The Effect of Cold Application on Pain Level, Edema and Drainage Amount

In this study, we aimed to investigate the effect of cold application applied for 20 minutes every hour for 8 hours on the first day, second and third days after total hip arthroplasty with gel pads, on the pain level, edema and drainage amount of total hip arthroplasty patients. The main question\[s\]it aims to answer are: * Is there a difference between the pain levels of patients in the control and cold application arms? * Is there a difference between the knee edema of patients in the control and cold application arms? * Is there a difference between the amount of drainage of patients in the control and cold application arms? This study was planned as a prospective, parallel, two-arm (1:1) randomized controlled trial (RCT).
