Hip and knee replacements are indicated to improve long-term quality of life and pain. These long-term results may depend on the quality of the initial postoperative recovery. However, early postoperative health status after total hip arthroplasty (THA) and total knee arthroplasty (TKA) is not accurately described. Through this retrospective study, the investigators wanted to describe the perioperative state of health monitored using the QoR-15 questionnaire for THA and TKA patients from the perioperative moment to postoperative day 28.
