This study aims to compare quality of recovery after surgery and anesthesia between patients undergoing arthroscopic meniscectomy under general anesthesia with either propofol or remimazolam based total intravenous anesthesia. This study is a randomized trial with a 50% probability of being assigned to either group.

Patients and the investigator in charge of postoperative outcomes assessment will be blinded to group allocation.
