 The statistical analysis will compare preoperative and postoperative scores in terms of the use of analgesics, fall history, patient expectations satisfaction, KOOS HOOS, pain catastrophizing, the forgotten joint score and 30sec chair stand test. Significance will be set to 0.05. A Chi-square test will be used to investigate whether distributions of categorical variables differ from one another. Multivariable linear regression will be performed to examine the association between patient characteristics and the response rate to TKA and THA individually and TKATHA combined.
