using the QoR-15 questionnaire.
