Prehabilitation is defined as a process of improving the functional capability of a patient prior to a surgical procedure so the patient can withstand any postoperative inactivity and associated decline. In other words, to get you to a better place physically before an operation. Generally, the more fit and active you are going into a surgical procedure, the more likely you are to retain a higher level of function after. It is important for you to know and work on any functional deficits prior to your operation.
